To diseases caused by viruses, they are known as diseases or viral infections. These are caused by infectious agents that live and propagate into living cell units. Flu virus. These infectious agents are known as viruses. A virus can be defined as a microscopic pathogen, much smaller than most bacteria Mandal, They consist of a coating of protein and genetic material inside. Viruses are the most numerous biological structures on the planet, being very dangerous for humans because they can cause infections and diseases of all kinds.

A disease does not always appear when a virus is acquired, because the immune system may be able to fight it. However, some viruses can attack certain cells, multiply within them and propagate. Cells of the immune system attacking viruses. For the generality of viral diseases, treatments only improve symptoms while the immune system attacks the virus. Antibiotics do not work for viral infections. There are antiviral medicines to deal with and vaccines can make it more difficult to spread.

Viruses can remain in the cell without damaging it, making it a carrier. The patient appears healthy, but infection may occur after a latency period Medline Plus, In the organism it can give a form of immunity that lasts a long time, because the virus enters, the organism confronts it and it remembers producing specific antibodies against him avoiding to re-acquire it.

These infections are very common and any sexually active person can get it, especially if you have many sexual partners.
