Covid-19 Cases Are Rising Again Globally

After a period of decline, we are now seeing a rise in Covid-19 cases globally and in the U.S. According to WHO, there was a daily increase of 84,383 cases globally as of February 25, 2021, bringing the total number of current  global confirmed cases to 421,406. (Figure 1). John Hopkins is reporting 77,804 new cases in the US as of February 25, 2021. This demonstrates a steady increase from the 55,195 new cases reported in the U.S. on February 21, 2021, as seen in the chart below (Figure 2). A disturbing trend that should caution us against the complacency that some governors are showing by rolling back state Covid-19 restrictions.

As I have written in prior columns for Forbes, the increase in cases is likely due to the spread of the highly transmissible UK B.1.1.7, South African B.1.351, and Brazil P.1 variants. These dangerous variants have shown evidence of increased viral load which is associated with increased disease severity and mortality.
