Topic:

  • Shrestha et al. examined SARS-CoV-2 viral load over time among 230 health care personnel with COVID-19 who did not require hospitalization. Viral loads in the upper respiratory specimens (n=528) peaked by 2 or 3 days from symptom onset and decreased rapidly thereafter, with >85% of the area under the curve occurring in the first five days.
