Covid-19 has given a halt to all the activities in the world. Europe was most affected followed by the United States of America. Spain and Belgium were found to be at the highest risk of Covid-19 followed by Italy, France, and the United Kingdom. The Covid-19 cases were on the rise in the United States of America and India but with a lower mortality rate. Japan was least affected in comparison to other countries. A normalized method was used to see the mortality of Covid-19 in comparison to other diseases. The deaths occurred by Cardiovascular diseases, cancer, and respiratory diseases were more in number than the Covid-19 caused deaths in the 45 days period where most of the Covid-19 deaths had taken place. The Covid-19 severity was found to be diverse in the world as well as within Europe. This diversity could be a result of the increased number of diagnostic tests or subsidizing other preexisting diseases to count the Covid-19 positive death under Covid-19 or the accuracy of the diagnostic test performed to detect Covid-19. Normalization based on total death counts could be performed to compare the Covid-19 mortality with other diseases to know the real severity of Covid-19.

The commenter has declared there is no conflict of interests.
Comment: Aim of this study is to assess the impact sars cov2 on death rate.. and comparison with pre existing major contributer of death to find the specific impact of sars on mortality.

Limitations can be
Covid infection and death rate data transparency
Ability of the countries to test and treat
Lockdown was not imposed same time over all countries

Economic integration with China

Standardized testing with more specificity and sensitivity

Conclusion may be
We need more data on how many healthy individuals affected and died, and preexisting disease person. To see the real impact sarscov

Overall we very good article sir
