Young kids are more likely to have giardiasis than adults, but anyone can become infected. Most people who are infected with <em>Giardia</em> may have no signs of illness, even though the parasite is living in their intestines.</p> <p>Giardiasis often starts with watery diarrhea. Kids may also get belly cramps and gas. They might feel sick or throw up. Some kids may have a low-grade <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/fever.html/">fever</a>.</p> <p>Giardiasis is contagious. It spreads through feces (poop) that might get into food or water, or on hands.&nbsp;<span style="line-height: 16.8px;">Giardiasis</span>&nbsp;can spread to people from infected animals, even a family dog.&nbsp;</p> <p>Giardiasis is treated with prescription medicine to kill the parasites.</p> <h3>Keep in Mind</h3> <p><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hand-washing.html/">Washing hands</a> well and often can help stop&nbsp;<span style="line-height: 16.8px;">giardiasis</span>&nbsp;from spreading.
