Virus: The smallest form of microorganisms capable of causing disease. Especially, a virus of fecal origin that is infectious to humans by waterborne transmission.
Viruses: The smallest life forms known, that are not cellular in nature. They live inside the cells of animals, plants and bacteria and often cause disease. They are made up of a chromosome surrounded by a protein shell.
virus An intracellular parasitic microorganism smaller than bacteria and containing either RNA or DNA.
viruses
A group of infectious agents consisting primarily of a genome that replicates itself within a host cell by using its nucleic acids to direct the host cell to synthesize more viral nucleic acids and proteins.
Virus-like particle (VLP): Genetically engineered spherical protein envelope derived from a virus; does not contain viral genetic material and cannot replicate but elicits a potent immune response.
...
Virus A submicroscopic genetic constituent which can alternate between two distinct phases. As a virus particle, or virion, it is DNA or RNA enveloped in an organic capsule.

Since a portion of the groundwater source's recharge is from surface water, the groundwater is at risk of contamination from pathogens such as Giardia lamblia and viruses, which are not normally found in groundwater.
Once our body has been invaded, the immune system copies the invading body and our defence mechanism so that should we be invaded again we are ready to attack. The reason why AIDS has taken on such importance in the last few years is that the virus ...
