Transmission within countries with endemic infection is focal antibiotic resistance research grants buy generic doxycycline canada, but if a child comes from a country with endemic Chagas disease or has received a blood transfusion in a country with endemic disease antibiotic cream for impetigo purchase doxycycline line, testing for Trypanosoma cruzi should be considered antibiotic plants proven 200 mg doxycycline. Serologic testing should be performed only in children 12 months or older because of the potential presence of maternal antibody infection prevention week 2014 order doxycycline amex. Diseases such as typhoid fever, malaria, leprosy, or melioidosis are encountered infrequently in internationally adopted children. If the child came from a country where malaria is present, malaria should be considered in the differential diagnosis (see Malaria, p 528). Measles elimination has been achieved only in the Americas; transmission continues in other parts of the world. All people born after 1957 should receive 2 doses of mea sles-containing vaccine after the age of 12 months in the absence of documented measles infection or contraindication to the vaccine (see Measles, p 535). Clinicians should be aware of potential diseases in internationally adopted children and their clinical manifestations. In most cases, the longer the interval from adoption to development of a clinical syndrome, the less likely the syn drome can be attributed to a pathogen acquired in the country of origin. Standard wound cleansing and care is indicated; such wounds rarely require closure. A tetanus toxoid containing vaccine, with or without Tetanus Immune Globulin, should be considered as appropriate for the age, the severity of the injury, the immunization status of the exposed person, and the poten tial for dirt or soil contamination of the needle (see Tetanus, p 773). Tetanus and diphthe ria toxoids (Td) vaccine should be used if the patient has already received all necessary doses of pertussis containing vaccine. Pediatric injuries from needles discarded in the community: epidemiology and risk of seroconversion. Children who have needle stick injuries and who have not completed the 3-dose hepatitis B (HepB) vaccine series should receive a dose of HepB vaccine and, if indicated, should be scheduled to receive the remaining doses required to complete the schedule. Preventing Needlestick Injuries Needlestick injuries of both children and adults can be minimized by implementing pub lic health programs on safe needle disposal and programs for exchange of used syringes and needles from injection drug users for sterile needles. The American Academy of Pediatrics supports needle exchange programs in conjunction with drug treatment and within the context of con tinuing research to assess their effectiveness. In addition, children should be educated to avoid playing in areas known to be frequented by injecting drug users and to avoid play ing with discarded needles and syringes. Bite Wounds As many as 1% of all pediatric visits to emergency departments during summer months are for treatment of human or animal bite wounds. An estimated 5 million bites occur annually in the United States; dog bites account for approximately 90% of those wounds. The rate of infection after cat bites is as high as 50%; rates of infection after dog or human bites are 10% to 15%. Although postinjury rates of infection can be minimized through early administration of proper wound care principles, the bites of humans, wild animals, or nontraditional pets potentially are sources of serious morbidity. Parents should be informed to teach children to avoid contact with wild animals and should secure gar bage containers so that raccoons and other animals will not be attracted to the home and places where children play. Nontraditional pets, including ferrets, iguanas and other reptiles, and wild animals also pose an infection as well as an injury risk for children, and their ownership should be discouraged in households with young children. Potential transmission of rabies is increased when a bite is from a wild animal (especially a bat or a carnivore) or from a domestic animal with uncertain immunization status that cannot be captured for adequate quarantine (see Rabies, p 658). Because of the small number of prospective controlled studies of the topic, the con sideration of whether to suture closed bite wounds remains controversial except when Table 2. Management of Human or Animal Bite Wounds Category of Management Management Cleansing Remove visible foreign material Cleanse the wound surface with clean water or saline. Antimicrobial or anti-infective solutions offer no advantage and may increase tissue irritation. However, published data support surgical closure with interrupted sutures or adhesive strips of recent, apparently uncontaminated, low-risk lesions after thorough wound cleansing, irrigation, removal of foreign materials, and debridement. Bite wounds on the face seldom become bacterially infected, but if a wound has important cosmetic considerations, it should be closed whenever possible. Surgical closures can be performed at the time of initial management (primary) or delayed until the patient has received a brief course of antibiotic therapy (delayed primary closure). Smaller, cosmetically unimportant wounds can be cleansed and allowed to heal by secondary intent. More complicated injuries should be managed in consulta tion with an appropriate surgical specialist. Approximation of margins and closure by delayed primary or secondary intent is prudent for infected nonfacial wounds. To minimize risk of infection, bite wounds should not be