A new strain of swine flu resistant to drugs
Emerged from a new strain swine flu in Asia could adapt a genetic resistance to a real estate "Tamiflu" produced by company "Roche" and "Relenza" produced by "Glaxo Smith Kline" and drugs are the key users in the fight against the disease.
The researchers noted that more than 30% of the samples of swine flu infection, "H-1 n 1" from the north of Australia and more than 10% of the samples collected from Singapore during the first months of this year, slightly reduced sensitivity to drugs.
Did not show any significant decrease in sensitivity to the drug "administered parenterally", a drug against influenza in the process of experimentation from the production company "Biochrist."
And discovered the new strain also in other parts of Asia and the Pacific, according to the Cooperation Center for Reference and Research on Influenza in Melbourne, which the World Health Organization in the journal "Aorossrfelians."
Although this genetic mutation may monitor before in a small number of cases of seasonal influenza and other bird flu "virus 5 The 1", but it did not register by the cases of swine flu, "H-1 n 1."
And discovered swine flu virus, "HP 1 The 1" in Mexico and the United States in March 2009 and quickly spread across the world.
The WHO believes that about 18 450 people were killed by the virus to August, many of them pregnant women and young people. The organization also announced the elimination of the virus in August.
Virus did not go away in any case include seasonal influenza vaccines provided through the world against the anti-"H-1 n 1." The few companies to produce influenza vaccines, including "Glaxo Smith" and "Sanofi" and "Novartis".
Expectations occurs when the mutation
There are many possibilities that can be expected to occur with a mutation, namely:
- The virus may become fiercer and fiercer, causing him a lot of complications and mortality in the second wave in the winter, as happened in the epidemic of 1918 and 1919, as well as the 1957 pandemic.
- There is a possibility of a mutation through the merger of each of the influenza virus epidemic "swine" with the bird flu virus, which has become endemic in Egypt.
- The virus may become more resistant to the drug "Tamiflu", causing problems in the treatment and control of the infected cases, has less efficacy of the vaccine factory towards him.
- There is a possibility to happen this mutation so that affects new objects, such as dogs and cats, as happened in the case of two dogs in China were virus isolation each of the 52 dogs infected with the flu, as well as the cat home in the state, "Iowa" in the United States, which has been confirmed infected with HIV, "H-1 n 1. "
- Perhaps a simple mutation happens to the virus does not lead to change the level of ferocity and virulence of the virus, would remain on the same level at which it is now, as happened in the second wave in the epidemic in 1968.
The experts also said that despite the high rate of injuries among school students in recent times, the proportion of deaths among them very few, and that pregnancy and HIV and chronic diseases and obesity of the most important risk factors that should be given "Tamiflu" in the beginning of the infection without waiting for analysis or delayed in the diagnosis, and of course should eat a preventive vaccine against swine flu, "H-1 n 1."
