Abstract:

Since the first influenza D virus(IDV) was isolated from swine in 2011, it has been reported that IDVs are widely isolated from swine, cattle and sheep in Mexico, France, Ireland, Italy, China, Japan and northwest Africa. Based on the phylogenetic analysis of whole-genome sequences of these novel influenza viruses, two genetic lineages can be distinguished, D/OK and D/660 lineages. The isolates from China belong to D/OK lineage, and the stains of D/660 lineage are mainly spread in North America. Although IDV can cause mild respiratory disease in susceptible animals, the virus may enter the blood leading to viremia, which poses a serious threat to public health. To raise the awareness about IDV, this review describes the latest researches progress in the study of IDV including its characterization, epidemiology, pathogenicity, diagnosis and prevention.

Key words: influenza D virus, virus characterization, epidemiology, pathogenicity, diagnosis and prevention
