As of 14 April 2013 (18:00 CET), the National Health and Family  Planning Commission notified WHO of an additional two  laboratory-confirmed cases of human infection with influenza A(H7N9)  virus from Henan. 
 
 The first patient is a 34-year-old man who became ill on 6 April  2013, and the second patient is a 65-year-old man who became ill on 8  April 2013. 
 
 To date, a total of 51 patients have been laboratory-confirmed  with influenza A(H7N9) virus in China; including 11 deaths. More than a  thousand close contacts of the confirmed cases are being closely  monitored. 
 
 Investigations into the possible sources of infection and  reservoirs of the virus are ongoing. Until the source of infection has  been identified, it is expected that there will be further cases of  human infection with the virus in China. So far, there is no evidence of  ongoing human-to-human transmission. 
 
 WHO does not advise special screening at points of entry with  regard to this event, nor does it recommend that any travel or trade  restrictions be applied. 
 
 About this Disease Outbreak News 
 
 1. WHO is currently publishing information on  laboratory-confirmed cases received through the official notification  from the Chinese National International Health Regulations (IHR) Focal  Point once a day. This formal notification and publication follows  verification of the information, and may therefore come after, or not  include, some cases reported through public media and other sources. 
 
 2. To date, there is limited information to determine whether  the reported number of cases represents some or all of the cases  actually occurring. As some relatively mild cases of illness have now  been reported, it is possible that there are other such cases that have  not been identified and reported. 
 
 3. If the current pattern of sporadic infections continues, WHO  will cease frequent reporting of case numbers, and focus its Disease  Outbreak News on new developments or changes in the pattern or  presentation of infections.
