Frequent Infections

Frequent infections deserve a medical review when they are recurring, severe, slow to clear, or disrupting daily life.

The pattern may involve repeated colds, throat infections, chest infections, skin infections, urinary infections, or mouth problems. Some people recover between episodes but become unwell again soon afterwards; others notice that a familiar infection takes longer to settle. Keeping a brief record of the body area affected, symptoms, medicines used, and recovery can make the pattern clearer.

Seek urgent assessment for trouble breathing, confusion, a new widespread rash with fever, severe neck stiffness, fainting, blue or grey lips, or a rapidly worsening illness. A baby, older adult, pregnant person, or someone whose immune system is weakened should be assessed promptly when they appear significantly unwell. Contact a clinician soon for recurrent infections with unexplained weight loss, persistent fever, or night sweats.

Repeated exposure to viruses, poor sleep, stress, smoking, skin damage, or incomplete recovery can contribute. Clinicians also consider conditions that can alter immune responses or how the body handles infection. The conditions below are listed alphabetically, not as a ranking of what explains your symptoms.

A clinician will ask which infections occur, how long they last, whether they were confirmed by a test, and whether there is a family history or use of medicines that affect immunity. Examination may focus on the chest, throat, skin, lymph nodes, abdomen, and signs of dehydration or poor nutrition. Tests are selected from the pattern rather than ordered automatically.

Treatment addresses the current infection and any contributor found during assessment. This may include fluids and symptom relief, an antimicrobial medicine when a bacterial infection is confirmed or strongly suspected, or treatment for a long-term condition. Do not use leftover antibiotics or share medicines, as the right treatment depends on the infection and your health history. Follow-up can check that recovery is complete and that the pattern is improving.

Wash hands after using the toilet, before preparing food, and after caring for someone who is ill. Cover coughs and sneezes, clean and dress cuts, keep routine vaccinations up to date, and avoid smoking. Regular meals, adequate fluids, sleep, and management of ongoing conditions can support recovery. If infections keep returning in one place, such as the skin or urinary tract, ask about targeted prevention for that body area.

Tell the clinician about fever, cough, diarrhoea, pain when passing urine, mouth ulcers, skin boils, swollen glands, fatigue, thirst, or changes in appetite. Also mention recent travel, new medicines, close contact with people who are ill, and any infection that required hospital care.

Untreated or repeatedly treated infections can lead to missed work or school, dehydration, spread to nearby tissues, and medicine side effects. Identifying a contributor can help clinicians choose prevention and arrange ongoing monitoring where appropriate.
