An article on AIDS -Introduction - how is it caused? -What are its symptom? -How can it be prevented?

Answer 1

The virus can be found in the blood, semen, vaginal fluid, and breast milk of infected people. HIV is also found in saliva, sweat, and tears, though not in high enough amounts to transmit the virus to another person. There are no known cases of anyone catching HIV through sneezing, shaking hands, or from toilet seats or mosquito bites.The two most common ways to be infected with HIV in North America are through unprotected sex and sharing needles. HIV may be transmitted through unprotected heterosexual or homosexual, vaginal, anal, or oral sex. Although the risk of infection is lower with oral sex, it is still important to use protection during oral sex, such as a dental dam (a piece of latex to cover the vagina during oral sex) or a condom. HIV can also be passed on through perinatal infection, where mothers who have HIV are at risk of giving the disease to the baby during birth. The risk of perinatal infection is declining with new treatments. Breast-feeding by an infected mother can also transmit HIV.

Answer 2

AIDS - Acquired Immuno Deficiency Syndrome is a pandemic and a life threatening condition to many people all over the world. It is a viral disease caused due to the Human Immunodeficiency Virus ( HIV ). This virus targets the CD4 lymphocytes in the body and brings overall suppression of the immune system. Since this virus mutates, it has been difficult to devise a vaccine for this disease. The condition manifests its symptoms after a brief incubation period in the form of fever, diarrhea, unexplained weight loss, tuberculosis and the patient is prone to develop other infections like candidiasis and kaposi sarcoma. The primary mode of transmission of this disease is through sexual contact. It can also be transmitted by transfusion of HIV infected blood to a non infected patient or by sharing of needles or syringes. It can also be transmitted from the infected mother to the fetus through the placenta. The best way to eradicate this disease is "prevention". People need to be educated about the dos and donts of HIV transmission. Providing proper sexual education may also help. Drugs like Zidovudine and Saquinovir are increasingly used in the treatment of this disease.
