India basically doesn’t have it. Neither does Indonesia.
Cases there are imported (ie, travelers from Italy or Iran).
Viruses don’t do well in high heat and high humidity. Nobody knows why, and some kind of studies should be done (is it heat, humidity, vitamin D, or ultraviolet light?)
In the next decade there will be libraries filled with papers. Why Brazil and not India may be a wing of the library. Waiting for Spring is not an option for us. Spring is here in days IIRC. Let’s all hope that the # of death today is heading south severally in two weeks. It would mean we don’t need to do anything else. It would be great if it was so sensitive to light and moisture we could drop all this in two weeks. Much better than putting hundreds of thousands of people on HCQ.
