A new study affirms that a & # 39; Zika defense protection



In 2015, 73% of the people living in an unfavorable favela neighbor Pau da Lima, in Salvador de Bahía, Brazil, grew up with him. Zika virus. This area was so large that the disease was in the north east of the country, and Strongly emerged that has been a research issue with the scientific community. In the community that is Infected with Zika, there was a lower risk of infection of viruses of virus-related virus protection, according to a paper published in the journal.

"This study is the first one that shows that the anti-dengue defense can protect Zika's disease in human numbers," said Derek Cummings, a researcher at the University of Florida and the main author of the work.

In previous jobs, their scientific community had given evidence about this opportunity. Now, the sciences relied on the data of 1,453 residents in Pau da Lima that Zika revealed during the breakdown in 2015, which was inspected in the long term as part of a health check in urban slums.

The team has a G3 immunoglobulin measure, which is a. Responding to the main protein in Zika, a test designed to ad hoc & # 39; and painted. To do this, blood samples were used before, during and after the Zika break. Although the survey area was less than one quarter of a square kilometer, researchers found a Zika standard of 73 per cent, but a great change in the risk of disease over a short distance. Depending on environmental features such as mosquito breeding sites, levels of disease were 29 to 83 percent.

Then, the team inspected a sub-group of 642 residents surveyed for another dengue disease and investigated their Zika risk. In particular, the test evaluated the extent of antibodies that the blood partners had in the face of dengue.

Out of the 642 samples, 86% were positive for dengue, and for humans with this immune, there were two antibodies in the prevalence of a 9 per cent reduction in Zika's disease risk.

On the other hand, participants who had a recent illness due to dengue were more likely to be Zika. Scientists can value several definitions that may be possible. One of them, the defensive antibodies are still not being developed or there is something that has the protection systems of those people that increase Zika's risk. Additionally, those mosques that donate dengue also have a & # 39; Zika, and so dengue's disease simply means that Zika interference is also active.

"Although Zika has undoubtedly affected, Zika's pandemic has created high levels of protection in America, which will be a barrier to the years ahead," Cummings ends . Even, Ernesto T.A. Marques, from the University of Pittsburgh and Fundação Oswaldo Cruz in Brazil, "the work allows them to explore in the future to assess whether new anti-dengue vaccines could be useful to prevent Zika disease. "

Along with the University of Florida, the University of Pittsburgh, the Yale Public Health School, the University of Texas, the University of California (the United States), Federal Federal Bahia University, the University of Pernambuco, and the University of Pittsburgh have participated in the research.
