Abstract
Objective - The objective of this study is to evaluate the association with different factors empirically found to affect the spread and the severity of Covid-19. Evidently there is less likelihood of having one single and absolute solution to this pandemic. It is pragmatic to look for a multi-pronged and collaborative assembly of probable solutions, which is the higher objective of this study. Design - Ecological study. Setting - Global setting including 45 countries from all six inhabited continents Population Two (2) or three (3) countries from each geographical region of the continents selected on the basis of population Main outcome - measures correlation factors derived from comparisons between different sets of variables Results - Empirical trends suggested in the existing literature were quantified in a global setting establishing clear trends. Correlation between the proportion of the population affected and median age, prime climate zones, malaria and tuberculosis incidence, BCG coverage and mitigation measures were established. Conclusions The study findings suggest that demographic and climatological factors, high endemicity of TB and Malaria, and universal BCG programmes may have a cushioning effect in the impact of Covid-19 on health systems of poorer and developing nations. In the light of these findings more emphasis is necessary on the protective effects of BCG and antiviral properties of antimalarial drugs.

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Limitations: We could not obtain excess mortality rates for the time period of the epidemic for many of the selected countries. Attributable risk from BCG vaccination could not be calculated because health data of the infected population could not be sourced in the public domain. We could not obtain complete data of therapeutics being used or of mitigation and alleged suppression tactics used in different countries. All the data was sourced from public domain websites which may have some inaccuracies of their own.
