Scabies
Scabies is a contagious skin condition that, while not typically serious, requires treatment to prevent potential infections from irritated skin.
It is caused by tiny mites that burrow into the skin and lay eggs. It’s important to note that scabies has no correlation with poor hygiene.
Risk Factors and Transmission
Scabies can affect anyone, with a higher risk among those who have frequent skin-to-skin contact or live in densely populated environments like schools, nursing homes, or crowded living spaces.
The mites favour warm areas such as skin folds, between fingers, under fingernails, or around buttock or breast creases.
Transmission usually occurs through direct skin contact, including sexual contact, though rare cases involve sharing clothing, towels, or bedding with an infected person.
What are the symptoms?
Symptoms of scabies, including intense itching (especially at night) and a rash where mites have burrowed, may take up to 8 weeks to appear.
While the rash typically spares the head, exceptions exist, particularly among older individuals, young children, or those with weakened immune systems. Scratching may lead to infection, potentially resulting in long-lasting marks.
How is scabies diagnosed?
Consulting a GP or sexual health clinician is necessary for confirmation of scabies. Diagnosis involves discussing symptoms and, in some cases, taking a skin sample for examination.
What treatments are available?
Treatment typically involves insecticide-containing creams to eradicate mites, with additional options available to alleviate itching. Pregnant or breastfeeding individuals should inform their healthcare provider.
After applying the cream, typically left on for several hours, a repeat treatment may be necessary a week later. While itching may persist post-treatment, lasting discomfort beyond four weeks warrants a doctor’s visit. Washing all bedding, nightwear, and towels at temperatures exceeding 50°C and sealing unwashable items in plastic bags for at least 72 hours helps prevent reinfection.
How can we prevent transmission?
To prevent reinfection, simultaneous treatment of all household members and close contacts, regardless of symptoms, is essential. Individuals with whom one has had sexual contact within the past 8 weeks should also undergo treatment.
Avoiding close bodily contact and refraining from sharing bedding, towels, or clothing until treatment completion and the resolution of infection further mitigates transmission risk.
