Meningococcal disease outbreak grows in Kent, England, as officials search for those exposed at Club Chemistry
03/17/2026
United Kingdom, EnglandFrance
Recommendation: Organizations in Kent, England, should inform employees about the potential meningococcal disease exposure at Club Chemistry, and should provide flexible work schedules to support employees in making vaccine appointments or seeking preventative antibiotic treatment for themselves or family members.
Situation: England reported 2 new invasive meningococcal disease cases in the outbreak in Kent, totaling 15 cases, of which 4 were confirmed, and 2 deaths. Cases were detected among students across at least 4 schools in the area, including 1 student who had returned to France after attending the University of Kent, according to media sources. Health officials announced a potential exposure location at Club Chemistry on 3/5-7, calling on all attendees at the club during those times to seek preventative antibiotic treatment. Most cases were linked to Club Chemistry, which is temporarily closed. Meningitis B was detected in 4 cases. The MenB vaccine was introduced to the routine childhood immunization schedule in England in 2015, but those who are older than 10 would not have received it as part of routine vaccination. A targeted vaccination campaign for students who live in the University of Kent halls will be initiated soon. Media sources reported localized shortages in vaccines due to a large increase in demand. See PHC alert on 3/16 for earlier info. [Confidence: Very High]

Latvia, RigaTurkey
Recommendation: Organizations in Riga, Latvia, or Turkey 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: Latvia health officials confirmed a measles case, and announced that the infection may have occurred at a Liutauras Viktorinas alternative wellness event on 2/21-22 at the Bellevue Hotel in Riga. The case then traveled on 3/5 to Turkey on flight #TK1758. Health officials are investigating the case to identify the source, trace close contacts, and implement measures to prevent further spread. Exposed individuals should monitor for measles symptoms (7-21 days from exposure). [Confidence: Very High]

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. Antibiotics were distributed to close contacts, and investigations are ongoing, with health officials urging students and staff at affected schools to be alert to the early signs and symptoms of meningococcal meningitis and septicemia.

WATCH
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.

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]
