Prevention and Control of Bunyavirus Diseases

Rift Valley Fever

Suggestions for prevention of this disease include policing the international movement of livestock and the screening of animal sera periodically.


Hantaan Virus--Hemorrhagic Fever with Renal Syndrome

As this disease is transmitted from mice to humans, rodent control is key to prevention in households.  However, there is a need for a vaccine because of the difficulty of controlling rodents in an agrarian setting.  Special precautions should be taken by laboratory personnel who handle rats.

Vaccine: Inactivated vaccine derived from suckling mouse brain was licensed for use in Korea in 1990.
Other research has shown that immunization with glycoproteins can elicit a neutralizing response.

Sin Nombre Virus--Hantavirus Pulmonary Syndrome

Possible prevention measures include:
1)  Education of the public regarding how to avoid contact with infectious material.
2)  Careful monitoring of rodent population density, either directly or through satellite photographs.
3)  Health advisories issued when such conditions are present.

No vaccine has been developed.
