One of the reasons humans kept improving on civilization is it made us healthier. We enjoyed not enduring scourges like cholera and typhoid.
We stopped throwing our excrement on the streets and started filtering water and taking baths more often.
Sometimes we get complacent. We forget about basic sanitation. Or we let infrastructure rot, like in Flint, Mich.
Biology has a way of waking us up when that happens.
It certainly woke San Diego up.
We have always had homeless neighbors. But something happened about seven years ago. They pitched tents – set up encampments. They formed a disjointed neighborhood of their own, transcendent of our official neighborhood boundaries.
We Stand Up for You. Will You Stand Up for Us?
Giffin the homeless did not cause the Hep A outbreak, the stupid cutting off of a population from basic sanitary facilities did. By your logic Juarez would have to remove all the poor from the city to solve it's Hep A problem. Which is completely stupid because in reality Juarez doesn't have a functioning modern sewer/water system. Just look at the "other half of metropolitan Juarez", El Paso which does have a functioning modern sewer/water system. Public bathrooms in Juarez are a minefield of Hep A infections. BTW, I am in no way pointing any blame at TJ when I say this. TJ actually has a substantially better sanity infrastructure than Juarez or Nogales. TJ's sanitary system may have many issues, but it clearly works well enough to keep Hep A at bay.
Compared to the rest of the world, the sewer and water systems of the good ole USA are a modern miracle of civilization. Most of the worlds population lives in the 3rd world and every single one of them are keenly aware of all the prevalent infectious diseases that we in the USA are completely unaware of because "our plumbing works."
Personally I'm not the slightest bit worried about the hep A outbreak, I've been vaccinated more than ten years ago, with boosters only three years ago. I did this because back then my travels and business found me spending time in the third world.
A problem with dealing with this situation is in the term Homelessness.
This population is made up of mentally ill, addicts, alcoholics, vagabonds, people down on their luck and all the sub groups that makeup the mix we call "homeless"
Until there is the political will to deal with this problem it cannot be solved with one size fits all bandaids. The problem needs a triage and the first order of business should be removing the mentally ill, addicts and alcoholics from the equation. That begins by repealing the Lanterman-Petris-Short Act.
Governor Ronald Reagan blew it by signing it into law back in 1967. It is now evident that it is a failed policy that blocks any meaningful efforts to solve this problem.
