Perceptions of opioid and other illicit drug exposure reported among first responders in the southeast, 2017 to 2018.

BACKGROUND: Opioid use has risen dramatically in recent years, and its illegal use puts first responders at risk when intervening in overdoses. Synthetic opioids, like fentanyl with a potency 50 to 100 times greater than morphine, pose a great risk and accidental exposure via ingestion, inhalation, mucosal, or percutaneous routes, can potentially lead to fatal outcomes. Anecdotal media accounts in early 2017 of accidental occupational opioid exposure among first responders generated a national concern. METHODS: To identify first responders' recollections, beliefs, and concerns about possible occupational exposure to opioids and other drugs, researchers in Kentucky, Virginia, Mississippi, and Georgia administered an emailed, anonymous convenience sample survey. RESULTS: A total of 5955 surveys were analyzed with 15% of respondents reporting they believed they had been exposed to opioids, and of those, less than 1% reported experiencing health effects from perceived exposure. Over half (51%) of respondents reported being "very or somewhat concerned" about developing health effects from exposure to opioids. Half of respondents reported being unaware of Centers for Disease Control and Prevention (CDC)/National Institutes for Occupational Safety and Health (NIOSH) guidelines for preventing occupational-related opioid exposures. CONCLUSIONS: Only a small fraction of first responders believed they had experienced symptoms related to opioid exposure in overdose response calls, but half were concerned about potential exposures and half were unaware of the educational guidance on prevention available. The high level of concern regarding potential exposure warrants the need for the development and or enhancement of targeted educational training interventions and further dissemination of pre-existing training interventions to ensure first responders have the knowledge and understanding of occupational opioid exposures and minimize stress associated with the potential rare exposures.

Use of Real-Time PCR for Chlamydia psittaci Detection in Human Specimens During an Outbreak of Psittacosis - Georgia and Virginia, 2018.

Psittacosis is typically a mild febrile respiratory illness caused by infection with the bacterium Chlamydia psittaci and usually transmitted to humans by infected birds (1). On average, 11 psittacosis cases per year were reported in the United States during 2000-2017. During August-October 2018, the largest U.S. psittacosis outbreak in 30 years (82 cases identified*) occurred in two poultry slaughter plants, one each in Virginia and Georgia, that shared source farms (2). CDC used C. psittaci real-time polymerase chain reaction (PCR) to test 54 human specimens from this outbreak. This was the largest number of human specimens from a single outbreak ever tested for C. psittaci using real-time PCR, which is faster and more sensitive than commercially available serologic tests. This represented a rare opportunity to assess the utility of multiple specimen types for real-time PCR detection of C. psittaci. C. psittaci was detected more frequently in lower respiratory specimens (59% [10 of 17]) and stool (four of five) than in upper respiratory specimens (7% [two of 28]). Among six patients with sputum and nasopharyngeal swabs tested, C. psittaci was detected only in sputum in five patients. Cycle threshold (Ct) values suggested bacterial load was higher in lower respiratory specimens than in nasopharyngeal swabs. These findings support prioritizing lower respiratory specimens for real-time PCR detection of C. psittaci. Stool specimens might also have utility for diagnosis of psittacosis.

Salmonellosis Outbreak After a Large-Scale Food Event in Virginia, 2017.

OBJECTIVES: The Virginia Department of Health (VDH) identified an outbreak of Salmonella serotype Javiana infections in Virginia after a chili and chowder cook-off with 11 competitors and about 2500 attendees on September 30, 2017. The objectives of this study were to assess the extent of the outbreak and identify the most likely source of exposure. METHODS: To identify people with suspected Salmonella infection, VDH used press releases and social media posts to recruit event attendees to take an online survey about foods eaten at the cook-off and any gastrointestinal (GI) symptoms experienced. VDH defined a case as reported GI illness that occurred within 1 week after eating food from the cook-off. Confirmed cases required a clinical specimen culture positive for Salmonella. Probable cases reported diarrhea or related clinical symptoms. "Not ill" people did not report GI illness. Investigators calculated unadjusted relative risks of illness and performed stratified analysis to address potential confounding. Available food samples were tested for Salmonella. Environmental health specialists interviewed food handlers and inspected restaurants where 3 competitors had prepared food. RESULTS: Of 438 survey responses, 171 (39%) met the case definition. Of all chilies and chowders consumed, Chowder A was associated with the highest relative risk of illness (8.9; 95% CI, 5.7-13.7). A Chowder A sample tested positive for Salmonella serotype Javiana. The environmental investigation did not identify an original contamination source but did find deficiencies in maintaining safe cooking temperatures. CONCLUSIONS: Epidemiologic and laboratory findings indicated that Chowder A was the most likely cause of outbreak. Recommendations to prevent future outbreaks include preparation of all food on-site to ensure safe temperatures during food preparation and service.

COVID-19 in Correctional and Detention Facilities - United States, February-April 2020.