sealed with a tissue adhesive, no matter their age or appearance. Limited data exist to guide short-term antimicrobial therapy for patients with wounds that do not appear infected. Children at high risk of infection (eg, children who are immunocom promised or who have crush injuries or deep tissue, compartment, or joint penetra tion) should receive preemptive antimicrobial therapy. Guidelines for initial choice of antimicrobial therapy for human and animal bites are provided in Table 2. The treatment of choice following most bite wounds for which therapy is provided is amoxicillin-clavulanic acid (Table 2. Treatment of the child with a serious allergy to penicillin and a human or animal bite wound is problematic. Extended-spectrum cephalosporins, such as cefotaxime or ceftriaxone parenter ally or cefpodoxime orally, do not have good anaerobic spectra of activity but can be used in conjunction with clindamycin as alternative therapy for penicillin-allergic patients who can tolerate cephalosporins. The duration of treatment for bite wound-associated bone infections is based on location, severity, and pathogens isolated. Physicians should be aware of the epidemiology of tickborne infections in their local areas. Prevention of tickborne diseases is accomplished by avoiding tick-infested habitats, decreasing tick pop ulations in the environment, using personal protection against tick bites, and limiting the length of time ticks remain attached to the human host. Most ticks prefer dense woods with thick growth of shrubs and small trees as well as along the edges of the woods, where the woods abut lawns. For homes located in tick-prone areas, risk of expo sure can be reduced by locating play equipment in sunny, dry areas away from forest edges, by creating a barrier of dry wood chips or gravel between recreation areas and forest, by mowing vegetation, and by keeping leaves raked and underbrush cleared. This species may be found in cracks and crevices of housing or in animal housing or bedding. Pants should be tucked into boots or socks, and long-sleeved shirts should be buttoned at the cuff. Permethrin (a synthetic pyrethroid) is a contact pesticide and tick and insect repellent and can be sprayed onto clothes to decrease tick attachment. Permethrin should not be sprayed directly onto skin, and treated clothing should be dried before wearing. Permethrin-treated clothing remains effective for many laun derings and has been shown repeatedly to reduce tick bites and reduce exposure to tickborne pathogens. Repellents should not be used on skin, clothing, or mosquito nets on which young chil dren may chew or suck. As soon as possible after potential tick expo sure, it is important to remove clothes as they may still harbor crawling ticks. When conducting tick checks, special attention should be given to the exposed regions of the body where ticks often attach, including the head, neck, and behind the ears on children. Ticks also may attach at areas of tight clothing (eg, sock line, belt line, axillae, groin). Curved forceps or tweezers are recommended; grasp close to the skin and gently pull straight out without twisting motions. Care must be taken not to break mouthparts (These often are cemented into the skin by the tick) as the tick is removed. The bite site should be washed with soap and water to reduce the risk of second ary skin infections. Daily inspection of pets and removal of ticks are indicated, as is the routine use of appropriate veterinary products to prevent ticks on pets. The most recent analyses of A-bomb survivor cancer in difficulties in distinguishing the fits of models with only one cidence and mortality data treatment for dogs eye discharge purchase doxycycline without a prescription. These models infection lining of lungs buy on line doxycycline, with dependence on both cer and nonmelanoma skin cancer exhibit exceptionally age at exposure and attained age infection control today order doxycycline mastercard, were chosen because of strong age-at-exposure dependencies that do not seem typi Copyright National Academy of Sciences antimicrobial growth promoters generic doxycycline 100mg visa. Further discussion of the rationale for choosing at exposure only for exposure ages under 30 years and are the Equation (12-2) model, including a detailed description constant for exposure ages over 30. That is, of analyses that were conducted by the committee, can be found in Annex 12B. The estimates of M and F are for a person exposed at sites, the number of incident cases is considerably larger than age 30 or older at an attained age of 60. However, and thyroid cancer were based on published analyses that models developed from incidence data were checked for included data on medically exposed persons as discussed consistency with mortality data. Models for breast and thyroid cancer are based on e instead of e*, although is still expressed per decade. Confdence intervals are based on standard errors of non-sex-specifc estimates with allowance for heterogeneity among studies. Although the common values of the param modifying factors and is thus more comparable to models eters and that have been used to quantify the modifying used for other sites. Although these models were developed for 1990; Schneider and others 1993), and an international estimating breast cancer incidence, they may also be used childhood cancer study (Tucker and others 1991). Both categorical and continu term for the main effect of time since exposure; note that ous treatments of age at exposure and time since exposure with this parameterization, there is no decrease with time have been used. This section de degree of curvature, which