Wales has now entered a 17-day "fire-break" lockdown which will last until Monday, November 9.

Everyone is expected to stay at home wherever possible, non-essential retail will shut, and secondary schools will close for those in year nine and above. Read the full announcement here.

Speaking on Monday, health minister Mr Gething said: "We are facing a real public health emergency in Wales – we have a two-week period in which we need to do everything we can to break the cycle of transmission and do everything we can to bring coronavirus under control.

"We are moving very swiftly towards the April peak – the point at which the NHS came very close to being overwhelmed. But in the spring we had already postponed all planned operations and appointments.

"If we carry on at this rate we will reach this point within a matter of weeks."

It was announced on Tuesday that volunteers are being sought to test a potential new vaccine against Covid-19.

Public Health Wales and Betsi Cadwaladr University Health Board are looking for people to take part in a clinical trial which will examine its effectiveness.

Experts state that the vaccine has already shown promising initial results on antibody levels in healthy volunteers and no serious safety concerns have been identified to date.

It now requires testing on a large scale and a study involving 9,000 people in around 18 regions across the UK has been launched.

The aim is to recruit volunteers aged between 18and 84 who live within a 30-mile radius of Wrexham to take part.

The study will involve volunteers making six visits to Wrexham Maelor Hospital over approximately 13 months. Reasonable travel expenses will be reimbursed. You can read more about it here.

Dr Robin Howe, incident director for the novel coronavirus outbreak response at Public Health Wales, said: "Public Health Wales is reminding people that fire-break restrictions came into effect in Wales on Friday, October 23, and will last until the start of Monday, November 9.

“We urge the public to stick to the new rules, which are vital to help us regain control of the virus, to protect the NHS, and save lives.

“Although national and local measures have made a difference further action is now needed. Cases continue to rise in Wales, hospital admissions are increasing, including those into critical care, and sadly so are the numbers of people dying from the virus.

“Under the rules people must stay at home except for very limited purposes. They must not visit other households or meet other people they do not live with.

“Certain businesses and venues, including bars, restaurants and most shops, must close.

“Secondary schools will provide learning online only for the week after half term other than for children in years seven and eight. Primary schools and childcare settings will remain open.

“Face coverings continue to be mandatory in the indoor public spaces that remain open, subject to certain exemptions and exceptions, including on public transport and in taxis.

“More information about the new rules is available at the Welsh Government website."
