The night itch that spreads through a whole family is a tiny mite

It starts as an itch you can ignore. Then, night after night, it turns into something that keeps you awake — a clawing, all-over itch, worst once the lights are off. Small red bumps appear between your fingers, on the wrists, around the waist, the groin. Soon someone else at home is scratching too. You feel embarrassed, and a quiet question forms: is this dirty blood, an allergy, some fungal thing?

Here is the calm truth. This is almost certainly scabies — and scabies is a tiny mite, not a moral failing. A microscopic insect, smaller than a pinhead, has burrowed into the top layer of your skin and is laying eggs. The itch is your body reacting to it. It spreads by close skin contact and shared beds and clothes, which is exactly why it moves through families.

It is a mite, not 'gandaa khoon' — it has nothing to do with blood being dirty or being a bad person.
It is contagious, not a hygiene failure — clean, well-off people get it too.
The whole household must be treated together — even those not itching yet.
It is very curable — a doctor-prescribed scabicide cream or lotion clears it.

This is general information, not medical advice. A doctor or dermatologist should confirm it and prescribe the treatment.

Scabies is caused by a mite called Sarcoptes scabiei. The female burrows a thin tunnel into the outer layer of your skin and lays her eggs there. The eggs hatch, the young mites surface, mate, and the cycle repeats. There are usually only a small number of mites on one person — often just ten to fifteen — yet they cause misery far out of proportion to their size.

The itch itself is the clever, confusing part. It is not the bite that you feel; it is your immune system reacting to the mites, their eggs and their waste — an allergic-type response. This explains two things people find baffling. First, after you catch scabies, the itch can take roughly two to six weeks to start, because your body needs time to become sensitised. If you have had it before, it can flare in days. Second, even after correct treatment kills every mite, the itch can keep going for one to two weeks, because the allergic reaction in the skin settles slowly. Itching after treatment does not mean it failed.

It spreads through prolonged skin-to-skin contact — holding hands, sharing a bed, a child on a hip — and through bedding, towels and clothes used by an infested person. That is why it travels so easily within a household, a hostel or a crowded home, and why everyone close has to be treated at once.

Scabies will not clear on its own, and a random tube from the chemist often misses the mark. The plan is simple but must be done properly — by everyone at home on the same day.

See a doctor or dermatologist. They confirm it from the rash and burrows and prescribe a scabicide — usually a permethrin cream, sometimes an ivermectin tablet. The doctor decides; do not pick a drug yourself.

Apply the cream exactly as told. Usually over the whole body from the neck down (the scalp too in young children), left on for the stated hours, then washed off — often repeated after a week. Cover every fold.

Treat the whole household and close contacts the same day — partners, children, anyone sharing a bed, even if they have no itching yet. Untreated contacts simply re-infect everyone.

Wash bedding, towels and worn clothes in hot water, dry in strong sun or a hot dryer, then hot-iron. Heat kills the mites.

Seal what cannot be washed in a closed plastic bag for about a week; the mites die without skin to live on.

Expect some itch to linger for a week or two after treatment; ask your doctor what to use.

Go back sooner if the skin gets pus, crusts or fever (a secondary infection), or if thick crusts spread all over (crusted scabies) — these need urgent care. This is information, not medical advice; let a doctor guide the treatment.

Myth 1 — Scabies means 'dirty blood'.

There is no such thing as the itch coming from dirty blood. Scabies is one specific cause: a mite living in the skin. Your blood, your character and your past have nothing to do with it. Calling it 'gandaa khoon' only adds shame and delays treatment.

Myth 2 — Only poor or unhygienic people get scabies.

False. The mite spreads by close contact, not by dirt. Doctors, schoolchildren, hostel students and well-off families all get it. Bathing more often does not prevent it, because the mite lives under the skin's surface where soap cannot reach.

Myth 3 — A fungal or antifungal cream will fix it.

It will not. Scabies is a mite, not a fungus, so an antifungal cream does nothing to the mite. Only a proper scabicide, prescribed by a doctor, kills it. Guessing at the chemist usually wastes weeks.

Myth 4 — If I am not itching, I do not need treatment.

Dangerously wrong. You can be carrying mites for weeks before any itch begins. An untreated, itch-free family member keeps re-infecting everyone — which is why all close contacts are treated together, itch or no itch.

Myth 5 — It came back, so the medicine does not work.

Usually it is re-infection from an untreated contact, an unwashed bed, or cream missed on some folds — not a failed drug. Treating everyone and the linen together at once is what finally breaks the cycle.

Scabies is common — health bodies estimate it affects hundreds of millions of people worldwide at any time, and it is especially frequent in warm, crowded settings, including many parts of India. You are far from alone, and that is reassuring, not shameful.

How a doctor diagnoses it

Mostly by looking. A doctor or dermatologist usually diagnoses scabies clinically — by the pattern of the rash and the typical burrows between fingers, on wrists, waist and groin, plus a history of night itch and family spread.
Sometimes a closer look. Dermoscopy (a magnifying skin scope) or a gentle skin scraping examined under a microscope can confirm the mite when the picture is unclear.
No blood test diagnoses it — so anyone telling you it shows up as 'dirty blood' on a report is simply wrong.

What it costs in India (rough, varies a lot)

A doctor or dermatologist visitoften around ₹300–800 in clinics, more in private hospitals.
The prescribed scabicide cream or lotioncommonly in the ₹50–300 range per tube/bottle, depending on type and brand.
Government and many local clinics treat it at very low or no cost.

The most cost-effective step is not self-medicating for weeks; it is one proper visit so the right scabicide is prescribed and the whole household is treated together the first time.

Step back, and scabies is a small problem wearing a big disguise. A pinhead mite causes weeks of lost sleep, scratched-raw skin and a strange, lonely embarrassment — all of it fixable in a fortnight if you know what it is. The deeper lesson here is that the shame does more damage than the mite. When people hide the itch because they fear being called dirty, they delay the one visit that would end it, and they keep infecting the people they love.

What makes this story hopeful is how solidly it is in your hands. The mite cannot survive long away from human skin; treat every person and every bedsheet together, once, properly, and the cycle breaks. The reason scabies keeps coming back in homes and hostels is almost never that the medicine is weak — it is that one untreated, itch-free person was left out, or the linen was missed. Understanding that single fact is what turns a recurring nightmare into a one-time fix.

The broader point is this: a contagious condition spreads fastest in silence. The kindest, smartest thing you can do is the opposite of hiding — tell your household plainly, get everyone to the doctor on the same day, and treat it like the ordinary, curable infection it is. Scabies is common, it is no one's fault, and it ends the moment a family decides to face it together instead of scratching alone.
