Up to date and accurate information about all aspects of malaria, including risks and prevention, is readily available to you from travel health clinics, travel healthiness and via the web. Because it is a complex and rapidly changing issue, we do not want to recommend whether or not to take malaria medication.
Northern Palawan is generally a low risk area. Occasionally it comes in small outbreaks and consequentially the local health office will have a warning, we will be advised and pass on the warning to our travelers. It is not that very common for an outbreak during our season November to end of May. Be more cautious on Dengue fever which is more common and can be contracted anywhere in southeast Asia, especially in town and cities. There are no medicine to prevent catching Dengue so be always cautious. Dengue and Malaria normally appears mid monsoon season which is July-September.
It is advised to minimize the risk of Malaria and Dengue through bit avoidance. Bring lots of mosquito repellent and long sleeve clothing, it also advisable that when with children. in town it is better to get Air-conditioned rooms because mosquitoes are most active early in the morning/ late afternoon. Town and larger population have more disease carrying mosquitoes than those of small islands and villages.
Our sleeping in the islands are set up near the beach where we get a breeze thus reduce mosquitoes, we always have nets setup for sleeping. Traveling in South Palawan needs extra precaution any time of the year. Sand-flies are very common in the beaches- villages and Tao base camps in the islands. Some people react badly on sand-fly bites, long sleeves during sunset is advised for those special folks who attract mosquitoes and sand-flies.
The best ointment or repellent for mosquitoes and sand-flies in our expedition is Kwan Loong oil, a Singaporean mentholated oil. It is tried and tested by Tao for years. You have to re-apply every 30min but it is effective and much safer than any DEET products. If you can get it before coming to Palawan from Asian pharmacies or you can get it in our office in El Nido and Coron.
