Via Gazeta Digital in Cuiaba, Mato Grosso state: Bebê é infectado por chikungunya durante gravidez. [Baby is infected with chikungunya during pregnancy] Edited excerpt from the Google translation:
Test results made in Paraiba confirm chikungunya transmission from a pregnant women to the fetus. Researchers say they are unaware of any similar precedent in the country. It is in a 12-day-old baby showing strong convulsions and now hospitalized in an intensive care unit in the city of Campina Grande.
The warning was given by pediatricians of the Municipal Children's Hospital and confirmed by the team of obstetrician Adriana Melo, the doctor who was also responsible for identifying the Zika virus in the amniotic fluid of two fetuses with microcephaly in 2015.
The examination was held in Campina Grande by researchers of the Professor Joaquim Amorim Neto Paraiban Research Institute (Ipesq), the Faculty of Social Sciences (FACIS), and the Federal University of Rio de Janeiro (UFRJ). Two other cases in the city are under investigation by the research group led by Adriana Melo.
There were already reports in the literature of maternal chikungunya transmission to the baby during pregnancy, says Adriana Melo. She says she is unaware, however, of proven cases of such transmission in Brazil. The examination for traces of the virus was done on both the baby and the mother.
The result strengthens the alert for pregnant women, who should take protective measures against Aedes aegypti, the mosquito vector of Zika, dengue and chikungunya, throughout the period of pregnancy.
"While the increased risk of transmission of Zika occurs in the first three months of pregnancy in the case of chikungunya is the opposite. The transmission to the fetus usually happens when the mother already ill at the end of pregnancy," said researcher Rivaldo Cunha of the Oswaldo Cruz Foundation.
