Hong Kong infectious disease expert said, the the Mainland first time h7n9 avian flu human cases of infection, a high probability of virus variants monitor cases of human infection may also occur in the future.
Shanghai and Anhui reported human infection h7n9 bird flu cases, two deaths in patients in critical condition, media reports said it was the first time human infection h7n9 virus. Big infection in Hong Kong and Hong Kong, and Director of the Centre for Infectious Diseases, Ho Pak-leung said, the past human infection with avian influenza type Mainland, mainly belonging to h5 category.
Ho Pak-leung: "So this is transmitted to humans are special varieties of avian flu virus is likely to show the place has begun to appear the epidemiological transition. Because human transmission of the virus causing death, so this kinds of viruses with low pathogenic h7n9 previously found in the gene level, what is the difference, it will not be involved in some completely different genes, which have led to infect humans, such information is quite critical. "
Ho Pak-leung also said that, the h7n9 virus may be lurking in some birds, but not enough to make these birds incidence or death, cases of human infection may also occur in the future.
Ho Pak-leung: "assumes that the birds, for example, duck and goose categories already Pu exists for it there and then transmitted to the human risk, if people in contact with birds, health is not good, the presence of the virus in birds have a chance to spread to humans, so it can not be ruled out that there will be sporadic cases of infection. "
As to whether a large number of dead pigs in Shanghai Huangpu River, Ho Pak-leung said there is not enough evidence base comment whether the two, but because of one of these cases, the pork traders, the relevant mainland authorities to collect dead pig samples, testing of avian influenza virus. http://www.kaixian.tv/R1/n1598418c11.shtml
