ADVISORY
Outbreak of invasive meningococcal disease among students in Kent, England
03/16/2026
United Kingdom, England
Recommendation: Organizations with employees traveling to or working in Kent, England, should provide flexible work schedules to allow for vaccination of themselves or family members if not already vaccinated.
Situation: The UK Health Security Agency confirmed a cluster of invasive meningococcal disease among students in Kent, England. 13 individuals with meningitis and septicemia symptoms were reported from the Canterbury area from 3/13 to 3/15. 2 deaths occurred. The specific strain has not been identified yet. Media sources identified at least 1 case each among students from Queen Elizabeth's Grammar School and the University of Kent.

Confirmed measles case linked to ConExpo in Las Vegas
03/16/2026
Nevada, Clark County
Recommendation: Organizations in Clark County, Nevada, should inform employees about the potential measles exposures and provide flexible work schedules to support employees in making vaccine appointments for themselves or family members. Measles is highly contagious and can quickly spread among unvaccinated individuals in a work environment.
Situation: Nevada health officials reported a confirmed case of measles in a visitor to Clark County. The individual attended ConExpo at the Las Vegas Convention Center on 3/6-7 and spent time elsewhere in the Las Vegas area on 3/8, though specific locations were not provided. There were over 2,000 exhibitors and over 140,000 attendees at the ConExpo, North America’s Largest Construction Show, according to their website. Exposed individuals should monitor for measles symptoms (7-21 days from exposure). [Confidence: Very High]
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]
WATCH
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]
