with other countries. This is probably the main reason for Korea’s success in
fighting the COVID-19 pandemic. Figure 6.7 shows much lower number of cases
in comparison with other countries with similar number of citizens.
Fig. 6.6 SIR curves (first epidemic waves, lines) and accumulated number of cases (markers)
versus time before March 1, 2020. Numbers of infected and spreading I (dashed) and victims
V = I + R (solid); “triangles” represent the V j values taken for comparisons. Colors correspond to
the country or region: world—brown; USA—blue; Italy—green; Spain—yellow; UK—red and
South Korea—magenta. The number of laboratory confirmed cases in Wuhan, China, is shown by
brown “squares”. These values were calculated in [69] with the use of information from [6]
