Unlike cryptosporidiosis, which mostly hits people with weakened immune systems, giardiasis can affect anyone, even healthy adults and kids, causing long-lasting diarrhea. Luckily, advanced water treatment, like reverse osmosis, offers real solutions for these water quality issues. AMPAC USA builds commercial and industrial systems specifically for these water treatment needs, and they come with certified, documented performance.<\/p>\n<p><span style=\"font-weight: Reses, H.

But what actually causes people to get giardiasis when there isn't an outbreak? We don't really know much about those risk factors. So, the Centers for Disease Control and Prevention teamed up with public health departments in Colorado and Minnesota to study risk factors for giardiasis that wasn't part of an outbreak in the USA. They looked at 199 patients with confirmed Giardia infection in Colorado and Minnesota, and compared them to 381 control subjects, matched by age and location. What did they find? International travel was a huge risk (aOR = 13.9; 95% CI 4.9-39.8), as was drinking water from a river, lake, stream, or spring (aOR = 6.5; 95% CI 2.0-20.6), or swimming in natural water (aOR = 3.3; 95% CI 1.5-7.0). Other risks included male-male sexual behavior (aOR = 45.7; 95% CI 5.8-362.0), being around children in diapers (aOR = 1.6; 95% CI 1.01-2.6), taking antibiotics (aOR = 2.5; 95% CI 1.2-5.0), and having a chronic stomach condition (aOR = 1.8; 95% CI 1.1-3.0). Interestingly, eating raw produce actually seemed to lower the risk of infection (aOR = 0.2; 95% CI 0.1-0.7). These results show that lots of different things can lead to giardiasis, even when it's not an outbreak. It's especially important to remember the risks that don't involve international travel, like person-to-person spread. To prevent infection, we should focus on reducing risks from handling diapers, sexual contact, swimming in untreated water, and drinking untreated water.<\/span><\/p>\n<p>https:\/\/www.cambridge.org\/core\/journals\/epidemiology-and-infection\/article\/risk-factors-for-sporadic-giardia-infection-in-the-usa-a-casecontrol-study-in-colorado-and-minnesota\/63B6FA03D86700897DFEA5473695A217<\/p>\n<p>The
