Group 1 Ozone (experimental). Rectal ozone therapy + Cuban national action protocol for Covid-19. Version 1.6.. Ozone therapy: It will be applied by rectal insufflation according to the following scheme Day 1: 100 mL of gas with 30 μg / mL of Ozone concentration, (3 mg of ozone) every 12 hours Day 2: 150 mL of gas with 35 μg / mL of Ozone concentration, (5.25 mg of ozone) every 12 hours Day 3-10: 200 mL of gas with 40 μg / mL of Ozone concentration, (8 mg of ozone) every 12 hours. The treatment will finish with 20 sessions of rectal ozone therapy for 10 days. Cuban national action protocol for Covid-19. Version 1.6: Heberferόn ® Interferon α-2b recombinant + Interferon gamma recombinant, according to the national form 3, 5 M IU, by intramuscular route, every three days, it is administered one day, two days are waited and it is applied again. Kaletra: 2 tablets every 12 hours, for 10 days. Chloroquine 1 tablet every 12 hours, for 10 days. Broad spectrum antibiotics if you suspect bacterial over-infection (Ceftriaxone 1gr to 2gr every 12 hours: in patients where associated bacterial infection is diagnosed. The decision to use another antibiotic will be determined by the results of laboratory studies and the microbiological map of the service).
