Andes virus is the only known hantavirus capable of person-to-person transmission, documented in healthcare settings without adequate IPC. Outbreak originated aboard MV Hondius (Ushuaia, Argentina departure). Illness characterized by fever, GI symptoms, and rapid progression to ARDS and shock. Hospital workers caring for hantavirus pulmonary syndrome (HPS) patients require contact and droplet precautions at minimum; airborne precautions during aerosol-generating procedures.

A human ocular disease called persistent ocular hypertensive viral anterior uveitis (POH-VAU) has recently emergedin associated with covert mortality nodavirus (CMNV) of aquatic origin.
CDC is issuing this Health Alert Network (HAN) Health Advisory to share information and notify clinicians, public health authorities, and the public about recent New World screwworm (NWS) animal cases in the Mexican state of Tamaulipas, which shares a border with the U.S. state of Texas.
As of February 17, 2026, Central America and Mexico have reported more than 153,000 NWS cases in animals and over 1,300 cases in people.

Rabies is a viral disease that infects mammals and has an almost 100% fatality rate if postexposure prophylaxis is not administered before symptom onset. Outbreaks among cattle are rare but have been reported. Steer-to-steer transmission could not be ruled out.
In February 2025, CDC confirmed a fatal rabies case in a patient who had received a transplanted kidney from a deceased donor with undiagnosed rabies. Three cornea recipients from the same donor underwent graft removal, received PEP, and remained asymptomatic.

CDC recommendations to health care providers and preparedness personnel regarding treatment and postexposure prophylaxis (PEP) of tularemia. Because F. tularensis has a low infectious inoculum, it is classified as a potential bioterrorism agent that could infect thousands of persons if intentionally released.
New World screwworm (NWS) infestation occurs when NWS fly larvae (Cochliomyia hominivorax) infest the tissue or flesh of warm-blooded animals. In places where the flies are present, people can also become infested.
To ensure the protection of U.S. livestock herds, USDA is holding Mexico accountable by ensuring proactive measures are being taken to maintain a NWS free barrier. This is maintained with stringent animal movement controls, surveillance, trapping, and following the proven science to push the NWS barrier south in phases as quickly as possible.
