Bird flu crisis mounts as official plays down fears
The 15-year-old boy in Vietnam was in hospital with fever, coughing and shortness of breath in northern Thanh Hoa province, where doctors said it was unclear how he was infected.
Many of the 20 people killed by bird flu in Asia have come from poultry farming families or otherwise had contact with birds sickened by the outbreak, which was first reported in December in South Korea and now spans across 10 countries.
