Hard-to-kill poop parasites that lurk in swimming pools on the rise, CDC warns
Outbreaks of the gastrointestinal parasite cryptosporidium have been spurting upward since 2009, with the number of outbreaks gushing up an average of 13% each year, according to researchers at the Centers for Disease Control and Prevention. The germ spreads via the fecal-oral route and causes explosive, watery diarrhea that can last for up to three weeks. Most victims pick up the infection from recreational waters, such as swimming pools and water parks.
The main trouble is that crypto is extremely tolerant of chlorine and can happily stay afloat in well-treated pools for more than seven days. Thus, sick swimmers are the main source of infection—often young children who have yet to master toilet skills and also have more of a tendency to gulp pool water. An infected person can shed 100 million parasite eggs in one bout of diarrhea. Knocking back just 10 or fewer eggs in contaminated pool water can lead to an infection.
A 2013 study released by the CDC found that 58% of tested pools were positive for bacteria typically present in fecal matter.
[...] In all, the CDC recorded 444 outbreaks, involving 7,465 cases, 287 hospitalizations, and one death from the parasite. The number of cases per outbreak ranged from two to 638. However, the CDC notes that the figures likely underestimate the number of outbreaks and cases given that not every state reliably reports outbreaks and many people don't report their illnesses.

Let’s take the next step suggested by your logic and prohibit US citizens abroad from re-entering the country if you think our medical screening isn’t good enough.

My premise was that the current medical screening for people trying to come to the US is pretty thorough. You seem to assume some other premise that is opposite of what I wrote in that post.

Yes, that was your (or some AC’s) premise which followed another AC comment earlier in the thread:
“Could it be that people are coming into the US without getting a proper health screening?“
This suggests that the premise might be false. That was some other AC, right?
Why did I bother?

A. So could it be?
B . Or no, that is impossible?
A or B, simple question.
