Explosive diarrhea. It's a topic that no one wants to discuss, but with the recent surge in cyclosporiasis cases across the United States, it's hard to ignore. This gastrointestinal parasite has been causing quite a stir, and I'm here to shed some light on this unpleasant yet important issue.
Cyclosporiasis, pronounced similarly to "psoriasis," is a disease caused by the cyclospora parasite. This tiny parasite, invisible to the naked eye, resides in the feces of infected individuals. The real concern arises when these feces contaminate our food and water, leading to a cycle of infection. While cyclosporiasis isn't new, the rate of increase this year is indeed explosive, as Dr. Peter Chin-Hong from UCSF puts it.
The good news for Californians is that the state is currently experiencing fewer cases compared to last year. As of my last update, the California Department of Public Health reported a relatively low number of cases, with most linked to international travel. This is a relief, but it doesn't mean we can let our guard down.
One of the challenges with cyclosporiasis is its long incubation period. It can take up to two weeks for symptoms to appear after consuming contaminated food. This delay makes it incredibly difficult to trace the source of an outbreak. By the time symptoms manifest, the contaminated produce might already be off the shelves.
The symptoms of cyclosporiasis are quite distinctive. Watery diarrhea, loss of appetite, weight loss, bloating, and stomach cramps are some of the telltale signs. What's interesting is that some infected individuals may not show any symptoms at all. However, for those who do, the diarrhea can persist for several weeks, requiring antibiotic treatment to resolve.
So, what's causing this surge in cyclospora cases? The source of the outbreak in the Midwest remains unknown, and the CDC is still investigating. Health officials suspect that lettuce or salad greens might be the culprit in Michigan, but more evidence is needed. In the past, contaminated irrigation water has been a common cause of infection. The challenge lies in identifying the origin, especially when contaminated food can be distributed to both grocery stores and restaurants.
The CDC has faced criticism for federal funding cuts to state and local health departments, which have impacted their ability to track and control outbreaks like this. Dr. Chin-Hong highlights the importance of robust surveillance systems to easily control such situations. The reduction in funding has undoubtedly made it harder to interview patients and confirm cases.
If you're visiting an area with a cyclosporiasis outbreak, taking some precautions is advisable. Cooking produce to an internal temperature of at least 158 degrees can kill cyclospora. Washing produce thoroughly can also help reduce the risk of infection. Dr. Erika Noel recommends washing fruits and vegetables in vinegar, which can help remove the parasite. It's also important to wash cutting boards and countertops, as alcohol-based hand sanitizers are ineffective against cyclospora.
For those in California, the risk is relatively low, but it's still important to be vigilant. Remember, there are no known local outbreaks, and the CDC's surveillance map shows a low number of cases in the state. Dr. Chin-Hong suggests washing hands and produce carefully, especially green leafy vegetables. Sourcing produce from local farms can provide some peace of mind regarding the origin of your food.
If you're still concerned, avoiding higher-risk items like leafy greens, fresh herbs, and berries is an option. Instead, opt for lower-risk choices like bananas, oranges, avocados, melon, and mangoes, which have rinds or skin that can be removed. Always wash the outside of thick-skinned produce and your hands and utensils to prevent contamination.
In the Bay Area, diarrhea is more likely to be caused by other gastrointestinal diseases like norovirus and rotavirus. These viruses are commonly detected in wastewater year-round. However, if your diarrhea persists for an extended period, it might be worth considering cyclosporiasis.
One thing to note is that cyclosporiasis is not easily transmitted from person to person. The risk of infection is much higher from consuming contaminated food or fluid than from being near an infected individual. So, while it's important to be cautious, there's no need to panic.
In conclusion, cyclosporiasis is a serious gastrointestinal disease, but with proper precautions and awareness, we can reduce our risk. Stay informed, wash your hands and produce, and consider supporting local farms for a safer food supply. Remember, knowledge is power, and in this case, it can help keep us healthy.
