Latest update on #hantavirus outbreak linked to cruise ship travel, multi-locations 🔵 As of 27 May, a total of 13 hantavirus cases (11 confirmed and 2 probable cases), including 3 deaths (2 confirmed and 1 probable), have been reported. 📌All confirmed cases are among people who travelled onboard the MV Hondius. Given the long incubation period of up to six weeks, it is not unexpected that cases continue to be reported until the end of the six weeks since last exposure. 🔵 Based on the available information and the existing observations of the current outbreak, limited human-to-human transmission of Andes virus (ANDV) in known to occur. The exact mode(s) through which human-to-human transmission occurred during this outbreak are yet to be fully understood. 📌While the available evidence suggests that there are multiple modes of transmission that occur with ANDV, the probability of onward transmission between humans remains low. 🔵Therefore, at the present time, WHO is operating under the assumption that ANDV transmission: 🔹 may include contact with an infected individual or contaminated surfaces 🔹 and/or through the air transmission (via direct deposition of infectious respiratory particles onto exposed facial mucosal surfaces--mouth, nose or eyes) 🔹and/or airborne transmission (via inhalation of infectious respiratory particles). 📌This information is up to date as of 27 May 2026. It will be updated as new evidence becomes available and the understanding of transmission evolves. 🔵 Using data from the previously documented human-to-human outbreaks in Argentina and the 13 cases so far recorded from the cruise ship outbreak, WHO estimates that the mean incubation period is 22 days, corresponding to a probability of safe release from quarantine of 96% at 42 days, reducing to 91% at 35 days. This reaffirms WHO’s recommendation of 42 days of quarantine for high-risk contacts and self-monitoring for low-risk contacts. Read more: www.who.int/emergencies/disease-outbreak-n...
