Borneo typically as a whole is classified as a ‘high risk’ area for malaria. In reality, there will be areas in Borneo that are higher risk – like inner rainforests and rural areas – and areas in Borneo that are a lower risk which typically includes most of the places tourists visit in Sabah e.g. Kota Kinabalu, Kinabatangan Wildlife Sanctuary etc. We would always recommend you seek your Doctors advice on what medical precautions you should take when coming on holiday to Sabah, Borneo. It then comes down to the level of risk you want to take when coming on holiday regarding your health.
