MORE coronavirus face mask rules and tougher social distancing measures are needed to prevent another lockdown as restrictions continue to lift, scientists have warned.
Experts say that tough measures should “increase in strength” in a bid to keep Covid under control as lockdowns are lifted across the country.

Modelling developed by scientists at the universities of Cambridge and Liverpool used mathematical equations to give insights about how Covid-19 will spread in different scenarios.
The scientists used examples of “non-spatial” control measures including face masks, hand washing and social distancing, and “spatial interventions” including lockdown and the restriction of long-distance travel.
The paper states: “Our results show that the reduction of spatial control without a simultaneous increase of non-spatial control inevitably increases disease incidence by increasing the reproduction number.
It comes as:
- Lockdown extension fears as Brits pack parks and beaches
- Mums warn of horror Covid-like virus running rampant in kids
- Mum left in agony with a burning rash due to 'severe jab reaction'
- Pfizer’s Covid vaccine is ‘100% effective in 12-15 year olds’
- Hope for summer holidays as UK vaccine success 'should open travel'
“Alternatively, it is possible to keep the reproduction number constant or even reduce it if non-spatial control interventions increase in strength while spatial control measures are being lifted.”
The modelling, published in the Journal of the Royal Society Interface, came from wider research looking at control strategies for plant diseases.
Study author Dr Yevhen Suprunenko, a research associate in the University of Cambridge’s Department of Plant Sciences, said measures such as face coverings, used properly alongside the vaccine rollout, could help to achieve a better outcome.
Dr Suprunenko said: “More effective use of control measures like face masks and hand washing would help us to stop the pandemic faster, or to get better results in halting transmission through the vaccination programme.
Alternatively, it is possible to keep the reproduction number constant or even reduce it if non-spatial control interventions increase in strength while spatial control measures are being lifted.”
“This also means we could avoid another potential lockdown.”
Dr Stephen Cornell, from the University of Liverpool and co-author of the paper, said while lockdowns might have a bigger impact, face masks and social distancing are cheaper actions people can take.
He added: “Measures such as lockdowns that limit how far potentially infected people move can have a stronger impact on controlling the spread of disease.
“But methods that reduce the risk of transmission whenever people mix provide an inexpensive way to supplement them.”
Professor Chris Gilligan, from the University of Cambridge’s Department of Plant Sciences – also a co-author – said the modelling could help find better ways to deal with future epidemics.
“Our new model will help us study how different infectious diseases can spread and become endemic,” he said.
“This will enable us to find better control strategies, and stop future epidemics faster and more efficiently.”
