The history of the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) dates back to 1981, when homosexual men with symptoms of a disease that now are considered typical of AIDS were first described in Los Angeles and New York.
Ever since, the world has suffered with this dreaded disease. Lives have been lost, destiny’s changed and the catastrophe long lived. However the herculean effort from all the frontiers of medical science to have ever existed, has brought us to the day, where at least life can be prolonged and a life of dignity and respect and be enjoyed.
The stigma and mental blocks that go with the disease needs to be removed. We have moved on since 1981. The prevalence of AIDS in Dakshina Kannda district has come down to 0.25 per cent in 2011 from the 0.75 per cent as recorded in 2008, thanks to the efforts of the District AIDS and Prevention Control Unit, which is striving hard to spread awareness and support people with HIV.
On occasion of the world AIDS Day, it is worth to recall and remember the ways in which HIV spreads.
HIV is present to variable degrees in the blood and genital secretions of virtually all individuals infected with HIV, regardless of whether or not they have symptoms. The spread of HIV can occur when these secretions come in contact with tissues such as those lining the vagina, anal area, mouth, eyes or with a break in the skin, such as from a cut or puncture by a needle. The most common ways in which HIV is spreading throughout the world include sexual contact, sharing needles, and by transmission from infected mothers to their newborns during pregnancy, labor (the delivery process), or breastfeeding.
Sexual transmission of HIV has been described from men to men, men to women, women to men, and women to women through vaginal, anal, and oral sex. The best way to avoid sexual transmission is abstinence from sex until it is certain that both partners in a monogamous relationship are not HIV-infected. If abstinence is out of the question, the next best method is the use of latex barriers. This involves placing a condom on the penis as soon as an erection is achieved in order to avoid exposure to pre-ejaculatory and ejaculatory fluids that contain infectious HIV. For oral sex, condoms should be used for fellatio (oral contact with the penis) and latex barriers (dental dams) for cunnilingus (oral contact with the vaginal area).
The spread of HIV by exposure to infected blood usually results from sharing needles, as in those used for illicit drugs. HIV also can be spread by sharing needles for anabolic steroids to increase muscle, tattooing, and body piercing. To prevent the spread of HIV, as well as other diseases including hepatitis, needles should never be shared.
There is little evidence that HIV can be transferred by casual exposure, as might occur in a household setting. For example, unless there are open sores or blood in the mouth, kissing is generally considered not to be a risk factor for transmitting HIV. This is because saliva, in contrast to genital secretions, has been shown to contain very little HIV. Still, theoretical risks are associated with the sharing of toothbrushes and shaving razors because they can cause bleeding, and blood can contain large amounts of HIV. Consequently, these items should not be shared with infected people. Similarly, without sexual exposure or direct contact with blood, there is little if any risk of HIV contagion in the workplace or classroom.
The symptoms of hiv and AIDS differ, depending on the stage of the infection. Initially with HIV, there may be no symptoms at all, although one of the most common symptoms is mild fever 3–6 weeks after getting infected.
Sometimes symptoms can show up after 8 or 9 years or more. Some of the symptoms of hiv infection are fever, sore throat, headache, swollen lymph glands, rash, cough, diarrhoea and weight loss.
Trends continue toward simplifying drug regimens to improve adherence and decrease side effects. In addition, the availability of multiple new drugs in new classes has made it possible to suppress viral load to undetectable levels even in many of the most treatment-experienced patients. With such great success in treatment, the field has increasingly considered strategies that may someday allow patients to control viral replication without the use of antiretrovirals. This could be in the form of a true cure with complete eradication of HIV. Human efforts in various formats should yield a breakthrough, sooner or later. Till then, stay safe and stay careful.
