Explaining Zika Virus
Zika virus is a disease spread by certain mosquitoes and sexual contact. Most people infected with the Zika virus do not have symptoms or have mild symptoms. The Zika virus is also known to cause birth defects when pregnant women contract it.
The Symptoms Zika Virus Can Cause
For some infected people, the Zika virus may not cause any symptoms. For others, they may experience fever, headache, rash, muscle and joint pain, and conjunctivitis (red eyes). Symptoms usually last up to one week and rarely require hospitalization.
Symptoms for the Zika virus are similar to other mosquito-borne illnesses such as Dengue Fever and Chikungunya. These viruses also cause fevers, aches, and rashes.
Rarely, Zika virus can trigger Guillain-Barré syndrome, neuropathy, and myelitis in older children and adults.
How Zika Virus is Spread
Zika Virus is mainly spread when a certain type of mosquito, usually an Aedes Aegypti, bites an infected person. Later, the same mosquito bites another person and spreads the viral infection. As a result, the Zika virus is usually found in countries with this particular type of mosquito.
Zika virus can also be spread through sexual contact. In fact, you may still be able to transmit the virus through sexual contact a couple of months after recovering from it.
Finally, the Zika virus is also passed from mother to fetus. This is the most concerning transmission source since unborn children can suffer severe effects from contracting the virus.
Most who contract Zika only get the virus once, so if you’ve had a laboratory-confirmed case, you won’t get it again. Fortunately, it isn’t as fatal as other diseases spread from animals, like rabies, but we’ll look into who needs to be the most careful about the Zika virus below.
Places Where Zika Virus Is Prevalent
You’re most likely to contract the Zika virus in regions where the Aedes Aegypti mosquito lives or through sexual contact with a partner infected with the virus. The mosquito thrives in warm, moist climates in the tropical and subtropical regions of the world.
Countries with Zika Virus
Outbreaks have occurred in Southeast Asia, Europe, Africa, North and South America, and the Pacific Islands. Countries with moist, warm climates are the most likely to have Zika virus transmission.
Besides regions with documented outbreaks of Zika virus, there are other areas where the Aedes Aegypti mosquito lives. These areas include other parts of North and South America, Australia, Asia, Europe, and Africa. These regions therefore also have the potential for an outbreak.
The most up-to-date list of countries with Zika virus transmissions can be found through the CDC. Keep in mind that there are delays between transmission, detection, and then reporting.
Zika Virus in the United States
Currently, there are no documented cases of local Zika virus transmission in the United States. Since 2019, there have been no reported cases of the Zika virus in the United States. It’s still a good idea for travelers to protect themselves from mosquito bites.
Travel Restrictions Due to Zika Virus
There are no travel restrictions in place due to the Zika virus. The risk for Zika virus complications in the general population is very low. The greatest travel concerns will be for pregnant or soon-to-be pregnant women and their partners.
How to Avoid Zika Virus While Traveling Abroad
All travelers are recommended to take preventative measures like wearing long-sleeve clothes and using insect repellent in areas where the Zika virus can be transmitted.
Pregnant women, soon-to-be pregnant women, and their partners should take extra care against contracting or spreading the Zika virus through mosquito bites and sexual contact, since the Zika virus can be transmitted to the baby and there is no current vaccine.
Precautions for Pregnant or Soon-to-be Pregnant Women
Pregnant women or those planning to become pregnant should be aware of the risks that Zika virus poses to the fetus. Do not travel to regions with the potential for Zika virus. Avoid these regions during pregnancy and two months before becoming pregnant.
Use condoms as protection or avoid sexual contact with any partner who has traveled to these areas.
Precautions for Partners of Pregnant or Soon-to-be Pregnant Women
Partners can spread the Zika virus for a couple of months after recovering from the virus. Avoid sexual contact or use a condom with your partner during pregnancy. The male partner should wait at least three months before conception to prevent fetal complications.
