Bird flu remains a threat: WHO http://www.thanhniennews.com/2010/Pages ... 14047.aspx
Bird flu outbreaks that have killed seven people in several countries so far this year show the virus remains a threat to humans, the World Health Organization (WHO) said on March 24.
â€œThe newly confirmed human and poultry cases of avian influenza this year are a reminder that the virus poses a real and continuous threat to human health,â€ the WHO said in a statement.
One danger is that bird flu, also known as H5N1, may mutate, warned Takeshia Sakai, the WHOâ€™s regional adviser for communicable diseases.
â€œThe influenza virus is unpredictable,â€ Sakai said. â€œThere is a constant risk that the H5N1 virus will combine with another strain of influenza.â€ --- continued at link above ---
