Killer bird flu ‘may be worse than SARS’
The avian flu has killed millions of chickens in South Korea, Vietnam and Japan, where officials have ordered mass culls to try to contain the outbreak. Hong Kong and Cambodia have banned poultry imports from countries affected by bird flu.
WHO says tests are being done to determine if the deaths of nine additional people in Vietnam are linked to the disease, but has stressed that there has been no person-to-person spread of the disease. Health officials attribute infections in humans to contact with the droppings of sick birds.
