Types of Viruses
Many people believe that viruses are all bad and have no good things to offer. But viruses can have good results, as well. And sometimes viruses are even beneficial to mankind, and that’s why some viruses are considered good. For example, the SARS virus, or better known as a form of herpes, has helped a lot of people’s control and even stop the spread of herpes.
First off, what is a virus? Viruses are viral content contained in an object, cell, or bodily fluid. They are very important to living things, since they provide the body with the nutrients it needs to survive. Viruses use a particular method to accomplish this: through a process called replication. They divide themselves many times, and then their offspring (strangely identical copies) reproduce even more.
How do viruses infect living organisms? Well, like most other pathogens, viruses attack living organisms by causing a swelling of their membranes, or covering the entryways to their cell bodies. When they infect a cell, it is commonly referred to as infection. These viruses can invade virtually any type of cell – even the ones that are not part of our own body! The type of cell that they infect generally determines how the virus affects that organism. For instance, some viruses may infect the red blood cells, or the lymphocytes, which are part of the immune system.
There are several different types of viruses. The most famous ones are; AIDS, SARS, and M AIDS. There is also a disease which is caused by a strain of hepatitis B virus, and is referred to as Hepatitis B Virus Type 1, or BVDV. There is also a strain of retrovirus which causes an infection named Retroviruses, such as Human Immunodeficiency Virus or HIV.
Since viruses can affect any type of cell, it is important to know that viruses can affect you. This will help you in taking steps towards protecting yourself from the illness. First, since all viruses affect the genetic makeup of their host organism, it is possible for one to develop immunity to these particular viruses. Similarly, some viruses (such as AIDS) cannot be passed on to others by any type of physical means.
It should also be noted that the various different types of viruses are spread through a number of different means. For instance, some viruses only need to be injected into a host cell, while others will need to be invaded by cells from another source, before spreading into a new host cell. This can include airborne, blood, or even oral routes. Additionally, some viruses are silent, meaning that they remain in the host cell without producing any noticeable effects, and then cause the disorder. Some types of silent viruses include bacteria, retroviruses, and plaques. Although there is currently no cure for most viruses, research is constantly being done to find better ways of preventing, detecting, and treating virus infections.
