Viral infection ? Top symptoms of viral infection

Infection refers to the invasion of our body by any disease causing organism, their multiplication and production of toxins. There are several different types of viruses that can infect our body. While many of these viruses only result in a mild infection that often resolves by itself, few of them may cause fatal infections. Further, symptoms of viral infection may not be noted in all. Hence, it becomes important to know about viral infections.

Viral InfectionHow do viruses infect us?

Viruses enter a normal living cell and then use these cells to multiply in large numbers. While doing this they can kill the cell, alter its functioning or cause it function excessively or minimally. Eventually, such a viral infection can make you sick. These viruses can often attack specific organs in your body, such as the lungs, liver, or even the blood.

Does viral infection always make us ill?

The body’s self-protection system, known as the immune system, can ward off several viral infections. Vaccinations can also help prevent many infections by strengthening the immune system. However, you can get ill when the immune system is not able to handle the infecting virus. These can result in the symptoms of viral infection.

What are the symptoms of viral infection?

Common cold, flu and warts are some of the common viral infections. Such infections are generally associated with symptoms such as fever, cough, chills and cold. The viruses causing these infections can spread from one person to another commonly through the body fluids expelled during a cough or sneeze. Some of the viruses can cause severe conditions such as AIDS, smallpox or Ebola. These infections are associated with a wide variety of symptoms ranging from fever to severe disability. Sharing needles, sexual intercourse with an infected individual or bites from infected animals can also cause the spread of viral infections.

Can the symptoms of viral infections indicate something dangerous?

It needs to be remembered that symptoms of viral infection can be the same as that noted during any other infection. There are no specific symptoms which can separate viral infections from other infections. In some cases there may be no symptoms during the initial stages of the viral infection; the symptoms appear only in advanced stages.

How are viral infections treated?

Viral infections cannot be cured with antibiotics; they need to be treated with antiviral drugs. However, such medications are only available for infectious conditions such as hepatitis (certain types), influenza, herpes and HIV (ongoing research). There are certain vaccinations also available to prevent the occurrence of some viral infections. Nevertheless, common viral infections such as cold and flu subside by themselves. Only supportive treatment to treat the symptoms of viral infections such as fever may be indicated in these cases.

Nevertheless, always consult your doctor if you feel that you have been ill for longer than 2-3 days and much earlier if you have some severe symptoms.
