Dengue in China (Guangdong Province)Updated February 20, 2015
Updated: February 18, 2015
What is the current situation?
The World Health Organization reported more than 47,300 dengue cases in China in 2014. This is mostly due to the dengue outbreak in Guangdong at the end of 2014. Travelers to China(http://wwwnc.cdc.gov/travel/destinations/traveler/none/china), particularly those going to Guangdong Province, should protect themselves against mosquito bites.
What can travelers do to prevent dengue?
No vaccine or medicine can prevent dengue. Travelers can protect themselves by preventing mosquito bites.

Prevent mosquito bites:
- Cover exposed skin by wearing long-sleeved shirts, long pants, and hats.
- Use an insect repellent as directed.
- Higher percentages of active ingredient provide longer protection. Use products with the following active ingredients:
- DEET (products containing DEET include Off!, Cutter, Sawyer, and Ultrathon)
- Picaridin (also known as KBR 3023, Bayrepel, and icaridin; products containing picaridin include Cutter Advanced, Skin So Soft Bug Guard Plus, and Autan [outside the United States])
- Oil of lemon eucalyptus (OLE) or PMD (products containing OLE include Repel and Off! Botanicals)
- IR3535 (products containing IR3535 include Skin So Soft Bug Guard Plus Expedition and SkinSmart)
- Always follow product directions and reapply as directed:
- If you are also using sunscreen, apply sunscreen first and insect repellent second.
- Follow package directions when applying repellent on children. Avoid applying repellent to their hands, eyes, and mouth.
- Treated clothing remains protective after multiple washings. See the product information to find out how long the protection will last.
- If treating items yourself, follow the product instructions carefully.
- Do not use permethrin directly on skin.
- Use permethrin-treated clothing and gear (such as boots, pants, socks, and tents). You can buy pretreated clothing and gear or treat them yourself:
- Stay and sleep in screened or air conditioned rooms.
- Use a bed net if the area where you are sleeping is exposed to the outdoors.
If you feel sick and think you may have dengue:
- Talk to your doctor or nurse if you feel seriously ill, especially if you have a fever.
- Tell them about your travel.
