Powys residents are being urged to remain Covid-safe after a spike in case numbers particularly among children.
The county has seen more than a 50 per cent increase in COVID-19 cases with secondary school age children particularly affected.
Case rates have rose steadily for younger age groups in Powys over recent weeks - on a rolling seven-day basis the county has a case rate of 531.6 cases per 100,000 residents.
But in the 10-19 age bracket, the case rate has surged to 1,970 per 100,000 for the week beginning October 10.
In comparison, the case rate is 218 for those between 20 and 29, 459 for those in their 30s, and 517 for those in their 40-49 bracket.
The age group with the second highest case rate is under-10s, whose case rate now stands at 837 per 100,000 people.
A spokesman for Powys County Council said: “Parents and guardians are being urged that if a child has a high temperature, a new continuous cough, or a loss or change to their sense of smell or taste, they ensure that they isolate immediately and get a PCR test.
“In addition, twice weekly LFD testing is strongly encouraged for all secondary school age learners to help identify and isolate asymptomatic cases as soon as possible.
“The huge increase in case numbers is also having an impact on the county’s dedicated contact tracing team which is being stretched by the volume of cases. It has asked residents to be patient warning that calls may be delayed but that the team is working hard to reach contacts.”
