What does the Zika virus do?

The Zika virus is a mosquito-borne disease that can cause a range of symptoms, including fever, rash, joint pain, and red eyes. In severe cases, it can lead to birth defects, such as microcephaly, a condition in which a baby's head is abnormally small.

The virus is spread by the bites of infected mosquitoes, particularly the Aedes aegypti and Aedes albopictus species. These mosquitoes are found in many tropical and subtropical regions around the world, including parts of Africa, Asia, the Pacific Islands, and the Americas.

The virus is most commonly transmitted to humans through mosquito bites, but it can also be transmitted through contact with an infected person's blood or other bodily fluids. The virus can also be transmitted from a pregnant woman to her fetus during pregnancy.

Symptoms of Zika virus infection typically appear 3-14 days after being bitten by an infected mosquito. The symptoms are usually mild and last for several days, but they can be more severe in some cases.

In pregnant women, Zika virus infection can cause birth defects, such as microcephaly. This condition can lead to a range of developmental problems, including intellectual disability, seizures, and vision and hearing problems.

There is no specific treatment for Zika virus infection. Treatment is supportive and may include rest, pain relievers, and fluids.

The best way to prevent Zika virus infection is to avoid being bitten by mosquitoes. This can be done by using insect repellent, wearing long-sleeved shirts and pants, and staying in areas with air conditioning or window screens.
