 A virus (from the Latin virus meaning toxin or poison) is a microscopic organism consisting of genetic material (RNA or DNA) surrounded by a protein, lipid (fat), or glycoprotein coat. Viruses are unique organisms because they cannot reproduce without a host cell. After contacting a host cell, a virus will insert genetic material into the host and take over the host"s functions. The cell, now infected, continues to reproduce, but it reproduces more viral protein and
genetic material instead of its usual products. It is this process that earns viruses the classification of "parasite". How are viruses spread? Viruses may spread vertically (from mother to child) or horizontally (from person to person). A virus"s ability to spread depends on the makeup of the virus. Interesting articles What are bacteria?

assistance and manufacturing of the vaccine provided by the NIH, according to Anthony Mbewu, president of South Africa"s Medical Research Council.
