Therefore, it is essential to understand the survival of SARS-CoV-2 in the ambient environment to prevent COVID-19. This information is very useful not only for the policymakers but also for the general population. Many previous investigations have shown that the viability of viruses is strongly dependent on temperature (Tang, 2009; Huang et al., 2018). Transmission of influenza can be reduced under high temperature conditions (Lowen et al., 2008). It has been proven that high temperatures can effectively deactivate viruses, resulting in a large reduction in the amount of active viruses (Park et al., 2020). Recent studies have shown that the rate of confirmed COVID-19 cases is closely related to temperature (Triplett, 2020; Luo et al., 2020; Xie and Zhu, 2020). It is of great importance to determine the preferred temperature range of SARS-CoV-2 in order to help us prevent the COVID-19 outbreak. Particularly, hospitals and densely populated areas can be informed about optimal temperature ranges to reduce the probability of cross-infection. However, such knowledge is not currently available for SARS-CoV-2, which is a novel virus. Therefore, it cannot be utilized yet to prevent the spread of the COVID-19 pandemic.
