How dangerous is hantavirus?

How Dangerous Is Hantavirus Infection? A suspected Hantavirus infection on a luxury cruise sailing the Atlantic Ocean has raised concerns. According to the World Health Organization, three people have died in the incident, one confirmed case has been reported, and five other suspected cases are under investigation. Its spread on the cruise ship, the MV Hondius, has raised questions about how dangerous this virus is and how it can be prevented.

What is Hanta virus?

Hantavirus is not a single virus, but rather a group of viruses found primarily in mammals like rodents that gnaw on food. It doesn't spread directly to humans; it occurs when dried particles of feces, urine, or saliva from infected rodents become airborne and are inhaled, making it the most common mode of transmission, according to the Centers for Disease Control and Prevention.

Thousands of people are affected

Thousands of people worldwide are affected by this virus every year. According to data from the National Institutes of Health, approximately 150,000 cases of hemorrhagic fever with renal syndrome are reported annually, with more than half of these cases occurring in China. In the United States, approximately 890 cases have been confirmed between 1993 and 2023. However, a strain of the virus, known as the Seoul virus, is found in many parts of the world.

What is the biggest challenge of this virus?

The biggest challenge with this virus is that there is no specific cure. Doctors typically treat patients based on their symptoms, which may require oxygen therapy, ventilation support, and even dialysis in severe cases. Many patients require ICU admission, especially when the infection rapidly affects the lungs.

When did this come into discussion?

According to the BBC, a recent case came to light in February 2025 when Betsy Arakawa, wife of Oscar-winning actor Gene Hackman, died from a respiratory illness linked to the Hantavirus. Investigations revealed rat nests around their home, increasing the risk of infection. Experts say the most effective way to prevent this virus is to stay away from rodents. Blocking rodent access at home or work, wearing masks and gloves while cleaning, and avoiding direct contact with dirt are essential.

Why is there a problem in cruise?

The risk of such infections increases in enclosed spaces like cruise ships because many people live together in a confined space. If an infection spreads, it becomes difficult to control it.
