Scabies can lead to skin sores and serious complications like septicaemia (a bloodstream infection), heart disease and kidney problems. It is treated using creams or oral medications.
If left untreated, scabies can continue for many months. It is important to remember that recurrence of symptoms after attempted treatment does not exclude the diagnosis of scabies because patients may not have treated themselves correctly or may have been reinfested by an untreated contact.
Mites can survive for a few days without human skin. If a mite survives, you can get scabies again. To prevent this, you must wash clothes, sheets, comforters, blankets, towels, and other items.
Will scabies go away on its own? No, scabies won't go away on its own. If you don't treat it, you'll probably continue to spread the disease to other people. In addition, the constant itching will probably lead to constant scratching and will cause some type of bacterial infection of the skin.
If left untreated, the infestation may last for years, and has been called the seven year itch. This is a photomicrograph of a skin scraping that contains a scabies mite, eggs, and feces. This animal burrows into the skin, depositing both eggs and feces.
Scabies is prevented by avoiding direct skin-to-skin contact with an infested person or with items such as clothing or bedding used by an infested person. Scabies treatment usually is recommended for members of the same household, particularly for those who have had prolonged skin-to-skin contact.
Post-scabies syndrome is when you continue to experience a severe itch after you have been treated for scabies infestation. Post-scabies syndrome is due to an allergic reaction to the debris from the dead mites. Unfortunately, it can last for several months.
How long can scabies mites live? On a person, scabies mites can live for as long as 1-2 months. Off a person, scabies mites usually do not survive more than 48-72 hours. Scabies mites will die if exposed to a temperature of 50°C (122°F) for 10 minutes.
The scabies rash takes the form of small, red bumps that may look like pimples, bug bites, hives or knots under the skin. You might be able to see the burrow tracks created by the mites, which appear as raised lines of tiny blisters or bumps. Some people develop scaly patches that resemble eczema.

Scabies is highly contagious and is spread by close contact. If untreated, it can last indefinitely. Scabies is not caused by poor hygiene.
A study showed that tea tree oil was more effective in killing the scabies mites (scabicidal properties) than other commonly used agents. Moreover, it also showed minimum side effects during the trial. You may use tea tree oil as a natural home remedy for scabies by applying a tiny bit of this oil to your rashes.
Because the itching is caused by a reaction to the mites and their waste, it may continue for several weeks after treatment, even if all the mites and eggs are killed. Call your healthcare provider if the itching hasn't stopped 2 to 4 weeks after your treatment, or if you notice a new rash or burrows.
One treatment with a prescription anti-scabies cream usually helps. This usually kills all the scabies mites and eggs. Make sure you leave it on for 8-12 hours. The rash will heal up and go away in 2 weeks.
If you can't wash something in a washing machine, take it to a dry cleaner or seal it in a plastic bag for at least one week to kill the mites, which can't survive longer than three to four days without being on a human.
When a person is infested with scabies mites the first time, symptoms usually do not appear for up to two months (2-6 weeks) after being infested; however, an infested person still can spread scabies during this time even though he/she does not have symptoms.
The most common symptoms are: Blisters or bumps — Pink, raised bumps with a clear top filled with fluid are likely to appear on areas of the body where scabies have infested. Itching — A sensation of a foreign object crawling on the skin will create constant and sometimes severe itching, especially at night.
The itch of scabies is insidious and relentless. The itch is typically worse at night. For the first weeks, the itch is subtle. It then gradually becomes more intense until, after a month or two, sleep becomes almost impossible.
Because the symptoms of scabies are due to a hypersensitivity reaction (allergy) to mites and their feces (scybala), itching still may continue for several weeks after treatment even if all the mites and eggs are killed.
If pillows are not machine washable, put and seal them on separate plastic bags and store them for three weeks somewhere relatively unoccupied. Given that Scabies die within three days of non-contact with a human host, they won't survive at all after three weeks of storage.
A secondary effect of scabies is sleep deprivation, due to the itch which in turn can lead to low mood and the pruritus being viewed in more negative terms.
