Dengue haemorrhagic fever/dengue shock syndrome: lessons from the Cuban epidemic, 1981.

Dengue haemorrhagic fever/dengue shock syndrome (DHF/DSS) is one of the principal causes of hospitalization and death among children in several south-east Asian countries. Also, in the Region of the Americas, there has been an increase in the frequency of dengue fever epidemics and in the number of cases of DHF/DSS. In 1981 an epidemic of dengue haemorrhagic fever occurred in Cuba and this suggests that there is a high risk that such epidemics could recur in the region. The article summarizes the main clinical, virological, and epidemiological data obtained during the outbreak, some of which are reported for the first time.
