Statement issued on behalf of the Director for Public Health in Worcestershire, Dr Kathryn Cobain;
Dr. Kathryn Cobain, Director for Public Health in Worcestershire said; “R rates are calculated nationally and regionally. Data is drawn from many official sources and the process is complex and robust. Here in Worcestershire, we fall under the Midlands region for this data, and this includes a very large area, across the East and West Midlands.
It is not possible to calculate a meaningful R rate at a very local level, for example in cities such as Worcester. An R rate even at County level would not be a reliable and robust interpretation of the data.
This is because the data gathered is at such low numbers that even a minor change can create a disproportionate difference. Locally we review a multitude of early warning indicators, and look for signs of change. We continue to monitor the situation closely to ensure the safety of our residents.”
