Objectives: The Centers for Disease Control and Prevention launched the Temporary Epidemiology Field Assignee (TEFA) Program to help state and local jurisdictions respond to the risk of Ebola virus importation during the 2014-2016 Ebola Outbreak in West Africa. We describe steps taken to launch the 2-year program, its outcomes and lessons learned. Methods: State and local health departments submitted proposals for a TEFA to strengthen local capacity in four key public health preparedness areas: 1) epidemiology and surveillance, 2) health systems preparedness, 3) health communications, and 4) incident management. TEFAs and jurisdictions were selected through a competitive process. Descriptions of TEFA activities in their quarterly reports were reviewed to select illustrative examples for each preparedness area. Results: Eleven TEFAs began in the fall of 2015, assigned to 7 states, 2 cities, 1 county and the District of Columbia. TEFAs strengthened epidemiologic capacity, investigating routine and major outbreaks in addition to implementing event-based and syndromic surveillance systems. They supported improvements in health communications, strengthened healthcare coalitions, and enhanced collaboration between local epidemiology and emergency preparedness units. Several TEFAs deployed to United States territories for the 2016 Zika Outbreak response. Conclusion: TEFAs made important contributions to their jurisdictions' preparedness. We believe the TEFA model can be a significant component of a national strategy for surging state and local capacity in future high-consequence events.

The International Health Regulations (IHR), an international law under the auspices of the World Health Organization (WHO), mandates that countries notify other countries of "travelers under public health observation." Between November 10, 2014, and July 12, 2015, the US Centers for Disease Control and Prevention (CDC) made 2,374 notifications to the National IHR Focal Points in 114 foreign countries of travelers who were monitored by US health departments because they had been to an Ebola-affected country in West Africa. Given that countries have preidentified focal points as points of contacts for sharing of public health information, notifications could be made by CDC to a trusted public health recipient in another country within 24 hours of receipt of the traveler's information from a US health department. The majority of US health departments used this process, offered by CDC, to notify other countries of travelers intending to leave the United States while being monitored in their jurisdiction.

The first patients with laboratory-confirmed cases of Zika virus disease in American Samoa had symptom onset in January 2016. In response, the American Samoa Department of Health (ASDoH) implemented mosquito control measures, strategies to protect pregnant women, syndromic surveillance based on electronic health record (EHR) reports, Zika virus testing of persons with one or more signs or symptoms of Zika virus disease (fever, rash, arthralgia, or conjunctivitis), and routine testing of all asymptomatic pregnant women in accordance with CDC guidance. All collected blood and urine specimens were shipped to the Hawaii Department of Health Laboratory for Zika virus testing and to CDC for confirmatory testing. Early in the response, collection and testing of specimens from pregnant women was prioritized over the collection from symptomatic nonpregnant patients because of limited testing and shipping capacity. The weekly numbers of suspected Zika virus disease cases declined from an average of six per week in January-February 2016 to one per week in May 2016. By August, the EHR-based syndromic surveillance indicated a return to pre-outbreak levels. The last Zika virus disease case detected by real-time, reverse transcription-polymerase chain reaction (rRT-PCR) occurred in a patient who had symptom onset on June 19, 2016. In August 2016, ASDoH requested CDC support in assessing whether local transmission had been reduced or interrupted and in proposing a timeline for discontinuation of routine testing of asymptomatic pregnant women. An end date (October 15, 2016) was determined for active mosquito-borne transmission of Zika virus and a timeline was developed for discontinuation of routine screening of asymptomatic pregnant women in American Samoa (conception after December 10, 2016, with permissive testing for asymptomatic women who conceive through April 15, 2017).

The U.S. Department of Health and Human Services (HHS), CDC, other U.S. government agencies, the World Health Organization (WHO), and international partners are taking multiple steps to respond to the current Ebola virus disease (Ebola) outbreak in West Africa to reduce its toll there and to reduce the chances of international spread. At the same time, CDC and HHS are working to ensure that persons who have a risk factor for exposure to Ebola and who develop symptoms while in the United States are rapidly identified and isolated, and safely receive treatment. HHS and CDC have actively worked with state and local public health authorities and other partners to accelerate health care preparedness to care for persons under investigation (PUI) for Ebola or with confirmed Ebola. This report describes some of these efforts and their impact.

OBJECTIVE: During 2009-2011, Pike County, Kentucky, experienced a series of severe weather events that resulted in property damage, insufficient potable water, and need for temporary shelters. A Community Assessment for Public Health Emergency Response (CASPER) survey was implemented for future planning. CASPER assesses household health status, preparedness level, and anticipated demand for shelters. METHODS: We used a 2-stage cluster sampling design to randomly select 210 representative households for in-person interviews. We estimated the proportion of households with children aged 2 years or younger; adults aged 65 years or older; and residents with chronic health conditions, visual impairments, physical limitations, and supplemental oxygen requirements. RESULTS: Of all households surveyed, 8% included children aged 2 years or younger, and 27% included adults aged 65 years or older. The most common chronic health conditions were heart disease (51%), diabetes (28%), lung disease (23%), and asthma (21%). Visual impairments were reported in 29% of households, physical limitations in 24%, and supplemental oxygen use in 12%. CONCLUSIONS: Pike County residents should be encouraged to maintain an adequate supply of medications and copies of their prescriptions. Emergency response plans should include transportation for persons with physical limitations; and shelter plans should include sufficient medically trained staff and adequate supplies of infant formula, pharmaceuticals, and supplemental oxygen.

