A flight attendant from Haarlem has been hospitalised due to a possible hantavirus infection, according to Dutch broadcaster RTL. She came into contact with the 69-year-old Dutch woman who died from the virus a day later in Johannesburg, South Africa.
The flight attendant is experiencing mild symptoms and has been placed in isolation at Amsterdam UMC, where she is undergoing testing.
The Dutch woman who later died from hantavirus had briefly boarded a KLM aircraft in Johannesburg on 25 April 2026 but was denied travel due to her medical condition. She was taken to hospital and died the following day. Her death is linked to the outbreak that has also claimed the lives of her husband and a German national, all passengers of MV Hondius.
