• Serologic Evidence of Hantavirus Exposure in Humans, Italy, 2004–2018
  G. Faolotto et al. View Abstract

  Rodentborne hantaviruses and lymphocytic choriomeningitis virus (LCMV) circulate in northern Italy but are rarely diagnosed. We tested samples collected from 371 patients during 2004–2018 and detected LCMV IgG in 2.7% of samples and hantavirus IgG in 7.3%. Puumala virus–neutralizing antibodies were confirmed in 10 cases, indicating unrecognized local hantavirus circulation.

• Genomic and Epidemiologic Insights into Ongoing Measles Outbreak, Israel, 2025–2026
  E. Bucris et al. View Abstract

  An ongoing measles outbreak in Israel, involving ≈3,200 cases and 16 deaths, threatens the country’s measles elimination status and reflects declining vaccination rates observed globally and within Israel. Epidemiologic investigations supported by sequencing suggest that a single importation triggered the outbreak, underscoring the critical role of rapid genomic surveillance in outbreak control.

  A. S. Handel et al. View Abstract

  Southern tick–associated rash illness (STARI) is a tickborne disease of unknown etiology characterized by an erythema migrans–like skin lesion. We report a STARI case in New York in a child after an Amblyomma americanum tick bite; we detected Borrelia lonestari, a disputed cause of STARI, in the tick.

• Emergence of Rabies in Cape Fur Seals, South Africa
  C. Ngoepe et al. View Abstract

  Rabies was diagnosed in Cape fur seals by using direct fluorescent antibody testing in South Africa, 2024. We investigated the origin of rabies virus in this species. Phylogenetic analysis revealed virus introduction from jackals into seals, followed by sustained viral transmission within the seal population and spillover into a domestic dog.
