Malaria

Angkor is often visited at sunrise and sunset when mosquitoes are likely to bite, putting travelers at risk for mosquito-borne diseases such as malaria and dengue. Malaria chemoprophylaxis and mosquito avoidance are both recommended.
Atovaquone/proguanil or doxycycline should be taken to prevent malaria. Chloroquine and mefloquine are not recommended because P. falciparum may be resistant to these drugs in this area. Purchase malaria prophylaxis drugs in the United States before travel, because counterfeit malaria drugs have been found in Southeast Asia.
Avoid mosquito bites by using a recommended repellent, sleeping under a mosquito net if not in an air conditioned room, and wearing protective clothing. Mosquito bites can transmit not only malaria but other diseases such as dengue and Japanese encephalitis.(http://wwwnc.cdc.gov/travel/yellowbook/2010/chapter-3/angkor-wat-cambodia.aspx)
