Two Singapore residents who had been on board a hantavirus-hit cruise ship have tested negative to the rare respiratory disease, according to Singapore’s Communicable Diseases Agency (CDA). The two men aged 65 and 67 had been on the MV Hondius and also the same flight as a confirmed hantavirus case from St Helena to Johannesburg on April 25, the CDA said a day earlier. The confirmed case did not travel to the city state and died in South Africa.
