#COVID19-positive Teilnehmer der Studie atmeten in den ersten 8 Tagen nach der Infektion durchschnittlich 80 #SARSCoV2-Virus-RNA-Kopien pro Minute aus, darunter Spitzenwerte von über 800 Kopien pro Minute bei einigen Patienten. Nach dem 8. Tag kam es zu einem steilen Abfall auf
Fig 2. (A) Levels of exhaled SARS-CoV-2 RNA copies per minute over the course of infection. Each dot represents the daily average number of exhaled SARS-CoV-2 RNA copies exhaled per minute, for each participant. The overlaid black line represents the rolling average of exhaled viral RNA copies over days since symptom onset. The overlaid red line is the fitted S curve (R'= 0.7657, adjusted R'= 0.7567, RMSE: 0.3755). The green vertical dashed line indicates the inflection point of the S curve. (B) Viral RNA copy numbers binned over days since symptom onset. Each dot represents results from one sample. Mean and standard error are represented by red lines within each bin. * indicates P < 0.05. (C) The same data from panel A are plotted, with colored dots representing samples that were collected from vaccinated participants, and grey dots representing unvaccinated participants. (D) The same data from panel A are plotted with blue indicating participants infected with Omicron strains; red …

COVID-Patienten atmen in den ersten acht Tagen nach Auftreten der Symptome hohe Virusmengen aus, bis zu 1.000 Virus-RNA-Kopien pro Minute.

Diese Studie liefert wichtige Daten zur Dynamik der #SARSCoV2 -Ausscheidung in der Ausatemluft im Verlauf der Infektion. 🧵

COVID patients exhale as many as 1,000 copies of the virus per minute during the first eight days of infection. Virus copies peak from Day 0 to Day 7. By day nine, exhaled levels of virus drop steeply, down to an average of two copies per minute.
