On Thursday, four Asian countries and Denmark confirmed the presence of the deadly H5N1 virus. It appeared in tests in Afghanistan, India and Myanmar and the flu might have killed turkeys in Israel as well. In India, more than 70,000 birds have been exterminated in order to try to stop the spread; also, hundreds of people were tested for fever. The latest European country affected, Denmark, found the H5N1 strain in a wild buzzard found south of Copenhagen. Authorities have ordered that poultry and eggs must not be transported out of the area, while poultry needs to be kept indoors, away from wild birds. This piece of news comes a day after Swedish authorities have confirmed two wild ducks infected on the country's east coast. In Serbia, a teenager infected with bird flu was put in isolation, after developing high fever. Swiss drug maker Roche announced an increase in the production of Tamiflu by about 30%. Roche also agreed on deals with external producers, increasing its production to a total of 400 million by the end of the year. The drug is one of the most effective methods of treating people infected with H5N1. Bird flu spread alarmingly fast in the past few weeks, leaving impoverished nations such as Afghanistan and Myanmar asking for international help. No human cases have been confirmed so far in India, Afghanistan, Myanmar or Malaysia. In Myanmar, strict measures were imposed by authorities, including the slaughter of more than 5,000 birds and the temporary closing of poultry markets. International authorities fear that Afghanistan, which has a weak health system, will have to make a great effort in order to contain an outbreak. Agriculture officials stated that they do not even have protective suits to wear when dealing with infected birds.
