Questions about Covid

covid.md

1. Why was most of Europe relatively calm for five months and then, faced a second wave all of a sudden?
2. How has Japan been able to minimize the impact of Covid-19 despite doing relatively nothing? Is it masks?
3. How was Pakistan able to peak so quickly (https://prnt.sc/vb1ao0), despite taking few measures to curb the spread? Pakistan demographic is young but is comparable to that of India's.
4. Why is second-wave so far less deadly than the first in Europe? Yes, we are testing more but the difference in mortality rate is huge.
5. On the other hand, the second wave (https://prnt.sc/vb1bzh) in Iran is as deadly as the first. What explains it?
6. Why did India fail so badly at curbing the virus, despite having one of the strictest lockdown? Was compliance at fault?
7. Why, in India, the deaths so heavily skewed towards relatively younger age? <60 age-group deaths contribute 50% to overall deaths (https://twitter.com/MoHFW_INDIA/status/1300969939298263041). This is in stark contrast with somewhere like Italy where <60 deaths form less than 5-6% of overall deaths (https://www.statista.com/statistics/1106372/coronavirus-death-rate-by-age-group-italy/).
8. Masks work, no doubt, but why isn't there a strict correlation between masks use and degree of spread? For eg, Mexico seems to be leading the way in masks compliance (https://prnt.sc/vb7x4g), but their Covid cases + deaths isn't trending down sharply (https://prnt.sc/vb80oe). Japan which has lesser level of compliance, seems to be faring better than most countries. Is the self-reported data here the problem?
