Indeed we do not know of an effective treatment for COVID-19 today. All evidence is anecdotal only. Some people who don’t understand what they are talking about are promoting a flawed French study of hydroxychloroquine. But a much better Chinese study found that it didn’t help. Nevertheless the Chinese study was small so clinical trials are underway. Similarly, there are clinical trials of other possible treatments and also of a possible vaccine.
You can find the clinical trials at clinicaltrials dot gov. Pray for their success and STAY HOME.
