Q:Chickenpox got its name from a similar skin condition seen in young chickens. True or False?

A:False. Chickenpox as an illness is not related to chickens. As chickenpox is weak, or far less deadly when compared to the more aggressive smallpox, the term "chicken" as used in "chickenpox" refers to "chickenhearted," meaning weak, timid, or bashful. The disease has been termed "chickenpox" since about the 16th century.

Q:Chickenpox takes about a month to run its course. True or False?

A:False. While it generally takes about 10-21 days for a person to develop chickenpox after being exposed, chickenpox generally takes about 10 additional days to run its course. The chickenpox rash will usually appear a day or two after the first symptoms start. Once the rash appears, each spot takes about a day or two to go through its stages, including blistering, bursting, drying out, crusting over, and scabbing. New chickenpox blisters appear, and this cycle is repeated for about five to seven days. A person is no longer contagious once the blisters have all crusted over.

Q:Children with chickenpox should be seen by a doctor. True or False?

A:False. For healthy children, it is not always necessary to see a doctor. If a child appears to be developing chickenpox, parents may wish to call the doctor to determine if the doctor wants to see the child. Most healthy kids require only home treatment to manage their symptoms, including rest, fever-reducing medicines, and anti-itch medications and oatmeal bath soaks.
