Again looking at infection data, hot countries have low numbers

One example is Singapore which has decent modern medicine. All the hot countries are low. Singapore is in the 90's during the day. Point is as the northern hemisphere warms, should see new cases dropping off.

New study says 'high temperature and high relative humidity significantly reduce' spread of COVID-19

Here you go!
A team of researchers unveiled the results of a new study last week that looked at how temperature and humidity may affect the transmission of COVID-19, the illness caused by the new coronavirus.

According to the researchers' findings, "High temperature and high relative humidity significantly reduce the transmission of COVID-19." An increase of just one degree Celsius and 1% relative humidity increase substantially lower the virus's transmission, according to the data analyzed by the researchers.

The study is the latest in a limited but growing body of research, not all of which has been peer-reviewed, that examines the effect of weather on the spread of the SARS-Cov-2 virus, which causes the COVID-19 illness.

That may be. On the other hand, Singapore is an island and has social conformity standards that make quarantine much more enforceable — no "social distancing." Leave your house and you will be fined or jailed or both.

This would be good news. It will be interesting to see how it plays out in Subsaharan Africa, which is bracing for really bad news. In much of Africa, statistics will mean next to nothing because of undeveloped public health reporting. Kind of like the U.S. without adequate testing.

It may not result in too many deaths there as there are not as many old people there. CDC says in the USA, 8 in 10 deaths are people older than 80 yrs old. Many poor countries dont have as many old citizens. 80% of people have either no or mild symptoms. What could happen who knows, as African's individual medical conditions are probably not as good when they are younger versus younger citizens in wealthier countries. Another fact is people in wealthy nations live a lot longer but they are also a lot sicker than younger folk, it does not take much for them to die. Many are one foot out of the grave before getting covid - 19.

Age is best explainer of coronavirus infection differences between countries but there is another surprising factor

More evidence hot countries are doing remarkably better. Now it is noted not only only the high humidity and temperatures, but also the BCG vaccine.

Age, BCG vaccine, climate are factors that limit the spread.

Countries that either never had BCG vaccination programs (Italy, Netherlands, Belgium, USA) or discontinued it some time ago (Spain, Sweden, U.K., Switzerland, France) are faring worse, he says.

That’s one area where emerging markets have western nations beat, as most all of them do have mandatory BCG vaccination. One that doesn’t is Ecuador, with the highest emerging-market COVID-19 mortality.

Finally, emerging markets tend to be in hotter and humid areas, Kolaonvic notes. A number of research papers that indicate that higher temperature and humidity may reduce COVID-19 infection rates, he says.
