 Navy Medicine released Zika virus infection guidance to Navy and Marine Corps personnel. U.S. Navy Surgeon General Vice Admiral Forrest Fason tells us how to stay safe. The Zika virus is spread by mosquito bites in some countries of the Western Hemisphere. There is currently no vaccine or treatment. The symptoms include fever, red eyes, muscle pain, joint pain, rash, and headache, and can last from three to seven days. Prevention is the best way to avoid infection. Avoid unnecessary travel to affected countries. When you're outside, cover exposed areas with long-sleeve clothes and pants, and use insect repellent frequently. Nothing is more important to us than your health and safety and that of your family. If you have symptoms or questions about the Zika virus, visit your Navy Medicine health care provider or view NavAdmin 032-16.