OBJECTIVE: Brucellosis is uncommon in the United States; however, its circulation among wildlife and domestic cattle has been ongoing in Wyoming. To assess the public health threat of brucellosis circulation among animals, a seroprevalence study was undertaken among workers in professions considered to be at the highest risk for infection. METHODS: A seroprevalence study was undertaken targeting individuals in at-risk professions in the affected area of the state. RESULTS: Seroprevalence among study participants was 14.4%. Veterinarians were the main professional group that demonstrated a statistically significant association with measurable anti-Brucella antibodies. Vaccinating animals with Brucella vaccines was associated with seropositivity. CONCLUSION: The risk to the general public's health from the circulation of Brucella among wildlife and cattle can be attributed primarily to a limited subpopulation at high risk rather than a generally elevated risk.

Recent routine screening revealed multiple cases of unexplained lead poisoning among children of Burmese refugees living in Fort Wayne, Indiana. A cross-sectional study was conducted to determine (a) the prevalence of elevated blood lead levels (BLLs) among Burmese children and (b) potential sources of lead exposure. A case was defined as an elevated venous BLL (≥10 mug/dL); prevalence was compared with all Indiana children screened during 2008. Environmental and product samples were tested for lead. In all, 14 of 197 (7.1%) children had elevated BLLs (prevalence ratio: 10.7) that ranged from 10.2 to 29.0 mug/dL. Six cases were newly identified; 4 were among US-born children. Laboratory testing identified a traditional ethnic digestive remedy, Daw Tway, containing a median 520 ppm lead. A multilevel linear regression model identified daily use of thanakha, an ethnic cosmetic, and Daw Tway use were related to elevated BLLs (P < .05). Routine monitoring of BLLs among this population should remain a priority.

INTRODUCTION: After a train derailment released chlorine gas in Graniteville, South Carolina, in 2005, a multiagency team performed an epidemiologic assessment of chlorine exposure and resulting health effects. Five months later, participants were resurveyed to determine their health status and needs and to assist in planning additional interventions in the community. METHODS: Questionnaires were mailed to 279 patients interviewed in the initial assessment; follow-up telephone calls were made to nonresponders. The questionnaire included questions regarding duration of symptoms experienced after exposure and a posttraumatic stress disorder (PTSD) assessment tool. RESULTS: Ninety-four questionnaires were returned. Seventy-six persons reported chronic symptoms related to the chlorine exposure, 47 were still under a doctor's care, and 49 were still taking medication for chlorine-related problems. Agreement was poor between the first and second questionnaires regarding symptoms experienced after exposure to the chlorine (kappa = 0.30). Forty-four respondents screened positive for PTSD. PTSD was associated with post-exposure hospitalization for three or more nights [relative risk (RR) = 1.7; 95% confidence interval (CI) = 1.1-2.6] and chronic symptoms (RR = 9.1; 95% CI = 1.3-61.2), but not with a moderate-to-extreme level of chlorine exposure (RR = 1.2; 95% CI = 0.8-1.8). CONCLUSIONS: Some victims of this chlorine exposure event continued to experience physical symptoms and continued to require medical care 5 months later. Chronic mental health symptoms were prevalent, especially among persons experiencing the most severe or persistent physical health effects. Patients should be interviewed as soon as possible after an incident because recall of acute symptoms experienced can diminish within months.

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has rapidly emerged in the USA as a cause of severe infections in previously healthy persons without traditional risk factors. We describe the epidemiology of severe CA-MRSA disease in the state of Georgia, USA and analyse the risk of death associated with three different clinical syndromes of CA-MRSA disease - pneumonia, invasive disease, and skin and soft-tissue infections (SSTIs). A total of 1670 cases of severe CA-MRSA disease were reported during 2005-2007. The case-fatality rate was 3.4%; sex and race of fatal and non-fatal cases did not differ significantly. While CA-MRSA pneumonia and invasive disease were less common than SSTIs, they were about 15 times more likely to result in death [risk ratio 16.69, 95% confidence interval (CI) 10.28-27.07 and 13.98, 95% CI 7.74-25.27, respectively]. When controlling for age and the presence of other clinical syndromes the odds of death in patients manifesting specific severe CA-MRSA syndromes was highest in those with pneumonia (odds ratio 11.34). Possible risk factors for severe CA-MRSA SSTI and pneumonia included the draining of lesions without medical assistance and an antecedent influenza-like illness.
