Late-onset sepsis: definition

The exact timing used for late-onset sepsis depends on age and the clinical setting. The key issue is not the label but a harmful response to infection that can affect circulation and organ function. Infection may begin in the lungs, urinary tract, skin, or another site; pneumonia, urinary tract infection, and cellulitis are examples of possible sources.

Babies may show poor feeding, temperature instability, unusual sleepiness, breathing changes, or colour change. Older children and adults may develop fever or chills, fast breathing, confusion, marked weakness, or a rapidly worsening sense of illness. No single symptom confirms or excludes sepsis.

Treat suspected sepsis as urgent. Contact emergency services or go to an emergency department when a person is deteriorating, especially if they are difficult to wake, breathing abnormally, cold or mottled, or passing very little urine. Do not wait for a home test or try to manage severe symptoms with fluids alone.

Clinicians may check vital signs, examine for an infection source, and arrange blood or other tests. Treatment depends on the findings and can include prompt antibiotics, fluids, oxygen, and close monitoring.

Seek emergency care for confusion, severe breathlessness, fainting, blue or mottled skin, a seizure, extreme drowsiness, or sudden deterioration. Fever, chills, feeling generally unwell, or generalised weakness with a suspected infection also warrants prompt medical advice, particularly in a newborn, older person, or someone with reduced immunity.

Ask where the infection may be located, which observations and tests are being used, what treatment is planned, and which changes should be reported immediately after going home.
