Pregnant Woman Tests Positive For Zika Virus In India: How To Protect Fetal Health And Prevent Damage

Add as a preferred source on Google

The number of Zika virus cases is increasing rapidly, with a pregnant woman in Erandwane, Pune recently testing positive for the virus. In the past 10 days, five cases have been reported in Pune. The woman is currently receiving treatment, and her sonography report in May showed no abnormalities in the fetus.

According to the World Health Organisation (WHO), most people infected with the Zika virus do not develop symptoms. Those who do may experience rash, fever, conjunctivitis, muscle and joint pain, malaise, and headache lasting 2-7 days.

Let us know how to prevent fetal damage if a pregnant woman tests positive for Zika virus.

What You Need To Know About Zika Virus

The Zika virus, first identified in Uganda in 1947, remained relatively obscure until significant outbreaks occurred in Brazil and other parts of the Americas in 2015-2016. The virus is primarily spread through the bite of an infected Aedes species mosquito, but it can also be transmitted through sexual contact and from a pregnant woman to her fetus. While Zika infections in adults often result in mild symptoms, the virus poses a severe threat to developing fetuses. The devastating effects of Zika on fetal health underscore the importance of understanding this virus and taking preventive measures.

The Zika virus has been linked to a range of birth defects and developmental issues, most notably microcephaly, a condition where a baby's head is much smaller than expected due to abnormal brain development. This article explores the impact of Zika on fetal health and provides essential tips for preventing fetal damage, emphasizing the need for vigilance and proactive measures.

How Zika Virus Affects The Health Of A Fetus

1. Microcephaly and Brain Abnormalities
Microcephaly is the most well-known and severe birth defect associated with Zika virus infection during pregnancy. Babies born with microcephaly have smaller heads and brains, leading to significant neurological impairments. The virus attacks neural progenitor cells in the developing brain, disrupting normal brain growth and leading to a smaller, malformed brain structure.

2. Congenital Zika Syndrome
Congenital Zika Syndrome (CZS) encompasses a spectrum of health issues beyond microcephaly. It includes brain abnormalities, eye defects, hearing loss, and impaired growth. Babies with CZS often suffer from severe developmental delays, seizures, and problems with movement and balance.

3. Eye Defects
Zika virus can cause a range of eye defects in infants, including retinal damage, cataracts, and optic nerve abnormalities. These defects can lead to vision problems or blindness, significantly affecting the child's quality of life.

4. Joint and Limb Defects In some cases, Zika can cause joint and limb abnormalities, such as clubfoot or arthrogryposis, where joints are permanently fixed in a bent or straightened position. These physical deformities can complicate mobility and require long-term medical intervention.

5. Hearing Impairments
Zika virus infection during pregnancy can lead to hearing impairments in the newborn. The virus affects the structures of the inner ear, resulting in partial or complete hearing loss. Early detection and intervention are crucial for managing hearing impairments and supporting language development.

6. Growth Restrictions
Intrauterine growth restriction (IUGR) is another consequence of Zika infection. Babies affected by IUGR are smaller than expected for their gestational age, which can lead to a range of health issues at birth and later in life, including difficulties in feeding, temperature regulation, and increased susceptibility to infections.

Prevention From Zika Virus And Protecting Fetal Health

1. Avoid Travel to Zika-affected Areas
   One of the most effective ways to prevent Zika infection during pregnancy is to avoid travel to areas with known Zika outbreaks. Pregnant women or those planning to become pregnant should stay informed about current Zika virus hotspots and avoid unnecessary travel to these regions.

2. Mosquito Bite Prevention
   Since mosquitoes are the primary vectors for Zika virus transmission, preventing mosquito bites is crucial. Pregnant women should use EPA-registered insect repellents, wear long-sleeved shirts and long pants, and stay in places with air conditioning or window and door screens to keep mosquitoes out. Sleeping under mosquito nets can also provide added protection.

3. Eliminate Mosquito Breeding Sites Reducing mosquito populations by eliminating standing water around homes is essential. Mosquitoes lay eggs in stagnant water, so regularly emptying, cleaning, or covering containers that hold water can significantly decrease mosquito breeding sites. This includes items like flower pots, buckets, birdbaths, and gutters.

4. Safe Sexual Practices
   Zika can be transmitted through sexual contact, so practicing safe sex is important, especially if one partner has traveled to a Zika-affected area. Using condoms consistently and correctly can reduce the risk of sexual transmission of the virus.

5. Regular Prenatal Care
   Pregnant women should attend regular prenatal check-ups to monitor their health and the development of the fetus. Early detection of any abnormalities can lead to timely interventions and better outcomes. If a woman suspects she has been exposed to Zika, she should inform her healthcare provider immediately.

6. Community Awareness and Education
   Raising awareness about Zika virus and its risks, especially among pregnant women, is vital. Community education programs can help spread information about preventive measures, symptoms of Zika infection, and the importance of seeking medical advice if exposure is suspected.

7. Environmental Control Programs
   Governments and public health organizations should implement and support environmental control programs to reduce mosquito populations. This includes spraying insecticides in areas with high mosquito densities and implementing public awareness campaigns about eliminating breeding sites.

8. Use of Zika Vaccines
   While there is currently no vaccine available to prevent Zika virus infection, research is ongoing. Pregnant women should stay informed about developments in Zika vaccine research and be ready to take advantage of any future vaccines once they become available.

9. Surveillance and Monitoring
   Continuous surveillance and monitoring of Zika virus activity can help identify outbreaks early and implement control measures promptly. Public health authorities should maintain robust monitoring systems to track the spread of the virus and provide timely updates to the public.
