According to the statistics of health departments in various provinces and cities, as of May 29th, 20 13 10, 37 people died and 76 people recovered, which were distributed in Beijing (2 cases) and Shanghai (33 cases died/kloc-0). 2 cases died), Shandong (2 cases), Henan (4 cases), Jiangxi (5 cases, death 1 case), Fujian (5 cases), Hunan (2 cases), Taiwan Province (1 case) * *1case.
2. Can 2．H7N9 avian influenza virus spread from person to person?
It has not been confirmed that the virus has the ability of human-to-human transmission.
3. What is the source of infection of this case of human infection with H7N9 avian influenza?
The human infected H7N9 influenza virus belongs to avian influenza virus in virus biology. Most of the influenza viruses found in the world infected with H7 subtype also came from poultry, but up to now, the specific source of infection of the confirmed cases is still unclear.
4. What is the incidence of infection among close contacts of the case?
No similar cases have been found among all close contacts of the confirmed cases at present.
5. Is there a vaccine against H7N9 avian influenza virus at present?
At present, there is no vaccine against H7N9 avian influenza virus, and the National Health and Family Planning Commission is organizing vaccine research on H7N9 avian influenza. Generally, it takes 6-8 months to develop a vaccine, but it may take longer to develop a new bird flu virus.
6. What are the current treatments?
Gene sequence analysis showed that the virus was sensitive to neuraminidase inhibitors as anti-influenza drugs. According to the experience of antiviral treatment of other types of influenza, it may be effective to use neuraminidase inhibitors as anti-influenza drugs in the early stage after the onset, but the specific treatment for the newly discovered H7N9 avian influenza virus infection still needs to be observed and studied.
If you have cold symptoms, especially patients who have been exposed to birds, you should seek medical advice in time, and strive for early detection, early diagnosis and early treatment. Patients with mild colds are usually confined to the upper respiratory tract and can generally heal themselves; For those who have pneumonia symptoms, they should go to medical institutions in time and be hospitalized in time; Intensive care should be carried out for those with severe degree.
7. Is there a high risk of public infection with H7N9 avian influenza virus?
At present, only a few cases have been found in local areas, and the close contacts of the cases have not found any subsequent cases through medical observation. According to the limited evidence at present, the risk of public infection with the virus is low.
8. Is the risk of medical staff being infected with H7N9 avian influenza virus high?
At present, there is no definitive evidence of human-to-human transmission of H7N9, and no infected cases have been found among the medical staff in the three confirmed cases. However, because medical staff have more opportunities to contact patients with infectious diseases than the general public, it is suggested that medical staff take necessary protective measures during the diagnosis and treatment of patients. When accepting suspected or confirmed cases of H7N9 avian influenza, effective protective measures should be taken, namely standard prevention, droplet transmission prevention and contact prevention.
9. At present, what is the diagnosis and treatment ability of medical institutions around the country for this new disease, H7N9 avian influenza?
After the case appeared, the National Health and Family Planning Commission quickly organized experts to formulate a diagnosis and treatment plan for human infection with H7N9 avian influenza and guidelines for hospital infection prevention and control. On April 2, the national provincial and some prefecture-level medical staff were trained in diagnosis and treatment techniques to standardize and guide the clinical frontline to do a good job in case discovery, diagnosis and treatment.
10. What is the detection ability of avian influenza virus in China at present?
At present, the detection ability of avian influenza virus in China has been greatly improved, and the detection reagents have been distributed in 3 1 province.
1 1. What actions have been taken by relevant departments in China at present?
After the case appeared, the local health department attached great importance to it, and timely adopted patient treatment, epidemiological investigation, specimen collection and inspection, medical observation of close contacts, and strengthened the monitoring of unexplained pneumonia cases.
The National Health and Family Planning Commission attached great importance to the epidemic situation. After receiving the report of severe unexplained pneumonia, it immediately dispatched an expert working group to guide the local people to carry out the treatment and investigation of patients, held a multi-sectoral chamber of commerce, analyzed and judged the nature of the epidemic, and arranged and deployed relevant investigations, prevention and control, and response preparations. The National Health and Family Planning Commission set up a leading group for prevention and control, and quickly organized experts. On April 3, it issued three professional technical plans, namely, H7N9 avian influenza epidemic prevention and control plan, diagnosis and treatment plan, and technical guide for hospital infection prevention and control, and issued a notice on strengthening the prevention and control of human infection with H7N9 avian influenza, requiring local health administrative departments to attach great importance to it, adhere to scientific prevention and control according to law, strengthen medical treatment, monitoring and laboratory testing, and do a good job in information reporting and publishing.
After receiving the case report and the samples submitted for inspection, the National Center for Disease Control and Prevention (CDC) promptly carried out the epidemic risk judgment and laboratory testing research, made the etiological diagnosis of the cases in a short time, discovered and confirmed the human infection cases caused by the new H7N9 avian influenza virus for the first time in the world, and made an in-depth analysis of the characteristics of the new virus.
