Brief summary

This is a randomized, open-label trial to assess the safety and efficacy of hydroxychloroquine, and zinc in combination with either azithromycin or doxycycline in a higher risk COVID-19 positive outpatient population.

Detailed description

COVID-19 is an aggressive and contagious virus, found to have high mortality especially in persons with comorbidities (Age\>60, hypertension \[HTN\], diabetes mellitus \[DM\], Cancer, and otherwise immunocompromised). Zinc is a supplement with possible antiviral properties, having been shown to have effect in the common cold, many of which are due to coronavirus. In addition, elderly patients and patients with co-morbidities have high incidence of zinc deficiency. We are repleting zinc in all patients and studying its direct effect in combination with hydroxychloroquine, and an antibiotic, either azithromycin or doxycycline to see if there is enhanced treatment efficacy in early COVID-19 infection and assess the safety of these two regimen.
