Summarize the following:
Although boils themselves are not contagious, the bacteria which causes them is. That's why it's very important to exercise caution and avoid sharing any towels, clothes or bedding used by a family member with boils. These items should also be thoroughly washed after used by the infected person. Good hygiene is probably the most important thing you can do to prevent boils As boils are usually caused by bacteria infecting the hair follicles, you should prevent the build up of bacteria on the surface of the skin by washing daily. Normal soap is fine. You can also use an abrasive brush or sponge, such as a loofah, to scrub the skin. This will break up any oil from becoming clogged around the hair follicles. Bacteria can easily enter the body through cuts and wounds on the skin. It can then travel down the hair follicle where it causes infection and the development of boils. To avoid this, make sure to clean all minor cuts and scrapes well with an antibacterial wash, apply a cream or ointment, and cover with a bandage until healed. Boils that form between the buttocks, also known as "pilonidal cysts," usually develop as a result of direct pressure caused by sitting down for long periods of time. They are common in truck drivers and people who have recently traveled on a long flight. If possible, try to relieve the pressure by taking frequent breaks to stretch your legs.

Summary:
Do not share towels, clothes or bedding with anyone who has a boil. Practice good hygiene. Clean any cuts or wounds immediately and thoroughly. Avoid sitting down for extended periods of time.