does not depend on sex, age at scribes the approach for addressing each of these issues, as exposure, or time since exposure; M and F represent the well as the methodology used to estimate lifetime risk. This model was found to fit the associated with some of these issues is discussed later in this data better than analogous models using e instead of e*, or chapter. For example, baseline risks but the youngest survivors (under age 20 at exposure). Al for cancers of the colon, lung, and female breast are higher though the extrapolation involved in estimating lifetime risks in the United States, whereas baseline risks for cancers of based on limited follow-up has been a major source of un the stomach and liver are much higher in Japan. Additional discussion of this issue is found in mittee based its estimates on absolute risk transport, where it Chapter 10. This choice was made because, as discussed in Chap considered of sufficient consequence to require explicit ac ter 10, there is somewhat greater support for relative risk counting in radiation protection regulations. This departure was made because of evidence that necessary to consider these differences in terms of the radio the interaction of radiation and smoking in A-bomb survi biological findings, the dosimetric and microdosimetric pa vors is additive (Pierce and others 2003). Although it is likely rameters of radiation quality, and the radioepidemiologic that the correct transport model varies by cancer site, for evidence. Because populations are higher than those at which the energy of the of the small number of deaths in the early period among radiation (based on biophysical considerations) would be those who were unexposed, it might be thought that the un expected to be important. However, it may be desirable to increase risk estimates in this report by a factor of 2 or 3 for the Relative Effectiveness of X-Rays and Rays purpose of estimating risks from low-dose X-ray exposure. Risk estimates in this report have been developed prima rily from data on A-bomb survivors and are thus directly Relative Effectiveness of Internal Exposure relevant to exposure from high-energy photons. For example, internal exposure to 131I, strontium, principal difference between the action of these different and cesium may occur from atmospheric fallout from nuclear types of radiation, because they all work through fast elec weapons testing. Epidemiologic studies involving these ex trons that either are incident on the body or are released posures are reviewed in Chapter 9. To date, these studies are not adequate to quan kiloelectronvolts per micrometer. These rates were available for each 5 the risk of untimely death by Vaeth and Pierce (1990). M I take account of persons dying of radiation-induced disease, Leukemia merits special comment. This difference may be riving incidence and mortality estimates based on relative important for estimating risks at higher doses (1+ Sv), but and absolute risk transport is the same for leukemia as for not at the low doses of interest for this report. In all cases, S(a)/S(e) is the probability of surviving to age a conditional the U. Models for leukemia differ from those for solid cancers the quantities S(a) were obtained from a 1999 unabridged in that risk is expressed as a function of age at exposure (e) life table for the U. That is, for a = e + 2 to e + 5, for cancer incidence, and M(D, e, a) = M(D, e, e + 5). That is, once a person was diagnosed with can cancer risks are obtained as the sum of site-specific risks, the cer (baseline or radiation induced), that person was removed uncertainty in these estimates was evaluated using models from the population at risk. Population tion (12-4) were weighted by the fraction of the population in the age group based on the U. Estimates exposure are for a person at birth, with allowance for attri of the numbers of excess cancers or deaths due to cancer in a tion of the population with age. In addition, esti estimates for chronic occupational exposure are for a person mates for all solid cancers and for leukemia are presented for who enters the workforce at age 18 and continues to be ex three specific exposure ages (10, 30, and 50 years), for a posed to age 65, again with allowance for attrition of the population that is exposed throughout life to 1 mGy per year, population with age. These estimates are obtained by weight and for a population that is exposed to 10 mGy per year from ing the age-at-exposure-specific estimates by the probability age 18 to 65.

For cancer mortality, the years of life lost per death absolute risk transport (also shown) and then reducing them are also of interest. The largest contribution to cancer incidence in males cal uncertainty alone is large (see Table 12-2). For cancers is from the residual category of other solid cancers fol of the stomach, liver, lung (females), prostate, and uterus, lowed by colon and lung cancer. These three categories are estimates based on relative and absolute risk differ by a fac also the most important contributors to cancer mortality. For sites other than lung, breast, and thyroid, relative risk transport was given a weight of 0. Sampling uncertainty in the parameters that quantify the modifying effects of age at exposure and attained age is not included except for the all solid cancer model. These estimates are generally about 20% higher greater than those for solid cancers. In each case, these were ob transport models as with most site-specific solid cancers, and tained as the sum of the site-specific estimates. Additional the subjective confidence intervals include transport uncer detail is given in Annex 12D.

