Corona waves
The graphs showing
new daily corona cases and new daily deaths exhibit distinct and separate peaks in all countries over the last year of the pandemic, corresponding to
several waves of Covid-19 infection (see Worldometers under individual countries). In many
countries, the 1st wave occurred around April, the 2nd around August, the 3rd around November 2020, and the 4th around January 2021 (see Table 1).
