What is Zika Virus Disease?
Zika virus was first identified in 1947 in a rhesus monkey in the Zika Forest of Uganda, with human cases documented since 1952. It gained global attention with major outbreaks in the Americas in 2015-2016 due to its severe link to microcephaly and other neurological conditions.
Symptoms
- Fever (typically mild)
- Rash
- Joint pain
- Conjunctivitis (red eyes)
- Muscle pain
- Headache
- Many infected people show no symptoms or very mild ones.
Transmission
Zika Virus Disease primarily spreads through the bite of infected Aedes species mosquitoes, particularly Aedes aegypti. It can also be transmitted from a pregnant mother to her fetus, causing birth defects. Less commonly, it can spread through sexual contact and blood transfusions.
Contagious Period: Varies by disease
Prevention
- Prevent mosquito bites: Use EPA-registered insect repellent, wear long-sleeved shirts and long pants, and stay in screened or air-conditioned rooms.
- Eliminate mosquito breeding sites: Remove standing water from containers around your home.
- Prevent sexual transmission: Use condoms or abstain from sex if you or your partner have recently traveled to or live in a Zika-affected area.
- Pregnant women should avoid travel to areas with active Zika transmission.
- No vaccine is currently available.