The site-specific estimates were obtained as a weighted average (on a logarithmic scale) of estimates based on relative and absolute risk transport. Models for breast and thyroid cancer were based on data that included Caucasian subjects. Sampling uncertainty includes uncertainty in both the linear and the quadratic terms of the dose-response.

Similarly antimicrobial zinc gel buy doxycycline 100mg on line, Kaplan and colleagues (2006) did not compare tamsulosin to tolterodine bacterial infection in stomach cheap doxycycline 200mg with mastercard. The general applicability of withdrawal therapy noted here and elsewhere has not been determined thus the clinician is warned to consider this strategy as experimental antibiotics for acne pros and cons cheap doxycycline 200 mg free shipping. Another study also reported a more favorable change in QoL for 61 tamsulosin (P<0 virus 0f2490 buy doxycycline on line. Between weeks 26 and 52, however, there were no significant differences between the groups. Sexual function, as measured with a questionnaire that was not reported as validated, was not 62 significantly different between the two drugs. Predictors of Efficacy and Effectiveness Included trials did not generally examine the predictors of efficacy or adverse events. A post hoc analysis of a trial comparing tamsulosin and finasteride demonstrated that the greater improvements in Qmax with tamsulosin compared with finasteride at weeks one, six and 18, was significant for patients 62 with prostate volume less than 50 mL, but was not significant for larger glands. There was no significant differential effect after 18 weeks between the two drugs with large or small glands. Rates of total withdrawals from studies were variable; for 59 61 the 12-week trials rates ranged from 5% to 29%. In the latter study, both tamsulosin and finasteride groups lost approximately the same percentage of subjects, the majority due to failure to return for follow-up. In addition, in this trial, there were more treatment-emergent adverse events with finasteride (2. This finding contrasts markedly with another trial where rates 61 for tamsulosin were approximately 4%. Dizziness was commonly reported, with higher rates in the tamsulosin group compared with 63 59 placebo in one trial, similar rates in a second trial, while a third trial reported higher rates in the 72 placebo group. Hofner and colleagues (1999) examined sexual function with tamsulosin and alfuzosin in a meta-analysis of two 67 placebo-controlled trials of tamsulosin and a head-to-head trial of tamsulosin compared with alfuzosin. In a study with five-year follow-up, Palacio and colleagues (2004) reported a total of 114 nonserious adverse reactions during the first year; only 3. Adverse reactions were not defined and it was unclear if any withdrawals were due to adverse events. Study participants therefore had a variety of comorbid conditions: hypertension 18. In a much smaller cohort, 88% of subjects had a positive medical history, including 35% with 70 cardiovascular disease. Using prescription monitoring data, Mann and colleagues(2000) reported 74 adverse events for men issued a tamsulosin prescription. General practitioners also reported adverse events; the most common events were dizziness, nausea, and palpitations. Terazosin Terazosin is an 1-selective antagonist with a relatively long half-life that allows for once-daily dosing. Depending on response to therapy and tolerability, the dosage may be increased to 10 mg/day. Rates of adverse events were low, and dizziness occurred more frequently with terazosin (13%) than with finasteride (3%). The incidence of blood pressure-related adverse events with terazosin was similar between men on no antihypertensive treatment (13. Of those, all but 38 reported one or more episodes of nocturia, so that 1,040 men were included in this secondary analysis. Combination therapy also reduced nocturia episodes compared with 75 finasteride (p=0. Operative complications in some cases included posterior capsule rupture with vitreous loss and postoperative intraocular pressure spikes, though visual acuity outcomes appeared to be preserved. The study had insufficient power to determine whether discontinuation of tamsulosin reduced the risk of these complications, and no separate estimate of the risk was provided 89 for other alpha blockers, including alfuzosin. Therefore, the Panel believed that these new findings were supportive of their original conclusions. Summary Alpha-blockers produce significant symptom improvement compared to placebo that the average patient will appreciate as a moderate improvement from baseline. The minor differences in efficacy noted between the different alpha blockers are not statistically (when tested) or clinically significant. This presents a cost-effectiveness problem for tamsulosin (which is not yet available generically) because the 0. As this problem was not noted in the 2003 Guideline, it was the opinion of the Panel to include this comment in current guideline results. It was the opinion of the Panel that there is insufficient information to gauge the utility of alpha-blocker withdrawal therapy among men initially treated with combination therapy. Rates for specific adverse events were low and similar between treatment and placebo groups. Dizziness was the most common adverse event, with rates reported between 2% and 14% with alpha blockers and somewhat lower rates with placebo. Sexual function