Currently, no epidemiological association between the three cases. So far, three cases of patients diagnosed with a specific source of infection is not yet clear. In addition, 3 cases of 88 close contacts were not unusual.
Observe the recent national influenza activity levels were abnormally elevated
Influenza is an acute respiratory infection caused by the influenza virus. The influenza virus can be divided into A (A), (B), C III (C). Influenza can be divided according to the characteristics of the influenza virus HxNx 135 subtypes, the H7N9 subtype of avian influenza virus is one of them, the past is only found between poultry found no extraordinary circumstances of infection.
According to the the China CDC report found no recent nationwide influenza activity level is abnormally elevated.
Experts believe that, according to who is in close contact with medical observation, the virus has not prompted a strong human-to-human transmission.
To cope no vaccine; avoid contact with the disease (dead) livestock
Experts suggest that the event of fever, cough and other symptoms of acute respiratory infections, especially high fever, breathing difficulties, you should seek immediate medical attention. Maintaining wash their hands, cover nose and mouth when coughing or sneezing and other personal hygiene habits, can effectively prevent the transmission of influenza and other respiratory diseases. Should also avoid contact and edible disease (dead), poultry, livestock.

At home and abroad there is no vaccine against the H7N9 avian influenza virus.
Patients in early March death, why is published in the March 31 outbreak
On March 31, the National Health and Family Planning Commission in respect of human infection with the H7N9 avian flu, the question-and-answer.
Q: Shanghai a two family members of patients diagnosed with severe pneumonia occurred, whether there is an association?
A: February 20-25, in a hospital in Shanghai has treated three people suffering from severe pneumonia, surnamed Li and his son, and two people died. Mr Lee, his father was diagnosed with the H7N9 avian influenza virus infection, the diagnosis of two patients in progress. 3 patients the incidence of the family association, pending further investigation. In addition, Shanghai, Anhui diagnosed patients of all close contacts were not found in similar cases.
Q: two cases diagnosed patients died in early March, why is published in the March 31 outbreak?
A: The people infected with the H7N9 avian influenza virus, is the world's first discovery of a new subtype of influenza virus, has not been included in our statutory report infectious disease monitoring and reporting system.
Medical and health institutions in Shanghai found that the above-mentioned cases, in a timely manner to carry out the relevant laboratory screening, has ruled out the infected with seasonal H1N1 and H3N2 influenza, H1N1 flu, people infected with the highly pathogenic avian influenza (H5N1) and SARS, new Coronavirus possible. In further testing, the Shanghai Public Health Clinical Center on March 22 found that patients may be infected with the H7 influenza, after specimens were sent to the China Disease Prevention and Control Center.On the afternoon of March 29, the Chinese Center for Disease Control three H7N9 avian influenza virus isolated from the submission of cases specimens. National Health and Family Planning Organization experts further verification, according to laboratory test results, combined with the clinical manifestations, epidemiological data to conduct a comprehensive analysis to determine the patients with human cases of infection with the H7N9 avian flu virus.National Health and Family Planning Commission, in accordance with the law to the public on March 31.
Q: H7N9 virus and past H1N1, H5N1 and other seasonal influenza cases compared to its virulence and infectious?
A: As found only three cases of human infection with the H7N9 avian flu virus confirmed cases of the virus, due to disease is very limited research data, experts are of the virulence of the virus and the human ability to spread further judgment.
Q: If the infection early symptoms seek immediate medical attention if you can get effective treatment?
A: The gene sequence analysis showed that the drug-sensitive virus neuraminidase inhibitor class of anti-influenza virus. Experience other type influenza antiviral treatment after the onset of the early use of the neuraminidase inhibitor class of anti-influenza virus drugs may be effective remains to be seen, but the means of specific treatment of newly discovered human H7N9 avian influenza virus infection research.
HxNx virus family
Influenza can be divided according to the characteristics of the influenza virus HxNx 135 subtypes except H7N9, brought to mankind troubled, there are several "members."
The H1N1H1N1 1918 influenza virus has triggered large outbreak. Beginning in 2009, the new influenza A (H1N1) pandemic on a global scale.

H2N2 virus disappeared in 1968 has been caused over 100 million deaths in the world.
H3N2 influenza A (H3N2) influenza virus outbreak in Hong Kong in 1968, and subsequently extended to the world, known as the "Hong Kong flu". The latest outbreak, an outbreak of H3N2 seasonal flu early 2013, several states in the eastern United States.
H5N1H5N1 for highly pathogenic avian influenza virus. Avian influenza virus, H5, H7, H9 can be transmitted to humans, which H5 highly pathogenic, H5N1 is the report of the statutory provisions in the new Ministry of Health Communicable Disease Prevention Act infectious diseases, also known as human infection of highly pathogenic avian influenza .
