The National Health and Fam­ily Plan­ning Com­mis­sion, China noti­fied WHO of an addi­tional lab­o­ra­tory con­firmed case of human infec­tion with Avian Influenza A(H7N9) virus. The patient is a six-year-old boy reported from Bei­jing who became ill on 21 May 2013 and is in sta­ble condition.

As of 29 May 2013, WHO has been informed of a total of 132 laboratory-confirmed cases, includ­ing 37 deaths.

Author­i­ties in affected loca­tions con­tinue to main­tain sur­veil­lance, epi­demi­o­log­i­cal inves­ti­ga­tions, close con­tact trac­ing, clin­i­cal man­age­ment, lab­o­ra­tory test­ing and shar­ing of sam­ples as well as pre­ven­tion and con­trol mea­sures. City and provin­cial gov­ern­ments have started to nor­mal­ize their emer­gency oper­a­tions into their rou­tine sur­veil­lance and response activ­i­ties. So far, there is no evi­dence of sus­tained human-to-human trans­mis­sion. Until the source of infec­tion has been iden­ti­fied and con­trolled, it is expected that there will be fur­ther cases of human infec­tion with the virus.

WHO does not advise spe­cial screen­ing at points of entry with regard to this event, nor does it cur­rently rec­om­mend any travel or trade restric­tions. WHO con­tin­ues to work with Mem­ber States and inter­na­tional part­ners to mon­i­tor the sit­u­a­tion. WHO will pro­vide updates as the sit­u­a­tion evolves.
