I was sick sometimes ago back when I was in the university. I went to the school clinic and i was treated for malaria but to no avail. Later, I was treated for typhoid which took time to cure.
The treatment for malaria that didn't work strengthened the resistance to that particular drug. If it's been wrongly prescribed over time, the drug will have no effect on the bacteria causing the malaria.
This is why we need personalized medicine to help identify the true illness and the proper prescription.
Thanks for the kind words.
