Latest figures show the town’s infection rate is 233.8 per 100,000 residents - it was well above 3,000 at the start of the year.
It’s the lowest it has been since June 25 when the rate was 217.7.
Director of public health, Julia Burrows, said: “I know Covid-19 has brought difficulties to each of our lives in different ways.
“Beyond April, hopefully, the experience of managing the past two years living with it has taught us ways to reduce the risk of spreading and catching infections.
“This knowledge will provide us with better long-term protection from other illnesses, especially the importance of staying at home if we feel unwell.
“Safe behaviours have been our tools in successfully fighting the virus locally.
“Actions such as wearing a face covering, letting fresh air in, getting vaccinated and regularly washing our hands remain as relevant as ever.”
