Knowledge and attitudes in Puerto Rico concerning dengue prevention.

OBJECTIVE: Dengue has been endemic in Puerto Rico for three decades. Multiple educational and community-based efforts have been developed to inform the population about dengue prevention. We undertook this study to understand the community members' knowledge, attitudes, and practices related to dengue prevention and to elicit their ideas for future prevention campaigns. METHODS: A qualitative study based on grounded theory analysis was conducted between February and May of 2001. The study involved a total of 34 participants in four group interviews who had been identified through the Puerto Rico dengue surveillance system. RESULTS: In general, participants had correct knowledge about dengue prevention, but they did not associate the mosquitoes inside their houses with Aedes aegypti. Participants insisted that "neighbors" needed to control larval habitats, and the participants also asked the Government to fumigate. CONCLUSIONS: The patterns of knowledge and opinion that emerged in the discussions can be arranged along an axis going from high levels of correct knowledge to low levels of correct knowledge about dengue and dengue hemorrhagic fever and related practices. There were few participants at either extreme. Three themes explained these patterns: misconceptions about dengue (based on previously delivered information), the "invisibility" of dengue (as compared to other diseases), and responsibility (individual and Government). Four strategies for preventive behaviors were recommended: developing community groups to identify community priorities on prevention, developing volunteer groups to deliver prevention messages, making house visits to demonstrate specific control measures, and conducting a complementary media campaign to support these strategies.

Dengue severity in the elderly in Puerto Rico.

OBJECTIVE: Severe dengue affects all age groups in the Americas, but little detailed information is available about this disease in the elderly. The objective of this article is to describe the disease in this age group. METHODS: We reviewed suspected dengue-case investigation forms submitted with diagnostic samples as well as clinical reports from infection control nurses in Puerto Rico, for the period of 1994 through 1999. RESULTS: We assigned the laboratory-positive case-patients to four age groups: infants (1 year: 554), youth (2 to 18 years: 6 857), adults (19 to 64 years: 9 433), and elderly (>/= 65 years: 822). Regardless of infecting serotype, the elderly were more likely to have been hospitalized (48% vs. 33%) (P < 0.01) and were less likely to show hemorrhage (26% vs. 33%) (P < 0.01). On multivariate analysis, controlling for gender and the presence of hemorrhage, the elderly had a higher risk for hospitalization and death than did the youths and the adults. CONCLUSIONS: The elderly appear to be more likely than youth and younger adults to develop severe illness when infected with the dengue virus, in a pattern similar to that of infants. The clinical evaluation of elderly patients with dengue must include a careful assessment of increased capillary permeability and occult hemorrhage in order to avoid complications from delayed identification and treatment of severe dengue infection. These findings are of increasing importance for dengue epidemiology and medical care in view of the expanding nature of dengue and dengue hemorrhagic fever in a world that also has a growing number and proportion of elderly persons.

The reappearance of dengue-3 and a subsequent dengue-4 and dengue-1 epidemic in Puerto Rico in 1998.

In January 1998, dengue-3 (DEN)-3 (group III genotype) was detected in Puerto Rico after an absence of 20 years. Public health officials intensified education efforts to promote community participation in dengue control. Virologic surveillance revealed an unexpected paradox: DEN-4 and DEN-1 produced a large epidemic overlaying the DEN-3 epidemic. In 1998 there were 17,000 reported cases of dengue (4.8/1,000 persons), and among all virus isolations (n = 960), DEN-4 (419, 43.6%), DEN-1 (337, 35.1%), and DEN-2 (143, 14.9%) were detected much more frequently than DEN-3 (61, 6%). Age group-specific attack rates were highest for persons 10-19 years old, followed by infants less than a year of age. Nineteen fatal cases (median = 37 years old, range = 8 months to 90 years) had a positive laboratory diagnosis of dengue. Among DEN-3 cases no fatalities were documented, 50 were hospitalized, and 10 of 48 (21%) fulfilled the criteria for dengue hemorrhagic fever (four had primary infections and six had secondary infections). During 1999, DEN-3 became the predominant serotype isolated (182 of 310 isolations, 59%). The reappearance of DEN-3 and its subsequent circulation from 1999 to 2001 produced no changes in dengue incidence that could have been detected in the absence of virologic surveillance.
