GHS tightens surveillance after Hantavirus outbreak on cruise ship in Cape Verde

Ghana Health Service (GHS) says it has "stepped up surveillance and preparedness measures" following reports of Hantavirus infections detected on a cruise ship currently docked in Cape Verde. According to a statement issued on May 8, 2026, by the Ministry of Health and GHS, the outbreak on the vessel, as of May 7, includes eight suspected cases, five confirmed infections, and three deaths.

The ship reportedly carried crew members mainly from the Philippines, with passengers from several countries including the United States, parts of Europe, South America, Australia, and Asia. The World Health Organization (WHO) and the United States Centers for Disease Control and Prevention (CDC) have indicated that the global public health risk remains low, but have urged countries to strengthen surveillance and preparedness systems. GHS explained that Hantavirus is mainly transmitted through contact with infected rodents or exposure to their droppings, urine, saliva, or contaminated surfaces, and that symptoms can include fever, headache, muscle pain, abdominal pain, vomiting, and in severe cases, difficulty in breathing.

GHS said that no case has been recorded in Ghana so far, but precautionary measures have been activated through its Port Health Division and other public health systems to reduce any possible risk of importation. Enhanced screening and surveillance have been introduced at all ports of entry, including airports and seaports, and health facilities across the country have also been directed to step up monitoring and reporting of any unusual respiratory illnesses. The GHS further said it is strengthening laboratory systems and rapid response capacity while intensifying public education on sanitation and rodent control, and confirmed ongoing collaboration with international partners, including the WHO and global disease surveillance networks, to ensure timely information sharing.
