India has not reported a confirmed hantavirus outbreak and risk to the general public remains low as of May 2026 , but that does not mean the risk can be ignored. Rodent infestations, poor sanitation, and exposure to contaminated spaces can create conditions where the virus may spread. That is why it helps to know what hantavirus is, how it spreads, and the steps you can take to stay protected.
What Is Hantavirus?
Hantavirus is caused by a group of viruses that belong to the Hantaviridae family. These viruses are carried by certain rodents, particularly rats and mice, and can affect humans who come into contact with them. There are two main types of illness it leads to, and they affect different organ systems.
The infection doesn’t spread from person to person in most cases (outside of one specific strain found in South America
Types of Hantavirus Infections
There are two main forms of Hantavirus infections you should know about:
- Hantavirus Pulmonary Syndrome (HPS): This is more common in the Americas and affects the lungs. It can progress quickly and, if not treated in time, can become life-threatening.
- Haemorrhagic Fever with Renal Syndrome (HFRS): Found more in Europe and Asia, this form primarily affects the kidneys and can also be severe.
Causes of Hantavirus
Hantavirus is caused bydirect or indirect contact with rodents that carry the virus. Here’s how exposure typically happens:
- Contact with rodent urine, droppings, or saliva
- Being bitten by an infected rodent (less common)
- Touching your mouth, eyes, or nose after contact with contaminated surface
Symptoms & Treatment of Hantavirus
The first symptoms of hantavirus tend to show up one to eight weeks after exposure and can easily be confused with the flu. This is what makes it easy to miss early on.
If you are wondering what the signs and symptoms of hantavirus are, here’s what to look out for:
- Fatigue, fever, and muscle aches (particularly in the thighs, hips, and back)
- Headaches and dizziness
- Chills and gastrointestinal issues like nausea, vomiting, or stomach pain
As the illness progresses, particularly in hantavirus cardiopulmonary syndrome (HCPS), hantavirus symptoms in later stages can include shortness of breath, coughing, and fluid building up in the lungs. This is the critical phase and requires immediate hospitalisation.
How to Prevent Hantavirus?
Here’s what you can do to lower your risk:
- Seal up cracks or holes in your home that rodents could use to get in.
- Store food in airtight containers and keep spaces clean.
- Wear gloves and a mask when cleaning dusty or enclosed spaces that might have rodent activity.
- Ventilate spaces before cleaning them, and wet-mop instead of sweeping to avoid raising dust.
- Dispose of rodent droppings carefully and safely.
Importance of Buying Health Insurance
A sudden illness can require anything from a short period of rest to more intensive medical attention, depending on its severity. In such situations, having a comprehensive health insurance policy can help you manage medical expenses more comfortably.
Depending on the terms and conditions of your policy, it may cover hospitalisation costs, diagnostic tests at an additional premium, and other medical expenses so that you’re not caught off guard when a health emergency hits.
Conclusion
Hantavirus may not be making headlines right now, but the being aware of conditions for exposure, how it spreads, what to watch for, and how to protect yourself is important. A reliable health insurance policy can help cover medical expenses and may help provide financial support.
