Coronavirus and Science

As a scientist, I find it difficult to rationalize how some reject knowledge gained by a simple process of being careful about how things come to be known. Science is not some arcane unyielding body of knowledge but rather a process of ensuring that what we learn about something represents reality. There are numerous definitions of science but my favorite comes from the Nobel laureate Richard Feynman: science is what we do to keep from fooling ourselves.

The value of wearing a mask and social distancing as an effective means of disrupting the transmission of a serious disease comes from an understanding of the germ theory as shown by Louis Pasteur around 1860. This is nothing new and certainly not political. One hundred and sixty years of medical wisdom supports the fact that disrupting the transmission of an infectious agent is the way to prevent the spread of the disease. In this case, the infectious agent, SARS CoV-2 (the virus), may be new but how to address it’s spread is not.

Covid-19 (the disease caused by the virus) can go away but not by magic, rather by an informed and compassionate public taking the right steps to break the chain of transmission. Here in the United States, a relatively ill-informed public took half-hearted measures and then abandoned them too soon. New cases are on the rise both here in Arkansas and across the United States. More people are becoming ill and more people are dying because too many reject science. Too many people are rejecting hundreds of years of medical wisdom.

The leadership and citizens of much of the technologically advanced world get it. Life in New Zealand is back to normal as they are free of any new cases of Covid-19. The member states of the European Union have a larger population but hundreds of times fewer new cases. Meanwhile here in the United States, we are see-sawing in and prematurely out of closing down businesses to prevent disease transmission.

There is a furious global effort to develop a vaccine to combat Covid-19, but that can take a year or more to properly develop, test, and distribute. This could be the solution but again, reluctance to accept science stands in the way. Polling shows that up to fifty percent of the public will reject vaccination.

There is a long line of scientists; Pasteur, Jenner, Koch, Hooke, Harvey, Paracelsus, Vesalius, and on and on, and many more. More modern medical luminaries such as Reed and Salk and up to the present – Dr. Anthony Fauci . They all have provided the knowledge as to how we should address the pandemic if we care.

There is no alternate host, no reservoir for the coronavirus, it only exists in active cases. Stop transmission, and the disease goes away. It really is that simple.
