# 9508


H7N9 reports out of Zhejiang Province, China continue to emerge piecemeal, with no single authority making announcements. The Zhejiang Health and Family Planning website, a place we’d normally look for such reports, remains strangely quiet on H7N9.


Over the past couple of days we’ve seen two H7N9 cases reported out of Zhejiang – a 57 year-old man from Jinhua on the 27th, and yesterday a 75-year-old man Zhoushan townThese cases are geographically quite distant from one another and are not linked.


Today we are seeing reports of a 20 year-old from Shaoxing  City and a 33 year-old from Yongkang City having been diagnosed with the virus.  


Our first stop, the Shaoxing City Municipal Health Bureau (h/t Shiloh on FluTrackers for the link).

According to CDC epidemiological investigation, the patient Xing Moumou, female, 20 years old, currently living area keqiao Anchang, one week prior to the onset has been to the farmers market, no clear history of exposure to poultry, currently in critical condition, still active treatment, the epidemic prevention and control measures are being ordered implemented.

BEIJING, Dec. 29 Jinhua (Reporter Hu Fengsheng) 29 evening, according to the government press center Yongkang official microblogging "Yongkang release" message in the afternoon, Yongkang confirmed three cases of H7N9 flu cases first. It is in this winter, following Jiaxing, Zhejiang Yiwu confirmed two cases since the emergence of the first five cases. Zhejiang Province, according to the CDC epidemiological investigation, before the onset of the previous two patients had history of exposure to poultry. The former situation is different in the two cases is that the patient is female, Lee, 33, East Street who is now being treated in isolation.

Preliminary statistics, there are close contacts with Lee 4, currently in good health, fever, cough and other symptoms did not appear suspicious, other close contacts is under investigation.

According to information released by the relevant departments, two cases found in previous cases, one case has died and another is in critical rescue in one case.

Local representation, analysis of these three cases, no timely attention to flu symptoms is a key factor in exacerbations, and epidemiological point of view, H7N9 influenza in Yongkang still sporadic cases, there is no direct correlation. According to the law in previous years, winter and spring are people infected with H7N9 influenza virus in a high incidence of, based on this law, the health department said the next period of time, do not rule out the case there will be sporadic cases. Local government appeal: people cough, fever and other symptoms, be sure to go to hospital for treatment.

Health department Again, try not to touch live poultry, once exposed, must be cleaned and disinfected. Also, to develop good habits and a healthy lifestyle, a balanced diet, regular exercise, pay attention to rest, to improve their resistance to disease; wash their hands frequently ventilation, timely change clothes, to avoid the cold.


Admittedly, we try to document as many confirmed cases of novel influenza as possible. But it is with the knowledge that we are probably only seeing the tip of the iceberg.  For every hospitalized case, we suspect there may be a number of mild or asymptomatic infections that go undetected.


We’ve seen estimates (see Eurosurveillance Clinical severity of human infections with avian influenza A(H7N9) virus, China, 2013/14) that there may have been thousands of undetected H7N9 cases in China over the past two years, although no one really knows for sure.


While a few family clusters have been reported, reassuringly among close contacts of known H7N9 cases, very little transmission appears to have taken place.  For now, bird-to-human transmission appears to be the norm.


Although it may not be possible for surveillance and reporting systems to capture the full impact of these outbreaks, the ability to closely examine a subset of cases can still provide excellent insights into the behavior of, and risks posed by, this emerging virus.
