Estimated Illness Linked to Animal Contact for 7 Pathogens, United States, 2019
Diseases transmitted through direct or indirect animal contact are a public health concern in the United States. Improvements in laboratory detection methods and illness estimates warrant an update of illness estimates linked to animal contact. We used surveillance data and other sources to estimate the annual number of US illnesses, hospitalizations, and deaths for 7 pathogens. We adjusted for underreporting and underdiagnosis by using established methods. Campylobacter, Cryptosporidium, Shiga toxin–producing Escherichia coli, Listeria monocytogenes, nontyphoidal Salmonella, and non-pestis Yersinia caused an estimated 995,022 (90% credible interval [CrI] 476,251–1,833,238) animal contact illnesses around 2019. Together with Toxoplasma gondii, those illnesses caused an estimated 9,592 (90% CrI 5,603‒15,557) hospitalizations and 236 (90% CrI 119‒411) deaths in the United States. Increased awareness among health professionals, government officials, industry partners, and the public about animal contact as a mode of disease transmission can aid prevention efforts and enhanced surveillance.

Identification of Zoonotic Pteropine orthoreovirus in Rousettus amplexicaudatus Fruit Bats, Indonesia
Pteropine orthoreovirus (PRV) is an emerging batborne virus with zoonotic potential increasingly linked to human respiratory illness. During 2020–2021, we sampled 182 fruit bats from animal markets and suppliers across Java, Indonesia, and identified species morphologically. We cultured rectal swab samples on Vero cells and sequenced samples showing cytopathic effects by using next-generation technology. We recovered 2 isolates from Rousettus amplexicaudatus bats sold for human consumption in Cianjur, West Java. Comparative analysis of 9 of 10 genomic segments showed the isolates were nearly identical (>99%–100%), except for the S2 segment (88.9%). Phylogenetic analysis indicated close clustering with Nelson Bay, Melaka, Kampar, Pulau, and Garut-69 bat-associated PRVs. We found PRV in R. amplexicaudatus bats in Indonesia, which highlights the zoonotic risk of wildlife trade. Continued surveillance of PRVs at the human–bat interface will be needed to assess the emergence of novel viruses and mitigate potential zoonotic threats.

Typhoid Fever–Like Manifestation of Scrub Typhus in Patient with Myelodysplastic Syndrome, China, 2025
A 79-year-old man in China sought care for fever and syncope and was diagnosed with myelodysplastic syndrome. Bone marrow showed hemophagocytosis and macrophages resembling typhoid cells, but cultures excluded Salmonella infection. Targeted next-generation sequencing identified Orientia tsutsugamushi, and a concealed popliteal eschar was found. Scrub typhus can produce typhoid-like bone marrow morphology.

Wild Mice and Shrews as Natural Reservoirs of Emerging Tickborne Yezo Virus, Hokkaido, Japan, 2023–2025
We screened 420 wild small mammals and 2,273 ticks for infections with an emerging tickborne orthonairovirus, Yezo virus, during 2023–2025 in Hokkaido, Japan. We detected virus in mice, shrews, and ticks that were closely related. Apodemus spp. mice and Sorex spp. shrews were identified as potent natural reservoirs of Yezo virus.

Mayaro Virus Emergence and Genetic Dynamics, Peru
Mayaro virus (MAYV) is an emerging pathogen in Latin America. Using phylodynamic reconstructions and phylowave analyses, we describe novel lineage diversification and rapid dispersal of MAYV in Peru. A newly developed, dual-target quantitative reverse transcription PCR assay reliably detects MAYV variants, enabling improved surveillance, control, and understanding of this neglected arbovirus.

Isolation of Orientia tsutsugamushi from Bat-Associated Chiggers, Japan
We isolated Orientia tsutsugamushi bacteria from bat-associated Whartonia prima chiggers collected from Hipposideros turpis bats on Yonaguni Island, Japan. Serial passage, microscopic examination, growth kinetics, and multilocus sequence analysis confirmed bacterial propagation and identity. Our findings highlight an overlooked bat–chigger interface with potential relevance to broader ecologic surveillance of scrub typhus.

Natural Occurrence of Primate SLAM-Adapted Canine Distemper Virus, Brazil, 2018
We analyzed canine distemper virus (CDV) from a 2018 marmoset disease outbreak in Brazil. CDV hemagglutinin protein bound to the marmoset SLAM (signaling lymphocytic activation molecule) receptor through 2 amino acid substitutions within hemagglutinin, which also enhanced human SLAM receptor usage. Continued surveillance will be critical to monitor CDV cross-species transmission.

Infectious African Swine Fever Virus in Spray-Dried Porcine Plasma Used as Feed Ingredient, South Korea, 2026
We detected African swine fever virus DNA in feed and spray-dried porcine plasma (SDPP) used as a feed ingredient in South Korea. Pigs inoculated with SDPP developed fatal infection. An isolate phylogenetically clustered with South Korea strains. Our findings highlight the need for strengthened risk management of animal-derived feed ingredients like SDPP.

Emergence of Shamonda Orthobunyavirus, Central Europe, 2026
Since mid-June 2026, an acute, nonfatal syndrome characterized by high herd illness rate, reduced milk yield, diarrhea, fever, and lethargy has affected dairy cattle in southern Germany and Switzerland. After major viral pathogens were excluded, pan-Simbuvirus reverse transcription PCR detected an orthobunyavirus, confirmed by metagenomic sequencing, enabling recovery of a complete Shamonda virus genome.

Oropouche Fever Outbreak, Havana, Cuba, June–September 2024
Oropouche fever emerged nationwide in Cuba in 2024. We investigated the outbreak in Havana; of 549 suspected cases, 189 (34.4%) were confirmed. No cases were severe. Incidence was 8.9/100,000 population and was highest in adults 27–59 years of age (10.2/100,000 population). Three infants tested positive. Dengue cocirculation challenged surveillance.
