Covid face masks are set to make a return as the World Health Organisation releases new advice.
The virus has spread rapidly through the world yet again after the mass lifting of restrictions in China.
On top of this, the XBB.1.5 strain is expected to sweep across Europe in just weeks, as experts fear the strain is the most transmissible yet.
A study by the Nature Medicine journal predicted that the entire population of Beijing will have been infected by Covid.
That amounts to a staggering 22 million citizens.
In their attempt to curb the spread, the WHO has urged people to return to mask wearing if they are in crowded places, enclosed places, or places where there is poor ventilation.
They have called on countries to consider recommending that passengers wear masks on long-haul flights too.
They have also recommended that patients who have symptoms of Covid but are not able to test, isolate for ten days .
If an individual tests negative they can leave isolation early.
Total Covid-19 infections in the UK fell at the start of the month, suggesting the current wave may have peaked – though levels have yet to start dropping in every part of the country.
There has also been an “encouraging” decrease in the number of patients in hospital with the virus according to experts.
