Scabies

Scabies is transmitted by direct contact with an infected person. Spread through shared bedding and clothing is also possible. Re-infection can occur if other infected family members are not treated at the same time.

Skin rashes include scratched, red bumps and small burrows. Common areas affected are web spaces between the fingers and toes, wrists, ankles, armpits, waist and genitals.

Sometimes, after excessive scratching, bacterial infection can occur, and the rashes become weepy and painful.

After treatment, itching will improve but can last for up to a few months.

Topical permethrin cream: Safe for use above one month of age. Apply and leave on overnight, before washing off. For infants less than a year old, apply to the whole body including the scalp. In older children and adults, apply from the neck down. Repeat treatment one week later.

Topical malathion lotion: Safe for use above one year of age. Apply from neck down, leave on for 24 hours, before washing off. Treatment is recommended for two consecutive days. Repeat treatment one week later.

Topical benzyl benzoate: Not recommended for children younger than two years of age. Apply and leave on for 24 hours, before washing off. Apply for three consecutive days. Can be used in pregnant women.

All close contacts and members of the household (including helpers and grandparents) need to be treated with the abovementioned treatment to minimise re-infection. Bed sheets, linen and clothing require thorough cleaning, preferably in a washing machine.
