05/18/2026 - The hantavirus (Andes virus) is the focus of a new alert from the World Health Organization (WHO), which highlights the risks of its rare human-to-human transmission. The pathogen, traditionally associated with contact with wild rodents, recently demonstrated its high contagion potential during an outbreak aboard the cruise ship MV Hondius. This incident resulted in 11 infections and three deaths, reinforcing the need for strict isolation protocols and international contact tracing to contain the spread of the disease.
