Building the Future of Biodefense
Biothreat intelligence to deter and detect natural, accidental, deliberate and novel biological agents.
ADVISORY
Anguilla reports its 1st ever locally acquired West Nile virus human case
03/13/2026
Anguilla
Recommendation: Organizations in Anguilla should reduce mosquito habitats by eliminating sources of standing water and applying insecticides to outdoor water storage containers. Employees can reduce infection risk by wearing clothing that covers skin, using mosquito repellents, and emptying standing water.
Situation: Anguilla reported its 1st ever locally acquired West Nile virus (WNV) human case in early March. While WNV has been detected in mosquitoes, birds, and horses across the Caribbean since the early 2000s, human cases are not common in the Caribbean. Limited surveillance and laboratory capacity, plus WNV's similar symptomatology to other circulating mosquito-borne diseases, may contribute to regional underreporting. [Confidence: Very High]
ADVISORY
New Mexico confirms its 1st hantavirus case in 2026
03/13/2026
New Mexico, Santa Fe County
Recommendation: Cases of hantavirus are rare, but not unexpected in New Mexico. Organizations in Santa Fe County should take measures to ensure rodent-free facilities. Rodent droppings should be cleaned with bleach; wet the soiled area with bleach before wiping up droppings to limit infectious aerosol generation. Employees should always wear gloves and N95 (or equivalent) masks when handling rodents or their droppings.
Situation: New Mexico confirmed its 1st hantavirus case this year in Santa Fe County. The individual was hospitalized for hantavirus pulmonary syndrome and has since recovered. In New Mexico, deer mice are the primary carriers of hantavirus, though it can be found in other rodents. [Confidence: Very High]

Colorado measles outbreak grows to 10 cases, plus a restaurant exposure
03/13/2026
Colorado, Jefferson CountyColorado, Broomfield County
Recommendation: Organizations in Jefferson and Broomfield Counties, Colorado, should inform employees about the potential measles exposures. Organizations should provide flexible work schedules to support employees who need to make vaccine appointments for themselves or their family members. Measles is highly contagious and can quickly spread among unvaccinated individuals in a work environment.
Situation: Colorado health officials identified 2 additional measles cases and are investigating a 3rd in Broomfield County. All 3 cases are household contacts of a previously confirmed case. The public may have been exposed to measles at Bout Time Pub & Grub in Arvada on 3/10-11. Exposed individuals should monitor for measles symptoms (7-21 days from exposure). The new cases are linked to an outbreak that started in Broomfield High School and Broomfield Heights Middle School. According to media sources, dozens of unvaccinated students in the school district were told not to attend school and stay in quarantine for at least 21 days, after measles began to spread. The statewide total has reached 10 measles cases across 4 counties so far this year. See PHC alerts 3/9, 3/5, 3/3, and 3/2. [Confidence: Very High]
ADVISORY
Peru records over 8,600 dengue cases so far this year as rain and heat fuels mosquito spread
03/12/2026
Peru
Recommendation: Dengue is endemic in Peru, and the peak season occurs between November and May. Organizations should reduce mosquito populations at their facilities by eliminating standing water. Employees can prevent mosquito bites by wearing protective clothing, using insect repellent, and eliminating standing water near their homes.
Situation: Peru reported 8,629 cases and 23 deaths so far in 2026, as of week 9. Cases were recorded in 20 of 25 departments, with incidence highest in Ucayali, San MartÃn, Tumbes, and Loreto. According to media sources, the onset of El Niño Costero in March, expected to last until November 2026, has created climate conditions of intense rainfall and sustained high temperatures that favor the proliferation of the Aedes aegypti mosquito, which transmits dengue and other vector-borne diseases. Experts warned that extreme heat has accelerated the mosquito’s life cycle, reducing development from egg to adult from 10-11 days to 5 days, and that the mosquito species is now appearing at higher altitudes and in contaminated water sources, which was uncommon in previous years. In response, Peruvian health officials implemented a national plan that includes releasing mosquitoes carrying the Wolbachia bacteria, which reduces the insects' ability to transmit the disease to humans, and expanding their vaccination programs.

Health officials confirm 2 measles cases in Sydney with multiple exposure sites
03/12/2026
Australia, New South Wales
Recommendation: Organizations in New South Wales, Australia, should inform employees about the possible measles exposures and should provide flexible work schedules to support employees making vaccine appointments for themselves or family members. Measles is highly contagious and can quickly spread among unvaccinated individuals in a work environment.
Situation: Health officials confirmed 2 new measles cases in Sydney, Australia. One case was locally acquired, while the second had no known exposure, suggesting ongoing undetected community transmission. The public may have been exposed at The Piazza Residential complex 1 in Wentworth Point (3/4-10), JB & Sons Restaurant in Manly (3/8), ​Henry G’s Wine Parlour in Manly (3/8), ​Donny's Bar in Manly (3/8), The Village Inn in Paddington (3/7), Summer Dance Festival, Liberty Hall Courts in Moore Park (3/7), Wentworth Point Pierside Shopping Centre (3/6), Sydney Bus - Manly Wharf to The Northern Beaches Hospital (3/5), ​Felons Brewing Co. in Manly (3/5), ​​The Fresh Fruit Team - Flemington Sydney Markets in Homebush West (3/4-5), and at multiple health care facilities which can be found at the source link. Exposed individuals should monitor for measles symptoms (7-21 days from exposure). [Confidence: Very High]
