Zika Fever

A disease caused by Zika virus that's spread through mosquito bites.

In most cases, there are no symptoms. In a few cases, Zika can trigger paralysis (Guillain-Barré Syndrome). In pregnant women, it may cause subsequent birth defects.

When present, symptoms are mild and last less than a week. They include fever, rash, joint pain, and red eyes. There's no vaccine or specific treatment. Instead the focus is on relieving symptoms and includes rest, rehydration, and acetaminophen for fever and pain. Aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen should be avoided.
