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.

Francisella tularensis Transmission by Solid Organ Transplantation, 20171.

In July 2017, fever and sepsis developed in 3 recipients of solid organs (1 heart and 2 kidneys) from a common donor in the United States; 1 of the kidney recipients died. Tularemia was suspected only after blood cultures from the surviving kidney recipient grew Francisella species. The organ donor, a middle-aged man from the southwestern United States, had been hospitalized for acute alcohol withdrawal syndrome, pneumonia, and multiorgan failure. F. tularensis subsp. tularensis (clade A2) was cultured from archived spleen tissue from the donor and blood from both kidney recipients. Whole-genome multilocus sequence typing indicated that the isolated strains were indistinguishable. The heart recipient remained seronegative with negative blood cultures but had been receiving antimicrobial drugs for a medical device infection before transplant. Two lagomorph carcasses collected near the donor's residence were positive by PCR for F. tularensis subsp. tularensis (clade A2). This investigation documents F. tularensis transmission by solid organ transplantation.

Anaplasmosis-Related Fatality in Vermont: A Case Report.

Human granulocytic anaplasmosis is an acute febrile tick-borne illness caused by the bacterium Anaplasma phagocytophilum. An anaplasmosis-related fatality in a Vermont resident with multiple comorbidities is described. Clinicians should be aware of the risk factors for severe outcomes of this emerging disease and promptly treat when suspected.

Potential quantitative effect of a laboratory-based approach to Lyme disease surveillance in high-incidence states.

Historically, public health surveillance for Lyme disease has required clinical follow-up on positive laboratory reports for the purpose of case classification. In areas with sustained high incidence of the disease, this resource-intensive activity yields a limited benefit to public health practice. A range of burden-reducing strategies have been implemented in many states, creating inconsistencies that limit the ability to decipher trends. Laboratory-based surveillance, or surveillance based solely on positive laboratory reports without follow-up for clinical information on positive laboratory reports, emerged as a feasible alternative to improve standardization in already high-incidence areas. To inform expectations of a laboratory-based surveillance model, we conducted a retrospective analysis of Lyme disease data collected during 2012-2018 from 10 high-incidence states. The number of individuals with laboratory evidence of infection ranged from 1302 to 20,994 per state and year. On average, 55% of those were ultimately classified as confirmed or probable cases (range: 29%-86%). Among all individuals with positive laboratory evidence, 18% (range: 2%-37%) were determined to be 'not a case' upon investigation and 23% (range: 2%-52%) were classified as suspect cases due to lack of associated clinical information and thus were not reported to the Centers for Disease Control and Prevention (CDC). The number of reported cases under a laboratory-based approach to surveillance in high-incidence states using recommended two-tier testing algorithms is likely to be, on average, 1.2 times higher (range: 0.6-1.8 times) than what was reported to CDC during 2012-2018. A laboratory-based surveillance approach for high-incidence states will improve standardization and reduce burden on public health systems, allowing public health resources to focus on prevention messaging, exploration of novel prevention strategies and alternative data sources to yield information on the epidemiology of Lyme disease.

Francisella tularensis infection in dogs: 88 cases (2014-2016).

OBJECTIVE: To characterize the epidemiology, clinical signs, and treatment of dogs with Francisella tularensis infection in New Mexico. ANIMALS: 87 dogs in which 88 cases of tularemia (1 dog had 2 distinct cases) were confirmed by the New Mexico Department of Health Scientific Laboratory Division from 2014 through 2016 and for which medical records were available. PROCEDURES: Dogs were confirmed to have tularemia if they had a 4-fold or greater increase in anti-F tularensis antibody titer between acute and convalescent serum samples or F tularensis had been isolated from a clinical or necropsy specimen. Epidemiological, clinical, and treatment information were collected from the dogs' medical records and summarized. RESULTS: All 88 cases of tularemia were confirmed by paired serologic titers; the first (acute) serologic test result was negative for 84 (95%) cases. The most common reported exposure to F tularensis was wild rodent or rabbit contact (53/88 [60%]). Dogs had a median number of 3 clinical signs at initial evaluation; lethargy (81/88 [92%]), pyrexia (80/88 [91%]), anorexia (67/88 [76%]), and lymphadenopathy (18/88 [20%]) were most common. For 32 (36%) cases, the dog was hospitalized; all hospitalized dogs survived. CONCLUSIONS AND CLINICAL RELEVANCE: Dogs with F tularensis infection often had nonspecific clinical signs and developed moderate to severe illness, sometimes requiring hospitalization. Veterinarians examining dogs from tularemia-enzootic areas should be aware of the epidemiology and clinical signs of tularemia, inquire about potential exposures, and discuss prevention methods with owners, including reducing exposure to reservoir hosts and promptly seeking care for ill animals.

