On Monday First Minister Mark Drakeford announced a 17-day “fire-break” lockdown for Wales which will run from Friday, October 23, at 6pm to Monday, November 9.
Mr Drakeford said it was critical to act now to reduce the rising rates of coronavirus in Wales.
- People in Wales are being asked to stay at home for more than two weeks from Friday at 6pm until Monday, November 9
- All non-essential retail, leisure, hospitality and tourism businesses will close as was the case during the March lockdown
- Community centres, libraries, and recycling centres will also all close and places of worship will be shut other than for funerals or wedding ceremonies
- Primary and special schools will re-open as normal after half term but secondary schools will only re-open to students in years seven and eight for the second week of the fire-break
- No gatherings will be permitted either indoors or outdoors with people from other households with the only exceptions being adults living alone and single parents who can join another household for support
Dr Robin Howe, incident director for the novel coronavirus outbreak response at Public Health Wales, said: “NHS Wales is still here to help you if you need care, and it’s important you continue to attend appointments and seek help for urgent medical issues.
“You can leave your home to access local health services, including your GP surgery, dentist, optometrist or other health service. You should phone beforehand and follow any guidance your local surgery, dentist, optometrist or health service has put in place to protect you and staff, including the need to keep 2m away from other patients.
“Public Health Wales supports the fire-break restrictions which are intended to disrupt the transmission of coronavirus in Wales. These restrictions will come into effect at 6pm tomorrow, Friday, October 23, and will last until the start of Monday, November 9.
“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.
“Although national and local measures have made a difference, further action is now needed. These new rules are vital to regain control of the virus, to protect the NHS, and save lives.
“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.”
