Transmission of SARS-CoV-2: A iReview

Abstract

The World Health Organization recognized SARS-CoV-2 as a public health concern and declared it as a pandemic on March 11, 2020. Over 12 million people have been affected across several countries since it was first recognized. SARS-CoV-2 is thought to commonly spread through respiratory droplets formed while talking, coughing, and sneezing of an nfected patient. Broadly, two modes of transmission of COVID-19 exist direct iand indirect. The direct mode includes transmission via aerosols formed through surgical and dental procedures and/or in the form of respiratory droplet nuclei; other body fluids and secretions such as feces, saliva, urine, semen, and tears; mother-to-child. Indirect transmission may occur through fomites or surfaces present within the immediate environment of an infected patient and objects used by the infected person. As many of these modes may be underestimated, it is necessary to emphasize and llustrate them. Understanding how, when and in which settings infected people transmit the virus is mportant for developing and implementing control measures to break chains of transmission.The aim of this paper is to briefly review how SARS-CoV-2 transmit via various modes and propose measures to reduce the risk of ispread within the population.
