Due to the rapid spread and infection of a large population, it is difficult to maintain the complete databases of every individual. Hence, there is a lack of information in the demographic data. Existing demographic data analysis shows that there are variations in the age distribution of COVID-19 infected cases in South Asian countries. Most of the patients, infected with SARS-CoV-2 are young adults aged between 21-30 years except for Pakistan where people aged between 31-40 years are the most vulnerable and in Sri Lanka where the majority of the patients are aged between 41-50 years (Figure 1) [23–29].