An estimated 2.1 million U.S. adults are housed within approximately 5,000 correctional and detention facilities† on any given day (1). Many facilities face significant challenges in controlling the spread of highly infectious pathogens such as SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19). Such challenges include crowded dormitories, shared lavatories, limited medical and isolation resources, daily entry and exit of staff members and visitors, continual introduction of newly incarcerated or detained persons, and transport of incarcerated or detained persons in multiperson vehicles for court-related, medical, or security reasons (2,3). During April 22-28, 2020, aggregate data on COVID-19 cases were reported to CDC by 37 of 54 state and territorial health department jurisdictions. Thirty-two (86%) jurisdictions reported at least one laboratory-confirmed case from a total of 420 correctional and detention facilities. Among these facilities, COVID-19 was diagnosed in 4,893 incarcerated or detained persons and 2,778 facility staff members, resulting in 88 deaths in incarcerated or detained persons and 15 deaths among staff members. Prompt identification of COVID-19 cases and consistent application of prevention measures, such as symptom screening and quarantine, are critical to protecting incarcerated and detained persons and staff members.

COVID-19 Among Workers in Meat and Poultry Processing Facilities - 19 States, April 2020.

Congregate work and residential locations are at increased risk for infectious disease transmission including respiratory illness outbreaks. SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is primarily spread person to person through respiratory droplets. Nationwide, the meat and poultry processing industry, an essential component of the U.S. food infrastructure, employs approximately 500,000 persons, many of whom work in proximity to other workers (1). Because of reports of initial cases of COVID-19, in some meat processing facilities, states were asked to provide aggregated data concerning the number of meat and poultry processing facilities affected by COVID-19 and the number of workers with COVID-19 in these facilities, including COVID-19-related deaths. Qualitative data gathered by CDC during on-site and remote assessments were analyzed and summarized. During April 9-27, aggregate data on COVID-19 cases among 115 meat or poultry processing facilities in 19 states were reported to CDC. Among these facilities, COVID-19 was diagnosed in 4,913 (approximately 3%) workers, and 20 COVID-19-related deaths were reported. Facility barriers to effective prevention and control of COVID-19 included difficulty distancing workers at least 6 feet (2 meters) from one another (2) and in implementing COVID-19-specific disinfection guidelines.* Among workers, socioeconomic challenges might contribute to working while feeling ill, particularly if there are management practices such as bonuses that incentivize attendance. Methods to decrease transmission within the facility include worker symptom screening programs, policies to discourage working while experiencing symptoms compatible with COVID-19, and social distancing by workers. Source control measures (e.g., the use of cloth face covers) as well as increased disinfection of high-touch surfaces are also important means of preventing SARS-CoV-2 exposure. Mitigation efforts to reduce transmission in the community should also be considered. Many of these measures might also reduce asymptomatic and presymptomatic transmission (3). Implementation of these public health strategies will help protect workers from COVID-19 in this industry and assist in preserving the critical meat and poultry production infrastructure (4).

Postnatally Acquired Zika Virus Disease Among Children, United States, 2016-2017.

BACKGROUND: The clinical findings among children with postnatally acquired Zika virus disease are not well characterized. We describe and compare clinical signs and symptoms for children aged <18 years. METHODS: Zika virus disease cases were included if they met the national surveillance case definition, had illness onset in 2016 or 2017, resided in a participating state, and were reported to the Centers for Disease Control and Prevention. Pediatric cases were aged <18 years; congenital and perinatal infections were excluded. Pediatric cases were matched to adult cases (18‒49 years). Clinical information was compared between younger and older pediatric cases and between children and adults. RESULTS: A total of 141 pediatric Zika virus disease cases were identified; none experienced neurologic disease. Overall, 28 (20%) were treated in an emergency department, 1 (<1%) was hospitalized; none died. Of the 4 primary clinical signs and symptoms associated with Zika virus disease, 133 (94%) children had rash, 104 (74%) fever, 67 (48%) arthralgia, and 51 (36%) conjunctivitis. Fever, arthralgia, and myalgia were more common in older children (12‒17 years) than younger children (1‒11 years). Arthralgia, arthritis, edema, and myalgia were more common in adults compared to children. CONCLUSIONS: This report supports previous findings that Zika virus disease is generally mild in children. The most common symptoms are similar to other childhood infections, and clinical findings and outcomes are similar to those in adults. Healthcare providers should consider a diagnosis of Zika virus infection in children with fever, rash, arthralgia, or conjunctivitis, who reside in or have traveled to an area where Zika virus transmission is occurring.

Psittacosis Outbreak among Workers at Chicken Slaughter Plants, Virginia and Georgia, USA, 2018.

During August-October, 2018, an outbreak of severe respiratory illness was reported among poultry slaughter plant workers in Virginia and Georgia, USA. A multiorganizational team investigated the cause and extent of illness, determined that the illness was psittacosis, and evaluated and recommended controls for health hazards in the workplace to prevent additional cases.

Swine-origin influenza virus (SOIV) in Louisiana, 2009.

Since the new flu strain--named A(H1N1) or Swine Origin Influenza Virus (SOIV) to differentiate it from the seasonal H1N1--first emerged in Mexico and the United States in April, it has spread to 74 countries around the globe. The objectives of this article are to describe the initial stages of the epidemic in Louisiana and to draw some epidemiologic lessons for the future, which could be particularly useful if the pandemic continues during the winter season 2009-2010. Between April 22, 2009 (date when the first specimen was collected) to May 31, 2009, a six week period, there were 133 cases of SOIV infection detected in Louisiana. Cases were diagnosed in late April in several regions of the state, showing that when the first cases had been identified in Mexico and California, the infection was already widespread in Louisiana. The most affected age group was between the ages of five and 25.