What to Do If You Get the Zika Virus Abroad
If you are traveling in a region where multiple mosquito-borne illnesses are spreading, you may need a medical provider to determine which virus has infected you. Urine and/or blood tests are used to confirm suspected cases of the Zika virus.
Since illnesses like the Zika virus can strike while traveling, make sure you have the medical insurance coverage you need abroad. For travelers making shorter trips, always consider a travel insurance plan to cover financial costs of illness and medical emergencies on your trips.
Treatment for Zika Virus
Currently, there are no medications or vaccines for Zika virus. If you have contracted Zika virus, speak with your healthcare provider for the best advice on recovery. Avoid sexual contact and areas with mosquitos to prevent transmission.
The Effects of Zika Virus During Pregnancy
The Zika virus may cause congenital Zika virus infection, which may harm the fetus. This congenital infection is known to cause birth defects and other risks. This doesn’t mean a baby whose mother had Zika virus while pregnant will have defects, but the baby has a significantly increased risk.
Congenital Zika virus infection occurs when a pregnant mother is infected with the Zika virus and passes the infection to her fetus. Pregnant or soon-to-be pregnant travelers and expats of affected countries need to take precautions or alter travel plans.
Congenital Zika virus infection may result in pregnancy loss, stillbirth, and premature birth in addition to congenital birth defects. Research on the impact of congenital Zika virus infection and its effects is ongoing.
Birth defects include microcephaly and other brain defects. The exact risk for effects from congenital Zika virus infection is unknown. Children born with these defects will have lifelong complications.
Some of these complications include microcephaly, where part of the skull has collapsed, pigment changes and damage to the back of the eye, and restrictions to movement. Restriction to movement soon after birth can be caused by rigid muscles or joint problems like clubfoot.
Many studies regarding congenital zika virus infection came from Brazil, where residents and travelers were hit hard by the outbreak in 2015. These studies showed that children with a congenital Zika virus infection might also develop microcephaly after birth.
Frequently Asked Questions
Is the Zika virus still a travel concern?
Zika virus is a travel concern. In February 2025, the Pan American Health Organization (PAHO) revealed that 333 Zika cases were confirmed in Brazil, Bolivia, Colombia, Costa Rica, El Salvador, Guatemala, Mexico, and Peru. Take extra precautions by wearing long-sleeve clothes and insect repellent.
Does the Zika virus matter in every trimester of pregnancy?
Zika virus may cause birth defects and congenital defects in any trimester of pregnancy. It is recommended that pregnant or soon-to-be pregnant women avoid regions with active outbreaks and sexual contact with anyone who has traveled to those areas.
How do you know if a mosquito bite will spread Zika?
Mosquito bites that result in Zika virus infection look similar to any other mosquito bite. In fact, you may be infected and never develop symptoms. You will still be contagious through sexual contact, even if you do not have symptoms.
Conclusion
Zika virus risk to the general population is low. Travelers should make sure they know the current transmission information for any region they visit. Wear protective clothing and repellent to prevent mosquito bites, and use protection for sex.
The biggest risk is to unborn children. Pregnant women, soon-to-be pregnant women, and their partners can take precautions to protect the fetus from the congenital risks of the Zika virus. Speak with your doctor about your travel plans and precautions.

What are the best practices for expats to maintain mental well-being while dealing with the stress of living in a Zika-affected area? Are there any local remedies or traditional practices that expats should be aware of when it comes to preventing mosquito bites in Zika-prone regions?
To maintain mental well-being while living in a Zika-affected area, expats can reduce stress by staying informed about prevention, practicing mindfulness, and maintaining a balanced lifestyle with regular exercise and social interactions. Preventing mosquito bites is key, and local remedies such as burning citronella candles, applying neem oil, or using eucalyptus-based repellents can complement standard measures like wearing long-sleeved clothing and using insect screens. Additionally, adopting traditional practices like sleeping under mosquito nets and planting mosquito-repellent herbs, such as lemongrass or marigold, can be effective.
