Campylobacter Infection: Symptoms, Treatment & Recovery
Campylobacter is a leading bacterial cause of foodborne illness in the United States, responsible for an estimated 1.3 million infections annually according to CDC data. Infection typically results from consuming undercooked poultry or unpasteurized dairy products. Understanding symptoms, incubation periods, and treatment options helps you seek timely care and prevent complications.
Campylobacter Symptoms & Incubation Period
Symptoms typically appear 2–5 days after exposure, though the range extends to 10 days. Most infected individuals experience watery or bloody diarrhea, cramping abdominal pain, fever (often 101–102°F), and nausea. Some people remain asymptomatic carriers, spreading the pathogen to others. In immunocompromised individuals, infection can become severe and invasive, requiring hospitalization. Symptoms usually last 5–7 days but may persist longer in severe cases.
Treatment & When to Seek Medical Care
Most Campylobacter infections resolve without specific treatment through supportive care: hydration with oral rehydration solutions, rest, and avoiding antimotility drugs (which can worsen outcomes). The FDA recognizes that antibiotics—primarily azithromycin or fluoroquinolones—are reserved for severe cases or immunocompromised patients, as antibiotic resistance is increasing. Seek medical attention if you experience bloody stools, severe dehydration, high fever lasting over 3 days, or symptoms in very young children, elderly individuals, or those with weakened immune systems. A healthcare provider may recommend stool cultures to confirm diagnosis.
High-Risk Foods & Vulnerable Populations
Raw or undercooked poultry is the most common source; ground chicken and whole birds pose significant risk if internal temperatures don't reach 165°F. Unpasteurized milk and untreated water also harbor Campylobacter jejuni and C. coli. Cross-contamination during food preparation spreads bacteria from raw poultry to ready-to-eat foods. Infants, pregnant women, older adults, and immunocompromised individuals face elevated risk of severe infection. Recovery is typically complete within 2 weeks, though post-infection complications like Guillain-Barré syndrome occur rarely but warrant neurological monitoring.
