Intense itching that gets worse at night. Small spots between the fingers, around the wrists and waist. And soon, other people in the house start scratching too. This is the classic story of scabies, a very common skin problem in Bangladesh — in homes, madrasas, hostels, garment factory dormitories and crowded areas.
Scabies is not a sign of being dirty. The NHS states clearly: anyone can get scabies, and it has nothing to do with poor hygiene. It is easy to treat when done correctly, but treatment often fails because only one person is treated, or the steps are not followed. This guide explains how to get it right.
What Is Scabies?
The WHO describes scabies as a parasitic infestation caused by tiny mites (Sarcoptes scabiei) that burrow into the skin and lay eggs, causing intense itching and a rash.
How common is it? The WHO estimates more than 200 million people worldwide have scabies at any one time. It is most common in hot, tropical countries and crowded areas, and 5% to 50% of children in resource-poor settings may be affected.
Scabies Symptoms
The NHS lists the main symptoms as:
- Intense itching, especially at night
- A raised rash or spots
The spots may look red on white skin; on brown skin they can be harder to see but you should be able to feel them. The rash may leave dark spots.
Where the rash appears
The NHS says the rash often affects:
- Between the fingers
- Around the wrists
- Under the arms
- Around the waist, groin and bottom
It usually spreads across the body apart from the head and neck. However, older people and young children may get a rash on the head, neck, palms and soles of the feet.
The WHO also describes itchy lines (burrows) and bumps on fingers, wrists, arms, legs and the belt area, and inflamed bumps on male genitals and female breasts.
When symptoms start
The WHO says symptoms usually begin 4–6 weeks after infestation in a first infection. The NHS notes it can take up to 8 weeks for the rash to appear. This is why people in the same house may have mites before they itch.
Crusted scabies
The NHS explains that people with a weakened immune system can get a rare, very contagious form called crusted scabies, with a crusted, flaky rash often on the elbows, knees, hands and feet. This needs a doctor.
Example
Shila, 30, lives with her husband, two children and mother-in-law in a small flat in Narayanganj. Her 7-year-old son started itching at night, mostly between his fingers. A week later, Shila and her daughter began itching too. Only the son was treated with a cream, and the itching kept returning in the family. The problem was solved only when all five were treated on the same day and the bedding was washed.
How Scabies Spreads
The NHS says scabies spreads through close skin contact, including sexual contact. You cannot get scabies from pets.
People who live or work closely together — in nurseries, university halls, nursing homes — are more at risk. In Bangladesh, this includes hostels, madrasas, dormitories, and families sharing beds.
Sharing bedding, clothes and towels with someone who has scabies also adds to the risk.
Scabies Treatment
Medicines
The WHO says scabies is treated using creams or oral medicines. The NHS describes a cream or lotion applied over the whole body. Commonly used treatments include permethrin cream; a doctor may prescribe other options, including tablets, in some cases.
How to apply (NHS guidance)
- Apply the cream or lotion over your whole body, including your scalp and face (but not around the eyes)
- Follow the leaflet for how long to leave it on before washing off
- Repeat the treatment 7 days later
- Tell the pharmacist or doctor if you are pregnant or breastfeeding
Treat everyone at the same time
This is the most important rule. The NHS says:
- Everyone in your home needs to be treated at the same time, even if they do not have symptoms
- Anyone you've had sexual contact with in the past 8 weeks should also be treated
Children under 2
The NHS says do not use pharmacy treatments on children under 2 years old — they need to see a doctor.
Stopping Scabies From Spreading During Treatment
The NHS advises:
Do
- Wash all bedding and clothing in the house at 60°C or higher, and if possible in a hot dryer, on the first day of treatment
- Put clothing that cannot be washed in a sealed bag for at least 3 days until the mites die
Don't
- Do not have sex or close physical contact until the full course is finished
- Do not share bedding, clothing or towels with someone with scabies
Practical tips for Bangladeshi homes
- If you don't have a washing machine, wash bedding and clothes in very hot water where safe, and dry them in strong sunlight
- Bag pillows, quilts (kantha/lep) and soft toys for at least 3 days if they can't be washed
- Do all this on the same day as the first treatment for the whole family
How Long Does Scabies Take to Go Away?
The NHS says:
- Adults and children 5 and older can return to work or school as soon as they've started treatment, but should avoid close contact for the first 24 hours
- Children under 5 can return to nursery 24 hours after the first treatment
- The treatment kills mites quickly, but itching can carry on for a few weeks
Ongoing itching right after treatment does not always mean treatment failed.
When to See a Doctor
The NHS advises seeing a doctor if:
- Your child is under 2 and has symptoms, or someone in the household has scabies
- You think your skin may be infected, or you have another skin condition like eczema
- You have a crusted, flaky rash on elbows, knees, hands or feet
- You are still itching 2 to 4 weeks after finishing treatment
Complications
The WHO warns scabies can lead to skin sores that become infected, and serious complications such as septicaemia (bloodstream infection), heart disease and kidney problems. Get medical help quickly if sores become painful, swollen, hot, or full of pus, or if there is fever.

Frequently Asked Questions
What is the main symptom of scabies?
Intense itching, especially at night, with a raised rash or spots — often between the fingers, wrists, waist and groin.
Why must the whole family be treated?
The rash can take up to 8 weeks to appear, so others may already have mites. Treating everyone at once stops it passing back and forth.
Is scabies caused by poor hygiene?
No. The NHS says anyone can get scabies and it has nothing to do with poor hygiene.
How many times should scabies cream be applied?
Usually twice — the second treatment 7 days after the first, according to the NHS. Follow your doctor's or the leaflet's instructions.
Why am I still itching after treatment?
Itching can continue for a few weeks after mites die. See a doctor if you're still itching 2 to 4 weeks after finishing treatment.
Can I get scabies from my cat or dog?
No. The NHS says you cannot get scabies from pets.
