In January, a family Xiaoshan District, Hangzhou clusters of cases occur, three human cases, the exact cause of infection national and provincial experts are studying.
  
His wife and daughter after the onset of men infected
  
Previously, Zhejiang Province, Wei Planning Bulletin, January 20, 49-year-old Yu Moumou Hangzhou Xiaoshan patient was diagnosed with human cases of avian influenza H7N9 infection. Three days later, the 23-year-old daughter was diagnosed. Both were diagnosed as severe. 27, the hospital again diagnosed, the patient's wife surname Wang Yu Moumou also infected with the H7N9 bird flu, the disease is mild.
  
According to experts in the diagnosis and treatment of avian influenza H7N9, Professor Liang Weifeng, deputy director of the School of Medicine, Division of Infectious Diseases, First Affiliated Hospital, Zhejiang University, introduced in a three-mouth, his father first onset. From 21, had chaperoned daughter began to appear over 俞某某 throat, fever appears from the 22nd, after the hospital virus detection, diagnosis of human infection of H7N9 avian influenza. 22, accompanying her husband's surname Wang had also appeared throat discomfort associated with cough, sputum, etc., and on the 27th was diagnosed human cases of avian influenza H7N9 infection. Currently, Yu Moumou have died due to ineffective treatment.
  
Gathered undetermined etiology
  
The reason for the gathering of disease, some experts believe that there are three common poultry exposure history; while some experts think that the existence of interpersonal secondary transmission between them, the first onset husband passed more likely his wife and daughter. Currently, no clear conclusion of experts.
  
Chinese Academy of Engineering, said Li Lanjuan, even if it is from the family clusters of cases ultimately recognized as limited human to human transmission, we do not have to panic. Issued by the State from the current perspective, sustained human to human transmission has not yet appeared, but simply do not rule out limited non-sustained human-to-human transmission. "The so-called 'limited' refers to the limited scope of infection is the case in nature, rather than the breadth of human to human transmission; while the so-called 'non-sustainable' means that there is no continuous passage of the situation, there is only a mass of individual B, but found no ethylene propylene re-transmission of three generations of cases. "Li Lanjuan academician said.
  
H7N9 prevention and control expert, Zhejiang Chen Zhi Ping, deputy director of the CDC also said that limited human to human transmission is divided into two successor and efficient human to human transmission. Limited human to human transmission is the probability of infection is very low viral interpersonal phenomenon. In this outbreak, some people are predisposed, it is easy to be infected with the virus, but generally does not appear multiple generations of infection, is transmitted up to a person and complete stop after infection.

Avian influenza, limited human to human transmission: the provincial CDC expert Q & A Reporter

January 30, 2014 07:22:21 Hangzhou Network
  
Prevention and control of avian influenza in the province at present the situation is very serious, and have been found to have limited non-sustained human-to-human transmission cases. Experts said that from the current study to see, this particular case showed only a limited non-sustained human-to-human transmission, the virus mutates from the situation, not yet widespread phenomenon of human transmission, the public need not panic too much. However, there are still questions about people's minds: How to understand a limited human to human transmission? As at 12:00 on January 27, the province of human infection with H7N9 avian influenza increased the death toll to 12 people, why the sudden increase in the number of cases of death? Suffering from the flu during the Spring Festival, how doctor? To this end, the reporter interviewed the deputy director of the Center for Disease Control and Prevention Province Chen Zhi Ping, to answer them.

How to understand the limited human to human transmission
  
Reporter: How to correctly understand the limited human to human transmission?
  
Chen Zhi Ping: From the perspective of epidemiological analysis, human to human transmission is divided into two limited human to human transmission of and effective people. Limited human to human transmission is the probability of infection is very low viral interpersonal phenomenon. In this outbreak, some people are predisposed, it is easy to be infected with the virus, but generally does not appear multiple generations of infection, is transmitted up to a person and complete stop after infection, the patient will not be three generations or more on behalf of patients, it does not happen in the school, in the workplace or party. This is the concept of limited human to human transmission.
  
And effective human transmission is different. Such as seasonal flu, influenza, etc. belong to this category. A patient can infect a number of patients, the patients will find even second-generation multi-generational phenomenon patient. Chain of transmission of the virus is also very clear that such phenomena, especially in crowds gathering area, such as schools, communities, units occur.
  
From the current research worldwide, the experts were unable to come up with valid evidence of H7N9 virus from person to person.

Reporter: there is more from our family clustering of cases, how to explain this phenomenon?
  
Chen Zhi Ping: For the family clustering of cases occurred in the province of view, I think it causes more complex cases, including both common exposure, there are factors that limited human to human existence. After careful analysis of these cases found that patients often have blood relations, and are in the process too intimate care on the infection.

Why the sudden increase in deaths
  
Reporter: Zhejiang previously reported one case of deaths, why would the recent report of 11 new cases of deaths?
  
Chen Zhi Ping: This is for a reason. First B infectious H7N9 is legal, according to the Communicable Disease Control Act and people infected with H7N9 prevention and control programs, the situation H7N9 is by the local health administrative departments regularly published on the website of the community each month. Our province is in strict accordance with the national prevention and control programs to outside information published and will be released on April 15th of each month epidemic, the middle will be the time difference. So please be concerned about the circumstances of the province H7N9 epidemic users keep an eye Provincial Health and Family Planning Commission's official website to understand the situation.
  
From January 1 to play Jan. 27, the province a total of 49 cases of human infection with H7N9 avian influenza cases, 12 cases of which died, the mortality of 24.4%. The same time period, the national mortality rate was 28.33%. And this value is compared to slightly lower mortality in our province, but that does not mean that people can relax their vigilance, hope the general public must do individual preventive work.
