Meanwhile, Karsons Pharmacy has issued advice amid an “increase in scabies cases across the island” over the past 12 months.
It said symptoms included persistent itching – particularly at night – as well as a red, bumpy rash, thin lines or burrows on the skin on the wrists, fingers, elbows or waistline.
Although scabies is “uncomfortable”, it is “fully treatable”.
The condition should be treated quickly to stop it spreading, the NHS advises.
People should go to their GP if they are under two months old, pregnant or breastfeeding.
People should also seek medical help if symptoms worsen or do not improve.
The same advice applies if there are signs of infection such as pain, spreading redness, discharge or fever.
