A study conducted by the Collective Health Institute (ISC) of the Federal University of Bahia (UFBA) reveals that people have gained immunity after being infected with the virus.
. dengue fever have a reduced risk of zika virus transmission. The research was published on Wednesday 7 in Science. This study was also conducted in collaboration with Fiocruz Bahia and includes among its partners the School of Public Health at Yale University in the United States.
This is the first study to evaluate and illustrate that dengue immunity may be a protective factor against zika infection in human populations.
Between March and October 2015, researchers monitored 1,453 residents of the Pau da Lima neighborhood in Salvador. The data presented in the badysis show that about 73% of investigators contracted zika at the time of onset of the disease. However, there was a reduction of up to 25% in those who were able to develop antibodies after being infected with dengue fever. Among the subgroups, the reduction reached up to 44% in some of them.
Coordinated in Bahia by Professor Federico Costa, the work had the participation of Ph.D. student Nivison Nery Jr, both of whom are part of the UFBA's SAI. The pair used a new test to look for zika infections in large populations. According to the researchers' evaluation, the zika and dengue viruses share several genetic similarities and have the habit of circulating in the same regions.
The study suggests that there was immunity in people infected with zika virus, which may explain
"The zika pandemic has generated a high overall immunity rate at this virus in the Americas, which will be an obstacle to epidemics in the coming years, "said Professor Federico Costa. . The professor also badyzes that studying both viruses can help understand the impact of vaccines, such as dengue fever and other health initiatives aimed at fighting these diseases.
