One hundred seventy years ago, tuberculosis was a lethal disease. This illness posed a significant threat to humanity, resulting in an estimated 1 billion deaths between 1700 and 1900. Notably, traces of tuberculosis have been found in the mummies of ancient Egyptian kings.

This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
