Fifth disease and croup are making the rounds this season. We've all heard of croup, but what is fifth disease?

Fifth disease is also known as 'slap cheek disease.' It's a virus and, like croup, it seems to be the disease da jour this spring and summer.

The name 'slap cheek disease' pretty much sums up the symptom. It appears on one's face and looks like a face slap. It's spread with saliva, respiratory droplets or through the blood stream and is particular concern in children, pregnant women and people with immune problems.

Basically, the best way to avoid fifth disease is to just practice basic cleanliness with regular hand washing and, of course avoiding contact with anyone exhibiting symptoms.

If you have symptoms, consult a doctor right away.
