Due to their miniscule size, it was not until 1885 that Adolf Mayer observed their existence in the mosaic (leaf-spot) disease of the tobacco plant, which he described as to be caused by a strangely invisible contagious agent.1 This particular living entity was so small that it readily passed through a porcelain filter. With the invention of the electron microscope by Ernst Ruska, the virus' true anatomy was first time visible to us in 1933.2 They are so infinitesimal that billions could fit into a drop of water---or a drop of human blood. Viruses have the most exquisite ability to sense the right cell surfaces. They don't just cause diseases in people, they infect every form of life on earth. Some emerging viruses are very serious. Common examples are the hepatitis viruses, B and C. The hepatitis B pattern of illness was re
