An outbreak of dengue 4 occurred in the Yucatan, México in 1984.
During the course of the outbreak, 538 of 5486 reported cases of dengue-like illness were studied; 200 were confirmed as dengue serologically and/or virologically.
Dengue 4 virus was isolated from 34 patients and dengue 1 from one.
Severe haemorrhagic symptoms were observed in 9 laboratory confirmed patients, including four deaths.
Thus, the outbreak in Yucatan is the second dengue epidemic in the Americas after the Cuban epidemic in 1981 in which a number of patients suffered from haemorrhagic complications.
It was notable that 5 of 9 hospitalized, severe cases were young adults and that only one met the WHO criteria of DHF, in contrast to primary pediatric nature of DHF in Southeast Asia.
