Erratum to: Emerging Microbes and Infections (2013) 2, e18; doi:10.1038/emi.2013.18; published online 10 April 2013
Due to the production error, a typo has been introduced on the third, fourth, and fifth sentences in the last paragraph of this News and Views. “H9N7” should be “H7N9” in these sentences. The correct information is as follows:
Among them, one is a four-year-old child with very mild respiratory infection symptoms but showed H7N9 positive by polymerase chain reaction in his throat swab. Currently in Shanghai and several other provinces, strict survey for H7N9 cases has been implemented in outpatients with fever and respiratory infections in all hospitals. At the same time survey for H7N9 among wild birds and poultries has been carried out by the animal Centers for Disease Control and Prevention, and confirmed by the National Key Laboratory of Avian Influenza Institute in Harbin.
