Abstract

Summary

An epidemiological investigation revealed that in a district of the Province of Teramo (Abruzzo, Italy), 23.7 per cent of the population showed either active lesions or the scars of oriental sore. Two subsequent annual applications of residual DDT inside houses and stables were sufficient to stop the transmission of the disease. The porportions of new cases in the treated zone were 7 per thousand after the first, and 1.3 per thousand after the second application of DDT, compared with 34.7 and 40.4 per thousand respectively in the untreated zones.

After the first DDT spraying had disappeared, with an occasional exception, and after the second treatment no at all was observed either indoors or outside in the treated zone, while these insects continued abundant in the untreated areas.
