Chikungunya Virus Epidemic Spreading
“No vaccine exists to prevent chikungunya virus infection or disease. You can prevent chikungunya virus infection by avoiding mosquito bites (see below). The mosquitoes that spread the chikungunya virus bite mostly during the daytime.
“Protect Yourself from Mosquito Bites “
“Use air conditioning or window/door screens to keep mosquitoes outside. If you are not able to protect yourself from mosquitoes inside your home or hotel, sleep under a mosquito bed net.”
“Help reduce the number of mosquitoes outside your home or hotel room by emptying standing water from containers such as flowerpots or buckets.”
“When weather permits, wear long-sleeved shirts and long pants.”
“Use insect repellents
• Repellents containing DEET, picaridin, IR3535, and oil of lemon eucalyptus and para-menthane-diol products provide long lasting protection.
• If you use both sunscreen and insect repellent, apply the sunscreen first and then the repellent.
• Do not spray repellent on the skin under your clothing.
• Always follow the label instructions when using insect repellent or sunscreen.
