Three British nationals have been diagnosed with suspected Hantavirus in connection with an outbreak of the disease aboard the MV Hondius cruise ship. The ship is currently docked at the remote Atlantic island of Tristan da Cunha, and the two other cases have been medically evacuated. The third remains aboard the ship.

According to the World Health Organisation (WHO), eight cases have been reported so far, and three have died. Five of the eight cases have been confirmed as Hantavirus. Despite the seriousness of the virus, the public risk is very low according to the WHO. However, experts are urging people to be aware of the symptoms of the virus and how to avoid catching it.

Declan Lismore, Superintendent Pharmacist at Chemist4U said: “Hantavirus can be serious to those that are exposed and you should be aware of the symptoms and how to take preventative action to avoid contracting it.

“Most people won’t encounter Hantavirus in everyday life but given the recent outbreak on board a cruise ship it is important that people understand the signs and symptoms of Hantavirus and how it is transmitted.”

Hantavirus is a group of viruses carried by rodents that can cause serious disease in people. Usually, it’s transmitted via the inhalation of particles contaminated with rodent urine, feces or saliva.

Declan said: “However, the rare strain of Hantavirus linked to recent cases and fatalities has been known to spread between people in close contact. While the risk to the public remains low and confirmed cases are isolated, the risk of human-to-human transmission means you should be aware of the symptoms.”

Early symptoms of Hantavirus include:

• Fever
• Muscle aches
• Fatigue
• Headaches
• Nausea or abdominal pain

The disease can progress in severity and cause Hantavirus Pulmonary Symptoms and Hemorrhagic Fever with Renal Syndrome. These can cause a persistent cough and shortness of breath.

Declan said: “At present, the outbreak of Hantavirus is isolated and it is important not to panic, however, due to the severity of these illnesses, it is crucial that you seek out medical assistance quickly if you experience any symptoms or if you come into contact with someone that tests positive for Hantavirus.”
