How can I protect myself against illness while traveling?

You should monitor your level of health closely at all times while traveling.  It is important to protect yourself against sunburn by wearing the proper UVA/UVB protection and appropriate clothing.  You should also be sure to protect yourself against insect bites by wearing insect repellent that contains 30%-50% DEET or 15% picaridin.  Be sure to wear long pants and sleeves at night when you are in malaria-risk areas.  Ensure that you stay in a good quality hotel that is well screened and that has air conditioning.  In addition to this, wash your hands frequently, especially before you eat and avoid handling animals.  Finally, be sure to follow all local laws and customs to avoid any risk of injury or illness.
