Is cellulitis contagious?
Cellulitis — a skin infection that causes pain, redness, and swelling — isn’t contagious; you can’t catch it from someone else. Cellulitis is caused when bacteria that normally live on your skin enter your body and infect deeper tissues. This can happen if you have an injury such as a cut or burn, or even a scrape or insect bite.
You may also have a greater risk of getting cellulitis if you:
- Have a chronic skin condition such as eczema or athlete’s foot
- Have diabetes or vascular disease
- Are overweight
- Take immune-suppressing medications such as corticosteroids
- Get a tattoo or piercing
- Use injectable drugs
