This is what's known as
anecdotal evidence. People who don't work in science may not understand that "anecdotal evidence" is an insult to a scientist. It isn't good enough evidence to be convincing. That one sick person's comments are:
- casual observations or indications rather than rigorous or scientific analysis
- information passed along by word-of-mouth but not documented scientifically
- evidence that comes from an individual experience. This may be the experience of a person with an illness or the experience of a practitioner based on one or more patients outside a formal research study.
- the report of an experience by one or more persons that is not objectively documented or an experience or outcome that occurred outside of a controlled environment
There is strong, convincing, scientific evidence that hydroxychloroquine provides no benefit for critically ill Covid-19 patients. In a risk vs. benefit analysis, hydroxychloroquine fails. The media did report that.
