Health officials in Bangladesh have asked U-S scientists for help in identifying a virus that has killed at least 16 people in Bangladesh and sickened about 35 others in recent days.
Authorities say tissue and blood samples were sent to the U-S Centers for Disease Control, after three of five children admitted to the Dhaka Medical College Hospital died in the past three days.
Authorities say at least four children came from a village (Goalando) in central Bangladesh.
Officials say the patients -- most of them young boys -- suffer from headache, vomiting and high fever before lapsing int unconsciousness. Some also suffered from diarrhea.
Authorities have declined comment on whether the sickness could be the bird flu -- a severe and sometimes deadly respiratory virus thought to infect humans exposed to diseased chickens or their droppings.
Bird flu has already spread to seven Asian nations. But Bangladeshi authorities said today (Sunday) they have no reports of diseased poultry.
