What are boils, abscesses, and cellulitis?

These are bacterial infections of the skin that usually begin from a scratch or bug bite and may progress to a red nodule that fills with pus. Boils are superficial infections with a thin layer of skin over fluid. Abscesses are generally larger and deeper with redness and painful swelling over an area filled with pus. Cellulitis is an infection within the skin and the area just beneath it; the skin is red and tender to touch. The area of cellulitis can spread quickly.

What are the signs or symptoms?

Abscesses and boils tend to be softer in the middle over the fluid or pus than at the edges. They may drain when the skin over the infected area opens and lets the fluid or pus out. Signs of cellulitis include areas of redness and skin tenderness. The skin over these infections is usually warmer than the surrounding normal areas of skin because of the body's reaction to the infection.

What are the incubation and contagious periods?

The incubation period is unknown. Common skin bacteria (staphylococcus and streptococcus) are usually the cause of boils/abscesses/cellulitis. These bacteria are present on the skin of most children and usually do not cause a problem. However, skin bacteria may cause infection when there is a break in the skin or the bacterial infection overpowers normal defenses against infection. Having a methicillin- resistant Staphylococcus aureus (MRSA) skin infection is no more serious than other staphylococcal skin infections (see also Staphylococcus aureus [Methicillin-Resistant (MRSA) and Methicillin-Sensitive (MSSA)] Quick Reference Sheet). Regardless of the bacteria, these skin infections are contagious when the infected area is open and draining. People who carry the bacteria in their noses and throats and on their skin may pass the bacteria on to others. However, for a skin infection to occur, the bacteria must get through a break in the skin.

How is it spread?

Person-to-person contact with pus and skin bacteria and, to a lesser extent, contaminated environmental surfaces and objects

How do you control it?

What are the roles of the teacher/caregiver and the family?

Exclude from group setting?

No, unless

Readmit to group setting?

Yes, when all the following criteria are met:

When exclusion criteria are resolved, the child is able to participate, and staff members determine they can care for the child without compromising their ability to care for the health and safety of the other children in the group
