Reports about the potential of hydroxychloroquine as a potential treatment for Covid-19 have been circulating among New York City emergency physicians for more than a week, and some patients are reportedly getting the hydroxychloroquine/azithromycin combination. (Perhaps as a result, there are shortages cropping up for patients with lupus and other diseases who need the drug.) The University of California, San Francisco, and the University of Washington both recommend hydroxycholoroquine for very sick Covid-19 patients.
