sepsis how do you get it

Sepsis happens when your body has an extreme, life‑threatening reaction to an infection, not from “catching sepsis” itself like a cold.

What sepsis is (in plain language)

Sepsis is your immune system going into overdrive while fighting an infection and, in the process, damaging your own organs. Instead of just attacking the germs, the body releases lots of inflammatory chemicals into the bloodstream, which can make blood vessels leaky, drop blood pressure, and reduce blood flow to vital organs. If this spirals further, it can lead to septic shock, organ failure, and death if not treated quickly.

Think of it like this: the fire alarm goes off for a small kitchen fire (a local infection), but the sprinkler system floods the whole house (sepsis).

How you “get” sepsis: where it usually starts

You get sepsis when an infection anywhere in the body triggers this overwhelming response. Common starting points include:

  • Lungs – pneumonia and other chest infections.
  • Urinary tract – bladder or kidney infections (UTIs, pyelonephritis).
  • Abdomen/digestive system – infections in the bowel, appendix, gallbladder, or after abdominal surgery.
  • Skin and soft tissue – infected cuts, cellulitis, wounds, burns, pressure sores, injection sites.
  • Bloodstream infections – from serious infections elsewhere, from IV lines, catheters, or other devices.
  • Brain and coverings of the brain – meningitis and similar infections.

Any infection that is not treated properly, or that gets worse despite treatment, has the potential to lead to sepsis.

What kinds of germs can trigger it?

  • Bacteria – the most common cause of sepsis worldwide.
  • Viruses – including influenza and COVID‑19.
  • Fungi – such as Candida infections, especially in people in hospital or with weak immune systems.
  • Parasites – for example, severe malaria.

Who is more at risk?

Anyone can get sepsis, including young, healthy people, but some groups are at higher risk if they get an infection:

  • Adults over 65.
  • Babies and very young children.
  • People with weakened immune systems (cancer treatment, HIV, long‑term steroids, certain medications).
  • People with chronic illnesses (diabetes, kidney disease, lung disease, liver disease).
  • People recently in hospital, especially in intensive care, or with surgery or invasive devices like IV lines, catheters, or breathing tubes.
  • Anyone with a severe wound, burn, or major injury.

Early warning signs you should never ignore

You can’t diagnose sepsis at home, but certain “red flag” signs with an infection mean you need urgent help.

Watch for (in an adult or older child):

  • Very fast breathing or trouble breathing.
  • Very fast heart rate.
  • New confusion, disorientation, or acting “not themselves.”
  • Mottled, bluish, or very pale skin, or a rash that doesn’t fade with pressure.
  • Not passing much urine (or none) in a day.
  • Feeling extremely unwell, like “the worst you’ve ever felt.”

In babies and young children, extra danger signs include being floppy or hard to wake, a very high or very low temperature, breathing very fast, not feeding, or a mottled/blue rash.

Many sepsis awareness campaigns recommend that if someone with an infection seems suddenly much sicker, you explicitly say to healthcare staff: “Could it be sepsis?”

How people often end up with sepsis (story‑style example)

Imagine someone gets pneumonia during winter. At first it feels like a bad chest infection, but they delay seeing a doctor. The infection spreads in the lungs, bacteria and their toxins enter the bloodstream, and the immune system reacts strongly. Over a day or two, they become very short of breath, confused, feverish, and their blood pressure drops. That is sepsis developing from a “simple” lung infection.

The same pattern can happen from a UTI that reaches the kidneys, an infected cut on a leg, or an abdominal infection after surgery.

Can you catch sepsis from someone?

You do not “catch” sepsis from another person the way you catch the flu.

  • You can catch the infection (for example, flu, COVID‑19, or some bacterial infections), but whether it turns into sepsis depends on your body’s response and your risk factors.

Everyday ways to reduce your risk

You can’t reduce the risk to zero, but you can lower the chances that an infection becomes severe enough to cause sepsis:

  • Treat infections early: Don’t ignore high fever, worsening pain, or feeling very unwell.
  • Follow antibiotic instructions exactly when they’re prescribed.
  • Keep wounds clean: Wash, cover, and watch for redness, swelling, pus, or spreading pain.
  • Stay up to date with vaccines (flu, COVID‑19, pneumonia, etc.) to prevent major infections.
  • Manage chronic conditions like diabetes as well as possible.
  • In hospital, remind staff about hand hygiene and raise concerns about drips, catheters, or wounds that look sore or inflamed.

If you’re worried right now

If you or someone with an infection suddenly:

  • Gets much more short of breath,
  • Becomes drowsy or confused,
  • Has mottled or blue skin, or
  • Just feels “something is really wrong,”

you should seek emergency medical care immediately and tell them you are concerned about sepsis.

When in doubt—even if you’re not sure it’s “bad enough”—it is safer to get checked and say the word sepsis out loud.
