According to the authors, COVID-19 poses two major challenges to physicians: therapeutic management of patients, and the rapid spread of the disease in the population through contagious individuals. The researchers have provided evidence of  a beneficial effect of co-administration of hydroxychloroquine with azithromycin in the treatment of COVID-19 and its potential effectiveness in the early reduction of contagiousness.

Clinical and microbiological effect of a combination of Hydroxychloroquine and Azithromycin in 80 COVID-19 patients with at least a six-day follow up: A pilot observational study

 This is a descriptive pilot study conducted in only 80 patients with relatively mild clinical presentation and the researchers did not attempt an analytic approach to account for possible confounding factors including notably the severity of illness. Such an approach is currently planned in a larger set of patients under treatment at the institute in which this study took place.
