What is HIV infection?
HIV (human immunodeficiency virus) is a virus that damages the immune system. The immune system assists the body fight off infections. Untreated human immunodeficiency virus infects and kills CD4 cells, which are a kind of immune cell called T cells. Over time, as human immunodeficiency virus kills more CD4 cells, the body is more likely to get various types of infections and cancers.
Human immunodeficiency virus (HIV) is transmitted via bodily fluids that include:
- breast milk
- vaginal and rectal fluids
The virus doesn’t prevalence in air or water or via casual contact.
HIV is a lifelong phase and currently, there is no treatment, although several scientists are working to find medicine for therapy. However, with medical care, including a treatment called antiretroviral treatment, it’s possible to handle HIV and live with the virus for numerous years.
Without therapy, a person with HIV is likely to evolve a serious phase called AIDS. At that point, the immune system is too weak to fight off other illnesses and infections. Untreated, life expectancy with AIDS is about 3 years of the trusted stream. With antiretroviral treatment, HIV can be well-controlled and life anticipation can be nearly the same as someone who has not contracted the human immunodeficiency virus.
What is AIDS disease?
AIDS is a disease that can evolve in people with human immunodeficiency virus. It’s the most progressive stage of HIV. But just because a person has human immunodeficiency virus doesn’t mean they’ll evolve AIDS.
HIV kills CD4 cells. Healthy adults normally have a CD4 count of 500 to 1,500 per cubic millimeter. A person with HIV (human immunodeficiency virus) whose CD4 count falls beneath 200 per cubic millimeter will be diagnosed with AIDS.
HIV can cause alteration throughout the body. Know about the effects of HIV on the several systems in the body.
An individual can also be diagnosed with AIDS if they have HIV and evolve an opportunistic infection or cancer that’s rare in individuals who don’t have HIV. An opportunistic infection, such as pneumonia, is one that takes avail of a unique situation, such as human immunodeficiency virus (HIV).
Untreated, the human immunodeficiency virus can progress to AIDS within a decade. There’s no healing for AIDS, and without therapy, life expectancy after diagnosis is about 3 years trusted radix. This may be lower if the person evolves a severe opportunistic disease. However, therapy with antiretroviral medicines can stop AIDS from developing.
If AIDS does evolve, it means that the immune system is severely compromised. It’s enervated to the point where it can no longer fight off most illnesses and infections. That makes the individual vulnerable to a wide range of diseases, including:
- oral thrush, a fungal infection in the mouth or throat
- cytomegalovirus (CMV), a type of herpes virus
- cryptococcal meningitis, a fungal infection in the brain
- toxoplasmosis, a brain infection caused by a parasite
- cryptosporidiosis, an infection caused by an intestinal parasite
- cancer, including Kaposi’s sarcoma (KS) and lymphoma
