The current situation is in line with the latest reasonable worst-case scenario (RWCS), where incidence doubled once in August and once in the first two weeks of September, before re-imposed measures halt this growth. Under this scenario, there is an average incidence of approximately 11,900 infections per day for the second week of September in England. SPI-M-O’s estimated incidence range for England at present is 2,300 to 12,500 new infections per day, in line with estimates from ONS and REACT surveillance studies.
