Several vaccinations are advised before traveling to Cambodia; consult your GP or travel clinic six to eight weeks before departure to ensure you have time to complete all the series of injections.
Malaria is also present, so you will need to bring anti-malarial medication. Be aware that the malaria strain here is resistant to some forms of medication, so be sure to bring the appropriate type. Wearing long sleeves and trousers is also advised, as well as insect repellent. This also protects against dengue fever. Remember, malaria can develop up to a year after exposure, so keep an eye on any symptoms.
Tap water is unsafe to drink - also be wary of ice in drinks and unpeeled fruit and vegetables.
Schistosomiasis – also known as bilharzia – is a disease which can be caught in freshwater. It is present in Cambodia, so avoid swimming or bathing in lakes and rivers. Symptoms may not occur until after you return home; be sure to visit your GP if you are unwell.
Take note of the emergency number: 119.
Local hospitals are not of a very high standard, even in Phnom Penh; private hospitals are better equipped but may be costly. Ensure that your travel insurance covers medical evacuation and repatriation in case of an emergency.
Pharmacies may also have limited supplies, so if you are likely to need any medication, be sure to bring it with you.
