Heading to HCMC, Nha Trang, and Hanoi for an exploratory trip. I'm considering spending a few years in those cities, maybe teaching English, but mainly just to enjoy my retirement.
I'm wondering about what measures expats take to guard their health. I understand about being careful with the water and food, but what other safeguards are generally taken in those three cites?
Do "cautious" expats live on malaria meds?
Do they apply DEET spray and lotion 24/7?
If one sticks to these cities, is a chance of mosquito-transferred disease fairly remote?
Any feedback would be helpful. Thanks to all.
