The World Health Organization (WHO) has changed its advice on face masks. They now say masks should be worn in public to help stop the spread of coronavirus.
The organisation said its new guidance had been prompted by studies over recent weeks. "We are advising governments to encourage that the general public wear a mask," Dr Van Kerkhove said.
At the same time, the WHO stressed that face masks were just one of a range of tools that could be used to reduce the risk of transmission - and that they should not give people a false sense of protection.
"Masks on their own will not protect you from Covid-19," said WHO Director-General Tedros Adhanom Ghebreyesus.
Non-medical vs Medical face masks
People over 60 and those with underlying health conditions, the WHO says, should wear medical masks when social distancing cannot be achieved. Our FFP2 face masks are medical grade face masks.
Others, not in this category should wear non-medical masks.
What are the new rules?
Compulsory face coverings on buses, trains, ferries and planes, and new rules for hospitals.
Some passengers will be exempt from the new rules:
Young children
Disabled people
Those with breathing difficulties
