SARS-CoV-2 viral dynamics in non-human primates

Non-human primates infected with SARS-CoV-2 exhibit mild clinical signs. Here we used a mathematical model to characterize in detail the viral dynamics in 31 cynomolgus macaques for which nasopharyngeal and tracheal viral load were frequently assessed. We identified that infected cells had a large b...

description Non-human primates infected with SARS-CoV-2 exhibit mild clinical signs. Here we used a mathematical model to characterize in detail the viral dynamics in 31 cynomolgus macaques for which nasopharyngeal and tracheal viral load were frequently assessed. We identified that infected cells had a large burst size (>104 virus) and a within-host reproductive basic number of approximately 6 and 4 in nasopharyngeal and tracheal compartment, respectively. After peak viral load, infected cells were rapidly lost with a half-life of 9 hours, with no significant association between cytokine elevation and clearance, leading to a median time to viral clearance of 10 days, consistent with observations in mild human infections. Given these parameter estimates, we predict that a prophylactic treatment blocking 90% of viral production or viral infection could prevent viral growth. In conclusion, our results provide estimates of SARS-CoV-2 viral kinetic parameters in an experimental model of mild infection and they provide means to assess the efficacy of future antiviral treatments.

primates infected with SARS-CoV-2 exhibit mild clinical signs. Here we used a mathematical model to characterize in detail the viral dynamics in 31 cynomolgus macaques for which nasopharyngeal and tracheal viral load were frequently assessed. We identified that infected cells had a large burst size (&gt;104 virus) and a within-host reproductive basic number of approximately 6 and 4 in nasopharyngeal and tracheal compartment, respectively. After peak viral load, infected cells were rapidly lost with a half-life of 9 hours, with no significant association between cytokine elevation and clearance, leading to a median time to viral clearance of 10 days, consistent with observations in mild human infections. Given these parameter estimates, we predict that a prophylactic treatment blocking 90% of viral production or viral infection could prevent viral growth. In conclusion, our results provide estimates of SARS-CoV-2 viral kinetic parameters in an experimental model of mild infection and they provide means to assess the efficacy of future antiviral treatments.</abstract><cop>United States</cop><pub>Public Library of Science</pub><pmid>33730053</pmid><doi>10.1371/journal.pcbi.1008785</doi><orcidid>https://orcid.org/0000-0001-6239-0110</orcidid><orcidid>https://orcid.org/0000-0002-0943-9648</orcidid><orcidid>https://orcid.org/0000-0001-8932-0171</orcidid><orcidid>https://orcid.org/0000-0002-2322-3392</orcidid><orcidid>https://orcid.org/0000-0002-4734-2249</orcidid><orcidid>https://orcid.org/0000-0002-6261-6412</orcidid><orcidid>https://orcid.org/0000-0002-0918-6804</orcidid><orcidid>https://orcid.org/0000-0001-7895-2720</orcidid><orcidid>https://orcid.org/0000-0002-3826-8729</orcidid><orcidid>https://orcid.org/0000-0002-8759-2429</orcidid><orcidid>https://orcid.org/0000-0002-5534-5482</orcidid><orcidid>https://orcid.org/0000-0003-2862-9751</orcidid><orcidid>https://orcid.org/0000-0002-0555-207X</orcidid><orcidid>https://orcid.org/0000-0003-4784-0819</orcidid><orcidid>https://orcid.org/0000-0001-9393-7684</orcidid><orcidid>https://orcid.org/0000-0002-4928-4484</orcidid><orcidid>https://orcid.org/0000-0002-7045-1275</orcidid><orcidid>https://orcid.org/0000-0002-3210-8468</orcidid><orcidid>https://orcid.org/0000-0002-1520-5020</orcidid><orcidid>https://orcid.org/0000-0001-7609-4742</orcidid><orcidid>https://orcid.org/0000-0003-3070-3017</orcidid><orcidid>https://orcid.org/0000-0002-1148-4456</orcidid><orcidid>https://orcid.org/0000-0001-6682-6313</orcidid><orcidid>https://orcid.org/0000-0002-8959-2123</orcidid><orcidid>https://orcid.org/0000-0002-7559-9527</orcidid><oa>free_for_read</oa></addata></record>
