just out of interest... am adding the sentence taken from our local equivalent to the CDC... the tropical medicine institute in Antwerp Belgium

the adivce they give for Siem Reap is as follows: "in Siem Riep itself: the risk is low or non-existent, but there is a malaria risk in the neighbourhood of the city, and also limited risk in the region of Angkor Wat, when staying in this area, malaria tablets are necessary. People visiting these temples during the day and who return to their luxury hotel at night do not need to take malaria tablets. They need to carry a mosquito repellent to apply to their skin in case they are unable to get back before evening (due to e.g. illness, car failure, etc)"

still think i'll take some malarone along just in case (incidentally would not recommend taking Lariam to anyone... took it years ago in Senegal and never again... too many sideeffects)

Thanks, brusselschap for another source on this. As most people who go to the temples spend time at the temples at sunrise and sunset, they are at the temples when malarial mosquitos are most active.

agreed

Don't forget about the dengue which is as big a problem as malaria. You are at the temples all day when the dengue bugs are out. You need the DEET regardless; it's your only protection against dengue

I've been on Malarone twice...two trips, back-to-back years to Ghana. Personally, I refuse to take Larium...I've heard too many horror stories... along with one from a young woman I met...some years ago... while waiting in the Bangkok airport for a flight. She has permanent liver damage from taking Larium. And yes, of course, one can have reactions to anything, but there's just been too much negative stuff that I've heard about Larium over many years.
If anyone has Kaiser Permanente medical insurance(California) and I've seen it in Hawaii, well Kaiser has an excellent medical travel department.I've used both the one in San Diego...before we got our own L.A. one...and our L.A. one.
You just tell them the countries you're going to visit and they send out a packet of info on what you need to take and should take. I got all shots and Malarone there and the Malarone cost me, from what I can remember, between $10-$20...for a 3-week supply. The shots were free. I didn't even need an appointment...it was just walk-in. They had the shots ready at the sight I had chosen. Happy Travels!

I would also be very careful about taking larium. I know of two cases who had severe psychotic episodes that landed them in the hospital for weeks and others who have had life threatening side effects.

Gloria,
Am I the only one who thinks Larium has been too accessible in LA?
