Hantavirus Treatment and Prognosis

People with hantavirus are admitted to the intensive care unit (ICU) where treatments include: oxygen, breathing tube or breathing machine in severe cases, and administration of Ribavirin to treat kidney-related problems and reduce the risk of death.

There is no effective treatment for hantavirus infection in the lungs.

Hantavirus is a serious infection that can rapidly get worse, resulting in lung failure and death.

Possible complications include kidney failure, heart failure, and lung failure.

Despite aggressive treatment, at least half of people with hantavirus in their lungs die.

Current Hantavirus Outbreak Deaths

At least eight people have been infected with Hantavirus Pulmonary Syndrome, and three people have died. As the United States CDC has assured the public, this disease has a self-limiting nature, since no cases of transmission between humans have ever been found.
