A virus is a self replicating biological agent which can only reproduce within a single host organism. Viruses can infect various types of living things, such as plants, animals, and bacteria. The actual structure of viruses is so simple that even a child can recognize them. It is possible for a virus to mutate without causing any harm to its hosts, but sometimes this mutation causes the virus to affect its hosts in a way that is harmful. A virus can be called a “virus” if it invades and colonizes a living host (vasculitis, leukoplakia, etc. ).
There are many different types of viruses. Some viruses only reproduce by replicating themselves, while others will replicate using the protein coat of their host cell. When a virus uses its protein coat to reproduce, it is usually referred to as a “self replicating virus”. When a virus produces more copies of itself than it can tolerate, the virus will change into a disease causing virus.
Some of the most common viruses spread from one person to another through contact, such as through the air or via secretions of the nose. One type of cold virus, known as rhymes, only infects the nose. Some viruses will also infect the eyes, ears, mouth, and skin. The best way to prevent getting sick with any one of these viruses is to keep the immune system healthy. Keep in touch with your doctor on a regular basis and check yourself for common colds and flu symptoms. If you notice a strange sore/cold that doesn’t go away, see your doctor immediately because these could be signs of a more serious illness.
Many viruses make their way into the body through the food we eat. When a virus enters the body, it will attach itself to a host cell called a virus-carrier cell. The virus will then replicate itself inside the host cell until it is shut off by a protein call the “immune response”. This is the same response that causes shingles in humans. If the virus cannot enter the body, it dies off and the immune response goes into effect.
The immune response may also be triggered by exposure to bacteria or germs. Therefore, exposure to many different germs and bacteria can also result in the activation of the immune system. This allows the body to fight off the common cold and flu viruses. However, this protection doesn’t last forever. With this in mind, the body needs to be kept healthy so that the immune response can stay strong and fight off any new viruses may attempt to infect the body.
Some viruses are filamentous, meaning they have multiple layers of cellular membranes between their outer surface and the inner cellular layers. These viruses, which include retroviruses, envelop viruses, and enveloped plaques, are thought to be the cause of some cancerous conditions such as leukemia and lymphomas. There are also some non-filamentous viruses out there that have been shown to have the potential to cause certain health problems, such as HIV and HPV. Lymphoma is one example of a disease caused by filamentous virus.
