How text messages help to fight Malaria in Nigeria and Ghana
Mobile phones could soon be helping re-assure Nigerians and Ghanaians they are getting genuine medicine.
A pilot scheme in the two nations has begun putting unique scratch codes on more than 500,000 medicine bottles and packets of pills.
When the code is texted to a free phone number, a return message will reveal that a drug is genuine.
The scheme hopes to boost efforts to tackle diseases such as malaria and combat the rise in fake medicines.
