HIV AIDS disease causes Symptoms prevention and treatment

The human immunodeficiency virus (HIV) is a virus that infects humans and can lead to a state of advanced disease called acquired immune deficiency syndrome (AIDS). There are two types of HIV: HIV-1 and HIV-2. HIV-1 is more virulent and the dominant strain seen worldwide.

HIV is transmitted through bodily fluids (eg, semen, blood and breast milk) through activities such as sex, injection needle and breastfeeding. What makes this unique virus is its ability to evade the natural defense system of the body hiding in the immune cells called CD4 + T cells. In fact, HIV effectively hijacks these immune cells and uses them to replicate before destroying them.

AIDS occurs in the final stage of HIV infection when many immune cells are destroyed that the immune system can not fight disease. Although HIV and AIDS are often used interchangeably, it is important to know that refer to virus and disease in late respectively stage.

The first case of HIV in the United States dates back to the middle or end of 1970. According to the Centers for Disease Control (CDC), more than 1.2 million people in the US are currently living with HIV, with 50,000 new expected infections each year. In the United States, men who have sex with men are at highest risk of contracting HIV.

Globally, the World Health Organization (WHO) estimates that approximately 35 million people living with HIV / AIDS; of these, approximately 3.2 million are children under 15. HIV / AIDS remains a global health problem with low-income countries in sub-Saharan Africa are the most affected.

Without treatment, life expectancy of a person infected with HIV is 9-11 years. After a diagnosis of AIDS, life expectancy is reduced to less than 2 years. The cause of death is usually due to complications of certain cancers (such as Kaposi’s sarcoma and lymphomas) and opportunistic infections (eg, cytomegalovirus, tuberculosis, toxoplasmosis and cryptosporidiosis) arising because of defect in the immune system of the body.

There is no cure for HIV, but with proper treatment is called “antiretroviral therapy” (ART), it is possible to maintain a low viral count and live a nearly normal life expectancy up to 50 years. The best way to prevent HIV / AIDS is to avoid high-risk activities associated with the transmission of diseases, such as unprotected sex or sharing needles.
