Chickens at a vendor's stand in live market
The large populations and close quarters of chickens and ducks in Chinese markets are a breeding ground for influenza viruses. Viruses are common in the dense markets but are rarely transmitted to humans; however there is always a possibility for infection. In April, a new flu virus (H7N9) was contracted and since passed to 130 human handlers and killed at least 40 people.
The virus forms when passed from bird to bird, changing as necessary to survive and residing in the respiratory tract. Working closely though handling, humans contracted the virus. Medical professionals in China as well as commercial vendors suggest keeping clucks and quacks separate in the markets to prevent the development of viruses dangerous to human health.
