A hantavirus outbreak on the luxury cruise ship MV Hondius has raised fears of a potential global pandemic, but health officials urge calm. The virus has infected eight people so far, with five confirmed cases and three suspected. At least six individuals are hospitalized, including three British nationals, following possible exposure. Three deaths have been reported: a Dutch couple and a German citizen.
Authorities Trace Passengers After Fatal Flight
Authorities are urgently searching for seven British nationals who disembarked the ship before the outbreak was confirmed. Additionally, passengers and crew from a flight between Saint Helena and Johannesburg are being traced after a woman who was on board later died of hantavirus. The flight on April 25 carried 82 passengers and six crew members. The World Health Organisation (WHO) has raised concerns about possible human-to-human transmission, increasing the urgency of locating them.
What Is Hantavirus?
Hantaviruses are a family of rodent-borne viruses, with each strain linked to a specific host. Transmission occurs through contact with infected rodent droppings, saliva, urine, or nesting materials. Human-to-human transmission is extremely rare, though the Andes strain responsible for this outbreak has shown that capability in South America. The incubation period ranges from two days to eight weeks, typically two to four weeks.
Infection can lead to two main illnesses: Hantavirus Pulmonary Syndrome (HPS), which affects the lungs, and Hemorrhagic Fever with Renal Syndrome (HFRS), which affects the kidneys. Both can be fatal.
Symptoms to Watch For
Early symptoms resemble the flu and include headaches, dizziness, chills, and abdominal issues like diarrhea, vomiting, and nausea. As HPS progresses, patients may experience coughing and shortness of breath. HFRS symptoms include intense headaches, back and abdominal pain, fever, blurred vision, and later low blood pressure, shock, internal bleeding, and acute kidney failure. There is no cure, so monitoring symptoms after exposure is critical.
Should We Be Worried?
WHO Director-General Dr. Tedros Ghebreyesus acknowledged that more cases may emerge but stressed that the public health risk remains low. Infectious disease epidemiologist Maria van Kerkhove emphasized that this outbreak is not the start of a COVID-like pandemic, as hantavirus spreads very differently. Dr. Abdirahman Mahamud, WHO emergencies director, pointed to a similar outbreak in Argentina (2018-2019) with 34 cases, noting that member states have the experience to contain the virus. He stated, “We don’t anticipate a large epidemic.”
Health officials continue to monitor the situation, but for now, the threat of a global pandemic remains minimal.
