Environmental Concern Regarding the Effect of Humidity and Temperature on SARS-COV-2 (COVID-19) Survival: Fact or Fiction

The new coronavirus, called nCoV-2019 (COVID-19), is a new type of virus that was first identified in Wuhan, China, in December 2019. COVID-19 is from the same family as the severe acute respiratory syndrome (SARS), community-acquired pneumonia (CAP), and other common colds. The environmental conditions necessary for the survival and spread of COVID-19 are somewhat clear, but unlike animal coronaviruses. We are poorly aware of their survival in the environment and the precise factors of their transmission. However, limited studies in this field show that COVID-19 are more resistant to environmental factors than other coated viruses. Though the effect of humidity and temperature on COVID-19 activity is controversial, published evidences report that it significantly contaminates air, surface environment, and protective equipment by droplets of infected person, meaning that environment is important issue to consider, because roles as a potential medium of transmission; thus, it is necessary to strict adherence to environmental and personal protection and hygiene, as well as social distancing.
