Few better illustrations of natural selection exist than the repeated emergence of resistance to such drugs. Even artemisinin, the most recent addition to the arsenal, has already provoked an evolutionary pushback.

At the moment, working out which drugs, if any, a particular case of malaria is resistant to means sending a sample to a laboratory for aPCRtest.

A better way for doctors and paramedics in the field to be able to tell, for a particular patient, which drugs the infection is resistant to would thus be welcome.
