Zika virus gets longer in the body of pregnant women

Zika virus gets longer in the body of pregnant women

We know that the effects of Zika virus on pregnant women and their fetuses are very serious. However, a new study, published on Tuesday (27) in the scientific journal Nature Communications showed that this was not enough, the virus usually stays in the body of the pregnant women.

Scientists at the University of Wisconsin-Madison United States) demonstrated this through an animal study. The researchers used rhesus monkeys, which are also susceptible to virus infection and have a model closer to humans.

In the research, eight animals in the most different conditions were infected with the virus and had their blood, saliva, urine and marrow constantly examined for genetic detection of the Zika virus. The scientists then realized that in non-pregnant animals the mean time of virus presence in the body was 21 days. In the pregnant monkeys, mean time was 51 days (up to 70 days in one case). This is very problematic, since the virus in the body of a pregnant woman can cause malformations such as microcephaly in infants.

Experts are not sure why the virus stays in the body for such a long time. One hypothesis is that the presence of Zika in the mother's bloodstream indicates that the fetus is infected, and the infection in the baby is longer. However, the study also found another interesting pattern: the animals that were infected with the virus became resistant to it in a new infection made 10 weeks later, which shows a possible protection against the virus.
