The arrival of new types of viral diseases, namely coronavirus family, have posed a serious threat for global health. A new kind of coronavirus (CoV) named intense respiratory syndrome CoV-2 (SARS-CoV-2 or COVID-19) firstly diagnosed in Huanan Seafood Wholesale, Wuhan City, China.

This review focused on the persistency of different coronaviruses, like avain H7H9, SARS-CoV, MERS-CoV, Ebola virus and COVID-19, on varied surfaces as well as considering of COVID-19 features such as transmission, preventable policies, symptoms and suggested treatment ways to combat COVID-19.
