Best to get shots before you go too, malaria at least.
That's OK if you only go for a short holiday, but if you live permanently in the country then you cannot take Malaria tablets all the time since the drug itself is somewhat dangerous to take on a long term basis.
So as a 'Brit' living in Burma, I have no vaccinations (apart from tetanus) and so far have been lucky not to catch malaria.
The biggest risk is Dengue fever, which is spread by daytime mosquitos. There is no vaccination and it can be fatal. So I run when I see a mosquito in the daytime.
Seriously, dengue is one of the major illnesses in Burma and other under-developed south-east Asian countries. It is a killer and is far more prevalent than malaria.
Here in Burma, the health system is extremely basic. God help me if I get seriously ill. A sobering statistic is that about 30% of newborn babies born in government hospitals die. (This is actually because many people are too poor to give birth in hospital and only attend the hospital if complications arise).
I live in a 'slumish' area of Yangon (Rangoon), with open sewers and I regularly see people defecating in the street
Thanks to my mother's terrible cooking, I developed a cast iron stomach as a child. I have avoided major food poisoning so far..
At my QTH, the QRN is not too bad. I have a PSK 20 mb rig and can hear stations from all corners of the globe. I'm located very near to the river, so that helps
