If the person is feeling poorly, they'll need extra help. I would do nebulizations with hydrogen peroxide, ivermectin 12mg per day for some 3-5 days, lots of vitamin C and NAC, vit D2 and zinc and if available, I would do doxycycline 200mg per day for 7-10 days. It depends on what they have.I know about the table that Gaby posted with dosage according to body weight but I don't know if that dosage is per day or per week.
If it is per day, do they have to take the same dosage every day and for how long.
If there are oxygenation issues, I would give methylene blue 5mg to 10mg twice per day.
