Hopefully, based on your post, there should only be small isolated outbreaks. Perhaps one of those fever radar machines that countries were using at airports should be used at these detention centers. People who are walking out get scanned for fevers. If they have a fever, then they can’t go out in public just yet. Hate to sound like a dictator, but these clusters may progress in a few short years to larger and more often.
I see FB posts with memes that read “How does my unvaccinated child threaten your vaccinated child”. I scratch my head because those who are so against vaccinating their children don’t seem to understand that there are others besides children involved.
A fever monitor would be of limited value for containing measles, since the disease becomes contagious a day or two before symptoms appear.
I have many times explained in this forum exactly how an unvaccinated child is dangerous to other people. For example, a teen might have such a mild case of pertussis that he does not know he is sick. But if he goes to visit someone’s new baby, he can spread the disease to that baby. And it is life-threatening in babies.
Since I have made a continuous effort to educate people on this forum about vaccines, I have seen fewer posts by anti-vaxxers. Every time I respond to anti-vax nonsense, I warn those who post that I watch for that stuff, and I respond. I am passionate about preventing these diseases, and, in some cases, effecting complete eradication. We are on the verge of completely eradicating measles and polio worldwide. That is a great thing!
