Viral Infections In most types of viral infection, the immune system clears the virus from the body within days to a few weeks. But some viruses cause persistent or latent * infections, which can last for years. In these cases, a person may get infected and seem to recover or may not be aware of being infected at all.

Microbes are tiny organisms that cannot be seen without a microscope and include bacteria, fungi, and some parasites, as well as viruses. viral infection occurs when a virus enters the body through such processes as breathing air contaminated with a virus, eating contaminated food, or by having sexual contact with a person who is infected with a virus.

- Viruses are capsules with genetic material inside. They are very tiny, much smaller than bacteria. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, smallpox and hemorrhagic fevers. Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This eventually kills the cells, which can make you sick. Viral infections are hard to treat because viruses live inside your body's cells. They are protected from medicines, which usually move through your bloodstream. Antibiotics do not work for viral infections.

Information on the different types of viruses and types of viral infections The common cold is a frequently occurring viral infection and usually includes symptoms such as sneezing, stuffy nose, sore throat and coughing. Although colds are a minor infection of the nose and throat, a cold can last from two days to two weeks. viral infection is any type of infection that is caused by a virus, which is even smaller than bacteria and is encapsulated by a protective coating, so it is more difficult to kill than bacteria. Viral infections involve a dormant virus getting into a living cell and re-writing the cell's genetic codes with its own.

Viral Infection Rash A viral rash is typically caused due to two types of viral infections. They include infection of the skin caused by a virus, and other types of infections which are caused due to a combination of bacterial and viral infections. The two most common types of viral skin infections are chickenpox and measles. When the skin rashes occur along with these two common symptoms, then it is most likely to point to an infection of the body by viruses, and that the rash is most likely to be a viral rash. 2  A majority of patients are also likely to experience other symptoms such as abdominal pain, and muscle aches and pains.

Viral Meningitis Facts & Information Viral infections are the most common cause of meningitis, with bacterial infections being the second most common cause. Additional and more rare causes of meningitis include parasites, fungi, and causes that are non-infectious such as ones related to drugs. Meningitis caused by a viral infection is sometimes referred to as, 'aseptic meningitis,' and is serious, although rarely fatal in people with average immune systems. The symptoms of viral meningitis usually last between 7 and 10 days, and people often experience a complete recovery.
