Strep A test kits have sold out as demand drives prices to over £100.

Home tests for Strep A have sold out online amid concerns over the outbreak that has killed at least 16 children.

The swab kits had changed hands for more than £100 due to high demand, The Observer reported.

But its accuracy is uncertain and the Royal College of GPs says parents should see their doctor for a diagnosis if their child has strep symptoms such as a sore throat or high temperature.

Meanwhile, pharmacists continue to warn of a shortage of antibiotics to treat the infection.

Hannah Sami said her shop in Wilmslow, Cheshire, was out of amoxicillin.

Liquid penicillin is also said to be in short supply.

But NHS England medical director Sir Stephen Powis insisted there were plenty of medicines available.

“The government works with wholesalers. The supply chain is working well, I expect we will see deliveries to pharmacies as we speak,” he told BBC Sunday with Laura Kuenssberg.

The outbreak has put pressure on A&E departments.

Chloe Brewer, who took five-year-old son Hayden to Peterborough City Hospital with strep-like symptoms, told the mirror’s waiting families they had to sit on the floor for hours.
