Nicely done anlysis linking patterns of infection in Italy vs Peru/Brazil to general differences observed by a researcher many yrs ago.

Does Lockdown give a great bang for the buck? Or is #coronavirus seasonal by nature, with its own dynamics?

Temperate northern hemisphere regions show the familiar bimodal pattern (high in early and late periods of year but low in middle months) while tropical southern hemisphere regions have more of a bell shaped pattern with a peak period lower than the northern hemisphere peak.

Superimposing those distribution patterns over the death/million curves of Italy and Peru/Brazil show a pretty compelling match.

Also note, as presenter does, similarity between Peru and Brazil. Peru did hard lockdown back in March. Brazil didn't. No significant difference in the mortality curves.
