Re: The traditional treatment of strep infections has been a [#permalink]

Pls correct if i am wrong and raise question if you have any on the below explanation.
First of all key points in the argument. 1. Many people discontinue the course after 3 days Assumption:- May be they get cured 2. Re Infection chances in those individuals. Assumption:- To avoid re infection take the complete course. In nutshell dont discontinue. 3. New drug is a 3 day course, it provides cure in 3 days. Hence Patients using it will have lesser chance of re infection. Assumption:- Patients will adhere to their 3 days habit and complete the course. Completion of course is important for re infection not to occur.
Now look at answer choice. B and E are contenders thats for sure....B is ruled out as discussed in the preceding post.
E is the best option and also E affirms that Older treatment of 7 day course gives remedy from the disease in 3 days. Thereby strengthening the fact that it is non adherence to the course that it causes the re infection. Hence 3 day course will not cause re infection as people are used to 3 day pattern and it also cures the disease. Hence the people sticking to course of 3 day will prevent the reinfection
---------------------------------------------------------- Consider Kudos if my post helps......
Main issue is: People seem to stop taking the antibotics after 3 days. So a drug has to be effective in 3 days.
A. Some of the people who are allergic to penicillin are likely to be allergic to the new antibiotic. >> Out of scope. Eliminate.
B. A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin. >> Irrelevant. Does not explain why people stop taking antibiotics after 3 days. Eliminate. (Note that if you were using the 2 of 5 rule, this would be one of the 2 remaining options)
C. The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep. >> Out of scope. Eliminate.
D. Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections. >> Irrelevant. Eliminate.
E. Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days. >> Correct choice because it does not weakening nor irrelevant.
