In December of 2019, several cases of atypical pneumonia caused by an unknown agent were reported in Wuhan, the capital city of Hubei Province in China. In early January 2020, it was announced that these cases were caused by a novel coronavirus. The virus was later named Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), which causes a disease associated with atypical pneumonia termed Corona virus disease 2019 (COVID-19). Several respiratory viruses, including coronaviruses and influenza viruses tend to have prominent peaks of infection during colder seasons, especially in temperate regions. The cold temperatures, along with accompanying dry conditions can drive respiratory tract infections by assisting with viral transmission, weakening the human immune system, and increasing viral molecular stability. Though the topic of SARS-CoV-2 transmission and warm weather has been associated with misinformation campaigns, it is worth investigating since an informative answer may give an indication of the future behavior of SARS-CoV-2.
