Wet weather leads to a rise in the mosquito population, says Dr Ed Sixsmith.

He said rain is the "enemy" of doctors in countries like Central African Republic, where he is currently working.

The World Malaria Report has found an estimated 437,000 African children died before their fifth birthday due to malaria last year.
