Within hours of the first positive cases of avian influenza, the State Government on Monday put all districts on alert. Wildlife officials of Chilika and Bhitarkanika, the two major birding sites, were asked to enhance surveillance and monitor their avian population constantly.

Governments should invest in vaccines for all strains of influenza virus that exist in the animal kingdom as an insurance policy in case of an outbreak in humans, the incoming chief scientist at the World Health Organization said on Monday (Feb. 20). Countries ranging from the United States and Britain to France and Japan have suffered record losses of poultry in outbreaks of avian flu in the past year. The recent spread to mammals of H5N1 - commonly known as bird flu - needed to be monitored, but the risk to humans remained low, the WHO said earlier this month. Incoming WHO chief scientist Jeremy Farrar said he would like to see the pharmaceutical industry at least conduct some clinical trials for all influenza strains such that the world would not have to start from scratch to initiate global manufacturing should the need arise. "My concern that we're in slow motion watching something which may never happen," he added in a media briefing. "But if it were to happen, would we look back on what we're doing at the moment and say, why didn't we do more?"

Anti-influenza measures applicable to human as well as avian forms are described including the recent epidemic of swine flu. Resistance can develop against neuraminidase inhibitors although it is less than that with adamantanes. Considering these problems, there is need for a more effective agent. Investigations into alternative anti-influenza target will probably expand in the coming years. These include the development of mechanisms to inhibit fusion between the virus envelope and the cell membrane.

Biotechnology has potential applications in the management of several animal diseases such as foot-and-mouth disease, classical swine fever, avian flu and bovine spongiform encephalopathy. The most important biotechnology-based products consist of vaccines, particularly genetically engineered or DNA vaccines.

Influenza, commonly shortened to "flu" is an extremely contagious respiratory illness caused by influenza A or B viruses. Flu appears most frequently in winter and early spring.
