Hantavirus

In May 2026, an outbreak of Hantavirus disease was confirmed among passengers aboard a cruise ship off the coast of Cape Verde. The rare Andes strain of hantavirus is believed to be responsible, as it is one of the few variants capable of spreading from person to person. Hantavirus was first identified in the Hantaan River area of Korea and recognized in the United States in 1993. It is typically transmitted through contact with infected rodents or their saliva, urine, and droppings, and while rare, it can be life-threatening, particularly when it affects the lungs, heart, or kidneys.  According to the World Health Organisation, "As of 4 May 2026, seven cases (two laboratory confirmed cases of hantavirus and five suspected cases) have been identified, including three deaths, one critically ill patient and three individuals reporting mild symptoms."

While Hantavirus infections are not considered a significant risk to the general public due to their rarity and limited person-to-person transmission, the outbreak in May 2026 served as a reminder of the importance of awareness and preparedness. Early symptoms include fatigue, fever, and muscle aches, progressing in some cases to coughing and shortness of breath as fluid accumulates in the lungs. The incubation period ranges from two to eight weeks.
