What signs does a person have if they have lice? - in detail
Lice infestation produces unmistakable symptoms that appear on the scalp and surrounding skin. The most common indication is persistent itching, caused by an allergic reaction to the insect’s saliva. Scratching often leads to small, red papules or bumps that may bleed slightly when broken.
Visible evidence includes live insects and their eggs. Adult lice are about the size of a sesame seed, gray‑brown, and move quickly through the hair. Eggs, or nits, cling firmly to hair shafts near the scalp and appear as tiny, oval, white or yellowish specks. Because nits are attached at an angle of roughly 30–45 degrees, they can be distinguished from stray dandruff.
Secondary irritation may develop when the skin is repeatedly scratched. Signs include crusted sores, scabs, and, in severe cases, bacterial infection that produces pus and increased redness. The scalp can feel tender to the touch, especially along the hairline, behind the ears, and at the nape of the neck.
Behavioral changes often accompany the physical symptoms. Affected individuals may experience difficulty concentrating, irritability, and disrupted sleep due to the constant sensation of movement on the scalp.
Typical diagnostic clues are:
- Intense, localized itching that worsens several hours after waking.
- Presence of live lice or nits attached close to the scalp.
- Small, inflamed bumps or scabs on the scalp skin.
- Evidence of secondary infection such as pus or excessive redness.
- Reports of sleep disturbance or heightened irritability.
Recognition of these signs enables prompt treatment and prevents further spread.
