The world has been in the midst of a swiftly unfolding public health crisis that has turned deadly. The novel coronavirus disease 2019 (COVID-19), has turned out to be a rapidly expanding pandemic affecting the nations of the world. Most governments and their public health authorities worldwide have taken drastic measures to strictly contain the spread of this coronavirus. However, despite the aggressive preventative measures in place, COVID-19 has propagated exponentially across the world. Currently, the accepted mode of disease transmission is by droplets containing the virus. Here we provide epidemiological data in conjunction with biochemical molecular mechanisms of this Severe Acute Respiratory Syndrome- Coronavirus-2 (SARS-CoV-2) and explain the possible alternative modes of disease transmission. Our observed data, biochemical mechanisms, and inferences indicate that COVID-19 has a high probability of transmission through other routes as well, such as indirect routes; viz, fomites and aeros.
