00000000Except for the outbreak in Lashio in the northern part of Shan State in 1975, all outbreak occurred in areas were A. aegypti breeds(13). In 1975 it was reported that A. aegypti did not greed in places above an altitude of 2700 feet above sea level. An entomological survey carried out in June 1977 in Loikow, the capital of Kayah State, situated at 1938 feet above sea level, showed A. aegypti breeding on the outskirts of the town with A. albopictus inside the town. Although the 1975 outbreak of DHF in Lashio was not severe, evidence was obtained that DHF could occur through transmission by A. albopictus.
