In a study of the incidence of mosquito-borne haemorrhagic fever in Thailand, marked differences were found between the patterns in areas north and south of the Kra Isthmus. In the north, the peak of incidence follows the beginning of the rainy season and of mosquito breeding by about 2 months each year. In the south, where rains all the year round permit continuous breeding, there is no seasonal upsurge of the vector populations or of the fever. Aedes aegypti (L.) and A. albopictus (Skuse) are the species involved, the former being the more effective vector. A. aegypti is common in urban habitats, while A. albopictus occurs in areas away from man, and was more frequently found biting outdoors. Control strategies in the northern and southern parts of Thailand are discussed.
