As a new disease, it is lack for the knowledge on the new H7N9 influenza. Here, the author will discuss on the impact of emerging H7N9 influenza on pregnancy. New emerging disease is a concern in public health. The cross species atypical H7N9 influenza virus infection originating in China is a big global problem at present [1 -2] . As a new atypical influenza, the great fear is on the worldwide epidemic as previously seen in the previous outbreak on atypical influenza infections, H5N1 bird fu [3] and H1N1 swine flu [4] . O f i n t e r e s t , a l t h o u g h H 7 N 9 i n f l u e n z a c a u s e s respiratory illness, additional atypical manifestations can also be seen [5 -7] . Since its first emerging in China, upto 130 cases has been accumulated (30 May 2013). This short article specifically focuses on the new emerging H7N9 influenza which has just been observed since early 2013. As a new disease, it is lack for the knowledge on the new H7N9 influenza. Here, the author will discuss on the impact of emerging H7N9 influenza on pregnancy. The new H7N9 influenza can infect anyone, in any age group and sex [5 -6] . As a disease resulted from genetic alteration [8 -9] , the pathobiological process due to the infection might be different from classical influenza can be expected. It is useful to gathering the data of this specific new infection. In obstetrics, the data of this new infection is highly required. Focusing on the pregnant, only a few reports are available for H7N9 influenza. Nevertheless, it is no doubt that pregnant patients are at risk for get severe influenza [10] . For the new emerging bird flu, the severe illness can be seen. The good example is the previous situation in outbreak of H1N1 swine flu [11] and H5N1 bird flu [12] . For the present This short article specifically focuses on the new emerging H7N9 influenza which has just been observed since early 2013. As a new disease, it is lack for the knowledge on the new H7N9 influenza. Here, the author will discuss on the impact of emerging H7N9 influenza on pregnancy. The prevention of influenza is an important in preventive obstetrics. Generally, influenza vaccination is recommended for the pregnant [13] . However, as a new infection, no vaccine for H7N9 influenza is available at present. Although the pregnant is classified as a risk group, the antiviral prophylaxis is not recommended. Influenza as a model system for studying the crossspecies transfer and evolution of the SARS coronavirus How to define the species barrier to pathogen transmission? Avian influenza: a new pandemic threat? Swine influenza viruses a North American perspective Emergence of Avian Influenza A(H7N9) Virus Causing Severe Human Illness -China An overview of the recent outbreaks of the avian-origin influenza A (H7N9) virus in the human Genetic analysis of novel avian A(H7N9) influenza viruses isolated from patients in China Pathogenesis and transmissibility of highly (H7N1) and low (H7N9) pathogenic avian influenza virus infection in red-legged partridge (Alectoris rufa) Avian influenza in North America Management of influenza in pregnancy Obstetrical concern on new emerging swine flu No evidence of gynecological and obstetrical manifestation in H5N1 influenza virus infection Vaccination against influenza in pregnant women -safety and effectiveness We declare that we have no conflict of interest
