Health authorities in the United States are warning of a rise in infections caused by Cryptosporidium, a microscopic parasite that can trigger severe diarrhea, stomach cramps, nausea, vomiting, dehydration, and fever. The parasite spreads through contaminated water, food, or contact with infected people and animals.
Public health experts say outbreaks are often linked to swimming pools, water parks, lakes, and untreated drinking water, especially during the summer months. Young children, older adults, and people with weakened immune systems are considered most at risk of serious illness.
Officials recommend frequent handwashing, drinking safe and treated water, thoroughly washing fruits and vegetables, and avoiding swimming if experiencing diarrhea to reduce the spread of infection. Most healthy people recover within a few weeks, but some cases may require medical attention to prevent dehydration.
Health agencies continue to monitor reported cases and encourage the public to seek medical advice if symptoms become severe or persist for several days. Early awareness and good hygiene remain the best defenses against infection.
