Variants! The Shape-Shifting Challenge of COVID-19

People live in a sea of viruses. All creatures are host to these small organisms, which are made up of small bits of genetic information. Viruses are possessed by a drive to survive, but in order to reproduce they must invade a living cell.




Dr. William A. Haseltine, PhD, has spent a lifetime studying viruses and their ability to adapt and flourish within an ever-changing environment. In Variants! The Shape-Shifting Challenge of COVID-19, Dr. Haseltine turns his focus to SARS-CoV-2, the virus that causes COVID-19. The variant forms of this coronavirus risk an even greater disruption to our lives, our economy, and the health and wellbeing of hundreds of billions worldwide.




Variants! is a collection of Dr. Haseltine's writings and research on COVID-19 and SARS-CoV-2 mutations and variants. The book is a Living eBook, updated regularly with new information as it unfolds.
