Lyme disease

An infection with Borrelia bacteria, spread to people by the bite of an infected tick.

LYM dih-ZEEZ noun

What it means

Named after Lyme, the town in Connecticut where it was first studied. In the US it is spread by blacklegged (deer) ticks. Early on it often causes a spreading red rash, sometimes shaped like a bull's-eye, with flu-like illness; if untreated, it can spread to the joints, heart and nerves. It is treated with antibiotics such as doxycycline.

For the nurse

Teach tick prevention: insect repellent, long sleeves and pants in wooded areas, and checking the skin after being outdoors. Remove a tick with fine tweezers held close to the skin, pulling straight up with steady pressure.
