The relation between the virus and the population condensation.
The reason I realized this may has big effect is because of the news in the past few days. It draw some relation between the infection among minorities in the US and being infected .
The African Americans and the Latino populations tend to live in urban condensed neighbourhood wile white American tend to live in the suburbs where it is less condensed .that is plus the opportunity of having health insurance the differ among race as well.
I think it might be a trend that could be studied here but not sure how to start a study like this.
I thought this might be interesting to investigate.
Also when talking about it to one of my teachers he add up a new factor that might support this theory ,he said "In Italy, Spain and south Europe usually grand children have lots of interactions with their grand parents, that maybe a reason for the spike numbers in the southern part of Europe other than the northern part when it is usually happens in a much lesser degree".
