Singapore authorities report that two Singapore residents who were on a cruise ship affected by a hantavirus outbreak have tested negative for the virus. The Civil Defence? Agency (CDA) says both men remain under quarantine for 30 days from the date of their last exposure as a precaution. During this period, health authorities continue to monitor them for any symptoms. Both sources state that the two passengers will receive additional testing before they are cleared to leave quarantine. The reports do not indicate that the negative results change the quarantine duration, which is maintained as a precautionary measure. The cases are presented as follow-up assessments of individuals who were potentially exposed while onboard the hantavirus-hit cruise ship. Overall, the information from the two outlets is consistent: two Singapore residents test negative at the latest screening, but they stay in quarantine and undergo further tests ahead of any release.
