Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Treatment
Infected patients with acute respiratory tract infection symptoms (e.g. fever, cough, dyspnea) with no other etiology that fully explains the clinical presentation accompanied by chest computed tomography (CT) scan findings compatible with Covid-19 or with a COVID-19 positive test by the polymerase chain reaction (PCR)
Oral 25-Hydroxyvitamin D3
Subjects in the case group will receive 25 mcg of 25(OH)D3 once daily at bedtime for 2 months and the control group will receive placebo daily for 2 months.
Prevention
This arm of study includes the health care providers and hospital workers with a negative test for COVID-19 and a close patient relative with a negative test for COVID-19 who lives with the infected patients.
Oral 25-Hydroxyvitamin D3
Subjects in the case group will receive 25 mcg of 25(OH)D3 once daily at bedtime for 2 months and the control group will receive placebo daily for 2 months.
