One of the
British government’s scientific advisers has said repeated “mini lockdowns” could be effective as a tool to bring Covid-19 cases under control.
The suggestion from Prof John Edmunds, a member of the government’s Scientific Advisory Group for Emergencies (Sage), comes amid growing evidence the virus’s prevalence is growing among older, more vulnerable people.
A circuit breaker, or mini-lockdown can be used to reset the clock. The idea would be to bring the incidence back to what it was a few weeks earlier. You replace two weeks of exponential growth with two weeks of a decline in cases.
This can have a big effect on the total number of cases, particularly if it is implemented shortly after the epidemic starts to grow.
A reporting team at the Observer have put together a longer read meanwhile on how Britain finds itself in a situation where infections are starting to dramatically rise again at a time when other nations have managed to stabilise or suppress the spread of the virus.
But they also note that scientists are still arguing over the reasons some countries seem to have been spared heavy death tolls even as the infection spreads.
A relatively young population may be less vulnerable than in fast-ageing western disease hotspots. People living in overcrowded conditions may have stronger immune systems, fortified by fighting off many past infections. But if it is hard to predict how Covid epidemics will develop, it is much easier to see what keeps the disease at bay.
The few countries that have managed to effectively eliminate coronavirus range from authoritarian
China to liberal democracies such as
