Influenza D virus was not detected among prospectively studied swine farm in multiple provinces of China.

This article discusses the absence of Influenza D virus (IDV) in a study conducted on swine farms in multiple provinces of China. IDV is a type of influenza virus that was first discovered in pigs in the United States in 2011 and has since been detected in various animal species. The study collected samples from swine farms in Jiangsu and Shandong Provinces over a five-year period and tested them for IDV using quantitative real-time polymerase chain reaction (qRT-PCR). The results showed no detection of IDV in the samples, which is consistent with a previous study in Vietnamese swine farms. The authors suggest that periodic surveillance for IDV should continue to better understand the virus's ecology and potential impact on agriculture and human health. [Extracted from the article]
