ELDORET, KENYA — At the Moi University Teaching and Referral Hospital (MTRH), it is not uncommon to see the same patient more than once. But what if it is not sickness causing the patient to return to the waiting room once a week? What if it is because the drugs given do not actually contain medication?In a 2005 survey conducted by National Quality Control Laboratories, 30 percent of all drugs distributed to the public were counterfeit. Counterfeit drugs are a huge problem. But now a device called the Paper Analytical Device (PAD) is being piloted in Kenya by the pharmacists employed at the MTRH.
