Of the three diseases described in this communication, yaws and cutaneous leishmaniasis are prevalent in many parts of both hemispheres. Pinta is largely confined to the American tropics. Few members of our armed forces are liable to contract either yaws or pinta, as these diseases are due to lack of personal hygiene and are not usually acquired through insect vectors. However, our medical officers in certain tropical regions will doubtless have to render medical aid to native populations and will then see many cases of these diseases.
Cutaneous leishmaniasis is, however, contracted both by personal contact and by the bite of one of several species of Phlebotomus or occasionally of other insects. It is therefore probable that some of our armed forces will be infected by this disease.
Yaws and pinta are confined almost exclusively to the tropics, whereas cutaneous leishmaniasis is seen in both tropical and semitropical regions.
