The disease has not been reported from India.Epidemiology: The transmission of disease takes place through inhalation, drinking contaminated water and colostrum by young ones. The intrauterine transmission of the virus has also been observed.

Affected sheep straggles, head jerking with inspiration and nostrils are flared. There may be nasal discharge and cough.
Visna: Weakness of the hindleg and stumbling. Progressive weight loss and trembling of facial muscels and limbs is seen leading to paraplegia.Diagnosis: The disease is diagnosed histopathology. Enzyme immunoassay, agar gel diffusion and syncytial plaque reduction assays are used for detection of antibodies. Western blotting is used for confirmation of the disease.

Prevention and control: Slaughtering of sero-positive sheep is one of the approaches suggested for containing the infection. Dipping of sheep with acaricides and spraying in environment controls ticks.
