A preprint of a Brazilian study using HCQ and azithromycin shows promising results
Of the 636 symptomatic outpatients, 412 started treatment with hydroxychloroquine and azithromycin and 224 refused medications (control group).
Need for hospitalization was 1.9% in the treatment group and 5.4% in the control group (2.8 times greater) and number needed to treat was 28 (NNT = 28). In those who started treatment before versus after the seventh day of symptoms, the need for hospitalization was 1.17% and 3.2%
Conclusion
Empirical treatment with hydroxychloroquine associated with azithromycin for suspected cases of COVID 19 infection reduces the need for hospitalization
