Going to Cambodia in two weeks
 

I already have the typical Typhoid/Hep/Yellow Fever and such. Our local fixer is saying no need for Malaria tabs, she doesn't know anyone who gets it, just cover up with DEET. We'll be there for 5 days.

Anything else I should be considering?

..if you are not in the city...
 

if you are tavelling outside the main city - you are really advised to take
prophylactics

have a look and a read here.
Cambodia Malaria Map - Fit For Travel

its states:
Malaria precautions for Cambodia

• Malaria risk is present throughout the country. Risk is minimal in the capital city Phnom Penh, Siem Reap, the famous temple of Angkor Wat, the nearby Mekong river delta and in the rice growing areas around the large inland lake of Tonle Sap.
• Malaria precautions are essential.
• Doxycycline is usually recommended for western provinces. Mefloquine or doxycycline can be used for other risk areas. Atovaquone/proguanil is an alternative to mefloquine or doxycycline.
• If you have been travelling in a malarious area and develop a fever seek medical attention promptly. Remember malaria can develop even up to one year after exposure.
• If travelling to high risk malarious areas, remote from medical facilities, carrying emergency malaria standby treatment may be considered.

DO NOT take the risk if you are going outside the areas stated in the first bullet point....it only takes ONE bite even though you may only be outside the ' safe' area for a few mins or more..... You do not want to experience this sometimes fatal infection.

the local fixer may not know of anyone - but that doesnt mean there isnt anyone! why take the risk - its a small and cheap tablet.

If you use any of the swimming pools offered by the hotels be carefull. Our little Auberge in Siem Reap took us to one they knew of, didn't seem bad. but my friend got Typhoid (yes he had jabs but they are only about 90% effective) and I had to get him to the US embassy in PP (there isn't or wasn't a UK one). It was close and it ended his trip.

he was swimming lengths underwater but not actively swallowing it!

just be carefull.
