This image was captured on January 14, 2014, during a H7N9 avian flu investigation, and depicts Chinese Field Epidemiology Training Program (FETP) residents, as they were in the process of collecting environmental samples in a poultry market in Dongguan, Guangdong, China.
The FETP trains workers on the ground to help countries build sustainable capacity for detecting and responding to health threats. The program develops in-country expertise so that disease outbreaks can be detected locally and prevented from spreading.
For more on the FETP, or the avian influenza A (H7N9) virus, see the links below.
On April 1, 2013, the World Health Organization (WHO) first reported 3 human infections with a new influenza A (H7N9) virus in China. Since then, additional cases have been reported. Most reported cases have severe respiratory illness and, in some cases, have died. At this time, no cases of H7N9 outside of China have been reported. The new H7N9 virus has not been detected in people or birds in the United States.
This new H7N9 virus is an avian (bird) influenza (flu) virus. Human infections with avian influenza (AI, or “bird flu”) are rare but have occurred in the past, most commonly after exposure to infected poultry. However, this is the first time that this bird flu subtype (H7N9) has been found in people. This virus is very different from other H7N9 viruses previously found in birds.
