Is There a Hantavirus Vaccine? Here’s What You Need to Know

If you’ve heard about the hantavirus, you may be wondering whether there’s a vaccine available. Hantavirus is a serious disease that’s caused by a virus carried by rodents, specifically deer mice, in North America. It can cause severe respiratory symptoms and even be fatal in some cases. Not knowing what’s true and what’s not about hantavirus can be cause for concern, so we’ve put together this article to help answer some common questions about hantavirus and whether or not there’s a vaccine.

What Is the Hantavirus?

The hantavirus is a virus that’s carried by rodents, which was first identified in the early 1990s. It’s primarily spread by breathing in the virus from the air. In North America, the deer mouse is the primary carrier of hantavirus, although other rodents such as the cotton rat, rice rat, and white-footed mouse have also tested positive for the virus. People can also get hantavirus by touching a surface or object contaminated with the virus and then touching their nose or mouth. The symptoms of hantavirus infection can include fever, muscle aches, fatigue, and difficulty breathing, which can be fatal if not treated promptly.

What Are the Symptoms of Hantavirus Infection?

The symptoms of hantavirus infection can appear anywhere from one to five weeks after exposure to the virus. The virus initially causes flu-like symptoms, such as fever, chills, muscle aches, and fatigue. Nausea, vomiting, and diarrhea may also occur. After about four to ten days, the person may experience more severe symptoms, such as shortness of breath and coughing. These symptoms can be a sign of severe infection, which can lead to meningitis and even death in some cases.

How Is Hantavirus Diagnosed?

Hantavirus infection is diagnosed with tests that detect the virus or antibodies to the virus in the blood. To collect a sample, a healthcare provider will take a blood sample from a vein in your arm or perform a lung biopsy.

Is There a Cure for Hantavirus?

Currently, there is no specific cure or vaccine for hantavirus. Treatment focuses on supportive care, such as oxygen therapy and mechanical support, to help the person recover from the severe respiratory symptoms caused by the infection. Antiviral medications may be used in some cases, but their effectiveness is not yet known.

Are There Any Steps I Can Take to Prevent Hantavirus?

There are several things you can do to reduce your risk of contracting hantavirus:

  • Seal up holes and gaps in buildings where rodents can enter
  • Keep food in sealed containers and dispose of garbage regularly
  • Reduce clutter and remove potential rodent hiding places
  • Avoid cleaning up rodent droppings or nests without proper ventilation and protective equipment

What Is the Outlook for People Who Contract Hantavirus?

People who contract hantavirus can have a range of outcomes, depending on the severity of their infection. Roughly half of patients infected with hantavirus in North America require hospitalization, and about a third of those who are hospitalized die. However, most people who become infected with hantavirus do not become seriously ill and recover fully.

Is There a Hantavirus Vaccine?

Currently, there is no vaccine for hantavirus. However, researchers continue to study the virus and are working on developing a vaccine. As of now, the best way to prevent hantavirus infection is to take precautions to avoid being exposed to the virus in the first place.

Conclusion

Hantavirus is a serious disease that can be fatal in some cases. Although there is no vaccine for hantavirus currently, there are things you can do to protect yourself from exposure to the virus, such as sealing up holes in buildings and reducing clutter. If you suspect that you may have been exposed to the virus, it’s important to seek medical care right away to receive appropriate treatment.
