The Caribbean Public Health Agency (CARPHA) says there is no need for concern over Hantavirus, noting that the risk of an outbreak in the region, or globally, remains low due to several key scientific factors.
Amid concern surrounding eight Hantavirus cases aboard the MV Hondius, regional health experts told journalists during a virtual media briefing on Monday that there was no need for alarm.
CARPHA Executive Director Lisa Indar explained that the outbreak linked to the cruise ship involves the Andes strain of the virus. She said that strain is found in rodents primarily in certain parts of South America. The strain is only capable of limited human-to-human transmission, and because the disease is typically transmitted through contact with infected rodents and/or their excrement, it is unlikely to develop into a pandemic.
“Based on evidence, the rodent species that maintains this virus in nature is not present in the Caribbean, and therefore there is is no documented established route of transmission in our region. This rare human-to-human transmission requires intimate or prolonged exposure.”
Dr Indar said, nonetheless, CARPHA continues to monitor the situation.
“There is no current antiviral treatment or vaccine. Care is supportive, including oxygen therapy and intensive monitoring. So CARPHA advises our member states and the public to remain vigilant but not alarmed. CARPHA’s Caribbean-tailored early warning surveillance and lab laboratory system mechanisms and network is actively monitoring the situation and can detect and respond when needed.”
She added that although the risk is low, the public can still take precautions.
“CARPHA encourages the public to always practise good hygiene including frequent handwashing, avoid close contact with people who are unwell. Take precautions in environments where rodents may be present. These measures are effective not only for hantavirus, but for a wide range of infectious diseases.”
The MV Hondius, a polar expedition cruise ship, left Argentina on April 1st with 175 passengers and crew on board, destined for the Canary Islands.
On April 11th, a passenger died from the virus after showing symptoms for five days.
As of May 11th, the World Health Organization has reported seven confirmed cases of the virus among passengers.
