What Is Zika Virus?
The Zika virus is a disease spread by Aedes mosquitoes. Most people don’t show any symptoms. When symptoms occur, they are usually mild. Common signs include fever, rash, and joint pain. The Zika virus poses significant risks, especially for pregnant women. Infection during pregnancy can lead to serious congenital disabilities. Microcephaly, a condition where babies are born with small heads, is a concern. The virus can also spread through sexual contact and blood transfusions. Currently, there is no specific treatment or vaccine for Zika. It’s essential to take preventive measures to avoid mosquito bites and potential exposure.
What are the Symptoms of Zika Virus?
Zika virus infection is often mild, and some people may not notice any symptoms at all. When symptoms do appear, they typically start 2–7 days after being bitten by an infected mosquito. Common signs include:
- Red eyes (conjunctivitis)
Because these symptoms are similar to other viral infections like dengue or chikungunya, it can be hard to identify Zika on your own. If you experience these signs, especially after travel to an area with Zika transmission or mosquito exposure, it is important to consult a doctor promptly. Early medical evaluation can help confirm the infection, monitor for complications, and provide guidance on care, particularly for pregnant women, since Zika can affect fetal development.
What Causes Zika Virus?
The Zika virus is primarily transmitted through the bite of an infected Aedes aegypti mosquito, which becomes contagious after biting a person carrying the virus. If you are bitten, symptoms such as mild fever, rash, joint pain, red eyes, or fatigue can appear within 2–7 days. While many infections are mild, it is important to visit the nearest hospital promptly for evaluation, especially if you are pregnant or have underlying health conditions.
Zika can also be transmitted sexually, even if the infected person does not currently show symptoms or after symptoms have subsided. This means the virus can inadvertently spread to partners, making prevention and early medical consultation critical. Timely guidance from a doctor ensures proper monitoring, reduces the risk of complications, and helps prevent onward transmission to others.
The Aedes aegypti, also known as the Yellow Fever Mosquito, is the main carrier of the Zika virus. It is small (4–7 mm), dark in colour, and easily identified by its white-striped legs and a lyre-shaped marking on its thorax. Unlike most mosquitoes, it is a daytime biter that prefers humans, often targeting ankles and elbows. This species usually lives indoors, resting in dark corners, and breeds in small containers of clean, stagnant water like flower pots, buckets, or discarded tyres.
How Did The Zika Virus Affect India?
In the year 2024, a concerning total of 151 cases of Zika virus disease (ZVD) were reported across three states in India: Gujarat, Karnataka, and Maharashtra. The majority of these cases, 140, were recorded in Maharashtra alone through the Integrated Disease Surveillance Programme (IDSP). Meanwhile, Karnataka reported ten cases and Gujarat noted one case.
The increasing number of cases, especially in the past year, requires ongoing monitoring and improved surveillance systems because the Aedes aegypti mosquito is widespread and could lead to bigger outbreaks in the future.
How to Prevent Spread of Zika Virus?
Zika virus primarily spreads through the bite of infected Aedes mosquitoes, and in some cases through sexual contact. To reduce the risk, take simple preventive measures:
- Use mosquito repellents
- Wear long-sleeved clothing
- Sleep under mosquito nets
- Drain plant pots or buckets to prevent mosquito breeding
People infected with Zika should avoid mosquito bites for at least a week to prevent passing the virus to others and practice safe sex to reduce sexual transmission. Pregnant women should take extra precautions and consult a doctor before travelling to affected areas.
Where Do I Get Zika Virus Treatment?
If you suspect a Zika virus infection, it’s important to seek treatment at a medical facility with infectious disease or general physician services. Treatment is mainly supportive, so hospitals and clinics that can monitor vital signs, manage fever and pain, and provide guidance on hydration and rest are suitable.
