A 3-year-old boy in Vietnam has tested positive for the bird flu, doctors said in an article on www.TimesofIndia.com.

The patient from the Mekong delta province of Dong Thap was admitted to Ho Chi Minh City's Hospital for Tropical Diseases March 16, and on March 18, a test came back positive for the H5N1 strain, said Nguyen Van Chau, director of the city's health care department.

"The situation of the boy is getting worse," Chau said.

Another doctor, from the municipal Pasteur Institute, said the boy's sample will be tested again to confirm the infection.
