Abstract. Summary - We have drawn a graph of the time evolution of  lethality rate of Covid-19 in the World.

Note that Covid-19's fatality rate has increased since the start of the pandemic. One explanation for this growth is deaths from comorbidity due to the lack of beds in hospitals. Another logical explanation would be the evolution of the virus itself. A third explanation would be the over-attribution of deaths due to Covid-19, as many countries have not tested for the entire population. 

Observation: note that in our graphs we take time in descending order.
