RESUMO
Ae. aegypti was reintroduced into Panama in 1985; control was unsuccessful and by 1988 Ae. aegypti larvae were detected in every borough of Panama Metropolitan Area. Only 3% of the Panama City population has dengue antibody (against DEN 2) and virtually no one is immune to other serotypes. The relative risk of the introduction of Dengue virus into Panama is discussed.

We report transovarial transmission of Gamboa virus (Bunyavirus) in Aedeomyia squamipennis, a tropical mosquito which is active and bloodfeeding throughout the year. Gamboa virus was isolated during each of the 28 months of the study from every mosquito stage, including eggs, demonstrating that vertical transmission is a maintenance mechanism of this virus. The overall minimum infection rate was 5.1/1,000 mosquitoes. Identification of the 567 isolates by neutralization indicated that greater than or equal to 2 serotypes or subtypes of Gamboa virus circulate at the study site.
