The spread of HIV from person to person is called HIV transmission. The spread of HIV from a woman with HIV to her child during pregnancy, childbirth, or breastfeeding is called mother-to-child transmission of HIV.

Reported AIDS cases may be separated into groups based on these risk factors: homosexual or bisexual males–75%, intravenous drug abusers with no history of male homosexual activity–13%, Haitians with neither a history of homosexuality nor a history of intravenous drug abuse–6%, persons with hemophilia A who were not Haitians, homosexuals, or intravenous drug abusers–0.3%, and persons in none of the other groups–5%.

After HIV infection is confirmed, your doctor will start you on a drug regimen consisting of several drugs; combinations of different types of anti-HIV drugs sometimes are called HAART, for highly-active antiretroviral therapy (HIV is a kind of virus called a retrovirus).
Stevenson took out his phone and opened Jack’d, a hookup app popular with men of color. He pulled up his “professional” profile — on which he’s smiling, clean-cut and buttoned-up amid a sea of bare chests and crotch shots. At the bottom he had put a link to a website with information about PrEP; next to it he’d written: “Inbox me if you want to know more.” “I’ve gotten a bunch of messages asking about side effects, how much it costs and does it work,” Stevenson said. He and Watson said they take the medication “just in case.”
Founded in June 1987, South Side Help Center (SSHC) is purposed to help people of all ages embrace a lifestyle of prevention against mental, physical and social ills by providing positive, healthy alternatives so that community residents can lead productive lives. SSHC purpose and legacy is in serving the people of the community. We actualize our mission of “Providing people with positive and healthy alternatives” through many programs and services.

respiratory syncytial virus (RSV) any of a genus of single-stranded paramyxoviruses; the name is derived from the type of disease produced (respiratory infection) and the microscopic appearance of the viruses in cell cultures. RSV can cause a wide variety of respiratory disorders ranging from a mild cold to serious or even fatal disease of the lung in the very young and very old. It regularly produces an outbreak of infection each winter and virtually disappears in the summer months. The most severe infections in children are in the very young, especially those who are preterm, immunologically compromised, or suffering from a congenital heart defect or preexisting lung disorder. Adults at risk for infection include parents and others who are repeatedly exposed to young children, for example, pediatric nurses and day care attendants. The course of infection tends to be milder in adults than in children and about 15 per cent of adults have no symptoms. In the very elderly these infections may have the same degree of seriousness and clinical manifestations as in the very young.
In addition, 1 in 3 people living with HIV present to care with advanced disease, at low CD4 counts and at high risk of serious illness and death. To reduce this risk, WHO recommends that these patients receive a “package of care” that includes testing for and prevention of the most common serious infections that can cause death, such as tuberculosis and cryptococcal meningitis, in addition to ART.
The second most frequent mode of HIV transmission is via blood and blood products. Blood-borne transmission can be through needle-sharing during intravenous drug use, needle stick injury, transfusion of contaminated blood or blood product, or medical injections with unsterilized equipment. The risk from sharing a needle during drug injection is between 0.63 and 2.4% per act, with an average of 0.8%. The risk of acquiring HIV from a needle stick from an HIV-infected person is estimated as 0.3% (about 1 in 333) per act and the risk following mucous membrane exposure to infected blood as 0.09% (about 1 in 1000) per act. In the United States intravenous drug users made up 12% of all new cases of HIV in 2009, and in some areas more than 80% of people who inject drugs are HIV positive.
Healthcare visits in the preceding year were associated with a lower rate of unawareness (37% vs 81%) but a higher rate of HIV-positivity (21% vs 12%). Because this study targeted a high-risk group and may involve participation bias, the overall rate of HIV infection (19%) cannot be easily extrapolated to the overall population. 
According to the August 2008 report issued by the Joint United Nations Programme on HIV/AIDS (UNAIDS), as of 2007, approximately 33 million people worldwide are HIV positive. Over half of the 33 million are women and this statistic has remained stable for several years. The highest number of cases is found in sub-Saharan Africa and Southeast Asia.
Screening antibody tests or newer combination antigen/antibody tests should be offered routinely to adults and adolescents, particularly pregnant women, regardless of their perceived risk. For people at highest risk, especially sexually active people who have multiple partners and who do not practice safe sex, testing should be repeated every 6 to 12 mo. Such testing is confidential and available, often free of charge, in many public and private facilities throughout the world.

Non-nucleoside reverse transcriptase inhibitors. This class of drugs binds to an enzyme that is necessary for the HIV virus to reproduce. Examples of drugs in this class are viramune, delavirdine (Rescriptor), and efavirenz (Sustiva) and others.
Sturdevant drove on another 15 minutes to pick up Marq (a shortened version of his name to protect his privacy), a teenager who was still reeling from the H.I.V. diagnosis he received the previous spring. As they headed to and from a doctor’s appointment and a meeting with a counselor, Sturdevant, slow-talking and patient, with eyes that disappear into his cheekbones when he smiles and a snowy beard, gently grilled him, reminding him to stay on his meds. The teenager slumped in the back seat, half listening, half checking his texts. He looked up briefly when Sturdevant told him, “You’ve come a long way. I’m proud of you.” But Marq barely said goodbye as he jumped out of the car in front of a convenience store on an avenue scattered with a pawnshop, a liquor store and several Baptist churches, and he all but admitted he was planning to spend the afternoon smoking weed and looking at Instagram. “Knucklehead,” Sturdevant whispered, as the teenager slammed the door. Pulling off his favorite Dallas Cowboys baseball cap and running a hand over his bald head, Sturdevant added softly, “Breaks my heart.”

Testing and diagnosis of HIV-exposed infants has been a challenge. For infants and children less than 18 months of age, serological testing is not sufficient to identify HIV infection – virological testing must be provided (at 6 weeks of age, or as early as birth) to detect the presence of the virus in infants born to mothers living with HIV. However, new technologies are now becoming available to perform the test at the point of care and enable return of the result on the same day to accelerate appropriate linkage and treatment initiation.
It is extremely important that patients take all doses of their medications, otherwise the virus will rapidly become resistant to the medications. Therapy is always given with a combination of antiviral drugs.
Macrophages and dendritic cells seem to be able to harbor replicating virus without necessarily being killed by it, and are therefore believed to be an important reservoir of infection, as well as a means of spreading virus to other tissues such as the brain. Although the function of macrophages as antigen-presenting cells does not seem to be compromised by HIV infection, it is thought that the virus causes abnormal patterns of cytokine secretion that could account for the wasting that commonly occurs in AIDS patients late in their disease.
HIV may be the human version of simian immunodeficiency virus (SIV), known to infect African chimpanzees. It may have crossed over and mutated in humans who ate infected chimpanzee meat as long ago as the late 1800s.
In September 2014, new UNAIDS “Fast Track” targets called for the dramatic scaling-up of HIV prevention and treatment programmes to avert 28 million new infections and end the epidemic as a public health issue by 2030.93
Immunodeficiency disorders are either congenital or acquired. A congenital, or primary, disorder is one you were born with. Acquired, or secondary, disorders you get later in life. Acquired disorders are more common than congenital disorders.

Syndrome is a collection of symptoms, or problems in the body. Because the immune system is damaged, and cannot fight off disease, people with AIDS get a collection of symptoms which is referred to as the “Acquired Immunodeficiency Syndrome.” [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
