The expert’s advice comes amid an uncharacteristic surge in chickenpox cases, as rates are usually lower during the summer months. Chickenpox is one of many vaccine-preventable diseases seeing a resurgence since lockdown measures were lifted. The varicella-zoster virus, which also causes shingles, usually causes fairly mild illness. However, the infection may be transmissible even before the first stage of the disease initiates, warned Doctor Zoe.

The expert added that children should avoid scratching their rash, as this could result in permanent scarring.
Covering the hands with mittens or socks at night time, and the use of cooling gels can help prevent this.
Chickenpox, which afflicts thousands in the UK each year, is usually treated with calamine lotions.
