I actually read the study. Nothing in the study indicated HCQ was used with zinc or zpak. http://www.zjujournals.com/med/CN/10.3785/j.issn.1008-9292.2020.03.03
This could tell us a lot though. Just like with the flu, the following bacterial infections could be more distressing to the person than the virus. I'd be interested to see the results of a trial that had control groups with only HCQ, with HCQ and zithromax, and with HCQ and levaquin.
