Wales Health Minister Vaughan Gething has said "If the fall continues we can consider lifting restrictions in the Vale" - but cases have continued to rise since his tweets on Tuesday.
In a series of tweets on Tuesday, the Health Minister drew attention to the seven day case rate in areas under lockdown, which at the time showed 43.4 cases per 100,000 in the Vale of Glamorgan between 28th September - 3rd October.
Since then, figures released by Public Health Wales have been updated to include 4th October - seeing the seven day case rate in the County rising to 57.6 per 100,000.
In his tweets he pointed out the seven days case rates for the South Wales Counties under lockdown restrictions.
According to Public Health Wales figures from the 28th September - 4th October, the seven day cases rates are:
In a follow up tweet, the MS explained that "In the Vale of Glamorgan the figures went up over 50 per 100k and have now reduced."
"If the fall continues we can consider lifting restrictions in the Vale."
"We are at a point of a real risk with Covid increasing across Wales. Please follow the rules and do your part to #KeepWalesSafe."
But despite the positivity, yesterday Wales recorded the biggest daily increases in coronavirus cases in a 24-hour period since April - with cases continuing to rise in the Vale of Glamorgan.
