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.
- The factors that cause the disease AIDS
There are several ways and events included in the causes of AIDS. In the world there are several factors that come into the causes of AIDS. Every day AIDS is increasing and making people and killing them and their families. AIDS is the sixth leading cause of death among people 25-44 years old.
HIV is transmitted in many ways, such as oral sex, anal, vaginal, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth and lactation.
HIV (HIV) causes AIDS. common microbes, yeast, insect and viruses that often cause serious illness in people with strong immune systems can cause fatal illnesses in people with AIDS.HIV originated in saliva, tears, nervous system tissue and cerebrospinal fluid, blood, fluid vaginal and breast milk. However, only blood, semen, vaginal secretions and breast milk has been shown to transmit infection to others. AIDS is transmitted through sexual contact, through blood, from mother to child methods .Other the spread of the virus are casual contact such as hugging, mosquitoes, touching things were touch by an infected with the virus. AIDS is also spreading through intravenous drug users who share needles.
AIDS is a dangerous disease when people seriously ill and suffering patient. They do not feel active and healthy and also suffer from laziness and cutting pains in different parts of the body. AIDS symptoms are important opportunistic infections, skin cancer and eye infection, weight loss, and brain tumors. AIDS is different in every infected person. Only a few people die within a few months after contracting the infection and others live a fairly normal life for many years.
Other symptoms include fever, sweating, swollen lymph nodes, joint pain, mouth disorders, fungal infection, pain, loss of consciousness,
and inability to control muscles People who are infected with HIV may have no symptoms for ten years or more, but can still transmit the infection to others during this phase without symptoms. You may not know if infected by HIV. Some people have fever, headache,
pain in muscles and joints, stomach ache, swollen lymph glands or a skin rash for one or two weeks. To really know that you should be tested for HIV AIDS virus correctly.
