Let me make a few of points.
1. First I don't know how old you are, but there could have been changes since you were in the 9th grade. Several Noble prizes have been awarded in that time.
2. They could have found that using Azit. along with other medicines has improved the survival rate by limiting side effects of the anti-viral. Survival is what it is all about, not standing by rules from the past. If Orange juice improved the survival rate, who cares how or why.
3. You talk about people on the CDC. I'm glad there is no 9th grade biology teacher on the CDC. He would be an awful bore and years behind the other members. If I am in ICU and I get a choice between the malaria mix and a ventilator, I would try the pill first. We learn things everyday. Some are saying rolling the patient on their stomach helps.
