8. Both HPAI and LPAI A virus outbreaks occur among poultry sporadically and pose serious challenges to poultry farmers across the Globe.

9. Biosecurity: Bio-security is of immense help to reduce disease hazards and improve health and productivity of birds.

a) Optimum and profitable poultry production can be achieved by reducing disease risk to minimum extent

b) Biosecurity is important to keep lethal, highly contagious diseases out of premises, example Newcastle disease, avian influenza, etc.

c) The points involved with day to day running of the site. Includes routine disinfection, control of visitors, source of stock, etc.

10. Be sure to use a disinfectant in the poultry farms which is active against most pathogens, effective in the presence of organic material and active under the local outdoor temperatures.
