Not true. SARS-nCOV-2 possibly has several more tricks up its sleeve and it is not mutating itself out of existence any more than influenza does. We will not know for sure until things return to somewhat normal societal functioning. SERS and MERS seemed to fizzle out after their initial debut. Possibly this coronavirus will be the same. Once the population reaches some level of immunity the virus will possibly only affect the medically compromised - as is the case with most pathogens that the healthy are not affected by. Some patients are requiring more than HCQ depending on how sick they are when they present - but HCQ has shown amazing results in even the very ill. Patients can often deteriorate very quickly after seeking help. Something about COVID allows them to function with very low O2 sats and still appear normal - until they crash. At that point they require different support strategies. The key I believe is early treatment. Granted, we need to do a better job at getting to people early - but we are still figuring this out.
