In 2023, California reported near–record high coccidioidomycosis cases after a dramatic transition from drought to heavy precipitation. Using an ensemble model, we forecasted 12,244 cases statewide during April 1, 2024–March 31, 2025, a 62% increase over cases reported 2 years before and on par with case counts for 2023.
Airport-based pathogen monitoring is a critical tool that can contribute to early detection and characterization of existing and new pathogen threats. A novel public–private partnership between an airport spa group, a biotech company, and the Centers for Disease Control and Prevention was instrumental in establishing a multimodal pathogen genomic surveillance program at US international airports. That public–private partnership addressed critical challenges that neither party could overcome independently, resulting in the development and deployment of a scalable, flexible early warning system for pathogen detection and public health monitoring.
During July 2022–February 2023, mpox was confirmed in 71 of 283 suspected cases in the Dominican Republic; 32.4% of patients were women, and 22.5% children <10 years of age. We found differences in transmission compared with global trends, emphasizing the need for continued surveillance, diagnostics, and public health interventions.
We detected yellow fever virus in Haemagogus mosquitoes collected in 2022 in an Amazon rainforest bordering Manaus, Brazil. The viral genome sequence occupied a basal position within the South American I genotype 1E lineage. Our findings reinforce the Amazon Basin as a source for yellow fever virus re-emergence.
Nipah virus, a zoonotic virus with a high mortality rate, threatens people from Indonesia because of its proximity to affected regions and the presence of bat reservoirs. Molecular screening of 64 Pteropus hypomelanus bats in Central Java detected 2 positive bats. Public health authorities should increase surveillance to help prevent human transmission.
Human granulocytic anaplasmosis is a tickborne infection characterized by fever, thrombocytopenia, leukopenia, transaminitis, or a combination of those. Treatment must be prompt and appropriately targeted to prevent clinical decompensation. We discuss an unusual cluster of 16 probable cases in Ontario, Canada, during June–August 2021.
We identified hepatitis E virus (HEV) 3ra, a potentially zoonotic subtype, in rabbits in Ukraine, which highlights their potential role as reservoirs. Screening of rabbit fecal samples identified HEV-3ra. Public health services in this country should improve HEV surveillance and expand HEV sampling.
The 2058T macrolide resistance–associated mutation in 23S rRNA has emerged in Mycoplasma genitalium in France. Using mgpB typing, we documented the spread of a macrolide- and moxifloxacin-resistant ST159 clone, harboring the A2058T and ParC Ser83Ile mutations. In France, that clone is likely circulating among men who have sex with men.
Serum samples from wild mammals inhabiting Alaska, USA, showed that 4 species, including Ursus arctos bears and Vulpes vulpes foxes, were exposed to influenza A(H5N1) viruses. Results indicated some mammals in Alaska survived H5N1 virus infection. Surveillance efforts may be improved by incorporating information on susceptibility and detectable immune responses among wild mammals.
