Abstract:

Human Corona viruses are coronaviridae virus belongs to enveloped single stranded RNA virus. It is a group of viruses that cross species barrier and transmitted from their animal reservoirs to become responsible for human infection with wide genetic diversity. Many of Corona viruses have been responsible for infection in human, which is usually mild in healthy adult, and do not have any concern with treatment or vaccination, like other endemic viruses as infleunza virus, respiratory syncytial virus and rhinoviruses. Until outbreaks of infection with acute respiratory distress syndrome, caused by highly pathogenic strains with severe acute respiratory syndrome coronavirus (SARS CoV). The last outbreaks was at 2019 with the novel SARS-CoV-2 infection, when 91000 people infected and 3120 people dies and by 3^rd of march 2020 and it was the start of world pandemic in Wuhan (china), with medical and scientific challenges for china and the world started with many social limitation. The SARS-CoV-2 responsible for the pandemic has 96% similarity to the bat SARS like corona virus and to cause human infection the virus has several adaptation and minor changes in its sequence to improve its fitness to infect the cells of the new host. SARS-Co-2 has high spread rate in human and for each human infected patient there will be 2-3 individuals are infected and the virus remains infectious as aerosols up to three hours and few days on the surrounding surfaces. This review highlighted the impact of coronavirus on fertility.
