According to Reuters, a detailed analysis of the case of this 35-year-old patient, scientists from the Zhejiang Province Center for Disease Control and Prevention said that the case is different from the previous cases because of this case. serious. The disease occurs in a young patient and does not have direct contact with live poultry before becoming ill.

According to the researchers, this case and a new case have just been confirmed a few days ago on a 67-year-old man living in Jiaxing City, also in Zhejiang Province, doing the transportation and selling work. poultry, suggesting that the virus continues to exist on poultry throughout the summer.

In general, flu experts around the world also constantly warn that the number of cases of the disease has decreased markedly in the last few months does not mean that the risk of H7N9 bird flu has passed.

The first scientific analysis of human-to-human transmission of the H7N9 virus in August provided solid evidence of the possible spread of the virus on humans and thus, potentially causing a great pandemic. Another study published in August also found that many other H7 strains exist on poultry and threaten to "further outbreaks".

Researchers said that, based on China's experience this spring, when there were 30 cases in March and peaked with 88 cases in April, the best method now is to maintain and increase. Intensive monitoring of humans and animals to ensure that new H7N9 infections are detected and diagnosed quickly. At the same time, a live poultry market cleaning and closing campaign could be a way to reduce the possibility of infection and deaths from the virus.

The H7N9 virus that first appeared on humans earlier this year killed 45 of about 135 cases, before signs of settling down during the summer.

On October 26, China National Influenza Prevention Center announced that it has successfully prepared a vaccine against H7N9 bird flu. This is the first flu vaccine developed successfully by Chinese scientists.

According to the World Health Organization, the influenza strain H7N9 can easily be spread from poultry to humans at a faster rate than other avian influenza viruses, including the H5N1 virus that once killed more than 250,000 people. Around the world. Therefore, scientists assessing the anti-influenza H7N9 vaccine will play an important role in controlling and preventing this dangerous infectious disease.
