Has emerged the world's 40 drug-resistant swine influenza viruses, University of Hong Kong Li Ka-shing (related) such as Harvard University School of Medicine in conjunction with the United States to conduct the study.
(Roundup) (Sing Tao Daily reported) the number of pick-up in swine influenza infection, there are visits to Hong Kong virus, experts believe that Hong Kong may have entered the swine flu, the second wave, although the epidemic is expected to moderate, but found the world's emerging 200 Nianer were variants of swine influenza virus, lethal for children under ten or stronger, the virus will go into the lungs; Experts urge people to fight swine influenza vaccine as soon as possible, but also proposes that the Government will be free for children vaccination of swine influenza vaccine policy and consists of six extended to the age of ten or below for children.
Visit to the United States is Hong Kong's Research Hospital in St. Zhu De, Department of infectious diseases, virologists Weishi Bo (Webster), Professor said that the U.S. is now the second wave of swine influenza in the fall period, but since the outbreak of swine influenza throughout the country since there are eight million 16 children under the age of infection, 36000 were hospitalized, 540 children died from swine flu, compared with an annual average of only 80 children die from seasonal influenza, a difference of nearly seven times the number of deaths.
Weishi Bo also said that Norway discovered variant of swine flu, the global Nianer 200 cases have been found, because of its viral proteins, the regional variations in the H22, so that variants of swine influenza on children under ten or highly lethal, the virus can penetrate the lungs in patients with , resulting in two deaths in Norway, the deceased black lung, such as coke.
He was worried that the United States when the third wave of swine flu, would be led by a variant of swine influenza virus, when more children will be subject to attack, but also worried that swine influenza virus and up to five percent of the deadly H5N1 bird flu virus reshuffle, will be more lethal severe.
Weishi Bo added that the U.S. is now a trial drug Peramivir, intensive care for children with severe swine influenza treatment, the drug directly into the blood vessels, a considerable effect, but each time you use are subject to prior approval of the U.S. Centers for Disease Control and Prevention (CDC) approval.
Hong Kong people infected with swine flu, the number rebounded Wei Shibo that, there are likely to have entered the second wave of swine flu, it is estimated that the overall epidemic in other countries or regions are similar, are considered moderate.
As concerns the virus variants influence, he worried that children under ten or infections as severe as with the United States, so that Hong Kong free of charge for children under six plan to fight flu shot, might consider extending to the old, "even if the virus mutates, the vaccine and drugs are still effective. "
In addition, the global drug resistance has emerged 40 of swine influenza virus, in conjunction with the University of Hong Kong Li Ka Shing School of Medicine at Harvard University and other mathematical model of the relevant research shows that in an influenza pandemic, the early use of a single antiviral drugs, such as Tamiflu, infection rates of up to Qi Cheng.
However, if at an early stage (community population, lower than the percentage rate of infection 1:00), restraint and medication, only the use of Relenza or amantadine, or mix them and Tamiflu can reduce the resistance, and also would reduce the transmission rate less than 5 into 7.
Participated in the study of Hong Kong School of Public Health assistant professor of beard-kei said: "This response is the nature of the insurance, but the Government has implemented, is still considering a number of factors, it is necessary to see the public would accept."
