The main route of transmission of SARS CoV infection is presumed to be respiratory droplets. However the virus is also detectable in other body fluids and excreta. The stability of the virus at different temperatures and relative humidity on smooth surfaces were studied. The dried virus on smooth surfaces retained its viability for over 5 days at temperatures of 22–25°C and relative humidity of 40–50%, that is, typical air-conditioned environments. However, virus viability was rapidly lost (>3 log10) at higher temperatures and higher relative humidity (e.g., 38°C, and relative humidity of >95%). The better stability of SARS coronavirus at low temperature and low humidity environment may facilitate its transmission in community in subtropical area (such as Hong Kong) during the spring and in air-conditioned environments. It may also explain why some Asian countries in tropical area (such as Malaysia, Indonesia or Thailand) with high temperature and high relative humidity environment did not have major community outbreaks of SARS.

- Airborne transmission of respiratory viruses (2021, background): “SARS-CoV (132), SARS-CoV-2 (133), and influenza virus (134) are more stable at lower temperatures, possibly because of slower decay rates (as governed by the Arrhenius equation) and stronger ordering of phospholipids for enveloped viruses.”
- A Mouse Model of SARS-CoV-2 Infection and Pathogenesis (2020, positive): “Third, experience from SARS and MERS supported that human CoVs maintained their viability in environmental conditions essential for fecal-oral transmission (Chan et al., 2011; van Doremalen et al., 2013).”

- Effects of temperature and humidity on the daily new cases and new deaths of COVID-19 in 166 countries (2020, positive): “Firstly, studies have reported that SARS-CoV-2 is sensitive to high temperature and humidity (Chin et al., 2020; van Doremalen et al., 2020; Chan et al., 2011; Sun et al., 2020; Ma et al., 2020; Wu et al., 2020; Xie and Zhu, 2020; Yao et al., 2020).”
- Association between ambient temperature and COVID-19 infection in 122 cities from China (2020, background): “Another laboratory study found that coronavirus on smooth surfaces was stable for over 5 days when temperature at 22°C-25°C, and virus viability was rapidly lost at higher temperatures (e.g., 38°C) (Chan et al., 2011 ).”
