TYPES
The dengue virus presents variations in its structure, which means it has different serotypes and viral lineages. To date, five serotypes and 18 lineages of the dengue virus are known. In Brazil, dengue serotypes 1, 2, 3 and 4 circulate.
After infection with a type of dengue virus, the body becomes permanently immune to that serotype. But infection with one serotype does not protect against the others. For this reason, each person can become infected with the dengue virus four times.
The predominance of one or another dengue serotype varies in different regions and over time. In this case, it depends on the dissemination capacity and the percentage of people not yet infected by that serotype.
Any of the four dengue serotypes (1, 2, 3 and 4) can produce asymptomatic infections or mild, severe cases and even deaths.
Type 1: identified for the first time in 1981, in isolated cases in Roraima. It began to circulate in other regions of the country in 1986.
Type 2: identified in 1990. Types 1 and 2 have predominated in the last four years.
Type 3: isolated in 2000 and remained the most common serotype in the country until 2016.
Type 4: identified in isolated and restricted cases in the North region in 1981, however, after 2010, it began to be identified in other parts of Brazil.
Type 5: appeared for the first time in 2007, in Malaysia, on the Asian continent. To date, no case has been identified in Brazil.
The development of severe dengue can occur with any of the types of the virus, especially after the second infection. In these cases, the immune system may react more strongly and excessively.
