Dr. Lewis discusses how viruses are part of our world and are often linked to chronic diseases and disability by the medical research community but not by doctors who treat patients. He discusses the U.S. healthcare system, SARS-CoV-2 Infection, COVID-19, coronavirus and also examines other viruses and their impact on human health. He also shows case studies of positive outcomes when infections are diagnosed and treated as causal agents. Paragraph Viruses, in our modern healthcare system, are assumed to cause “acute” or sudden illness, like COVID-19. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, smallpox, and Ebola. However, they also cause chronic conditions that the current healthcare system “manages” with drugs, rather than finding the cause and curing them. Here is a short list of common chronic diseases that have many peer-reviewed and evidence-based publications showing a connection between the disease and viruses: Cardiovascular disease – 1.3 million references; Cancer – 3.0 million references; Alzheimer’s – 185,000 references; diabetes – 2.2 million references; and autoimmune diseases – 1.3 million references. Paragraph Dr. Lewis presents several case studies on people with severe diseases who were cured by treating underlying infection including viruses.
