Appraising SARS-CoV-2 virus under the taxonomy category of coronaviridae family, which has been responsible for more than two million fatalities across the globe. It not only jeopardizes the normal life, but also potentiating the evolutionary progress towards a more lethal form. The lethal form, albeit is a bit virulent, is likely to predominate, thereby causing cumulative damage in any cluster that cannot even combat the wide spectrum of genetic variation. The impact on the vertical COVID-19 transmissibility of antenatal population is still sketchy about “nosocomial transmission” and the measures crude. The paper has reviewed the placental pathological findings of pregnant women afflicted with SARS-CoV-2 including the information, gathered from the subsequent stages of gestational outcomes. The possibility of the vertical transmission of SARS-CoV-2 due to the probable placental barrier damage caused by the severe maternal hypoxia, Homo sapiens (human) angiotensin-converting enzyme-2 (hACE2) influenced transplacental migration of SARS-CoV-2 in advanced gestational age, the plausible presence of RNAemia (detection of SARS-CoV-2 in the blood) in hematogenous route was reviewed in this paper. Nevertheless, the probability of susceptible intrauterine or perinatal infection of fetus does not conclusively decide as chances of involving placental coexpression of hACE2 and transmembrane protease, serine 2 in cytoplasmic entry of SARS-CoV-2 remains insignificant, exhibiting the probable relative insensitivity to transplacental infection. The present paper will provide an important insight about the wider understanding of the SARS-CoV-2 pathogenesis in the placenta that canvassed across all trimesters of pregnancy in response to the indiscriminate spread across globe at the time of therapeutic interventions.
