If one had a problem one could discuss it with a pharmacien and he would sell you what you needed without going to a doctor. Prescriptions didn't seem to matter. The pharmaciens were very competent and seemed to know a lot more than some of the doctors.
Unfortunately my French doctor got sick and went back to France to be operated on. He then returned to Saigon but his condition deteriorated and he had to leave again. He died shortly after in France. It was a great shame. A very good doctor, he was one of those rare one's I was comfortable with. Vietnam was a country where a person needed a doctor he could trust.
TB was endemic in Vietnam. One day I decided everybody should be checked. We found that an old family retainer living with us had it and I had to ask him to leave. He wasn't my responsibility and I couldn't put up with that in the house with children around.
