Recurrent infections are episodes of infection that occur repeatedly over time. This page summarizes common contributing factors, which medical specialties may be involved, typical evaluation approaches and general prevention measures. For care tailored to an individual situation, contact a healthcare professional.
Recurrent infections can arise from one underlying problem or a combination of factors. Common contributors include weakened or altered immune function, chronic conditions such as diabetes, anatomical or functional changes in the affected area, repeated minor trauma or ongoing environmental exposure. Workplace risks, smoking, poor glycemic control and some medical treatments can also increase susceptibility.
Begin with a primary care clinician for initial assessment. Depending on the pattern and location of infections, referrals may include infectious diseases, clinical immunology/allergy, dermatology, urology or gynecology. Complex or systemic presentations often benefit from a multidisciplinary approach to identify underlying causes.
Evaluation starts with a detailed history and physical exam focused on frequency, affected sites and accompanying symptoms. Clinicians may order blood tests (CBC, inflammatory markers), microbiological cultures of affected sites, imaging when structural issues are suspected, and immunological investigations when an immune problem is a concern. The exact tests depend on clinical findings.
Basic steps can reduce infection risk: regular hand hygiene, proper wound care, keeping chronic conditions controlled, maintaining up-to-date vaccinations, balanced nutrition and adequate sleep. Workplace precautions and appropriate cleaning of frequently touched surfaces may also help. Specific preventive measures should be discussed with a clinician.
Seek urgent medical attention if symptoms include very high fever, severe or rapidly worsening pain, shortness of breath, sudden confusion or widespread rapidly spreading redness and swelling. These situations may require emergency care. For non-urgent concerns, arrange evaluation with your primary care provider or a referred specialist.
