WHAT IS HUNTA VIRUS

Hantaviruses are a family of viruses spread mainly by rodents and can cause varied disease syndromes in people worldwide.  Infection with any hantavirus can produce hantavirus disease in people. Hantaviruses in the Americas are known as “New World” hantaviruses and may cause hantavirus pulmonary syndrome (HPS). Other hantaviruses, known as “Old World” hantaviruses, are found mostly in Europe and Asia and may cause hemorrhagic fever with renal syndrome (HFRS).

Each hantavirus serotype has a specific rodent host species and is spread to people via aerosolized virus that is shed in urine, feces, and saliva, and less frequently by a bite from an infected host. The most important hantavirus in the United States that can cause HPS is the Sin Nombre virus, spread by the deer mouse.

In the United States, deer mice (along with cotton rats and rice rats in the southeastern states and the white-footed mouse in the Northeast) are reservoirs of the hantaviruses. The rodents shed the virus in their urine, droppings, and saliva. The virus is mainly transmitted to people when they breathe in air contaminated with the virus.

When fresh rodent urine, droppings, or nesting materials are stirred up, tiny droplets containing the virus get into the air. This process is known as “airborne transmission“.

HOW IT IS GENERATED

There are several other ways rodents may spread hantavirus to people:

• If a rodent with the virus bites someone, the virus may be spread to that person, but this type of transmission is rare.
• Scientists believe that people may be able to get the virus if they touch something that has been contaminated with rodent urine, droppings, or saliva, and then touch their nose or mouth.
• Scientists also suspect people can become sick if they eat food contaminated by urine, droppings, or saliva from an infected rodent.

The hantaviruses that cause human illness in the United States cannot be transmitted from one person to another. For example, you cannot get these viruses from touching or kissing a person who has HPS or from a health care worker who has treated someone with the disease.

In Chile and Argentina, rare cases of person-to-person transmission have occurred among close contacts of a person who was ill with a type of hantavirus called Andes virus.

PREVENTION

There isn’t a vaccine for hantavirus. Steps you can take to reduce your risk of HPS include:

• Stay away from places where rodents leave droppings
• Wear rubber gloves and a mask that covers your nose and face during exposure to mouse droppings
• Use disinfectant to sanitize areas containing mouse droppings so infected dust does not spread in the air
• Seal holes in and around your home so rodents cannot get in
• Trap rodents in and around your home to decrease the population
• Avoid leaving food out in your home and when camping
• Before entering spaces known to have rodents in them, air out the area
