Hydroxychloroquine is an excellent example in risk management. Risk = Severity * Probability. Severity can be as high as death obviously and Probability as we are all learning is the R naught value of infection and as well as the likelihood of how severe are your symptoms going to be to the point of hospitalization and long lasting side effects of the disease (sequelae). Do the benefits of taking this drug outweigh the potential side effects? It’s not like coronavirus is more lethal like ALS or hemorrhagic fever like Ebola. Most people survive with mild to moderate symptoms so hydroxychloroquine is not an appropriate drug to tout to the public at large. An as more drugs are developed with less side effects hydroxychloroquine will go out of favor and the bar for coronavirus drug development will go up. How many drug companies do you hear about are out here competing with Tylenol and Ibuprofen? Not many bc the standards are already so high with minimal side effects.
