And with those samples, we were able to use next- generation DNA sequencing methodologies to identify the virus, which, again, turned out to be this very common human virus that had never been seen in chimps before. (cdc.gov)

Since July 1992, a total of 100 clinical and public health laboratories in 47 states have participated in NREVSS and have reported weekly to CDC the number of specimens tested for RSV by the antigen-detection and virus-isolation methods and the number of positive results. (cdc.gov)
However, despite the wide clinical application of andrographolide in viral infection, there are few relevant research focusing on its effects and mechanism on RSV infection so far. (researchsquare.com)
