Zika virus is a type of virus, also called Zika fever, transmitted by mosquitoes of the genus Aedes. It is generally transmitted from person to person through mosquito bites, but sexual contact and mother-to-child transmission are also possible. It can cause mild symptoms in infected humans, but it can negatively affect fetal development in pregnant women and lead to birth defects such as microcephaly. Additionally, it has been associated with neurological problems such as Guillain-Barré syndrome.
Pregnant women and couples planning a pregnancy who travel to regions where the virus is prevalent must be cautious. Protection against mosquito bites, the prevention of sexual transmission, and safe pregnancy measures are important to limit the spread of this virus.
How is Zika Virus Transmitted?
Zika virus can be transmitted through several different ways, primarily by mosquitoes of the Aedes genus:
Mosquito Bites: It enters your blood when you are bitten by an infected mosquito. This is the natural cycle of the virus. When you are bitten by an infected mosquito, the virus enters the human body.
Sexual Transmission: It can also be transmitted through sexual contact. An infected person can pass the virus to his partner through sexual intercourse. Therefore, couples planning a pregnancy or pregnant women must be cautious and use protection methods.
Mother-to-Child Transmission: It can pass from a pregnant woman to her baby. This condition can cause the fetus to have birth defects and problems such as microcephaly.
Blood Transfusion and Organ Transplantation: Although rare, the blood or organ of an infected person can be transmitted from one person to another. Therefore, careful screenings are performed in blood donations and organ transplants.
Laboratory Contact: Healthcare workers or laboratory personnel working with the Zika virus can become infected when they come into contact with infected materials.
It is found endemically, especially in regions with high mosquito density, and transmission resulting from mosquito bites is the most common way. Therefore, it is important to take precautions against mosquito bites when traveling or living in these regions. It is also important to use protection methods during sexual intercourse to reduce the risk of sexual transmission.
In Which Countries is Zika Virus Seen?
Zika virus was first discovered in 1947 in the Zika Forest of Uganda. Later, starting from the 1950s, it spread to Asia, the Pacific Islands, and South America. In 2015, a major outbreak occurred in Brazil, and cases of microcephaly linked to the Zika virus increased.
The regions where this virus is prevalent may change over time. As of 2021, the countries where it is still endemic in certain regions and may pose a risk to travelers can be as follows:
- Certain regions in South and Central America,
- Certain regions in the Caribbean,
- Certain regions in Southeast Asia.
However, this information may be updated over time, so if you are considering traveling, it is important to follow current travel health recommendations and warnings. In addition, if individuals planning a pregnancy or pregnant women are considering traveling to these regions, he must be cautious and get recommendations from healthcare professionals.
How to Protect Against Zika Virus?
You can take the following precautions to protect against the Zika virus:
Protection from Mosquito Bites: Wear clothing that covers the body to protect against mosquito bites. Protect exposed skin areas with insect repellent lotions or sprays. Use tulle-covered beds or mosquito nets while sleeping.
Traveling: If you are considering traveling to regions where it is prevalent, consult travel health specialists before traveling and follow travel health recommendations.
Preventing Sexual Transmission: Use condoms or other protective methods to prevent sexual transmission, which is especially important for individuals planning a pregnancy or pregnant women.
Caution in Pregnancy: Women who are planning a pregnancy or are pregnant should avoid traveling to regions where the virus is transmitted. If he has to travel to these regions, precautions against mosquito bites and the prevention of sexual transmission must be taken.
Blood Transfusions: Check whether medical healthcare institutions use advanced screening and test methods before receiving blood or blood products.
Laboratory Work: Healthcare workers, laboratory personnel, and other relevant individuals working with the Zika virus must strictly follow safety precautions.
These precautions can help protect against the virus. These precautions are of great importance, especially during pregnancy or for individuals planning a pregnancy.
What Are the Symptoms of Zika Virus?
Symptoms are usually mild and can last 2 to 7 days. Many people experience no symptoms or have very mild symptoms. However, the symptoms of Zika virus infection can be:
- Fever,
- Rash,
- Joint and muscle pains,
- Conjunctivitis (redness of the eyes).
What Kind of Problems Does Zika Virus Cause in Pregnant Women?
The virus can cause serious problems in pregnant women. Its transmission from a pregnant woman to the fetus can negatively affect the development and health of the fetus. Some important outcomes where Zika virus infection can lead to problems associated with pregnancy:
Microcephaly: Especially when transmitted from the mother to the fetus during the early period of pregnancy, it can lead to a condition called microcephaly in the baby.
Other Associated Problems: The virus infection can lead to problems in the baby's eyes and ears, neurological problems, congenital joint contractures (joint deformities), and other birth abnormalities.
How is Zika Virus Diagnosed?
Zika virus is diagnosed with laboratory tests. The presence of the virus is detected in blood, urine, and semen. Placenta or fetal material samples can also be used. Since Zika virus symptoms are similar to other infections, diagnostic tests are important, especially for pregnant women or those with a travel history. Diagnosis and testing processes are carried out by healthcare professionals, and expertise is required in interpreting the results. In case of a suspected situation, it is important to apply to a healthcare professional.
Zika Virus Treatment
There is no specific antiviral treatment or vaccine for the Zika virus yet. Treatment for Zika virus infection is limited to symptomatic support. The following measures can be taken to relieve symptoms and support the body:
- His symptoms are usually mild, but it is important for the infected person to rest and sleep adequately.
- It is important to drink plenty of water to prevent body fluid loss and maintain hydration.
- Pain relievers or antipyretic medications can be used to relieve headache, muscle pain, and fever. However, it is important to consult a healthcare professional regarding medication use.
- Topical creams or lotions can be used to relieve itching and reduce skin rashes. However, the use of medication without consulting a doctor is not recommended.
Especially pregnant women must take the precaution of protecting against mosquito bites to avoid the risk of Zika virus infection. In addition, they should review their travel plans during their pregnancies.
