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.
