Abstract
Travellers' malaria is an exciting topic. It is a field in flux with evolving options for chemoprophylaxis, self-diagnosis, self-treatment, risk/strategy analyses and surveillance. Ideologies vary and experts differ but debate is needed and can bring change. The launch of a new thematic series in the Malaria Journal--"Travellers' malaria"--creates an ideal forum to bring together research papers, reviews, opinion papers and commentaries, and will hopefully stimulate debate.
