In the year of 2013, in China, in human infections, the influenza A virus (H7N9) was diagnosed for the first time, which is a subtype of influenza A virus, of avian origin. Since its discovery, this virus has caused a large number of cases of the disease, thus aiming to gather important information about this virus, such as its occurrence and epidemiology, a descriptive study was developed, from the cases of development of Influenza A H7N9, reported throughout the world, observing the zoonotic characteristics presence. From the analyzes made, it was observed in the period from 2013 to 2015, a total of 571 confirmed cases, with 212 deaths, coming mostly from China, where the infected humans, would have entered into contact with the virus, by exposure to poultries, ou poultries commercialized live in markets. So far there are no descriptions of cases of infection by the Influenza A (H7N9) in humans and poultries in Brazil.
