A virus infection is caused by an agent that can only replicate inside the cells of other organisms.
They are so small, they can be easily missed even under a light microscope, and affect all types of living organisms. Around 5,000 viruses in total have been discovered. They consist of a few parts and contain genes from RNA or DNA and have a protein that protects them. It is unclear where they come from. Viruses can be spread in many ways from coughing or sneezing to fecal matter transfers. They can also enter the body through food or drinking water.
More serious viruses can be transfered through sexual bodily fluids or exposure to blood that has been previously infected. They provoke the immune system and can usually be eliminated by it. Other viruses like viral hepatitis or HIV can invade and result in chronic infections with no cure. Some antiviral medications have been developed for some of the milder infections to aid in virus removal. These medications cannot help in the removal of all viruses because of their inability to fight against the virus reprogramming capabilities.
There is a cycle that viruses adhere to. After attaching to the cellular surface which determines what virus will develop. An example of this is human immunodeficiency virus or HIV. It only attacks human immune cells or T cells because of its specific protein make up. Once attached, it enters the hose through receptors and degrades the coatings. After entering, it begins to replicate these proteins and genetic material. When these processes are completed, they cause cell ruptures and escape from the host.
The most commonly known viruses include the common cold, mononucleosis, cold sores, influenza, and chicken pox. Virus symptoms can overlap and are often overlooked. Our immune systems work to fight against each of these viruses and medications like antibiotics will not help with these viral infections. Fever, headaches, swelling of the sinus cavities, nausea, coughing, and sneezing are all common symptoms. As the immune system weakens from the fight, we become tired and require rest. The consumption of liquids is important with any of these viral infections to prevent dehydration. Many of these infections will cause a decrease in appetite, so our bodies lose nutrients that are necessary. Vitamin supplements can be useful to aid in the body’s natural virus removal. Discussing virus symptoms with a physician is the best route, so the correct diagnosis and preventive methods can be taken.
Vaccines are available for specific viral infections like influenza, hepatitis, and the chicken pox. Many of these infections are recognized by the body and immunity can be built up. Each virus attacks the body differently and can affect us from weeks to months before we are rid of the infection. Diet and exercise are important to keeping our immune systems healthy. Proper hygiene is necessary to prevent these virus germs from entering our systems. Chronic infections can break down the body and carry fatality risks. Understanding how to prevent a virus infection is necessary and following guidelines will lower anyones risks of disease.
