Abstract

Bovine herpesvirus 1 (BoHV-1) is accountable for infectious bovine rhinotracheitis (IBR), a disease of major economic thrashing in the cattle industry globally. BHV-1 is a member of the genus Varicellovirus in the sub family Alphaherpesvirinae, belonging to the family Herpesviridae. The property of establishing a latent state in ganglionic neurons after infection allocates the BHV-1 virus to persist in the body and spread the disease from a latently infected carrier to a non-infected herd. The first report of BHV-1 infection was recorded as genital form of disease as infectious pustular vulvo-vaginitis (IPV) in cattle in 1841 in Germany. Viral association with this form of disease was confirmed in 1928; respiratory form (IBR) was observed in 1950s and in 1958 for the first time the virus was isolated successfully and classified in the family Herpesviridae. BHV-1 is currently widespread all over the world, and observed in USA, Canada, Zaire, Italy, Belgium, India, Japan, Taiwan and Turkey. The documented prevalence of BHV-1 is 83% in UK, 63%–86% in Eygpt, 43% in England, 36%–48% in Central and South America, 36% in China, 14%–60% in Africa and as restricted distribution in India. Among East and South Asian countries in Nepal, Sri Lanka, Korea, Bhutan and Bangladesh disease was not reported. BHV-1 virus has been detected in many states of India, like Uttar Pradesh, Uttarakhand, Haryana, Kerala, Punjab, Chhattisgarh, Gujarat, Maharashtra, Tamil Nadu, Orissa, Arunachal Pradesh, Nagaland and Karnataka with maximum prevalence in Uttar Pradesh and minimum in Himachal Pradesh. Considering the emerging nature of virus, latency, unusual rate of spread of the infection with economic aspects, the current scenario of BHV-1 in South and East Asian region is addressed to formulate a comprehensive control strategy involving thorough screening before international trading and restricting animal movements between different parts of world.
