The week ending September 27 saw Barnsley’s cases at 76.6 per 100,000, but just a week later the cases were at 141.4 per 100,000 in the borough.
In the last two weeks Covid-19 cases in adults aged 40 to 59 have been recorded more than in any other age group - residents who are 80 to 99 years old saw the least number of cases.
Julia Burrows, director of public health for Barnsley, said: “We’re sharing this data as we want to be as open and transparent as possible and know that many of you are concerned about the recent rise in the number of positive cases in the past couple of weeks.
“Please note that the seven-day rate of new infections may change as more cases are reported.
“The information in this summary is provided in order to show the trends and give the people of Barnsley an up to date picture of the current rate of cases.”
Barnsley Council will be sharing a daily figure on their social media accounts to track the seven-day rate of new infections per 100,000 people in the borough.
