Health officials have confirmed that Wales has 12 new cases of coronavirus, taking the total to 136.

Ceredigion still only has one confirmed case, whilst there are no reported cases in Gwynedd at present.

Powys and Carmarthenshire both have seven cases, with Pembrokeshire having two.

Dr Giri Shankar, incident director for the Novel Coronavirus (Covid-19) outbreak response at Public Health Wales, said: “We can confirm that 12 new cases have tested positive for Novel Coronavirus (Covid-19) in Wales, bringing the total number of confirmed cases to 136.

“As we are currently only testing within hospitals, this is likely to underestimate the true number of cases.

“The advice for the public has changed.

· People are being advised to stay at home for 14 days if they, or anyone in their household, has either a high temperature or a new and continuous cough

· People are now being advised to avoid non-essential contact with others and unnecessary travel

· People are being asked to work from home where they possibly can, and avoid pubs, clubs, theatres and social venues

· People in at-risk groups will be asked within days to be largely shielded from social contact for 12 weeks

“People no longer need to contact NHS 111 if they think they may have contracted Novel Coronavirus (Covid-19).

"People with a fever or persistent cough should stay at home for seven days if they live alone, or 14 days if they live with others.

"Anyone who lives with someone displaying coronavirus symptoms should also stay at home for 14 days. They should not go to a GP surgery, pharmacy or hospital.

“They should only contact NHS 111 if they feel they cannot cope with their symptoms at home, their condition gets worse, or their symptoms do not get better after seven days.

“The public play an important role in the ‘delay’ phase. By following the latest advice, you will protect yourself, protect the most vulnerable, and delay and flatten the peak, which will reduce the pressure on NHS Wales and minimise the impact of the virus.

“We continue to undertake priority testing in Wales. We are working closely with health boards, NHS 111 and the Welsh Government to develop systems so that NHS Wales and members of the public have appropriate access to Novel Coronavirus (Covid-19) testing.”
