Stability of SARS Corona Virus in Humans and Environment

Abstract

Severe acute respiratory syndrome (SARS) is a single stranded RNA virus, it infects the epithelial cells within the lungs. . Moreover, these infections can be successfully inactivated by lipid solvents including ether (75%), ethanol, chlorine-containing disinfectant, peroxyacetic corrosive and chloroform with the exception of chlorhexidine. The viability of a few povidone-iodine (PVP-I) items, various other synthetic operators, and different states of being were assessed for their capacity to inactivate the extreme intense respiratory condition coronavirus (SARS-CoV). The stability of SARS coronavirus in human specimens and in environments was studied. The survival abilities on the surfaces of eight different materials and in water were quite comparable, revealing reduction of infectivity after 72 to 96 h exposure. Viruses stayed stable at 4°C.The survival of the virus seems to be relatively strong in humans and environment. Heating and UV irradiation can eliminate the viral infectivity.SARS,to be transmitted through respiratory droplets, fomites or tainted sewage frameworks. Presence of  different strains of coronavirus has led to complications in the field of vaccine and medicine.Hence, this study sheds light on the stability of the different strains of virus (SARS CoV) in humans and environment. And also this study emphasizes on the physical and chemical methods of inactivation of SARS CoV. Thus, The necessity and aim of this study is to understand the knowledge about stability of SARS CoV in order to predict the future antiviral treatment and coping methodologies.
