Viruses are mostly dead, but it is very real in nature. They are the result of an experiment gone wrong. One virus infects a cell while another mutates into a pathogen, a type of disease-causing bacteria. The pathogen can then invade other cells and cause disease.

Viruses are t technically alive; though this remains a largely hypothetical question; they simply re merely packets of cellular genetic information. Some carry only that genetic code in single genetic strands of DNA, others in multiples of DNA or even in viral DNA strands. But generally they all use these genetic instructions as a guide for invading healthy cell, or hosts, as is the case when a pathogen mutates into a disease-causing bacteria or virus. A pathogen cannot by itself reproduce, though it can multiply, causing a multiplication of viruses. So it is an invading entity; it can also be passed on from one cell to another in a biological experiment.

There are various different kinds of viruses that have an effect on cell types. The two most common are: retroviruses and bacteriophages. Retroviruses are extremely damaging to healthy cells and so they should be cleared out by killing the host. If this happens the invading virus can be killed and the harm it causes to other cell types can be stopped. In some cases, especially those with multiple types, the viruses are not killed, and so continue to replicate and cause harm to other cells.

Bacteriophages are not truly a virus, but they do have the ability to replicate. They can attach themselves to a host cell, where they will replicate until the envelope has been completely detached. Once this has occurred, then the cocoon (the envelope) is released, and the bacterium becomes a virus. These are known as envelopaviruses. It is possible for a bacteriophage to become airborne during an outbreak and for this to happen they release particles into the air.

Virus replication is necessary in order for the virus to survive. Otherwise, the virus could not survive contact with any other viruses or bacteria that may be present in the environment. For example, if you were looking to develop a vaccine against a newly developing disease, you would need to first make the virus itself, and then inject the weakened body cells into a healthy person. This would help the virus gets into the body and start reproducing. Then once the infected person is able to excrete the virus from their body the vaccine would be effective.

There are different ways in which these viruses get into a person’s body. Some are through dirt and germs, which can pass onto a surface and begin reproducing themselves. Other types come through an injury or touching an object contaminated with the virus. There is also a possibility that these tiny little viruses get into a person’s ear and begin reproducing in the ear canal. All of these methods of entering the body can cause problems to the immune system of the human body.
