A quasi-geographic view of the coronavirus pandemia

When one analyzes the geographical distribution and the season of the year in which the coronavirus developed, one notices that the most affected countries were in the winter season. 

Most of them (I would say, all of them) are in the northern hemisphere in some of the coldest months (february through march).

China, Korea, Italy, Spain were (are) coming out of winter. In Italy the focus is on the north (colder) eg Lombardia and principally Milán. There are less cases in the south (Sicily, Campania). In the US most cases occur in some of the "colder" states (New York, Seattle in the state of Washington).

It is by no means the only cause, but it seems quite clear, "winter" creates environments to facilitate the development of the virus and contagion. In winter respiratory diseases abound, the air in closed environments is less renewed.

Also, people in "winter" countries (for economic reasons because they are generally wealthier countries) people travel more (internationally).

Some data shows that this virus moves more in environments of "travelers", which are often people with more financial resources. For these reasons we notice that many highly influential political or aristocratic figures (J. Trudeau’s wife, Prince Charles, J., Tom Hanks and wife, Pedro Bordaberri (in Uruguay) etc.) have tested positive.

In Sub-Saharan Africa there are far fewer cases. Sanitary conditions are much worse, the health systems are not very good, but however the virus did not expand much.

Same with India, with a population of 1.3 billion people, Indonesia, Vietnam, etc.

There are some cases in these “tropical countries” but far less.

In many Latin-American countries, which are also located in tropical latitudes (or in the south, coming out of the summer season), the virus mainly spread among travellers, their families and their closest social environments. It is the case in Argentina and Uruguay (in this last country the upper-class neighbourhood Carrasco dominates the statistics).

Another thing is lethality. 

There you have to take into account the efficiency and coverage of health systems (obviously the Canadian health system is better prepared and has wider coverage than the US) and the German system is more efficient than the Italian or Spanish systems.

We will see if and how the new data confirm or not this very preliminary quasi-geographic analysis.
