Who can forget the fearful experience of staying physically away from each other, going out with covered mouth and nose, and talking to people maintaining at least six feet distance during the biggest pandemic of the century, COVID-19? The "severe acute respiratory syndrome coronavirus-CoV2" was first found in Wuhan, China, and it took only a few weeks to reach every corner of the globe. Why earlier variants of SARS-CoV1 and MERS-CoV were stopped from spreading to the entire world but not SARS-CoV2 is a question for the public health field. The world knows it is extremely hard to contain infectious diseases in some geographical regions to protect the health of people at a global scale, so world leaders work together and come up with policies, international laws, and frameworks to stop the spread at the beginning level. This is one aspect of improving the health of people of the world and protecting them from a risk of contracting diseases, and so far, we have done phenomenal work in identifying pathways of infectious diseases and containing them with the help of immunization, prophylactic, medicines, and physical methods such as a condom for reducing the risk of HIV and sexually transmitted diseases. Despite being far advanced in technology and knowledge in managing and controlling the spread of infectious diseases, the world has experienced even greater tragedy and last 7,010,681 people, which is about 20 million more deaths than the influenza pandemic of 1918 that killed every third person in the world totaling 50 million people. Factoring population growth from 1.6 billion in 1915 to 8.1 billion now, the number of deaths from COVID-19 is proportionally lower, but this toll does not match the progress the world has made in improving health outcomes.
