Zika Virus for Fertility Patients: here’s what you need to know

We’re all frightened by what we don’t understand. Many infectious diseases feed in to that fear. Consider for example the recent media frenzy over Ebola Virus; then again over Bird Flu and then more recently over Chikungunya—all of which have died down without the nightmare scenarios coming to fruition. Now we’re focusing on Zika virus.  This is admittedly scary due to its possible link to birth defects in babies born in Brazil. So let’s review what we know, what we don’t know AND what we can do in the meantime.

Recently the Society of Maternal-Fetal-Medicine held a special session to review this important topic and provide updated advice and guidance for women’s healthcare specialists in the USA. Zika is a virus transmitted by mosquitos. Those developing a symptomatic infection during pregnancy may be at high risk of having a child with a birth defect known as microcephaly. Although this link has not yet been definitively established it is recommended that we provide very close surveillance of any suspected cases while additional information is gathered. Although this sounds scary here are some of the key facts to keep in mind:

  • Only 1 in 5 people bitten by an infected mosquito is likely to develop an infection
  • Those infected have pretty specific symptoms including sore joints, a rash and conjunctivitis (red, swollen areas around the eyes)
  • The infection will appear within one or two weeks of the mosquito bite
  • The current test available is nonspecific and can create concerns due to false-positive results (a positive test due to a related virus that has not been linked with birth defects)
  • The Center for Disease Control and Prevention is monitoring places in the world known to have active Zika transmission for travelers and advising those that are pregnant or planning pregnancy to avoid traveling to those locations
  • Meanwhile, alternate causes of the fetal malformations are being investigated including a possible link to an insecticide widely used to control mosquitos in the area of Brazil most heavily effected by fetal microcephaly

Clearly we need to learn more about the Zika virus. In the meantime, here is some practical advice for patients that want to become pregnant:

  • If possible avoid traveling to areas effected by Zika for at least one month prior to starting fertility treatment
  • During mosquito season (as well as while traveling to effected areas) consider the following protective steps
    • Wear long sleeves when possible and stay in air conditioned facilities (rather than using open windows for cooling
    • Use insect repellants to reduce the risk of mosquito bites. Here are two that are among the safest (and least toxic) for women trying to conceive:
    • If you live in an area with a high rate of Zika virus exposure, consider undergoing fertility treatment and freezing the embryos for delayed embryo transfer–a process known as embryo banking.
    • If you develop the symptoms of rash, joint pain and red eyes, contact your healthcare provider to discussed current recommendations on testing.
    • Stay informed. If you subscribe to this blog, I will do my best to remain current on this topic.

Latest Update 02/29/2016: “It’s entirely possible there’s something else going on in Brazil — something unique to the population or environment in which transmission takes place.”  – Dr. Anthony Fauci, Direct of National Institute for Allergy and Infectious disease
