Find out the origin of the deadly strain of H7N9

The H7N9 influenza virus strain has a combination of genes between East Asian wild birds and farmed chickens in Shanghai city, Zhejiang province and China's Jiangsu province , Xinhua leads the research results of the Key Laboratory. The source of microbiology and immunology of the Chinese Academy of Sciences said.

Accordingly, the Truong Giang River Delta (China) may be the place where the combined gene source is generated. It is the result of a combination of genes between wild birds moving from Europe to Asia with the gene for bird and duck flu viruses in the Yangtze River Delta region.

The study also said that genetic modification in H7N9 virus also causes H7N9 to infect humans and lead to high mortality rates.

Previously, Western experts had rejected the Chinese scientists' hypothesis that the H7N9 virus originated from wild birds.

38 people were infected, 10 died

While the origin and route of transmission of the deadly strain of H7N9 remains unclear, the number of deaths and new infections in China has not shown signs of stopping.

Until now, China had 38 people infected with H7N9 and 10 of them died.

Only from 17:00 on April 10 to 17:00 on April 11, China had 5 more positive cases detected for H7N9 and 1 of them died. In it, Shanghai has 3 more cases, Jiangsu has 2 more cases. Death is a patient in Shanghai.

China is still looking for ways to stop the spread of H7N9. Until now, Shanghai, where many unified schools are found, the government has suspended all purchases of birds and poultry while destroying all poultry found to have H7N9 virus.
