Sepsis: Recognizing the Warning Signs Early

Source: U.S. Centers for Disease Control and Prevention (CDC)2 min readUpdated July 2, 2026

Sepsis is the body's extreme response to an infection. It can develop from an infection anywhere in the body — lungs, urinary tract, skin, gut — and can rapidly become life-threatening. Recognizing the warning signs early saves lives.

Know the signs — TIME

The CDC uses the acronym T-I-M-E to remember sepsis warning signs:

  • T — Temperature higher or lower than normal
  • I — Infection: may have signs and symptoms of an infection
  • M — Mental decline: confused, sleepy, difficult to rouse
  • E — Extremely ill: severe pain, discomfort, shortness of breath

Other common signs:

  • Clammy or sweaty skin
  • Rapid heartbeat or breathing
  • Very low blood pressure
  • Discolored or mottled skin

Who is at highest risk

  • Adults 65 or older
  • Infants younger than 1
  • People with weakened immune systems
  • People with chronic conditions such as diabetes, lung disease, cancer, or kidney disease
  • People who have recently had surgery or a hospital stay
  • People with implanted medical devices such as catheters or lines

What to do

  • If you or a loved one is very sick with an infection and any warning sign of sepsis, seek medical care immediately
  • Say the words: "I am concerned about sepsis." Clinicians will recognize the phrase and act
  • Do not wait to see if it gets better on its own

Prevention

  • Get recommended vaccines (flu, COVID-19, pneumococcal, shingles)
  • Take care of chronic conditions
  • Treat infections promptly — do not stop antibiotics early
  • Clean wounds thoroughly and watch for signs of infection
  • Wash hands often

After sepsis

Many survivors experience post-sepsis syndrome — fatigue, difficulty concentrating, sleep problems, or emotional changes — for weeks to months. Recovery is real, and rehabilitation helps.

Key takeaways

  • Sepsis is a medical emergency
  • Learn the T-I-M-E warning signs
  • Say the word "sepsis" out loud if you suspect it
  • Vaccines and prompt treatment of infections prevent many cases
