We describe acute severe hepatitis B virus (HBV) infection with liver failure requiring transplantation in a patient in Poland treated with acalabrutinib.

In September 2023, an outbreak of a new strain of monkeypox virus (MPXV) emerged in the nonendemic Sud-Kivu province of the Democratic Republic of the Congo (DRC); the outbreak was driven by sustained human-to-human transmission (1).

In June 2023, the Advisory Committee on Immunization Practices recommended a single dose of RSV vaccine for adults >60 years of age to be determined on the basis of shared clinical decision making (5).

The emergence of influenza A virus (IAV) (H5N1) in dairy cows, first reported in March 2024, was unprecedented. Because dairy cows were not considered a typical host for IAV, initial identification was delayed after reports of nonspecific illness in lactating cattle in Texas, USA.

Francisella tularensis is a highly infectious, gram-negative bacterium that causes tularemia and may be transmitted through several pathways, including bites from infected ticks (primarily Amblyomma americanum and Dermacentor variabilis in the northeastern United States), deer flies (Chrysops species), contact with infected animals, ingestion of contaminated food or water, and inhalation of infectious aerosols (1).

Diseases caused by henipaviruses, exemplified by Hendra virus and Nipah virus, pose a serious risk to public health because of their epidemic potential and high case-fatality rates and the paucity of medical countermeasures to mitigate them.
