How does bluetongue virus spread?

Bluetongue virus is spread by insects called biting midges (Culicoides spp.). (vector). Other biting insects, such as ticks or sheep keds, may also transfer the virus. Bluetongue is not contagious and is not spread by contact between animals.

Is bluetongue transmitted to humans?

Bluetongue disease is a non-contagious, insect-borne, viral disease that affects domestic and wild ruminants, mainly sheep and sometimes cattle, goats, buffalo, deer, dromedaries, llamas and antelope. Humans aren’t affected, nor are animal products or meat.

Is there a cure for bluetongue?

No satisfactory medical treatment has been found for animals with blue tongue. Generally, with proper care, most animals recover naturally within 14 days, although severely affected animals may recover more slowly. Isolate affected animals in a shaded area with palatable feed and fresh water.

How is the Bluetongue virus transmitted from person to person?

Bluetongue is an arthropod-borne non-contagious infectious disease of domestic and wild non-African ruminants. Under field conditions, the causative agent, bluetongue virus (BTV), is typically transmitted by Culicoides spp. insects (biting midges) following a bite to consume a blood meal from susceptible animals.

What kind of animals are infected with Bluetongue disease?

Bluetongue disease is a noncontagious, insect-borne, viral disease of ruminants, mainly sheep and less frequently cattle, goats, buffalo, deer, dromedaries, and antelope. It is caused by Bluetongue virus (BTV). The virus is transmitted by the midges Culicoides imicola, Culicoides variipennis, and other culicoids.

How is Bluetongue virus transmitted from sheep to goats?

Oral transmission of bluetongue virus has been demonstrated in colostrum, and experimentally via cultured viruses or urine from an experimentally infected sheep. Serotype 26 nucleic acids were found at low levels in nasal and ocular secretions of goats, and this virus was isolated from ocular swabs.

What happens to the BTV protein in bluetongue disease?

The low pH within the endosome then triggers BTV’s membrane penetration protein VP5 to undergo a conformational change that disrupts the endosomal membrane.
