Translocation of an Anteater (Tamandua tetradactyla) Infected with Rabies from Virginia to Tennessee Resulting in Multiple Human Exposures, 2021.

On August 16, 2021, the Tennessee Department of Health (TDH) was notified of a positive rabies test result from a South American collared anteater (Tamandua tetradactyla) in Washington County, Tennessee. Tamanduas, or lesser anteaters, are a species of anteater in which rabies has not previously been reported. The animal was living at a Tennessee zoo and had been recently translocated from a zoo in Virginia. TDH conducted an investigation to confirm the rabies result, characterize the rabies variant, and ascertain an exposure risk assessment among persons who came into contact with the tamandua. Risk assessments for 22 persons were completed to determine the need for rabies postexposure prophylaxis (rPEP); rPEP was recommended for 13 persons, all of whom agreed to receive it. Using phylogenetic results of the virus isolated from the tamandua and knowledge of rabies epidemiology, public health officials determined that the animal was likely exposed to wild raccoons present at the Virginia zoo. This report describes expansion of the wide mammalian species diversity susceptible to rabies virus infection and summarizes the investigation, highlighting coordination among veterinary and human public health partners and the importance of preexposure rabies vaccination for animal handlers and exotic zoo animals.

Distance to Kidney Transplant Center and Access to Early Steps in the Kidney Transplantation Process in the Southeastern United States.

BACKGROUND AND OBJECTIVES: Access to kidney transplantation requires a referral to a transplant center for medical evaluation. Prior research suggests that the distance that a person must travel to reach a center might be a barrier to referral. We examined whether a shorter distance from patients' residence to a transplant center increased the likelihood of referral and initiating the transplant evaluation once referred. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Adults who began treatment for ESKD at any Georgia, North Carolina, or South Carolina dialysis facility from 1/1/2012 to 12/31/2015 were identified from the US Renal Data System. Referral (within 1 year of dialysis initiation) and evaluation initiation (within 6 months of referral) data were collected from all nine transplant centers located in that region. Distance was categorized as <15, 15-30, 31-60, 61-90, and >90 miles from the center of a patient's residential zip code to the nearest center. We used multilevel, multivariable-adjusted logistic regression to quantify the association between distance with referral and evaluation initiation. RESULTS: Among 27,250 adult patients on incident dialysis, 9582 (35%) were referred. Among those referred, 58% initiated evaluation. Although patients who lived farther from a center were less likely to be referred, distance was not statistically significantly related to transplant referral: adjusted odds ratios of 1.08 (95% confidence interval, 0.96 to 1.22), 1.07 (95% confidence interval, 0.95 to 1.22), 0.96 (95% confidence interval, 0.84 to 1.10), and 0.87 (95% confidence interval, 0.74 to 1.03) for 15-30, 31-60, 61-90, and >90 miles, respectively, compared with <15 miles (P trend =0.05). There was no statistically significant association of distance and evaluation initiation among referred patients: adjusted odds ratios of 1.14 (95% confidence interval, 0.97 to 1.33), 1.12 (95% confidence interval, 0.94 to 1.35), 1.04 (95% confidence interval, 0.87 to 1.25), and 0.89 (95% confidence interval, 0.72 to 1.11) for 15-30, 31-60, 61-90, and >90 miles, respectively, compared with <15 miles (P trend =0.70). CONCLUSIONS: Distance from residence to transplant center among patients undergoing long-term dialysis in the southeastern United States was not associated with increased likelihood of referral and initiating transplant center evaluation.

Foodborne Disease Outbreaks in the United States: A Historical Overview.

Understanding the epidemiology of foodborne disease outbreaks (FBDOs) is important for informing investigation, control, and prevention methods. We examined annual summary FBDO data in the United States from 1938 to 2015, to help understand the epidemiology of outbreaks over time. Due to changes in reporting procedures, before 1998, the mean number of annual outbreaks was 378, and after that, it was 1062. A mean of 42% had a known etiology during 1961-1998; since then the etiology has been identified in ∼65%, with a marked increase in the number of norovirus outbreaks. From 1967 to 1997, a mean of 41% of FBDOs occurred in restaurant settings, increasing to 60% in 1998-2015. Concurrently, the proportion of outbreaks occurring at a home decreased from 25% to 8%. The mean size of outbreaks has decreased over time, and the number of multistate outbreaks has increased. Many social, economic, environmental, technological, and regulatory changes have dramatically affected the epidemiology of foodborne disease over time.
