Wales is set to tighten Covid restrictions to tackle a rising number of hospital admissions.
Adults who are fully vaccinated, and young people aged five to 17, will be asked to self-isolate until they have received a negative PCR test if someone in their household has symptoms or tests positive for Covid-19.
People who are not vaccinated will still have to self-isolate for 10 days following contact with someone who has tested positive, including close contacts outside of their household.
Head teachers will be given extra support to quickly put measures in place in their schools if case rates are high locally.
Staff and secondary school students will also be encouraged to take twice-weekly lateral flow tests to help keep coronavirus out of schools.
The Welsh Government also intends to extend the use of the Covid Pass to theatres, cinemas and concert halls from November 15.
However, the country will remain at alert level zero.
The First Minister, Mark Drakeford, said: “Over the past three weeks, coronavirus cases have risen sharply to the highest rates we have seen since the pandemic began and more people are falling so seriously ill that they need hospital treatment.
“All this means that the pandemic is far from over. We need to take more action now to strengthen the measures we have in place at alert level zero to prevent coronavirus spreading even further and more people falling seriously ill.
“We hope this action will help to turn the tide of this delta.
“None of us wants to see a return to restrictions but, if rates continue to rise, the Cabinet will have no choice but to consider raising the alert level at the next review.
“Let’s all work together as a team to reduce the spread of coronavirus and keep Wales open and keep Wales safe.”
The Welsh Government is also continuing to encourage everyone to work from home wherever possible and is still imposing a legal requirement to wear a face covering in indoor public places.