Human tularaemia associated with exposure to domestic dogs-United States, 2006-2016.

Dogs have been implicated in the zoonotic transmission of numerous pathogens. Whereas cats are known to transmit Francisella tularensis to humans via bite and other routes, the role of dogs in facilitating infection is much less understood. We reviewed tularaemia case investigation records collected through national surveillance during 2006-2016 to summarize those with dog involvement, characterize the nature of dog-related exposure and describe associated clinical characteristics. Among 1,814 human tularaemia cases, 735 (41%) supplemental case investigation records were available for review; and of those, 24 (3.3%) were classified as dog-related. Median age of patients was 51 years (range: 1-82); 54% were female. Two thirds (67%) of cases presented with ulceroglandular/glandular tularaemia; pneumonic (13%) and oropharyngeal (13%) illness occurred less frequently. Dog-related exposures were classified as follows: direct contact via bite, scratch or face snuggling/licking (n = 12; 50%); direct contact with dead animals retrieved by domestic dogs (n = 8; 33%); and contact with infected ticks acquired from domestic dogs (n = 4; 17%). Prevention of dog-related tularaemia necessitates enhanced tularaemia awareness and tick avoidance among pet owners, veterinarians, health care providers and the general public.

Tularemia (Francisella tularensis) in a Black-Tailed Prairie Dog (Cynomys ludovicianus) Colony.

Tularemia is a bacterial zoonosis caused by Francisella tularensis. We conducted a serosurvey of black-tailed prairie dogs (Cynomys ludovicianus) in Devils Tower National Monument, Wyoming, US, following an epizootic in voles ( Microtus spp.) due to F. tularensis. Only 1 of 44 (2%) sampled prairie dogs was seropositive for F. tularensis, providing evidence of survival and potentially limited spread among free-ranging prairie dogs.

Risk Factors for Clinician-Diagnosed Lyme Arthritis, Facial Palsy, Carditis, and Meningitis in Patients From High-Incidence States.

BACKGROUND: Clinical features of Lyme disease (LD) range from localized skin lesions to serious disseminated disease. Information on risk factors for Lyme arthritis, facial palsy, carditis, and meningitis is limited but could facilitate disease recognition and elucidate pathophysiology. METHODS: Patients from high-incidence states treated for LD during 2005-2014 were identified in a nationwide insurance claims database using the International Classification of Diseases, Ninth Revision code for LD (088.81), antibiotic treatment history, and clinically compatible codiagnosis codes for LD manifestations. RESULTS: Among 88022 unique patients diagnosed with LD, 5122 (5.8%) patients with 5333 codiagnoses were identified: 2440 (2.8%) arthritis, 1853 (2.1%) facial palsy, 534 (0.6%) carditis, and 506 (0.6%) meningitis. Patients with disseminated LD had lower median age (35 vs 42 years) and higher male proportion (61% vs 50%) than nondisseminated LD. Greatest differential risks included arthritis in males aged 10-14 years (odds ratio [OR], 3.5; 95% confidence interval [CI], 3.0-4.2), facial palsy (OR, 2.1; 95% CI, 1.6-2.7) and carditis (OR, 2.4; 95% CI, 1.6-3.6) in males aged 20-24 years, and meningitis in females aged 10-14 years (OR, 3.4; 95% CI, 2.1-5.5) compared to the 55-59 year referent age group. Males aged 15-29 years had the highest risk for complete heart block, a potentially fatal condition. CONCLUSIONS: The risk and manifestations of disseminated LD vary by age and sex. Provider education regarding at-risk populations and additional investigations into pathophysiology could enhance early case recognition and improve patient management.
