Houston Faces Outbreak of Intestinal Parasite Causing Severe Diarrhea
Health officials in Houston are issuing warnings about a recent outbreak of an intestinal parasite that can lead to severe cases of diarrhea. The parasite, known as Cyclospora cayetanensis, has been causing gastrointestinal illness in both Fort Bend and Harris counties.
Symptoms of the infection include flu-like symptoms such as watery diarrhea, bloating, fever, stomach cramps, and muscle aches. Cyclospora is typically found in feces and feces-contaminated foods and waters, often spreading through the consumption of unwashed fruits and vegetables.
In recent weeks, doctors in the area have noticed a rise in cases of gastrointestinal illness caused by this microscopic parasite. Similar outbreaks have been reported in Georgia and Alabama, with more than 200 cases linked to the consumption of raw broccoli. In 2013, a widespread outbreak sickened hundreds of people after eating prepackaged salad mixes sold in the Midwest.
Fresh produce, including fresh cilantro, pre-packaged salad mix, raspberries, basil, snow peas, and mesclun lettuce, have been identified as potential sources of the recent Houston-area cases. Individuals on social media have been sharing their encounters with the distressing parasite.
Health officials are urging the public to exercise caution when handling and preparing such foods. It is recommended to thoroughly wash all fruits and vegetables under running water before eating, cutting, or cooking them. Additionally, it is important to thoroughly clean cooking boards, utensils, and other food preparation surfaces to prevent cross-contamination. Regular hand-washing for at least 20 seconds is also essential in preventing the spread of the parasite.
The Centers for Disease Control (CDC) highlights the challenge of tracking transmission as symptoms typically appear a week after exposure to the parasite. However, due to this long incubation period, person-to-person transmission is unlikely.
Cyclosporiasis symptoms can persist anywhere from a few days to a month and can sometimes disappear and reappear before fully resolving. Antibiotics can be prescribed by doctors to treat the illness. While the parasite does not typically cause lasting effects in healthy individuals, it poses a greater risk to the immunocompromised, infants, and the elderly. Health officials also note that diarrhea can lead to extreme dehydration, which is of particular concern during the current excessive heat wave in Houston.
Efforts are being made to raise awareness and prevent further transmission of the parasite in the community. It is crucial for individuals to adhere to recommended hygiene practices and take extra care when handling and consuming fresh produce.
