I would like to know if skype is available at the internet cafes and if u can buy misquito repellent or deet products in yangon.is it cheaper to buy in myanmar.would also like to know how to protect yourself from dengue fever.
yes you can buy repellant in Yangon, I just do not remember the price. I even rememebr some market stalls having repellents, but I am not sure whether those could be diluted...
The only real protection against Dengue is to avoid moskito bites, i.e. repellents, nets, long trousers at dusk etc. There is no vaccination for Dengue and treatment is difficult.
One thought: If you go to a high risk Dengue and Malaria region, I would take malaria prophylaxis as a prophylaxis, not as a standby. This way you have at least an idea which fever you are getting and not force your metabolism to go through high level malaria treatment while you actually have dengue
All the above are my thoughts. In general you should talk to a physician...
have fun

Better to buy DEET in Canada where you can choose your strength and know it has not been diluted. Strongest I found in BK was 20%. Didn't look in Yangon. See CDC travelers health site (link in SEA FAQs). This from CDC Yellow Book (2008): "DEET formulations as high as 50% are recommended for both adults and children >2 months of age. The recommendations for DEET use in pregnant women do not differ from those for nonpregnant adults."

Re Eggert's comment: Easy to diagnose malaria, so unless you're deep in the bush, unlikely to be treated with shotgun approach. Again, see CDC - they know more than your doctor (unless she/he is infectious dz specialist).

There are couple of internet caffes in Yangon in Mandalay, that have Skype. In Mandalay I had to wait 5-10 minutes to log on and communication was possible only for a few seconds. In one of the Yangon places I could really talk - but with 20 seconds delay. Useless, give it up
The skype bug of Myanmar carries a particularly viralent strain of dengue fever. Recent research has indicated that the local practice of applying ground wood to the face as a cosmetic has allowed direct injection of the parasite through the skin via tiny splinters. The bug then grows and erupts through the skin in alarming colonies of maggots.
