The tiny bug that creates big trouble
It’s the email that can create a collective groan among parents and guardians: the one informing parents that there’s a reported case of head lice in the classroom.
Head lice (Pediculus humanus capitis) are tiny, sesame seed-sized insects that feed on human blood. They typically live on the scalp, but can also be found on eyebrows and eyelashes. According to the Center for Disease Control and Prevention (CDC), while anyone can get head lice, but it’s most common in children ages 3 to 11.
“Children are more prone to head lice because they play and learn closely together, often sharing hats, helmets or combs,” explains Sean Sperl, nurse practitioner and manager of UH on the Go walk-in clinics. “It’s important to know that head lice are not a sign of poor hygiene – anyone can get them.”
Not surprisingly, the most common symptom of head lice is an itchy scalp, which is actually an allergic reaction to the bites. However, it may take up to a month after infestation for itching to begin. Adult lice will lay eggs (called nits) close the scalp, and these tiny, pinhead-sized eggs can be hard to spot.
“Removing lice and nits takes time and patience,” says Sperl. “Using a fine-tooth comb and working in small sections is key.” The providers at UH on the Go can help you choose the right over-the-counter and prescription medication options to ensure all lice and nits are eliminated.
The good news? Head lice can’t survive for more than two days without a human host. Washing bedding in hot water, sanitizing combs and vacuuming floors can help prevent re-infestation.