For those in urban areas or near large cities, it is preferable to visit a well-equipped hospital or specialised healthcare centre with access to laboratory testing for accurate diagnosis. Pregnant women or people with underlying health conditions should seek prompt care at a hospital with obstetric or specialist support to monitor any potential complications. Avoid self-medication and consult a doctor to ensure proper monitoring and advice.

Frequently Asked Questions
What is Zika virus infection (Zika)?
It is a mosquito-borne disease caused by the Zika virus, primarily transmitted to humans through the bite of an infected Aedes mosquito.
What are the symptoms of Zika?
Most people are asymptomatic. When symptoms occur, they are typically mild and include a skin rash, fever, conjunctivitis (red eyes), muscle and joint pain, malaise, and headache, usually lasting for a few days to a week.
How does the Zika virus infect people/How is Zika transmitted?
Primarily through the bite of an infected Aedes mosquito. It can also be transmitted from a pregnant woman to her fetus, through sexual contact, and rarely through blood transfusion.
What is the risk of Zika to pregnant women and women preparing for pregnancy?
Infection during pregnancy can cause microcephaly and other severe congenital brain abnormalities (Congenital Zika Syndrome) in the developing fetus and newborn, as well as pregnancy complications like fetal loss and stillbirth.
What is microcephaly?
It is a rare condition where a baby is born with an abnormally small head due to abnormal brain development. Genetic factors, infections during pregnancy, exposure to toxins, malnutrition, and maternal health issues can cause microcephaly.
What is the relationship between the Zika virus and Guillain-Barré Syndrome (GBS)?
Zika virus infection is a trigger for Guillain-Barré Syndrome, a rare autoimmune disorder where the body's immune system attacks the nerves, leading to muscle weakness and potential paralysis.
Can infection with the Zika virus be prevented?
Prevention focuses on avoiding mosquito bites (wearing long clothing, using EPA-registered insect repellent, eliminating standing water) and preventing sexual transmission (abstinence or consistent condom use).
Is there a vaccine or specific treatment for Zika?
No. There is currently no specific medicine to treat the virus, nor is there a vaccine to prevent infection. Treatment is supportive (rest, fluids, treating pain/fever with acetaminophen).
How is Zika diagnosed?
Diagnosis is confirmed through laboratory tests (e.g., PCR or serological tests) on blood or other body fluids.
Does getting Zika once confer lifelong immunity?
Yes, once a person has been infected, they are likely to be protected from future infections.
Where does infection with the Zika virus occur/Where is Zika found?
Mainly in tropical and subtropical areas with large populations of the Aedes mosquito, including parts of the Americas, Africa, Asia, and the Pacific islands.
Can a mother give the Zika virus to her unborn baby?
Yes, the virus can be transmitted from a pregnant mother to her fetus during pregnancy.
Can pregnant women use insect repellents like DEET?
Yes, EPA-registered insect repellents, including those containing DEET, are safe and effective for pregnant and breastfeeding women when used as directed.
How long should travellers returning from Zika areas abstain from sex or use condoms?
Current guidance recommends that men who travelled to a Zika risk area should use condoms or abstain from sex for at least 3 months. Women who travelled should wait at least 2 months. If a person has symptoms, the wait time is longer for men.
Can the Zika virus be transmitted through donated blood or breast milk?
It can be spread through blood transfusion (which is why precautions like deferral periods are in place). Transmission through breast milk has not been confirmed, and the benefits of breastfeeding are generally thought to outweigh the minimal risk.
Which doctor should I consult for Zika Virus?
For suspected Zika virus infection, consult a general physician or an infectious diseases specialist. Pregnant women should see an obstetrician for monitoring, and patients with complications may be referred to a neurologist or other specialists as needed.
How much does Zika Virus treatment cost?
Treatment for the Zika virus is primarily supportive, including rest, hydration, and medications for fever or pain. Costs vary depending on hospital services, diagnostics, and any specialised care required, so it’s best to contact the hospital directly for an accurate estimate.
