#Hantavirus cluster linked to cruise ship travel:  Since 1 April when the boat set sail, of the 147 passengers and crew, 7 people have become ill, among whom 3 have died, 1 is critically ill and 3 are reporting mild symptoms.   Based on the current information, including how hantavirus spreads, WHO assesses the risk to the global population from this event as low. We are working closely with health authorities from the countries involved and the ship's operators to ensure passengers and crew get the information and support they need.   WHO will continue to monitor the situation and update the risk assessment as more information becomes available.   More information bit.ly/42Tc4J7

Furthermore, majority of patients tolerated one or more doses of piperacillin–tazobactam across all risk stratification groups, including those in the “high risk anaphylactic group.

In US nursing homes, initiating oseltamivir chemoprophylaxis for ≥70% of residents within 2 days of influenza outbreak detection reduced 14-day hospitalization risk without affecting mortality. ja.ma/4118g7T
