Seems CV does not care too much about the heat either.

Yes, but heat doesn't tell the whole story. There's no way that climate is going to save anyone single-handedly. If you go shopping and visiting all day, spend lots of time indoors, have generally poor cleanliness and hygiene, fail to wash your hands, aren't careful, etc. it's quite possible to catch a cold or flu -- or COVID-19 -- during the summer.
Climate merely HELPS or HURTS. Colder climates require that you turn on the heat, which lowers the relative humidity, and dries out your throat and nasal passages, making it easier to catch a virus. Plus people stay inside more when it's cold, and consequently get less sun.
COVID virus particles could be dropping like flies, being destroyed by the sun/heat within minutes outdoors all day long -- but when you have hundreds of thousands or even millions of humans interacting with each other indoors on a regular basis -- things are gonna spread.
Note that most of the "Louisiana" cases are in New Orleans. I did some Googling -- the city is 60.2% black, as of 2010. That particular race isn't big on following rules "because it's the right thing to do" or for the love of law & order.
The distant 2nd place for # of COVID cases is Jefferson, which is 23.5% black as of 2000.
Speaking of different peoples reacting to the pandemic differently -- I should point out that in Europe, the average Muslim couldn't care less about the virus. They aren't cancelling a single Muslim ANYTHING. They are proceeding completely business-as-usual.
