An "illegal gathering" is among the possible reasons for Newport's recent rise in infection rates, it has been claimed.
Newport has consistently had the highest rate of infection per 100,000 in the past week in Wales, having seen its rate rising steadily since the start of April. Read today's latest coronavirus stats here.
The city had a seven-day rolling infection rate of 29.7 cases per 100,000 on Tuesday, slightly down on the previous day when it was 34.9. Over the weekend, one area - Stow Hill - was reported as having the highest infection rate in Wales.
Although cases and Covid hospital admissions remain low across the country, the rise in Newport's rate of infection prompted the local authority and health officials to put the situation "under review " in late April.
2.3% of tests in Newport were returned as positive between May 7 and 13, ahead of Cardiff with 1.7%. Newport recorded five new cases on Tuesday, behind Cardiff with six.
In the seven days to May 12, the most recent data available, Stow Hill (10), Lliswerry & Uskmouth (8) and Pillgwenlly & Docks (8) had the most cases. Bettws recorded five cases and Caerleon, Rogerstone and Victoria & Somerton all recorded four cases. All the other areas had between zero and two cases.

What is behind the higher rates in Newport?
During his press conference on Friday Mr Drakeford said the Welsh Government and health authorities had been given information which said that the cases came from a number of “very local outbreaks".
"The advice I have had is that the numbers in Newport are explained by very local outbreaks like workplaces or care homes and in one case because of an illegal gathering," he said.
"All of them are known to the local public health authorities and are following the guidelines.
"All of them are being successfully followed up and the advice I have is they need to not be of a lot of concern to us as they are being monitored."
The first minister's comments follow on from those made recently by council leader Jane Mudd who said some people were "not adhering to all important social distancing rules" after the city recorded 40 cases in the last week of April, the second highest of any local authority in Wales.
Newport City Council said on Tuesday that it was "seeing evidence of transmission in some of our communities.
"Although new cases of Covid-19 remain low, we are still seeing evidence of transmission in some of our communities.
"Our track and trace service is very effective at identifying potential groups or linked cases. In such circumstances the council, with partners in Public Heath Wales and Aneurin Bevan University Health Board, work closely to identify the links and put measures in place to stop spread as quickly as possible.
"These can include improving access to testing with a local testing unit, further support through our track and trace team, working with local communities, schools, community leaders etc to ensure everyone has access to accurate information and support, working with local employers to support key messages and behaviour and ensuring venues are Covid secure."
The council added that it "remains very important" for people to continue to observe social distancing, wear face coverings and wash hands regularly, get a test if they have symptoms or feel unwell, isolate if required to do so and co-operate with Track and Trace.
How is the vaccine roll-out in the Newport area?
Aneurin Bevan University Health Board said on Tuesday that it had administered 543,988 vaccines so far. This includes seven out of 10 adults aged 30-39 years, while most people aged 70 and over (92%) and between 65 and 69 (80%) have received both doses of the vaccine.
On Sunday, PHW revealed that Wales had successfully vaccinated two million adults against coronavirus, including nearly one million who had received both doses. Read the full details here.
