“…25 In 2000, DENV-3 serotype was introduced in Rio de Janeiro causing a widespread, 3-year outbreak. [25][26][27] Although DENV-3 was the predominant serotype and was the only serotype associated to fatalities, DENV-1 and -2 serotypes were also circulating. 26 DENV-3 virus later spread more broadly in Brazil.…”

Abstract. We have reported the epidemic patterns of dengue disease in the Region of the Americas from 1980 through 2007. Dengue cases reported to the Pan American Health Organization were analyzed from three periods: 1980-1989 (80s), 1990-1999 (90s), and 2000-2007 (2000-7). Age distribution data were examined from Brazil, Venezuela, Honduras, and Mexico. Cases increased over time: 1,033,417 (80s) to 2,725,405 (90s) to 4,759,007 (2000-7). The highest concentrations were reported in the Hispanic Caribbean (39.1%) in the 80s shifting to the Southern Cone in the 90s (55%) and 2000-7 (62.9%). From 1980 through 1987, 242 deaths were reported compared with 1,391 during 2000-7. The most frequently isolated serotypes were DENV-1 and DENV-2 (90s) and DENV-2 and DENV-3 (2000-7). The highest incidence was observed among adolescents and young adults; dengue hemorrhagic fever incidence was highest among infants in Venezuela. Increasing dengue morbidity/mortality was observed in the Americas in recent decades.

“…A study of the first dengue epidemic in Salvador, capital of the State of Bahia, showed centrifugal propagation of cases, characterizing a pattern of spread by expansion with a well-defined epicenter, similar to the process of spread by contagion and different from what usually occurs with a vector-borne disease like dengue 19,33 . A similar phenomenon may occur in the other Brazilian metropolises, inducing the occurrence of epidemics that propagate rapidly to practically the entire city, reaching significant portions of the population.…”

“…121 This serotype was introduced in Rio de Janeiro Brazil in 2000, 110 which subsequently spread to other areas of the country. 122,123 The countries with the highest incidence rates were Honduras (490 of 100,000), Trinidad and Tobago (480 of 100,000), Brazil (452 of 100,000), Costa Rica (314 of 100,000), and El Salvador (286 of 100,000). In Central America 83,179 cases were reported.…”
