The South Hams has seen one case of COVID-19 confirmed this week, with two historic cases removed as duplications.
Across Devon and Cornwall there has been a small rise in cases, 32 this week compared to 29 the previous seven days.
It means the average number of cases being confirmed across the two counties each day has risen to 4.57 from 4.14, although not all of the newly confirmed cases related to recent infections.
Of the 31 new cases, 18 of them had the specimen recorded in the previous seven days (between July 17 and July 23), with the remaining 13 cases having occurred between July 11 and July 16.
In the last seven days, there have been ten cases confirmed in Cornwall, five cases confirmed in Plymouth, and three in Torbay, although two historical duplicates for Torbay have been removed.
Across the rest of Devon, 15 cases have been confirmed, with four in East Devon, five in Exeter, three in Mid Devon and four in Teignbridge. The South Hams saw one new case confirmed, but two historical duplicate cases have been removed, while North Devon, Torridge and West Devon saw no new cases confirmed.
Torridge remains the district in England with the lowest positive case infection rate of anywhere in England per 100,000 population, with the South Hams 3rd, North Devon 4th, West Devon 5th, East Devon 8th, Cornwall 9th, Teignbridge 10th, Exeter 15th, Torbay 21st, Plymouth 37th, and Mid Devon 40th out of the 315 English council districts.
Torridge has also had the fewest number of cases of any of the districts, with West Devon 2nd, and the South Hams and North Devon also in the bottom five.
In total, Torridge has had just 53 positive cases, with 72 in West Devon, 98 in the South Hams, 119 in North Devon, 210 in Mid Devon, 213 in Teignbridge, 219 in East Devon, 244 in Exeter, 277 in Torbay, 668 in Plymouth and 909 in Cornwall and the Isles of Scilly.
