Human infestation happens when parasites live on or inside the body and cause symptoms you can feel or see. Common culprits include lice, scabies mites, intestinal worms, and some skin parasites. You usually notice itching, rash, visible insects or eggs, stomach pain, or unexplained weight changes. Quick identification speeds treatment and reduces spread to family or close contacts. This guide tells you what to look for, how to treat common infestations safely, and simple prevention steps.
How do you know what type you have? Look for where the symptoms occur and what you can see. Head lice cling to hair close to the scalp and leave tiny white eggs near hair roots. Body lice live in clothing seams and cause itching with small red bumps. Scabies causes intense night itching and thin burrow lines on the skin, especially between fingers, wrists, and waist. Intestinal worms may cause belly pain, diarrhea, and sometimes visible worms in stool.
When should you see a doctor? If itching is severe, if a rash spreads quickly, if you find eggs or worms, or if over-the-counter treatments fail, get medical help. Also see a provider if you have fever, signs of infection, or if an infant, elderly person, or someone with a weakened immune system is affected. Many infestations have prescription options that kill the parasite more reliably than home remedies.
Common treatments are topical creams for scabies, medicated shampoos for lice, and oral antiparasitic pills for worms. Follow dosing exactly and treat close contacts at the same time when recommended. For lice, wash bedding and clothing in hot water and dry on high heat; seal non-washable items in a bag for two weeks. For scabies, wash clothes and vacuum furniture and mattresses to remove mites.
Preventing reinfestation is mostly common sense. Don't share combs, hats, towels, or bedding during outbreaks. Check children after sleepovers and camps. Maintain good hand hygiene. For travel, use insect repellent when recommended and avoid areas with poor sanitation for food and water.
Household steps help. Treat affected people first, then clean linens and brushes. Disinfect combs and vacuum carpets. Inform close contacts so they can check themselves. Schools and group homes often require a treatment letter from a doctor before returning.
Medications can interact with other drugs and have side effects. Tell your provider about current medicines, allergies, pregnancy, or breastfeeding. If you notice worsening symptoms after starting treatment, contact your provider right away. For stubborn cases, follow-up testing or a specialist referral may be needed.
Quick action reduces misery and cuts spread. Spot the signs early, treat properly, and follow clean-up steps in the home. Need a specific article? Check our posts on lice, scabies, and intestinal worms for drug options and step-by-step guides.
