The Zika virus: What we know and what we don’t

Wednesday, August 17th, 2016

We know that…

  • Zika infection during pregnancy can be passed to your baby. It can cause a birth defect called microcephaly and other brain problems. Also, Zika may be linked to miscarriage and stillbirth, hearing and vision problems, and joint issues.
  • the Zika virus is spread mostly through the bite of an infected mosquito, but it also can be spread by having sex with someone who is infected, and possibly through blood transfusions. Zika can be spread through laboratory exposure in a health care setting, too.
  • the mosquitoes that live in many parts of the U.S. are capable of spreading the virus if they become infected. They become infected by biting someone who has the virus. At this time, in the continental United States, mosquitoes are spreading the virus in only one area of Florida.
  • infected mosquitoes spread the virus by biting people. Roughly 4 out of 5 people who get the Zika virus don’t have any signs or symptoms and aren’t aware that they have the virus.
  • by applying bug spray/lotion for 3 weeks after you return from a Zika-affected area, or if you were diagnosed with Zika, you will help prevent the spread of Zika to others.

 We don’t know…

  • how often Zika causes microcephaly or birth defects when a baby is exposed to the virus in the womb.
  • if or when mosquitoes in other areas of the U.S. may become infected with Zika and consequently start spreading the virus.
  • when a vaccine will be available.

Here’s what you can do

The March of Dimes #ZAPzika campaign provides essential information on Zika protection that everyone should follow and share:

  1. Use spray, keep mosquitoes away: make sure it’s EPA registered, and contains at least one of mosquito_3Dthe following ingredients: DEET, Picaridin, oil of lemon eucalyptus, para-menthane-diol, or IR3535, which are safe to use during pregnancy. Don’t use products that contain oil of lemon eucalyptus or para-menthane-diol on children younger than 3 years. When applying, always follow the product label directions;  do not put bug spray/lotion under your clothes, and put sunscreen on first (then bug spray/lotion over sunscreen). Find a repellant that is right for you.
  1. Say you will, embrace the chill: use air conditioning and window screens if possible. Repair holes on screens.
  1. If it’s wet, it’s a threat: remove still water. Mosquitoes can breed in tiny amounts of water. To prevent water from pooling and becoming mosquito breeding grounds, the CDC says “Once a week, empty and scrub, turn over, cover, or throw out items that hold water, such as tires, buckets, planters, toys, pools, birdbaths, flowerpots, or trash containers.”
  1. Get protected, not infected: wear clothes to prevent bites, such as long pants, a long-sleeved shirt, socks, shoes, and a hat. If you or your partner may be infected with Zika, use a barrier method (like a condom) every time you have sex or don’t have sex at all.
  1. If you suspect, then connect: call your health care provider if you are at risk of infection, or if you think you may have the Zika virus.

If you are thinking about getting pregnant, CDC guidelines suggest waiting at least 6 months from the first sign or symptom if a male partner was diagnosed with the virus, and waiting at least 8 weeks from the first sign or symptom if a woman tested positive for Zika.

If you or your partner may have Zika but neither of you have signs or symptoms and neither of you has been tested, wait at least 8 weeks from when you think you may have been exposed to Zika before trying to get pregnant. Keep in mind that research is ongoing to confirm these waiting times.

The Zika virus may stop brain development causing microcephaly and birth defects

Wednesday, June 22nd, 2016

mosquito_3DWhen a woman is pregnant and is infected with the Zika virus, it may cross the placenta and may stop the development of a baby’s brain. Zika infection during pregnancy causes a birth defect called microcephaly as well as other brain problems known as “fetal brain disruption sequence.”

Microcephaly means small (micro) head (cephaly) – a baby’s head is smaller than the heads of babies of the same age and sex. Microcephaly does not always cause serious problems for a baby. But in certain cases, microcephaly can cause lasting consequences, such as intellectual and developmental disabilities. Babies born with microcephaly may have cerebral palsy, poor growth, face deformities, feeding problems, seizures, problems with hearing or vision, and hyperactivity. They may face life-threatening medical conditions. Microcephaly caused by the Zika virus may be severe and is extremely concerning.

There is no cure for microcephaly. Babies with microcephaly will need regular medical check-ups and follow up care. Many will need specialized treatment by doctors such as a neurologist, developmental and behavioral pediatrician, and rehabilitation specialists. Early intervention services for babies and toddlers as well as special education services for children ages 3 and older, may be essential in helping a child develop.

Fetal brain disruption sequence refers to the halting of the development of a baby’s brain as a result of being exposed to the Zika virus. This stop in development can result in a wide variety of health problems for the baby, which can be lifelong.

The Zika virus may also be linked to growth problems in the womb, miscarriage and stillbirth.

Vaccine progress

Currently, there are no FDA-approved vaccines to prevent Zika. But, the FDA (The US Food and Drug Administration) has approved the first Zika vaccine study in human volunteers, ahead of schedule. Clinical trials should begin in the next few weeks. Although this is great news, it could take years before a safe vaccine is available to the public.

How can you stay safe?

The Zika virus is real and dangerous. Until a vaccine is available, learn all you can about how to stay safe.
