Note the dark blue line. It represents the whole world caseload of people who have been diagnosed with the Covid disease. The black line below it shows the total number of victims who have died of the pandemic disease. Note that the United States has the worst caseload and death load of any country and that it is progressing at a steeper growth rate than all large population countries except Brazil. Note also that China put a sudden end to the Covid pandemic. It is not erased completely and it never will be, as it will lurk for a long time as does the common cold. Vaccination will help, but it won’t eliminate the disease.
The best option for people these days is to avoid other people with the Covid disease and to clean their sinuses with a mild soap suds made of baby shampoo.
