People who do not live in early hit cities may be at greatest risk during a second wave of COVID-19, according to new research from scientists at the University of Sussex and the Francis Crick Institute. Their research tracks the daily COVID-19 death rates in major cities (London, New York, Madrid and Milan/Lombardy) of four hard-hit countries, and compares it with the corresponding nations as a whole. They show that after lockdown—and indeed slightly before lockdown—death rates slowed more quickly in these early hit cities than in the rest of the population. The researchers conclude this is because coronavirus infection became more widespread in these main metropolitan regions, with the result that fewer people remained susceptible to infection and therefore COVID-19 was less able to spread.
