Puumala

Puumala is a virus that belongs to the Hantavirus genus of the Bunyaviridae family. It is named after the municipality of Puumala, Finland where it was first identified. The virus is primarily carried by the bank vole (Myodes glareolus), a common rodent in Europe. Humans can contract the virus through contact with the urine, feces, or saliva of infected voles.

Transmission and Symptoms

Puumala virus is transmitted to humans through inhalation of aerosolized virus particles from the excreta of infected voles. The virus is not known to be transmitted from person to person.

The primary disease caused by Puumala virus is Nephropathia epidemica, a mild form of Hantavirus cardiopulmonary syndrome. Symptoms include fever, headache, backache, abdominal pain, and renal dysfunction. Severe cases can lead to hemorrhagic fever with renal syndrome (HFRS).

Diagnosis and Treatment

Diagnosis of Puumala virus infection is typically confirmed through serological tests, such as ELISA, that detect specific antibodies in the patient's blood.

There is no specific antiviral treatment for Puumala virus infection. Treatment is supportive and may include hospitalization, oxygen therapy, fluid replacement, and dialysis in severe cases.

Prevention

Prevention of Puumala virus infection involves avoiding contact with voles and their excreta. This can be achieved through rodent control measures and by taking precautions when cleaning areas potentially contaminated by rodent excreta.
