Calls should not be underestimated with the risk of explosive epidemic variant of H5N1 in Hong Kong experts fear into the mainstream

Shenzhen men suffering from bird flu death is still unknown source of infection! Shenzhen CDC and Hong Kong Centre for Health Protection dead virus samples for testing, we found that strain is a genetic mutation 2.3.2.1 sublines highly pathogenic avian influenza virus, and infected wild birds in Hong Kong earlier the infection is similar to the suspect infected by contact with dead wild birds. Hong Kong microbiology expert with respect to the current bird flu drugs are still valid, but concerned that this new virus will be in the next six branches in Hong Kong and the Mainland to become mainstream, there is the risk of avian influenza outbreak, the public can not be taken lightly.


WASHINGTON
Avian influenza in Shenzhen year-old man died on Saturday, Shenzhen CDC and Hong Kong Centre for Health Protection expert on respiratory dead sample extract, the avian influenza H5N1 virus genome sequencing and bioinformatics analysis, the results found in samples of influenza A virus H5 gene is 2.3.2.1 sublines highly pathogenic avian influenza virus, and Hong Kong earlier infected dead birds are infected with bird flu virus is very similar.


CDC refers to human transmission is not deep


Shenzhen Center for Disease Control found by phylogenetic analysis, the strain of infection is transmitted directly from poultry Perfect Human; also said that The virus from southern China in five to ○ ○ 2.3.4 pedigree 六年 popular gene mutation of avian influenza virus but emphasized that this is a natural phenomenon, the virus is still transmitted directly from poultry to people, not from person to person transmission.

Shenzhen CDC microbiological laboratory technician Wu Chunli said the center is also on the analysis of drug-resistant virus, the results of virus rimantadine, King Kong song adamantane bromide and other drugs are still more sensitive to Tamiflu resistance is still in the study of them; also known as the current spread of avian flu has not increased the risk of calling for people not to panic. He added that currently the source of infection is from the dead birds, yet to determine the relevant departments.

Hong Kong University infection and infectious disease center director, said Ho Pak-leung, a detailed analysis of how the virus variants still, although the virus drugs Tamiflu and Relenza no resistance, but the mortality rate remains as high as 50 percent think the situation is serious, people not be taken lightly. Patients infected with the virus in this branch of Mainland China in the past with different avian influenza, Ho Pak-leung said that if this virus to become a new branch in the next six months, the mainstream of avian flu in Hong Kong and the Mainland, the risk of outbreaks have the opportunity to appear.

He said: "The new branch there, pay attention to whether the vaccine used in chickens to reduce the effectiveness of which should pay close attention, more speed in the laboratory analysis, especially in Vietnam, many farms are vaccinated and continue to infect this species causing the outbreak, this situation will occur in Hong Kong and the Mainland should pay close attention to this. "He also urged the public to handle and eat chicken, duck, to thoroughly clean and cook.

Infectious disease specialist Lo Wing-lok respect, not simply the deceased virus gene sequencing, which confirmed that the deceased may be caused by wild birds infected with bird flu, that this is a basic fallacy, questioned the Mainland authorities to divert attention. He further explained that bird flu is spread by the live poultry, wild birds rather than between the department is shirking its responsibility to the mainland is a "natural disaster", not to examine whether the problems in Shenzhen poultry, that the Government should consider widening the ban on live poultry Mainland and poultry products to cover the whole of Guangdong Province.
