Introduction HIV infection this slowly progressing viral disease of immune system The stage of HIV infection at which because of decrease in immunity the person has secondary infectious or tumoral diseases, is called as acquired immunodeficiency syndrome (AIDS). ВИЧ-инфекция это медленно прогрессирующее вирусное заболевание иммунной системы Стадия ВИЧ-инфекции, при которой из-за снижения иммунитета у человека появляются вторичные инфекционные или опухолевые заболевания, называется синдромом приобретенного иммунодефицита (СПИД).
AIDS was first reported in the United States in 1981 and has since become a major worldwide epidemic. AIDS is the most advanced stage of infection caused by HIV. The names HIV and AIDS can be confusing because both terms describe the same disease. But most people who are HIV positive do not have AIDS. An HIV-positive person is said to have AIDS when his or her immune system becomes so weak it can't fight off certain kinds of infections and cancers, such as PCP (a type of pneumonia) or KS (Kaposi sarcoma, a type of cancer that affects the skin and internal organs), wasting syndrome (involuntary weight loss), memory impairment, or tuberculosis.
Even without one of these infections, an HIV-positive person is diagnosed with AIDS if his or her immune system weakens, as indicated by the number of CD4 cells in his or her blood. A CD4 cell count less than 200 in an HIV-infected person gives someone a diagnosis of AIDS. It can take between 2 to 10 years, or longer, for an HIV-positive person to develop AIDS if he or she is not treated. Most people with HIV will not develop AIDS if they start treatment (with medicines called antiretroviral therapy or ART) soon after becoming infected. Once a person has been diagnosed with AIDS, she or he is always considered to have AIDS, even if that person's CD4 count goes up again and/or they recover from the disease that defined their AIDS diagnosis.
The spread of HIV/AIDS has affected millions of people worldwide; AIDS is considered a pandemic.  In 2009, the World Health Organization (WHO) estimated that there are 33.4 million people worldwide living with HIV/AIDS, with 2.7 million new HIV infections per year and 2 million annual deaths due to AIDS.  In 2007, UNAIDS estimated: 33.2 million people worldwide were living with HIV; AIDS killed 2.1 million people in the course of that year, including 330,000 children, and 76% of those deaths occurred in sub-Saharan Africa.HIV/AIDSpandemic World Health OrganizationHIV UNAIDSsub-Saharan Africa
According to the UNAIDS 2009 report, some 60 million people worldwide have been infected with HIV, resulting in approximately 25 million deaths and 14 million orphaned children in southern Africa alone since the epidemic began decades ago.
Misconceptions about HIV and AIDS arise from several different sources, from simple ignorance and misunderstandings about scientific knowledge regarding HIV infections and the cause of AIDS to misinformation propagated by individuals and groups with ideological stances that deny a causative relationship between HIV infection and the development of AIDS. Below is a list and explanations of some common misconceptions and their rebuttals.deny
Conclusion Unfortunately, so far it isn't developed an effective HIV vaccine though in many countries careful researches in this area on which lay hopes are now conducted. К сожалению, к настоящему времени не разработано эффективной вакцины против ВИЧ, хотя во многих странах сейчас проводятся тщательные исследования в этой области, на которые возлагают большие надежды.
