New challenge of asymptomatic infections from COVID-19: current scenario
Keywords:COVID-19, Current scenario, Asymptomatic infections
Since the outbreak of coronavirus 2019 (COVID-19) disease in China, late December 2019, it took a substantial detriment and challenges for more than 200 countries worldwide. Recently with the upcoming insights about etiology of the virus, there is increasing evidence that many patients with COVID-19 are asymptomatic or they have only mild symptoms, but they act as carrier and are able to transmit the virus to others. There are technical difficulties in screening for these asymptomatic infections, which makes it even more challenging for any nation to control this epidemic. This article reviews entry & replication of the virus, pathogenesis, asymptomatic infections, dissemination, prevention, control & treatment in asymptomatic infections with COVID-19, expecting it would be helpful for early prevention and containment of this severe public health threat worldwide.
