A cluster of pneumonia cases of unknown aetiology was reported from Wuhan, Hubei province of China on 31st December, 2019. The World Health Organisation (WHO) declared the outbreak a Public Health Emergency of International Concern (PHEIC) on 30th January, 2020. Thereafter, it has spread through China and reached the level of a pandemic expanding to 210 countries with 77.9M confirmed cases and 1.71M deaths as per Corona virus Disease (COVID-19) situation report issued by WHO based on data received upto 23rd December, 2020. A number of questions remain unanswered regarding pathogen-associated variables for amplification dynamics, host environment and agent interaction. This short communication makes an effort to compile the information gathered from published articles of renowned journals and newsletters to explore the epidemiological characteristics of COVID-19. Hereby in this article, authors have tried to assemble the epidemiological lacunae created by the novel characteristics of the SARS-CoV-2 (Severe Acute Respiratory Syndrome-Corona Virus-2) which presently pose a rather puzzling transmission dynamics of COVID-19 that still remain unanswered.
