I am disputing your statement that the "Pool" was the source of your wife's illness,and the "Food" the source of the "others" illness,and you not getting ill at all because you spent less time in the pool!
If you came to the DR from another country for the week,you were exposed to many "Microbes" in the airports,and on the plane.That,combined with the drying effects of low humidity on your mucous membranes,and .....!
Whenever people gather in large groups,especially when from different parts of the Globe,many are bound to become ill with upper respiratory ang gastro-intestinal "Bugs"!
It always amazes me that when people get sick,they can always pinpoint the time,place,and source of that illness!
Hope you are all fully recovered by now!
Washing your hands many times a day,and using hand "sanitizers" can reduce these illnesses by many times.
CCCCCCCCCCCCCCCCCCC
PS,the DR is not "Developing",and much less "Industrial"!!!
