Abstract :

This paper examines the emergence of drift variants of low pathogenic avian influenza (LPAI) viruses with particular focus on their occurrence in India. Influenza viruses are dynamic and continuously evolving and variants emerge from the instability of these viruses due to their constant mutations through antigenic drift. The drift variants emerging from the LPAI viruses gradually acquire higher virulence, inflicting heavy mortality and severe economic losses. Control of avian influenza viruses and the drift variants through vaccination is a great challenge because of the rapid evolution of LPAI viruses due to the pressure of vaccination immunity. Therefore, periodic evaluation and updating of the vaccine strains is required to provide sufficient protection to birds against the drift variants of LPAI.
