Ask The Doctor Zika Virus Risk Pregnant Women In US

Overview

Zika is a virus that is mainly spread by mosquito bites. Most people who get Zika feel fine or have only mild symptoms. However, if a woman gets Zika while she is pregnant, the virus can harm the baby's developing brain and cause serious birth defects. This is why Zika is a concern for pregnant women, especially if they travel to areas where the virus is present.

Zika is not common in the United States itself, but outbreaks have occurred in parts of Central and South America, the Caribbean, the Pacific Islands, and some parts of Africa and Asia. For people in the US, the main risk comes from traveling to those areas or having sex with someone who has traveled there.

Zika can affect anyone of any age. The groups most at risk are pregnant women (because of the danger to the unborn baby) and travelers who go to areas with active Zika outbreaks. It is also possible for a man to carry Zika and pass it to a woman through sex, even if the man has no symptoms.

Symptoms

Common symptoms

• Fever
• Rash
• Joint pain, especially in the hands and feet
• Red or painful eyes (conjunctivitis)
• Headache
• Muscle pain
• Feeling very tired

Causes

Main causes

• The Zika virus, which is carried by Aedes mosquitoes. When an infected mosquito bites you, the virus enters your blood.
• From a pregnant woman to her unborn baby during pregnancy or at birth. This is the most serious way Zika causes harm.
• Through sexual contact with a person who has Zika, even if that person has no symptoms.
• Very rarely, through a blood transfusion or organ transplant.

Risk factors

• Living in or traveling to an area with active Zika outbreaks
• Not using insect repellent or mosquito nets in high-risk areas
• Having unprotected sex with someone who has been in a Zika-affected area
• Being pregnant, because the virus can harm the developing baby

When to see a doctor

See a doctor urgently if:

• If you are pregnant and have visited an area where Zika is present, or you have had sex with someone who has, see a doctor right away for advice and testing, even if you feel healthy.
• If you develop a fever, rash, joint pain, or red eyes within two weeks of traveling to a Zika-affected area.

Book a routine appointment if:

• If you are planning a pregnancy and have recently traveled to a Zika-affected area, talk to your doctor about when it is safe to try to conceive.
• If you have been exposed to Zika but have no symptoms, a routine check-up can help answer your questions and reduce worry.

Diagnosis

To diagnose Zika, a doctor will ask about your symptoms, travel history, and any possible exposure from a partner. They will also ask about your pregnancy if relevant. Because many people have no symptoms, the diagnosis often depends on a blood or urine test.

Tests that may be done

• Blood test to look for the Zika virus or antibodies (proteins your body makes to fight the virus)
• Urine test, which can detect Zika in the first two weeks after symptoms start
• For pregnant women, an ultrasound scan to check the baby's brain development and growth

What to expect at your appointment

If you go for a Zika test, the doctor or nurse will take a small sample of blood or urine. It may take several days to get results. If you are pregnant, your doctor may recommend ultrasound scans over the following weeks to monitor the baby, even if the test is negative. This is a routine precaution, not a cause for alarm.

Treatment

There is no medicine that can cure or kill the Zika virus. Treatment focuses on relieving symptoms, resting, drinking plenty of fluids, and letting your immune system fight off the infection. If you are pregnant, your doctor will closely monitor your pregnancy and the baby's development.

Self-care at home

• Get plenty of rest to help your body recover.
• Drink fluids to stay well hydrated.
• Take pain relievers or fever reducers that your healthcare provider or pharmacist recommends. Always ask first, especially if you are pregnant.
• Avoid mosquito bites so you do not spread the virus to other people. Stay indoors and use repellent and protective clothing.

Medical treatments

Medical care for Zika is mainly supportive. A doctor may recommend safe over-the-counter options to manage fever or aches. For pregnant women, care includes regular ultrasounds and check-ups with an obstetrician. In the rare case of complications like Guillain-Barré syndrome, hospital care and physical therapy may be needed.

When is surgery considered?

Surgery is not used to treat Zika. The virus itself does not require an operation. However, in rare cases where a baby is born with severe brain defects related to Zika, that baby may need surgical care for other health issues, but that is not something you would decide now. Your healthcare team will guide you.

Living with this condition

If you have Zika, you can recover at home. Stay inside, rest, and avoid mosquito bites to keep from spreading the virus to others. If you are pregnant, attend all your prenatal appointments and follow your doctor's advice about tests and ultrasounds. It is normal to feel worried, but try to focus on the steps you can take now to stay healthy.

Lifestyle tips

• Use insect repellent on your skin and wear long sleeves and pants when outdoors.
• Sleep under a mosquito net if you are in an area with mosquitoes.
• Use condoms during sex, or avoid sex, if you or your partner recently traveled to a Zika area. This is especially important during pregnancy.
• Stay active and eat well to help your body stay strong.

Diet and exercise

Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins helps support your immune system. Light exercise, such as walking or gentle stretching, is usually fine once you feel up to it. Always ask your doctor before starting any new exercise, especially during pregnancy.

Mental health and emotional wellbeing

Worrying about Zika, especially during pregnancy, can cause real stress and anxiety. It is completely normal to feel this way. Talk to your partner, family, or a counselor about your feelings. If anxiety becomes overwhelming or makes it hard to sleep or eat, reach out to your doctor for support.

Prevention

Yes, you can take steps to prevent Zika, in two main ways: avoid mosquito bites and avoid unprotected sex with someone who may have been exposed. If you are pregnant, the UK NHS recommends avoiding non-essential travel to areas where there is a current Zika outbreak. If you must travel, talk to your doctor before you go and take strict mosquito precautions.

Vaccines

There is currently no vaccine to prevent Zika. Scientists are working on one, but it is not available yet.

Screening programmes

If you are pregnant and think you may have been exposed to Zika, ask your doctor about blood or urine testing. Routine screening is not offered everywhere, but your doctor can decide if it is needed based on your travel history and symptoms. Prenatal ultrasound scans can also help monitor the baby's development.

Complications

If left untreated

• In pregnant women, Zika can cause a serious birth defect called microcephaly — the baby's head and brain are smaller than expected.
• Zika during pregnancy can also lead to miscarriage, premature birth, or other brain and eye problems in the baby.
• Congenital Zika syndrome is the term for the group of health problems seen in babies infected before birth.
• Rarely, in adults, Zika can trigger Guillain-Barré syndrome, a condition that causes temporary muscle weakness.

Long-term outlook

Most people who get Zika recover completely within a few weeks and have no long-term problems. For pregnant women, the risk is real, which is why prevention is so important. But many babies born to mothers who had Zika during pregnancy are healthy. With good prenatal care, regular scans, and the support of your healthcare team, you can take steps to give your baby the best chance. If problems are found, early support services and therapies can make a big difference.
