The focus in Shropshire has fallen on Craven Arms in the past few days, where 23 people at Long Lane Traveler tested positive for Covid-19.
The outbreak is associated with an outbreak in Welshpool on the Leighton Arches travel site.
Powys saw a significant increase in cases over the past week, with 15 positive tests in the past seven days – compared to 10 the week before.
The numbers mean the county has a rate of 15.9 cases per 100,000 population, well above Shropshire or Telford & Wrekin.
The latest seven-day average for Shropshire, measured on July 24th, shows a rate of 2.1 with 16 cases. However, on July 23, ten positive tests were recorded, the highest daily number since June 16.
So far, a total of 1,428 people in the county have tested positive since the outbreak began.
At Telford & Wrekin, the latest seven-day average is 0.6, with seven positive tests performed the week before July 24. A total of 626 positive tests were carried out in the district.

Questions are also being asked about an outbreak in Wrexham related to the Maelor Hospital. Llyr Gruffyd, a member of the Plaid Cymru Assembly for North Wales, said he asked for clarification of the spread of cases to community hospitals, including Chirk.
20 cases have been reported in the region in the past 48 hours, 53 in the past week at a rate of 39.
The increase has been linked to an outbreak at the Rowan Foods Factory, although there is evidence that many of those who tested positive were infected at Maelor Hospital.
Frank Atherton, Chief Medical Officer of Wales, said they believed that community transmission was related to both the hospital and the factory.
He said, "We believe that the community transmission is related to two things: the hospital and the meat packaging location."
In this situation, two mobile test sites were set up.
Dr. Arne Rose, medical director of the Shrewsbury & Telford Hospital NHS Trust, warned people not to keep the struggle for cover at bay.
It is because none of the trust's hospitals, Royal Shrewsbury Hospital or Princess Royal Hospital Telford, have had coronavirus patients in the "last days".
A total of 169 people have died of the virus since the Trust outbreak began, another 15 at the Shropshire Community Health Trust and five at Robert Jones and Agnes Hunt Orthopedic Hospital near Oswestry.
Dr. Rose said: "In the past few days we have been fortunate to have no patients in our hospitals, but all you have to do is look at the outbreak in Craven Arms to understand that we cannot be complacent.
"Indeed, it could be argued that this is a particularly risky time as people realize that the coronavirus has disappeared. It is not, and we must all continue to take the necessary precautions."
Stuart Bourne, director of public health for the Powys Teaching Health Board, said it was important that people who were in contact with those who tested positive self-isolation.
He said: "We all have a role in reducing spread.
"If you know you have been in close contact with someone who has tested positive, you should isolate yourself for up to 14 days.
"It is really important to do this even if you have no symptoms. If you are infected, you can become infectious to others at any time up to 14 days.
"Members of your family do not need to isolate themselves, but they should follow general social distance guidelines and avoid contact with you while isolating at home."
