China CDC and CDC investigation at a local market stall, China, 2013

In the early days of the H7N9 outbreak in 2013, China CDC invited CDC to help in its investigation. Vital questions such as the extent of the outbreak, the severity of the disease, and if the virus could change to one that easily spread from person-to-person were still unanswered at the time. To help search fro the answer to these questions, CDC's Dr. Fiona Havers and Dr. Marc-Alain Widdowson provided technical assistance to China CDC. Here, Dr. Widdowson enteres a vendor's stall at a market with Dr. Dale Hsu, Director of the Division of Global Health at U.S. CDC based in China, and Dr. Feng Zijian, Deputy Director of China CDC.