was reported sporadically in the studies reviewed with no significant difference between treatment groups. In general, although doxazosin and terazosin require dose titration and blood pressure monitoring, they are inexpensive, can be taken once daily, appear equally effective to tamsulosin and alfuzosin, and have generally similar side effect profiles. In the expert opinion of the Panel, the caveat remains that alpha blocker monotherapy is not considered optimal therapy for hypertension. While there are several medical and surgical ways to reduce the influence of androgenic steroids on the growth of the prostate. For reference, detailed evidence tables reviewing the studies evaluated by the Panel per the below are provided in Appendix A8. The majority of studies with finasteride were published before the 2003 Guideline and since then the molecule has lost patent protection. Only a small number of subsets or post hoc analyses and open-label extension studies have been reported since the 2003 Guideline was published. The primary publication by McConnell and colleagues was published in 1998, 95 thus was included in the prior report. Numerically improvements of 97, 98 three to four points had been reported and were maintained for six to 10 years of follow up. Mean interference domain score and daily activity questions were also improved more with finasteride than placebo (p<0. Rates of adverse events did not appear to relate to age, and there was no significant difference in cardiovascular events between finasteride and placebo treatment in either age cohort. Urodynamic parameter and Prostate Volume Measures Previous analyses of randomized, placebo-controlled trials had shown a sustained improvement in peak flow rates superior to placebo. Previous analyses of randomized, placebo-controlled trials had shown a reduction in prostate volume by about 15-25% which is achieved at 6 months and sustained over time. Thereafter the rates are similar suggesting that age-related deterioration in sexual and ejaculatory function is responsible rather than direct drug effects. Study discontinuation due to sexual adverse events occurred in 4% of finasteride patients and 2% with placebo. The incidence of prostate cancer was 3% with both continuous finasteride and men switched from placebo to finasteride. The most common drug-related adverse effects were sexual, including ejaculation disorders (3. One clinical center participating in this open-label extension study published data on their 43 study 107 participants at up to 10 years of follow-up.

Establish criteria for what constitutes a case Establish clear criteria to increase the accuracy of identifying a case: Criteria include person antibiotics for acne and eczema order doxycycline on line, place, and time (that is, who is at risk, where the event occurs, and when it occurs). The use of existing data sets reduces the expenditure of resources needed for surveillance. Ethical infringements in the surveillance process may contribute to harm and reduce the meaning and value of the data. Analyze data systematically to provide meaningful information for making decisions. In general, analyses include such elements as: An assessment of the crude number of cases (that is, the number of actual cases) and rates (the number of cases per a given denominator, such as 100 persons, or 10,000 or 100,000) A description of the population in which the condition occurs. Effectively interpret and disseminate data Interpret and disseminate data so decision-makers at all levels readily identify and understand the implications. Target users and communicate in a timely way: Develop dissemination plans that fit intended data users. Evaluate impact of the surveillance system Evaluating the surveillance system helps refine and improve the system for future use. Example Nurses in Ontario, Canada staffed a telephone health helpline to recruit and monitor participants with influenza-like symptoms (McGolrick et al. Consider whether surveillance is appropriate A telephone health helpline combined with nasal self-swabbing is a surveillance strat egy for early detection of influenza viruses. Clients do not have to go to a clinic for data collection; they receive a self-swabbing package and return it by mail. Acquire necessary knowledge of the problem Influenza viruses circulate worldwide and affect people of all ages causing significant morbidity and mortality annually (McGolrick et al. Influenza is transmit ted through respiratory droplets released into the air from coughing, sneezing, or talking, which are then inhaled or ingested. Influenza viruses can also spread indi rectly through contaminated hands or surfaces. Symptoms include sudden onset of high fever, runny nose, cough, headache, exhaustion, malaise, and inflammation of the upper respiratory tract. Many people who are infected experience mild symp toms, but severe infection can lead to death. Establish criteria for what constitutes a case Callers to the telephone health helpline are recruited to receive a self-swabbing packet if: 1) they meet the categories of referral or self-care, and 2) they are at least 2 years old and experiencing one or more symptoms (fever, cough, runny nose, or sore throat). Collect data from multiple sources Over one year, 87 specimens out of 664 test positive for influenza. Maintain ethical standards Although effective as a surveillance strategy, a delay in receiving a test result could lead to a delay in