Two students are dead and 11 are hospitalized after an outbreak of a rare form of invasive meningitis at the University of Kent in England.

The UK Health Security Agency (UKHSA) provided prophylactic antibiotics to students in the area after it detected 13 cases of invasive meningococcal disease, a combination of meningitis and septicemia, or blood poisoning.

“Meningococcal disease can progress rapidly, so it’s essential that students and staff are alert to the signs and symptoms of meningococcal meningitis and septicaemia, which can include a fever, headache, rapid breathing, drowsiness, shivering, vomiting and cold hands and feet. Septicaemia can also cause a characteristic rash that does not fade when pressed against a glass,” said Trish Mannes, MSc, UKHSA regional deputy director for the South East, in the news release.

Students are particularly at risk of missing the early warning signs of meningitis.

“Students are particularly at risk of missing the early warning signs of meningitis because they can be easily confused with other illnesses such as a bad cold, flu or even a hangover,” she added.

The UKHSA said the strain of meningococcal bacteria in this outbreak has yet to be identified.

College campuses and universities have historically been sites of meningitis outbreaks because of close living quarters.

• The New York City Health Department has identified clade 1 mpox in a person who had recently traveled to Europe. This is the twelfth clade 1 case in the United States and the first identified in New York City. The city health department said the person was symptomatic, has received appropriate medical care, and has been isolating until full resolution of symptoms. Last year, the city recorded 398 cases of clade 2 monkeypox, a strain commonly transmitted between men who have sex with men. Clade 1 cases have been linked primarily to travel in Africa and are more severe than clade 2 infections.
• More than 150 passengers and crew members contracted norovirus aboard Princess Cruises’ Star Princess during a weeklong trip from Fort Lauderdale, Florida, according to the Centers for Disease Control and Prevention (CDC). Princess Cruises said all illnesses were mild, and the staff practiced enhanced sanitation and isolation measures to protect passengers. Earlier this month, 76 passengers and crew aboard Holland America Line’s MS Westerdam experienced a suspected norovirus outbreak during an Asian trip.
• Cambodia reported its second human H5N1 avian influenza case of the year in a 45-year-old woman from Ropai village, according to the SubstackOutbreak News Today. The woman raised chickens and other birds and reported coming into contact with sick birds three days before symptom onset. The patient received Tamiflu and is under medical care. Cambodia has reported 36 human H5 infections since 2023, and the case-fatality rates of these infections are high, at greater than 40%. Most recent cases in Cambodia have involved a reassortant (2.3.2.1e) between an older H5N1 clade that has circulated in Cambodia since 2014 and the newer clade 2.3.4.4b virus that is circulating globally.
