Brief Summary

We have to be aware of the challenge and concerns brought by 2019-nCoV to our healthcare workers. Front-line healthcare workers can become infected in the management of patients with COVID-19; the high viral load in the atmosphere, and infected medical equipment are sources for the spread of SARS-CoV-2. If prevention and control measures are not in place, these healthcare workers are at great risk of infection and become the inadvertent carriers to patients who are in hospital for other diseases. Nowadays a question that has not yet been clarified by science has been arises: is hydroxychloroquine associated with zinc compared to ivermectin associated with zinc effective as a prophylaxis for asymptomatic professionals involved in the treatment of suspected or confirmed case of COVID-19?

Outcome Measures

Primary Outcomes (1)

  • Proportion of participants in whom there was a positivity for SARS-CoV-2.

    Proportion of participants in whom there was a a positivity for SARS-CoV-2 through specific examination (RT-PCR) or by serology for antibodies specific (IgM and IgG), corroborated or not with clinical finding of COVID-19, defined as the occurrence of signs and symptoms suggestive of this disease.

    Post-intervention at day 52

Secondary Outcomes (9)

  • Participants who developed mild, moderate, or severe forms of COVID-19.

    Post-intervention at day 52.

  • Measurement of the QT interval.

    Baseline, 3, 15 and 45 days post-intervention.

  • Widening of the corrected QT interval or with changes in heart rate on the ECG.

    Day 52.

  • Comparison of hematological and biochemical parameters.

    Day 52.

  • Occurrence of adverse events.

    Post-intervention at day 52.

  • +4 more secondary outcomes

Study Arms (2)

Hydroxychloroquine

ACTIVE COMPARATOR

Oral hydroxychloroquine 400 mg twice a day on day 1, one 400 mg tablet on day 2, 3, 4, and 5, followed by one 400 mg tablets every 05 days until day 50th associated with with 20 milligrams twice on day of active zinc for 45 consecutive days

Drug: Hydroxychloroquine

Ivermectin

ACTIVE COMPARATOR

Drug: Ivermectin

Interventions

Oral hydroxychloroquine 400 mg twice a day on day 1, one 400 mg tablet on day 2, 3, 4, and 5, followed by one 400 mg tablets every 05 days until day 50th associated with 66 mg of zinc sulfate.

Hydroxychloroquine

Oral ivermectin dosage guidelines based on participant body weight, once on day for 2 consecutive days. This dose schedule should be repeated every 14 days for 45 days associated with 20 milligrams twice on day of active zinc.
