Health authorities have confirmed the presence of the Andes strain of hantavirus aboard a cruise ship where an outbreak has occurred. Passengers from the MV Hondius have been tested for this rare viral infection. One British man is currently in intensive care in Johannesburg, South Africa, following the outbreak that has left health officials on high alert.
About the Andes Hantavirus Strain
The World Health Organization (WHO) has verified that the Andes strain can spread from person to person. This marks a significant finding, as it is the only known hantavirus capable of human-to-human transmission. The virus typically spreads through close contact, such as sharing food or sleeping arrangements. Found primarily in Argentina and Chile, the Andes virus is transmitted mostly by rodents.
Current Situation and Health Measures
- Three confirmed hantavirus cases are linked to the MV Hondius.
- Five additional cases are suspected.
- A Swiss man who traveled on the ship has tested positive for the virus.
- Health authorities in South Africa are conducting extensive contact tracing.
- 62 contacts, including healthcare workers, have been identified and are being monitored.
The MV Hondius set sail from Argentina in late March. Authorities are conducting sanitation measures on the ship, and passengers have been isolated to minimize further spread of the virus. There are currently around 150 individuals on board, including four Canadian citizens. However, no Canadians have been reported affected.
Health Risks and Viral Impact
The hantavirus can cause severe cardiopulmonary illnesses, with a reported case fatality rate of up to 50%. Hospitalized patients may require supplemental oxygen or mechanical ventilation during treatment. WHO Director-General Dr. Tedros Adhanom Ghebreyesus indicated that the overall public health risk remains low, despite the current situation.
Evacuations and Future Precautions
Three patients suspected of having the hantavirus have been evacuated from the MV Hondius and are en route to the Netherlands for further medical care. The evacuation involved coordination between WHO and multiple national authorities. Additionally, Spain’s Health Ministry has agreed to assist with the ship’s docking and management amidst the outbreak.
As authorities continue to monitor the situation, they urge the public to remain cautious while acknowledging that direct human transmission is uncommon. Most hantavirus cases are typically associated with contact with infected rodents and their waste.
In summary, the detection of the Andes hantavirus strain on the MV Hondius underscores the need for vigilant health measures. Efforts are ongoing to safeguard the health of passengers and those in contact with the individuals affected by this virus.
