It is a cancer type disease which occurs in blood vessels. It causes reddish purple, coin-size spots and lesion on the skin. b) Toxoplasmic encephalitis: Early evidence for HIV comes from studies of human blood stored sample of writing a thesis proposal, in Zaire in 1959. The spread of this disease can be prevented by: The full blown AIDS shows severe weight loss due to persistent diarrhea and some opportunistic infections. The destruction of immune system gives opportunity to some diseases. These are called opportunistic diseases. Some of these diseases are: (i) Avoiding sexual intercourse i.e. both vaginal and anal. d) Kaposi’s sarcoma: This type of pneumonia only occurs in AIDS patients. Article Shared by Sonali Priyadarshini The HIV was transmitted mainly by the following means: As per die common myth, HIV infection is not contagious as is measles, chicken pox, tuberculosis how write college application essay, cholera, plague, smallpox etc. The infection mainly spreads through a sexual route or blood to blood contact. HIV spreads mainly through sexual relationship-whether heterosexual or homosexual with an infected partner, transfusion of HIV infected blood and blood products college entrance essays, use of infected syringes or needles and is passed on by an infected mother to her unborn child. It is therefore, foolish to believe that HIV spreads through mosquitoes, embracing, holding, touching or kissing each other, shaking hands, coughing how to buy papers for college, sneezing, spitting help with paper app, sharing of public toilets or swimming pools, sharing meals or eating from the same plates, or sharing clothes, bedsheets or attending similar schools or working together. Two tests are carried out in order to confirm HIV infection—ELISA and Western Blot. ELISA is simple and the results can be known within a few hours but Western Blot is difficult, expensive and time consuming. It is carried out to confirm the first test. What had initially been thought of as a homosexual disease h» emerged as one of the most widespread one among men, women and children of ail ages. The diseases in many ways—strikes at the very foundation of the smallest unit of society – the family. The victims and their families go through a phase of emotional trauma write my essay for me in 3 hours, social isolation and are shatterred financially. The victims are removed form their jobs, disowned by their families and turned down everywhere. The facilities currently available are inadequate. More and more medical colleges, hospitals and counseling centres need to be developed. Some experts fear that a lower perception of vulnerability among circumcised men may result in more sexual risk-taking behavior, thus negating its preventive effects. Women who have undergone female genital cutting have an increased risk of HIV. Based on these studies, the World Health Organization and UNAIDS both recommended male circumcision as a method of preventing female-to-male HIV transmission in 2007. Whether it protects against male- to-female transmission is disputed and whether it is of benefit in developed countries and among men who have sex with men is undetermined. Consistent protection use reduces the risk of HIV transmission by approximately 80% over the long term. When one partner of a couple is infected, consistent protection use results in rates of HIV infection for the uninfected person of below 1% per year. There is some evidence to suggest that female protection may provide an equivalent level of protection. Programs encouraging sexual abstinence do not appear to affect subsequent HIV risk. Evidence for a benefit from peer education is equally poor. Comprehensive sexual education provided at school may decrease high risk behavior. (b) Hepatitis-B viral vaccine-Los Angles and New York (a) Polio, small pox vaccine from monkey’s kidney-Africa. Since its discovery business internship cover letter examples, AIDS has caused nearly 30 million deaths (as of 2009). As of 2010, approximately 34 million people have contracted HIV globally. AIDS is considered a pandemic —a disease outbreak which is present over a large area and is actively spreading. Image Source. medimoon.com If a person has at all developed AIDS, we should not discard him like a hot potato. He should be shown due regard and affection and we should take measures that we can for his comfort and recovery, if possible. We should remember that certain acts such as shaking hands, kissing, using same towels, etc. does not spread AIDS. There are two tests mainly used to detect the HIV and AIDS virus. The ELISA and the Western blot. ELISA stands for, Enzyme-Linked Immunosorbent Assay, it is an inexpensive test but often gives false positive diagnoses. When a positive result returns it’s often followed by the Western blot. This is a much more expensive and lengthy test that has to be interpreted by trained professionals. The major problem with HIV testing is that it often develops very slowly in the human body, staying virtually undetected for a long time. This is why so many people can be not carrying the disease without even knowing it. The virus normally enters the body through “internal linings of organs(such as the vagina in essays, rectum, urethra within the penis, or mouth)or through openings in the skin, such as tiny cuts or open sores.”(Kelly 534). It has also been proven that the virus can be transmitted from a mother to a baby via breast milk. It has also been shown that HIV can be found in urine how write personal essay, tears, saliva how do i write book report, and feces but no evidence of transmission through these fluids. There is hard evidence stating that HIV has been transmitted by the following; sexual intercourse, either anal or vaginal. Contact with vaginal fluid and semen, transplanted organs or blood from an infected person. The contact with infected blood psychology research paper writing services, the sharing syringes by drug users, tattoo needles that are not sterilized, etc. The HIV and AIDS viruses are technically more complex than what I explained. Now that I talked about what it does to the body I it’s very important to understand how it is transmitted from person to person. It has been documented that the HIV virus is transmitted by the direct transfer of bodily fluids. Those fluids could be either blood or sexually transmitted fluid. Since the virus can stay undetected in a carriers body it is often transmitted to others without knowledge. Those infected with the HIV virus and have acquired AIDS are more likely to transmit the disease compared to those without AIDS. This does not mean that the virus will not be transmitted at all. Once the HIV virus enters the body it infects the “T” cell the protectors of the immune system. Once they have attached to the T cell the HIV molecule sheds it’s outer coating and then releases the Viral RNA material into the T cell. RNA and DNA are basically genetic blueprints for the body. When the Viral RNA enters the T cell it begins transforming into the more complex Viral DNA. This occurs because the virus brings along an enzyme with it that causes the change. Modern medicine uses the drug AZT to put the transformation on hold. After the Viral RNA changes to Viral DNA it then penetrates the nucleus of the T cell. It connects with the cell DNA and awaits the opportunity to produce more Viral RNA. When the victim comes under stress or infection the cells break and become Viral proteins and begin making more Viral RNA. They are then re-coated so they can regain entry into other T cells, mass producing the virus throughout the immune system. There is still no really strong evidence that HIV has been transmitted through oral sex. Although there has been documented cases in which it has been transmitted from a male’s semen through oral sex. There is far less evidence of male’s or female’s contracting the virus through oral sex performed on a female. It has been said that the virus can not be transmitted trough kissing but experts can not rule out this possibility. Some have said that prolonged “French” kissing, open mouth with the switching of saliva, could possibly transmit the virus. There has been no evidence that casual contact has or ever will transmit the disease. This is were many social problems come into effect. Many be tend to isolate people that they know have contracted the virus because they are ignorant to how the disease is transmitted.
