    Cellulitis is often caused by an infection from bacteria. It can also be caused by a fungal infection.

    Other problems that can lead to cellulitis include:

    • insect bites
    • a skin wound (especially on the face)
    • dental surgery or other surgery of the head and neck
    • sinus infection
    • asthma

    An infection can start in the sinuses, then spread to the orbit or eyelid. Because sinus infections are more common in cold weather, cellulitis occurs more in the winter.

    It is important to clean any wounds carefully. You also need to follow your doctor or dentist’s instructions for caring for yourself after surgery.

    Cellulitis is serious because the infection spreads quickly. That is why it must be treated right away.

    If you think you or your child have cellulitis, call a doctor right away. If it is not treated immediately, cellulitis can cause vision loss or even spread throughout your body.

    It appears that as more people are getting flu vaccinations, fewer people are getting cellulitis—especially pre-septal cellulitis.
