Key takeaway (WSMV) - The Metro Nashville Public Health Department says there have been less than 10 confirmed cases of cyclosporiasis, a parasite-induced illness causing diarrhea and vomiting in Davidson County.
Why this matters in The Nashville
The presence of cyclosporiasis in Nashville, with fewer than 10 confirmed cases, may not constitute a local outbreak, but it still warrants attention from residents and health officials. As the CDC continues to investigate the cause of the outbreak, the potential link to contaminated lettuce is particularly relevant for Nashville, given the city's vibrant food scene and numerous restaurants serving salads and other produce-based dishes. Dr. William Schaffner's advice to thoroughly wash produce before consumption is a crucial precaution for locals to take, especially during the summer months when fresh produce is in high demand. The fact that cyclosporiasis is not transmissible from person to person provides some relief, but the illness's unpredictable incubation period and potential for severe symptoms make it essential for the Metro Nashville Public Health Department to remain vigilant in monitoring cases and providing guidance to the public.
