HIV is an incurable sexually transmitted virus that attacks and weakens the human system of a person. The human immune system is a complex system that fights infection, the body healthy. They say a person is infected with HIV HIV-positive.
What is AIDS?
AIDS stands for Acquired Immune Deficiency Syndromes. AIDS is a syndrome that the term for a variety of symptoms and effects that occur at the same time. AIDS is a range of symptoms, signs and tokens when the system arise from a person seriously weakened by HIV infection.
We can establish a diagnosis of AIDS in two ways. First, a person with HIV are diagnosed with AIDS if he or she contracts AIDS-defining illness. People with human systems are struggling usually in a position to AIDS-defining illness, but a person whose systems are characterized by weakened HIV, these diseases are very serious and can be dangerous to life.
To recognize the other way to fight AIDS is proof that a part of the human system of a person with HIV has weakened to a low level, so that the person susceptible to a variety of infections, diseases and cancers. Infections that cause disease in people with people are often "opportunistic".
Time interval between HIV infection and AIDS diagnosis:
It is very difficult to calculate with certainty the interval between the acquisition of HIV and AIDS diagnosis. On average (median), HIV takes to go more than 10 years from the state of AIDS. The range is different for each person and depends on many factors, including health and lifestyle of the person, the strength of the immune system with age and levels of immunity against other diseases. Another factor for the duration of treatment for HIV AIDS is always improving the effectiveness of antiviral drugs that slow the spread of HIV in the body. Since the development of these drugs for HIV treatment, people have more time before the infection becomes AIDS. Due to these factors and the effectiveness of drugs is constantly changing, no reliable estimates on the current average length of the progression of HIV AIDS.
