how fast does tetanus set in

Tetanus usually doesn’t set in right away — symptoms most often appear 3 to 21 days after infection, with about 8 to 10 days on average. Most cases show up within 14 days.

Quick scoop

• Typical onset: 3–21 days after a wound gets infected.

What to watch for

Early signs can include:

• Jaw stiffness or trouble opening the mouth.

• Trouble swallowing.

When to get help

If you have a puncture wound, dirty wound, bite, or burn and you’re not up to date on tetanus shots , it’s smart to get medical advice quickly. Tetanus is a medical emergency if symptoms start, because it can worsen fast.
