Effective Heat Inactivation of SARS-CoV-2



  • Wang et al. evaluate the stability of SARS-CoV-2 under four different heat conditions (37, 42, 56, 60°C) and report that the virus is stable at 37°C for at least 24 hours. However, heating at 56°C for 30 minutes effectively inactivates the virus while preserving the stability of viral RNA for further analysis in both human sera and sputum samples. These findings provide a practical way to inactivate infectious virus in clinical specimens.
