On the way down from Lata I had developed ugly looking ulcers around my mouth and lips.  I was worried about what was causing them, I set off to find the hospital.  It was a long walk to the hospital along the road to the airstrip.  I managed to arrive before the doctor finished for the day.  I told the doctor about my recent malaria and the drugs I was taking.  He responded that the ulcers were a common side effect of the Primaquine tablets I was taking.  The doctor gave me some multivitamin pills and said the ulcers will clear up when I finish the course of treatment.  That was a relief, it wasn’t some flesh-eating tropical disease.
