Mosquitoes are prevalent throughout the reserve and it is strongly recommended that visitors should take an anti-malarial prophylactic before, during and for four weeks after their visit, especially during the rainy season. Water for drinking should be boiled or chemically treated.
Malaria area - minimize mosquito bites by wearing light, long sleeved clothing and using effective insect repellents (containing Diethyltoluamide DEET) on exposed skin. Sleep under treated mosquito netting or ensure that the doors and windows of your accommodation are screened against mosquitoes.
Having a fan or air-conditioner on at night will further suppress mosquito activity. Currently, the three effective anti-malaria tablets are Mefloquine (Lariam or Mefliam), Doxycycline and Malarone (Malanil).
It is still possible to contract malaria while on malaria prophylaxis. Note that Lariam may present serious side-effects - please test before you depart.
