Zika Avoids Protections During Early Pregnancy: What You Need to Know
The Zika virus, first identified decades ago, resurfaced as a major health concern due to its link to severe birth defects. New research now shows how the virus can evade the body’s natural protections during early pregnancy, increasing the risk to developing foetuses.
How Zika Impacts Pregnancy
During early pregnancy, the immune system typically adapts to protect the baby while keeping harmful pathogens at bay. However, scientists have found that the Zika virus can bypass these defences, infecting placental cells and potentially spreading to the foetus.
Key Findings from Recent Research
- Immune Evasion: Zika suppresses certain immune responses, allowing it to survive longer in the body.
- Placental Vulnerability: The virus can replicate within the placenta, creating a direct pathway to the foetus.
- Neurological Damage Risk: This transmission can lead to microcephaly and other developmental disorders.
Risks for Pregnant Women
Women infected with Zika during the first trimester face the highest risk of birth defects. Even mild or unnoticed symptoms in the mother can have severe outcomes for the baby.
Prevention Strategies
- Avoid travel to areas with active Zika outbreaks, especially during pregnancy.
- Use mosquito repellent containing DEET or picaridin.
- Wear long-sleeved clothing to reduce mosquito bites.
- Practise safe sex, as Zika can also be sexually transmitted.
Ongoing Research and Hope for the Future
Scientists are working on vaccines and antiviral drugs to combat Zika, though none are widely available yet. Enhanced mosquito control and public health campaigns remain critical.
Protecting Yourself and Your Baby
Staying informed and taking preventive measures is the best defence. Pregnant women should consult healthcare providers before travelling to Zika-prone regions.
