Hanoi (AsiaNews/Agencies) New cases of infection have been confirmed in Vietnam, Indonesia and Thailand. Vietnamese researchers warn that the virus has mutated into a strain more perilous to man.
Vietnam. Two new cases of infection were confirmed today. One was a student taken to hospital after eating a hen's egg and the other was a 78-year-old woman who died on Friday 11 November from pneumonia in the central province of Quang Binh. The Agriculture Minister said the virus has now spread to 10 of the 64 provinces: last weekend more than 1000 geese and hens died in the northern port of Haiphong. The culling of all birds in Ninh Binh and the northern province of Hung Yen was ordered. The Hanoi and Ho Chi Minh city authorities have said it is forbidden to have live poultry farms in the cities. Birds found will be culled.
Cao Bao Van, head of the Molecule Biology Department, said yesterday the H5N1 virus found in a patient, who later died, had mutated in a form "which allows it to reproduce in the tissue of mammals and become very contagious". This virus appears immune also to Tamiflu.
China. Roy Wadia, China spokesman for the World Health Organisation, confirmed that they are waiting for the outcome of testing on a peasant, a woman, from Liaoning, feared infected. There has been a new outbreak of infection in the central province of Hubei, with 2,500 dead birds and 30,000 culled. The Agriculture Ministry published an open letter to 800 million farmers on the ministry website, to explain that the bird flu scenario is "very serious" and to urge them to take more precautions and to be more watchful.

President Susilo Bambang Yudhoyono admitted that two more people died of the disease (a 13-year-old girl who died on 8 November and a 20-year-old woman who died on 12 November) in Jakarta's Sulianti Saroso hospital. This beings the country's death toll to seven. "Special attention" for the populated areas of the capital has been announced; "11 confirmed cases of infection, seven of them now dead" came from there. A 16-year-old girl admitted to hospital on Friday 11 November was also confirmed to be infected. Testing was undertaken in Hong Kong labs.
