Rheumatic symptoms

Pregnancy and Zika virus

  • There is an increased risk of fetal harm (mikrocephali) if a pregnant is infected, especially in the led 1 / 3 of pregnancy
  • A study of 442 infected pregnant women showed that 6% gave birth to children with injuries following Zikavirus infection (reference: Honein MA, 2017)
    • Everyone with injured children was infected during the first three months of pregnancy
    • The risk of fetal injury is independent of whether the pregnant woman has symptoms of infection or is infected without noticeable symptoms
  • Fetal injuries include brain damage, microcephaly (small head) and fetal death (reference: Brasil P, 2016)
  • Caused zika syndrome can be defined (reference: Hoen B, 2018)
    • Serious microcephaly
    • Special brain formation
    • Changes in the eye (retina)
    • Joint malformations (like lumps)
    • Spasticity
  • Due to the epidemic from 2016, the health authorities of several South American countries have asked women to postpone pregnancy to 2018 or later
