H7N9, China: Zhejiang patient?s virus genome sequenced, not mutated

BEIJING, Hangzhou, October 18 2013 (trainee reporter Zhu Xiaoyan) on the 18th, the reporter learned from the Zhejiang Provincial Center for Disease Control, on the 14th of human infection with H7N9 avian influenza in Shaoxing patients with viral gene sequencing revealed that the virus did not change significantly variation.

October 14, Shaoxing, Zhejiang Provincial Health Department diagnosed cases of human infection of an avian influenza H7N9 confirmed cases, the Zhejiang Center for Disease Control overnight patient throat swab specimens for gene amplification in a day and a half to complete the sequencing of the virus has been The complete genome sequence.

Zhejiang CDC microbial detection bureau chief expert Lu Yi-yu said that the analysis showed that the virus genome sequence with the first half of the high degree of similarity, there was no significant variation, and the submission of international genome sequence databases.

Lu Yi-yu said: "As autumn and winter flu virus itself is the active season, is expected in the next period of time, does not exclude the H7N9 avian influenza may occur in order to disseminate the state, while the ordinary seasonal flu incidence level will show an upward trend."

Lu Yi-yu recommend people not to panic, once the fever, cough and other symptoms of acute respiratory infection should seek medical treatment as soon as possible to improve the body immunity.

He said: "H7N9 avian influenza virus resistance is not strong on the outside, at 100 degrees Celsius environment, two minutes can be eliminated, it can be said of alcohol, heat sensitive."

Lu Yi-yu told reporters, do not rule out limited human to human transmission, even contagious, infection rate is very low. (End)

Zhejiang CDC: H7N9 virus mutation did not change significantly

Release date :2013 -10-19 07:51　　

Patients Shaoxing provincial CDC viral gene sequencing results showed that:

H7N9 virus mutation did not change significantly
　　
Heat and alcohol can destroy it
　　
Experts advise: winter, flu, prevention is very important, more windows more exercise, the best hot cooked poultry
　　
October 14, the province working in Shaoxing Liu confirmed H7N9 avian influenza virus infection in a critical condition.
　　
After a lapse of a summer, H7N9 avian influenza re-enter Chekiangese vision, we are very concerned about the Liu virus infection, there is no mutation? There will not be as half as many people infected?
　　
Provincial CDC for patients with viral samples overnight and a half days time to complete the sequencing of the virus obtained whole genome sequences. The results show that the first half of this year the virus genome sequence similarity is high, no obvious variation. The virus genome sequence was submitted on October 16 international databases.
　　
No variation
　　
Public need not panic
　　
Health chief expert microbiological testing Lu Yi-yu said that sequencing showed this spring with the outbreak of H7N9 avian influenza than 99% homology, with no variation.
　　
What does this mean? Lu Yi-yu said, it means that the spring will not be the same as SARS fears of people infected person's situation. Most recently, including the director of State Key Laboratory for Diagnosis and Treatment of Infectious Diseases Academician Li Lanjuan including many national experts, are published in the international journal H7N9 avian flu virus research. Experts believe that the presence of the virus from person to person with limited capacity, this spring outbreak of H7N9 bird flu, no cases of human to human transmission occurred.
　　
Provincial CDC advised people not to panic, once the fever, cough and other symptoms of acute respiratory infection, especially high fever, difficulty breathing, should wear a mask, doctor as soon as possible, and remember to tell the doctor whether the contact with poultry before the onset of history.
　　
Avian influenza virus
　　
Fear high
　　
Provincial CDC experts stressed that as the winter flu virus itself is the active season, is expected in the next period of time, does not exclude the H7N9 avian influenza may occur in order to disseminate the state, while the ordinary seasonal flu will show a rising incidence level Trends.
　　
Therefore, to do the appropriate protective measures influenza necessary.

Include: indoor regular window ventilation to keep air fresh; fewer trips to crowded public places, to avoid the flu virus; enhance outdoor physical activity, improve the body resistance to disease; injectable flu vaccine every year 10 to 11 months is the injectable flu vaccine best time, especially the elderly, children, serious chronic diseases, and immunocompromised patients who may be in close contact; wash their hands with soap or hand sanitizer and wash with running water, no dirty towels towels, hand contact with respiratory secretions later (eg after sneezing) should immediately wash their hands; sneezing or a handkerchief or tissue when you cough cover your nose and mouth to prevent droplet contamination to others.
　　
While hot enough influenza virus inactivated cases, that is to lose infection, morbidity and reproductive capacity, including H7N9 avian influenza virus resistance is not strong on the outside, at 100 ℃ environment, two minutes will be eliminated; 60 ℃ environment, elimination half-hour. For poultry and other birds for food, as long as from the formal channels of purchase of poultry, cooked at high temperature processing, quarantine is safe, safe to eat.
　　
A recent experimental results showed that 70% concentration of alcohol in 15 seconds the H7N9 avian influenza virus can be inactivated.
