These latest heat maps show how new cases of corornavirus are rising again across North Wales over the last week.

The latest Public Health Wales (PHW) data - set against colour coded maps - show how infections have been increasing over the region over the last seven days.

It comes amid concerns over a resurgence of the virus in parts of the country, which has seen local lockdown measures imposed in Caerphilly.

The Welsh Government is imposing new tougher rules on the wearing of masks in public and limiting the number of people that can gather indoors to six, coming into force on Monday.

First Minister Mark Drakeford warned mask rule flouters would risk fines up to nearly £2,000 as the country aimed to get ahead of a 'gathering storm'

Dr Robin Howe, Incident Director for the Novel Coronavirus (COVID-19) outbreak response at Public Health Wales, said:

“Public Health Wales welcomes the new action being taken from Monday 14 September by Welsh Government to prevent further rises in positive coronavirus cases. 

"These include the mandatory wearing of face coverings by people over 11 in public places, like shops, and that only six people from an extended household can meet indoors.

“As children return to schools, I understand that parents will be concerned at reports of positive cases.  I would urge you to follow advice from the school or local authority and only withdraw children from school when asked to do so. 

"Social distancing measures that are in place are designed to prevent the spread of the disease beyond the ‘bubbles’ established in schools.

“Again it is important that children maintain regular handwashing throughout the day, and on returning home, and parents’ help with this is vital.

“We are now seeing a steady increase in cases in a number of communities across Wales, and our investigations show that many of these have been transmitted due to a lack of social distancing."