treatment. Providing education about self-care and when to seek medical help can reduce potential harm. Self-swabbing through the telephone health helpline provides a potential benefit by reducing visits to clinics and emergency departments, which may reduce viral trans mission in the community. Analyze data Two datasets [are] used for the self-swabbing study, one with the raw number of cases by week and another with an adjusted number of cases by week accounting for the increase in the number of nurses. Effectively interpret and disseminate data the implementation of a self-swabbing surveillance system provides an opportunity for public health authorities to generate diagnostic information that can be relayed to physicians. Further, this diagnostic information will aid in the practice of antimicrobial stewardship, which is an ongoing issue especially as it pertains to the inappropriate prescription of antimicrobials for the treatment of viral infections. Evaluate the impact of the surveillance system Based on comparisons with other influenza virus surveillance systems, telephone health helpline self-swabbing surveillance has significant potential as an adjunct tool for the surveillance of influenza viruses in Ontario (McGolrick et al. Types of surveillance Surveillance systems are passive, active, sentinel, or special. Criteria for surveillance Criteria for identifying high-priority health events for surveillance include: Frequency of event: Incidence, prevalence, mortality Severity of event: Case fatality ratio, hospitalization rate, disability rate, years of potential life years lost Cost Preventability Communicability Public interest Level 5 source: Lee et al. Characteristics of surveillance Characteristics of effective surveillance: Acceptability Sensitivity Flexibility Simplicity Positive predictive value Stability (proportion of true cases) Timeliness Quality Validity (measuring what is Representativeness supposed to be measured) Level 5 source: Centers for Disease Control and Prevention, 2012 5. Surveillance in conjunction with other systems Surveillance is most effective when done in conjunction with other systems in the community. Surveillance examples from the literature There are many examples of public health surveillance systems in the literature and their use to identify public health interventions: the District of Columbia Department of Health Environmental Public Health Tracking Network used climate change and health data to assess vulnerabilities and disease burden associated with heat, air quality, and hospitalizations for asthma and acute myocardial infarction. Web-based surveillance advantages and disadvantages Emerging web-based surveillance systems have advantages and disadvantages: They are intuitive, adaptable, low-cost, and operate in real time. Using surveillance for influenza Influenza surveillance using telephone triage and electronic syndromic surveillance (near real-time data collection) in the Department of Veterans Affairs correlated strongly with Centers for Disease Control and Prevention data for weekly influenza hospitalizations, influenza tests performed, and positive influenza tests. Developments in surveillance Developments in population health surveillance initiatives include: Mental health measures are now included in national level surveillance surveys. Collecting data on resilience, coping skills, protective factors, cultural factors, and positive mental health aspects provides information for disease prevention and mental health promotion strategies. Challenges to surveillance of mental health include variable and non-specific measures, differences in time periods, variability in including substance abuse, and different methods of data collection. In addition to monitoring population health status and outcomes, other uses include conducting community health assessments, iden tifying population health disparities, and designing public health interventions, programs, and policies. Challenges included incomplete population cov erage, inability to link data systems, and variations in data quality. Increasing data accuracy and usefulness with surveys Strategies for increasing the accuracy and usefulness of data on health behaviors ob tained from surveys: Conduct pilot surveys before full implementation. Level 5 source: Mokdad & Remington, 2010 Wheel notes Epidemiology Public health nurses use the science of epidemiology to conduct surveillance. Epidemiology is: [The] study of the occurrence and distribution of health-related states or events in specified populations, including the study of the determinants influencing such states, and the application of this knowledge to control the health problems (Porta, 2008, p. Epide miology as a systematic process guides the search for contributing factors, data col lection, and monitoring of health and illness events (Frayham & Anderko, 2009; Schoon, Porta, & Schaffer, 2018). Electronic health rec ords needs to be compatible with other systems (across health departments and other health systems) in order to aggregate data. The Public Health Data Standards Consortium (2019) established recommendations for collecting data through elec tronic health records. Resources the Centers for Disease Control and Prevention established the Surveillance Resource Center, which provides access to information and tools for conducting surveillance: interactive database systems; methods; legal, ethical, and policy issues; and tools and templates.
