The World Health Organization (WHO) says a hantavirus outbreak linked to a cruise ship is over. Multiple outlets report that the WHO makes the determination after public health monitoring concludes for people who were exposed. In particular, the WHO states that the last identified contact of an exposed person completes quarantine and tests negative for the virus, indicating no further transmission. BBC further reports that no new cases are reported after 25 May, and that the WHO’s director-general says the situation has ended with no additional reports since that date. RTE similarly describes the outbreak—first detected in April and linked to international concern—as declared over once the final person leaves quarantine. Overall, sources agree the decision is based on the completion of quarantine for the last contact and the absence of new reported cases within the monitoring period.
