About

The primary objective of this study is to evaluate the efficacy and security of chloroquine phosphate prophylactic use for reducing the risk of infection by severe acute respiratory syndrome coronavirus-2 in Health Care Workers exposed to COVID-19 patients.

Full description

Health Care Workers as first line of hospital care, are at high risk of infection by severe acute respiratory syndrome coronavirus-2 due for the exposure to COVID-19 patients. The pharmacological treatment with chloroquine phosphate has emerged as one of the main therapeutic approaches for COVID-19 patients. However, some studies have described and hypothesized that the use of prophylactic chloroquine phosphate could provide some protection against COVID-19 infection reducing the chances of contagion in Health Care personnel during the development of the pandemic. A controlled clinical trial will be conducted in a tertiary hospital in Mexico City, Mexico. Participants will be divide in two groups; 1) intervention: who will receive chloroquine phosphate (300 mg/day during the first 30 days and 150mg/day during the last 30 days) and 2) control, both with a follow up for 60 days.
