We conducted surveillance for carbapenem-resistant Enterobacterales (CRE) during 2016-2020 at 10 US sites and extended-spectrum β-lactamase--producing Enterobacterales (ESBL-E) during 2019-2020 at 6 US sites. Among 159 CRE cases in children (median age 5 years), CRE was isolated from urine for 131 (82.4%) and blood from 20 (12.6%). Annual CRE incidence rate (cases/ 100,000 population) was 0.47-0.87. Among 207 ESBLE cases in children (median age 6 years), ESBL-E was isolated from urine of 196 (94.7%) and blood of 8 (3.9%). Annual ESBL-E incidence rate was 26.5 in 2019 and 19.63 in 2020. CRE and ESBL-E rates were >2-fold higher among infants than other age groups. Most CRE and ESBL-E cases were healthcare-associated community-onset (68 [43.0%] for CRE vs. 40 [23.7%] for ESBL-E) or community-associated (43 [27.2%] for CRE vs. 109 [64.5%] for ESBL-E). Programs to detect, prevent, and treat multidrugresistant infections must include pediatric populations (particularly the youngest) and outpatient settings. [ABSTRACT FROM AUTHOR]

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.

We report an outbreak of severe acute respiratory syndrome coronavirus 2 involving 3 Malayan tigers (Panthera tigris jacksoni) at a zoo in Tennessee, USA. Investigation identified naturally occurring tiger-to-tiger transmission; genetic sequence change occurred with viral passage. We provide epidemiologic, environmental, and genomic sequencing data for animal and human infections. [ABSTRACT FROM AUTHOR]

Background: Data on associations between sexually transmitted infections (STIs) and incident human immunodeficiency virus (HIV) diagnoses beyond men who have sex with men (MSM) are lacking. Identifying STIs associated with greatest risk of incident HIV diagnosis could help better target HIV testing and prevention interventions.Methods: The STI and HIV surveillance data from individuals 13 years or older in Tennessee from January 2013 to December 2017 were cross-matched. Individuals without diagnosed HIV, but with reportable STIs (chlamydia, gonorrhea, syphilis) were followed up from first STI diagnosis until HIV diagnosis or end of study. Cox regression with time-varying STI exposure was used to estimate adjusted hazard ratios (aHRs) and 95% confidence intervals (CI) for subsequent HIV diagnosis; results were stratified by self-reported MSM.Results: We included 148,465 individuals without HIV (3831 MSM; 144,634 non-MSM, including heterosexual men and women) diagnosed with reportable STIs; 473 had incident HIV diagnoses over 377,823 person-years (p-y) of follow-up (median, 2.6 p-y). Controlling for demographic and behavioral factors, diagnoses of gonorrhea, early syphilis, late syphilis, and STI coinfection were independently associated with incident HIV diagnosis compared with chlamydia. Early syphilis was associated with highest HIV diagnosis risk overall (aHR, 5.5; 95% CI, 3.5-5.8); this risk was higher for non-MSM (aHR, 12.3; 95% CI, 6.8-22.3) versus MSM (aHR, 2.9; 95% CI, 1.7-4.7).Conclusions: While public health efforts often focus on MSM, non-MSM with STIs is also a subgroup at high risk of incident HIV diagnosis. Non-MSM and MSM with any STI, particularly syphilis, should be prioritized for HIV testing and prevention interventions. [ABSTRACT FROM AUTHOR]

We describe a fatal case of multisystem inflammatory syndrome in an adult with onset 22 days after a second dose of mRNA coronavirus disease vaccine. Serologic and clinical findings indicated severe acute respiratory syndrome coronavirus 2 infection occurred before vaccination. The immunopathology of this syndrome, regardless of vaccination status, remains poorly understood. [ABSTRACT FROM AUTHOR]

Background Multisystem inflammatory syndrome in adults (MIS-A) was reported in association with the coronavirus disease 2019 (COVID-19) pandemic. MIS-A was included in the list of adverse events to be monitored as part of the emergency use authorizations issued for COVID-19 vaccines. Methods Reports of MIS-A patients received by the Centers for Disease Control and Prevention (CDC) after COVID-19 vaccines became available were assessed. Data collected on the patients included clinical and demographic characteristics and their vaccine status. The Vaccine Adverse Events Reporting System (VAERS) was also reviewed for possible cases of MIS-A. Results From 14 December 2020 to 30 April 2021, 20 patients who met the case definition for MIS-A were reported to CDC. Their median age was 35 years (range, 21–66 years), and 13 (65%) were male. Overall, 16 (80%) patients had a preceding COVID-19-like illness a median of 26 days (range 11–78 days) before MIS-A onset. All 20 patients had laboratory evidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Seven MIS-A patients (35%) received COVID-19 vaccine a median of 10 days (range, 6–45 days) before MIS-A onset; 3 patients received a second dose of COVID-19 vaccine 4, 17, and 22 days before MIS-A onset. Patients with MIS-A predominantly had gastrointestinal and cardiac manifestations and hypotension or shock. Conclusions Although 7 patients were reported to have received COVID-19 vaccine, all had evidence of prior SARS-CoV-2 infection. Given the widespread use of COVID-19 vaccines, the lack of reporting of MIS-A associated with vaccination alone, without evidence of underlying SARS-CoV-2 infection, is reassuring.
