Og vedrørende og SARS-CoV-2 er luftbåren: med denne skal du jobbe hardt for å fortsette å tvile. Du skal i hvert fall argumentere svært godt før du har meg med på laget. Denne kommer på toppen av en serie studier som siden mars alle har pekt i samme retning.
Relevant i ft munnbind-diskusjonen.
Forskere ved University of Florida har nå for første gang påvist store mengder av "levende" virus i aerosol fra pasienter:
«Methods - Air samples were collected in the room of two COVID-19 patients, one of whom had an active respiratory infection with a nasopharyngeal (NP) swab positive for SARS-CoV-2 by RT-qPCR. By using VIVAS air samplers that operate on a gentle water-vapor condensation principle, material was collected from room air and subjected to RT-qPCR and virus culture. The genomes of the SARS-CoV-2 collected from the air and of virus isolated in cell culture from air sampling and from a NP swab from a newly admitted patient in the room were sequenced.
Findings - Viable virus was isolated from air samples collected 2 to 4.8m away from the patients. The genome sequence of the SARS-CoV-2 strain isolated from the material collected by the air samplers was identical to that isolated from the NP swab from the patient with an active infection. Estimates of viable viral concentrations ranged from 6 to 74 TCID50 units/L of air.
Interpretation - Patients with respiratory manifestations of COVID-19 produce aerosols in the absence of aerosol-generating procedures that contain viable SARS-CoV-2, and these aerosols may serve as a source of transmission of the virus.»
De fanget altså virus fra luften inne på pasientenes rom, flere meter unna pasientene som lå i ro. Så klarte de å få viruset til å replikere seg i celler i laboratoriet. Ergo - viruset kan smitte fra luften.
Koronaviruset er luftbåren.
