Viral Emissions into the Air and Environment after SARS-CoV-2 Human Challenge: A Phase 1, Open Label, First-in-Human Study
Effectively implementing strategies to curb transmission of SARS-CoV-2 (the virus that causes COVID-19) requires understanding who is contagious and when.
Whilst viral load (VL) on upper respiratory swabs has commonly been used to infer contagiousness, measuring viral emissions may be more accurate to indicate the chance of onward transmission and identify likely routes.
This paper, from theme 5 researchers on the PROTECT NCS, discusses the findings from the first human challenge study with SARS-CoV-2.
