How Does Scabies Spread?
Scabies is usually passed from an infected person to others during prolonged, direct skin-to-skin contact like holding hands.
It takes about 10 minutes of contact for the mite to pass from the infected host to another person.
Scabies is easily passed among people who share the same household.
Scabies infestations can be found in places where people interact and live in crowded conditions.
Children can become infected with scabies by their parents.
Among young adults, the disease is often spread during sexual contact.
Crusted scabies are more common among people who have a weakenedimmune system.
How Long Is Scabies Contagious?
If you have scabies, you’re considered contagious until you receive your first treatment.
The time between infestation and symptoms is called theincubation period.
The first time you have scabies, it can take four to eight weeks for symptoms to appear.
If you’ve previously had a scabies infection, symptoms typically emerge within four days after exposure.
Once you are infected, you could spread the disease even if you don’t have symptoms.
The eggs hatch and create new adults that burrow within two weeks.
Their babies maintain the cycle of burrowing and egg-laying until the entire infestation is treated.
Your immune system recognizes the mites and their waste as potentially dangerous organisms, which triggers a response.
This results in the itchy, red rash that is common with scabies.
If your diagnosis is unclear, your healthcare provider may take askin biopsyto confirm the presence of mites.
In this procedure, a sample of tissue is removed to be analyzed in a laboratory.

This prevents the spread of the disease and your reinfection.
A Word From Verywell
Having scabies can be frustrating.
The itching can be intense, especially at night, which can interfere with sleep.
To kill the mites, it’s important to get an accurate diagnosis and treatment as soon as possible.
This also reduces the risk of skin damage from scratching or rubbing to relieve the itching.
