Even before the knowledge of science exists, these things such as viruses already exsisted.....the scientist will know in time.
2,000,000
Viruses have the ability to greatly affect life on earth. Many viruses, such as HIV and influenza have killed millions of people. By studying viruses, scientists are able to develop vaccines that will protect people (and animals) from viruses.
Bacteria, fungi, algae, protozoa and virus
Bacteria and viruses attack the body. Each type of bacteria and virus attack different areas of the body. Also, there are many different ways of gaining access to the body. They attack the body by trying to shut down a certain system, which without your immune system, would kill you. Bacteria and viruses evolve. However, viruses aren't presently categorized as living organisms.
virus consists of different parts: 1)Viral genome2)Capsid3)Envelopes or Covering4)Tail fibresVIRAL GENOME: it is the inner part,the nucleic acid.it consists of a single or many molecules of DNA or RNA. In small virus four genes and in the largest virus several hundred molecules are present.In many viruses nucleic acid is different. In animal viruses and bacteriophage usually DNA is present and in plant viruses mostly RNA is present. In viruses cytoplasm, nucleus and chromosomes are not found
because viruses change everyday a virus is made that we haven't found out about

Computer viruses are currently unable to spread to humans.
Because viruses originated from a variety of host cells.
Scientists do not know how many viruses there are because new ones are constantly being made from old ones joining.

Some scientists are hoping that viruses can be modified to undo damage by other viruses, but there is no actual working "damage control" virus available as of July of 2013. Many scientists are concerned that even the good virus might have unwanted side effects.
There are many different types of scientists because one person could not handle all the information of geology, astrology, and other types of science. Since there are numerous types of sciences, there has to be many different types of scientists, so there are many different scientists because there are many different sciences.
a virus consists only of a single strand of genetic material, while a cell consists of genetic material, a nucleus, and many organelles that all have different functions. because of a viruses lack of materials, scientists debate whether they are actually living things or not.
Many different scientists.
There's so many here's a few:TrojanWormBloodhoundBeastThose are the most common and dangerous viruses.
