Discovery of a Novel Human Pegivirus in Blood Associated with Hepatitis C Virus Co-Infection.

abstract：:Environments such as light condition influence the spread of infectious diseases by affecting insect vector behavior. However, whether and how light affects the host defense which further affects insect preference and performance, remains unclear, nor has been demonstrated how pathogens co-adapt light condition to fac...
