What is Zika virus disease, non-congenital?

Zika virus was first identified in 1947 in a rhesus monkey in the Zika Forest of Uganda. The first human case was detected in Nigeria in 1952. For decades, it was considered a rare and mild illness, primarily causing small outbreaks in Africa and Asia, before larger epidemics emerged in the Americas starting in 2015.

Symptoms

Mild fever
Rash
Joint pain (arthralgia)
Red eyes (conjunctivitis)
Muscle pain
Headache
Symptoms are often mild and can last for several days to a week; many infected individuals are asymptomatic.

Transmission

Zika virus is primarily transmitted to humans through the bite of infected *Aedes* species mosquitoes, mainly *Aedes aegypti*. It can also spread through sexual contact with an infected person. Less common routes include blood transfusions and organ transplantation.

Contagious Period: Varies by disease

Prevention

Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus
Wear long-sleeved shirts and long pants
Stay in air-conditioned or screened rooms
Eliminate standing water around homes to reduce mosquito breeding sites
Use condoms to prevent sexual transmission of the virus (if you or your partner have traveled to a Zika-affected area)
Currently, there is no vaccine available to prevent Zika virus infection.
