Tuberculosis Outbreak in a State Prison System - Washington, 2021-2022.

During 2014-2020, no tuberculosis (TB) cases were reported within the Washington state prison system. However, during July 2021-June 2022, 25 TB cases were reported among persons incarcerated or formerly incarcerated in two Washington state prisons. Phylogenetic analyses of whole genome sequencing data indicated that Mycobacterium tuberculosis isolates from all 11 patients with culture-confirmed TB were closely related, suggesting that these cases represented a single outbreak. The median infectious period for 12 patients who were considered likely contagious was 170 days. As of November 15, 2022, the Washington State Department of Corrections (WADOC) and Washington State Department of Health (WADOH), with technical assistance from CDC, had identified 3,075 contacts among incarcerated residents and staff members at five state prisons, and 244 contacts without a known TB history received a diagnosis of latent TB infection (LTBI). Persons who were evaluated for TB disease were isolated; those receiving a diagnosis of TB then initiated antituberculosis therapy. Persons with LTBI were offered treatment to prevent progression to TB disease. This ongoing TB outbreak is the largest in Washington in 20 years. Suspension of annual TB screening while limited resources were redirected toward the COVID-19 response resulted in delayed case detection that facilitated TB transmission. In addition, fear of isolation might discourage residents and staff members from reporting symptoms, which likely also leads to delayed TB diagnoses. Continued close collaboration between WADOC and WADOH is needed to end this outbreak and prevent future outbreaks.

Willingness to Receive a COVID-19 Vaccination Among Incarcerated or Detained Persons in Correctional and Detention Facilities - Four States, September-December 2020.

Incarcerated and detained persons are at increased risk for acquiring COVID-19. However, little is known about their willingness to receive a COVID-19 vaccination. During September-December 2020, residents in three prisons and 13 jails in four states were surveyed regarding their willingness to receive a COVID-19 vaccination and their reasons for COVID-19 vaccination hesitancy or refusal. Among 5,110 participants, 2,294 (44.9%) said they would receive a COVID-19 vaccination, 498 (9.8%) said they would hesitate to receive it, and 2,318 (45.4%) said they would refuse to receive it. Willingness to receive a COVID-19 vaccination was lowest among Black/African American (Black) (36.7%; 510 of 1,390) persons, participants aged 18-29 years (38.5%; 583 of 1,516), and those who lived in jails versus prisons (43.7%; 1,850 of 4,232). Common reasons reported for COVID-19 vaccine hesitancy were waiting for more information (54.8%) and efficacy or safety concerns (31.0%). The most common reason for COVID-19 vaccination refusal was distrust of health care, correctional, or government personnel or institutions (20.1%). Public health interventions to improve vaccine confidence and trust are needed to increase vaccination acceptance by incarcerated or detained persons.
