What PCR Can—and Can’t—Tell Us About COVID-19: Understanding Ct Values and Contagion

PCR (Polymerase Chain Reaction) is a powerful tool used to detect genetic material, but it's often misunderstood when applied to diagnosing infectious diseases like COVID-19. To understand its limitations—and why a positive result doesn’t always mean someone is contagious—we first need to look at how PCR works and what the test results really mean.

Masks cannot prevent respiratory infections

This article will show how respiratory diseases are spread via dry aerosols produced during ordinary breathing. It will show how virions can stay airborne for many hours after they have dried whilst exiting the body. It will show that masks do not protect against bacterial or viral infections. It will show that masks can sometimes exacerbate disease and will cause ill-health.

Koch’s postulates fulfilled for 2019-nCoV-2.

Developed in the 19^th century, Robert Koch’s postulates are the four criteria designed to assess whether a microorganism causes a disease. As originally stated, the four criteria are:-

(1) The microorganism must be found in diseased but not healthy individuals.

(2) The microorganism must be cultured from the diseased individual.

(3) Inoculation of a healthy individual with the cultured microorganism must recreate the disease.

What is Coronavirus and 2019-nCoV?

This article will use a time-line of science studies in date order to explain how the understanding of coronavirus has evolved. It will explain the basic understanding of viruses and show that they are classified into families. It will explain how viruses spread and the impact they can have of society and also explain the long lasting neurological damage that can be done when we catch a common cold.
