how aids develops?

Answer 1

adids delops mainly by-

1 sexual contact with infected person
2 by needles of injections or infected blood
3 frm infected mother to child

Answer 2

AIDS starts out as first with a person becoming HIV positive- that's the virus. The virus camps out in your body for quite some time, multiplies and such, has a grand ol' time. Then once it's multiplied and caused enough damage to your immune system it's classified as AIDS- Acquired Immune Defiency Syndrome... or something, I'm kinda drunk right now.

Answer 3

aids virus lives in blood of humans and apes:it is spreaded by sexual intercourse with the infected person ie when transmission of body fluids occures;when a syringe used by infected person is used without sterilisation the virus attackas;it is inherited from infected mother to the baby since inside the womb blood transmition b/n them occures.it is to be noted that aids is not propagated through mosquitos or throug water or air and surely you can hug and kiss babies with this disies that only spreads love;aids virus distroys the immune system so the patient after long or short no of years is attacked by tuberculosis (mainly)and other diseases which causes death

Answer 4

aids is acronym for Acquired Immuno Defeciency Syndrome. the name of the infecting virus is human immuno virus. aids develops mainly due to unprotected sex. the various stages are, the virus after entering the body infects the t cells which are important for the immune system as these are the cells which signal an infection as the virus destroys these cells slowly the body losses immunity and the bacteria in the environment attack the body due to weak defense and thus the man dies not due to the hiv virus but due to other diseases

Answer 5

once the virus has entered ur body .
aids till now is uncurable.it attacks the immune system of the body and wbc production is reduced due which the patient gets al sorsts of diseases fm minor to major and all affect the body adversely .that s how aids develops.

Answer 6

Aids develops over time. the main ways to spread aids are:
1. sexual contact (sex)
2. drug-needles
3. blood mixing - when to people cut themselves open and transfer blood between each other
4. babies can be infected at birth by - mothers milk or body flu eds
5. in very rare cases, by transference

Answer 7

It is caused by a virus that was trasmitted from Monkeys in Africa to humans. Normally it does not happen, because it mutated to somehting different but primarily stayed the say with the ability to cross over to humans..Just like the scare in China Avion-flu. it is a virus that normally affect birds, but is also mutated and now can infect humans too..

Answer 8

The three main transmission routes of HIV are sexual contact, exposure to infected body fluids or tissues, and from mother to fetus or child during perinatal period. It is possible to find HIV in the saliva, tears, and urine of infected individuals, but due to the low concentration of virus in these biological liquids, the risk is negligible.

Answer 9

ATHENS, Ohio – More than 90,000 people in the United States are over the age of 50 at the time they are diagnosed with AIDS and at least 25 percent of them suffer from depression. But a new Ohio University study suggests that a telephone support group can lessen stress and improve the coping skills of older adults living with the disease.

In the pilot study, which will be presented this Saturday at the National Association of HIV Over Fifty Conference in Scottsdale, Az., 23 older adults who had been diagnosed with depression participated in a 12-week telephone support group. The participants, who were recruited through AIDS service organizations in Ohio, New York, Pennsylvania and Arizona, discussed life stressors and issues related to aging with HIV/AIDS. Licensed social workers offered advice about coping mechanisms and ways to seek support for health problems.

Those involved in the 12-session program reported greater reductions in stress and suicidal thoughts and an increase in coping skills, compared to a control group of 21 people who did not participate in the support group, said Timothy Heckman, an Ohio University health psychologist and lead author of the study.

The telephone intervention program appealed to participants who were too geographically remote from or physically unable to drive to standard support groups or counseling services, as well as those who were concerned about confidentiality issues. The telephone is one way to circumvent some or all of those barriers, Heckman said.

“Many of our participants noted that they don’t have to dress up, drive in and try to present a good image when everything is not well,” he said. “The telephone is financially and psychologically easier.”

The study is funded by a two-year, $435,000 grant from the National Institute on Aging to evaluate the ability of the telephone-delivered mental health intervention to improve the quality of life of older persons living with HIV/AIDS who have been diagnosed with depression. In a previous study supported by the National Institute of Mental Health, Heckman found that the phone support group was successful in reducing depression and increasing social support for rural Americans living with HIV/AIDS who don’t have access to the range of mental health services available in urban areas.

Older adults with HIV/AIDS face a unique situation: They not only must cope with the disease, but grapple with the mental, physical and social changes that come with aging, such as retirement and the loss of family and friends, Heckman noted.

“A lot is happening all at once, and it’s very difficult to cope with,” he said.

The telephone support group allowed older adults with HIV/AIDS to connect with people with similar experiences, said Lori Brown, a licensed social worker who moderated several of the phone sessions from the project’s home base in Athens, Ohio. Some older women, for example, discussed issues such as menopause, lack of a romantic partner and relationships with children with other women. In another support group, three participants who successfully underwent psychiatric treatment encouraged a fourth caller to seek professional counseling. And those who have lived with HIV/AIDS for many years offer hope to adults recently diagnosed with the disease, Brown noted.

“They often don’t have people in their own communities who have these same problems,” she said. “They find comfort in having someone to talk to.”

Participants in the phone intervention also sought to establish relationships outside of the group – exchanging cards, letters and e-mails and meeting in person, Heckman and Brown said.

“I was surprised how well they responded, never having met face to face,” Brown said. “I think it was because of the safety of the telephone.”

Heckman and his colleagues plan to continue the project using a larger, more geographically diverse sample of older adults with HIV/AIDS.

Collaborators on the study are Monica Silverthorn, the project coordinator and a licensed social worker, and Ohio University students Andrea Waltje, Melissa Meyers, David Cosio and Dana Mitchell.

Question: What is HIV and how does it differ from other viruses which infect human beings?
Answer: HIV stands for Human Immunodeficiency Virus. As the name suggests it only causes disease in humans, which leads to the depletion of white blood cells leading to lowering of immunity. Once the virus enters the body it lies dormant for many years and hence is known as a 'slow virus'. Most other viruses for example, those causing measles, mumps, chicken pox, etc., manifest the disease in 14-21 days after it enters the body. Hence the incubation period is short (2-3 weeks) whereas in HIV infection it is very long and runs into years.


Question: How does HIV attack the immune system?
Answer: Once HIV enters the body, it gets attached to a type of white blood cell called T lymphocyte (which is the T cell in the human body's protection against infections). The RNA (genetic material) of the virus then gets converted to DNA (genetic material) by an enzyme that the virus produces. This viral DNA then gets incorporated into the DNA of the human cell (T lymphocyte), and remains there for the lifetime of that cell. This infected cell now becomes a virus factory producing more viruses (HIV) which bud out of the cell, attack new T lymphocytes, and destroy them. Over a period of years, the T cell count of the infected person drops to a critical level and the individual develops many opportunistic infection and hence is then said to have AIDS.


Question: What is the difference between a person infected with HIV and one who has AIDS?
Answer: A person living with HIV (medically known as an HIV positive person) is one who has virus in his/her body. Such a person, remains infected and is presumed infective for the rest of his/her life. However, s/he will appear to be perfectly normal and healthy and asymptomatic for many years. An asymptomatic HIV infected person does not have Acquired Immunodeficiency Syndrome (AIDS). But when an HIV positive person's T lymphocytes (which are responsible for the immunity) count falls to 200 or less, s/he starts developing symptoms for eg. cough, fever, diarrhoea, skin lesions, etc. They are due to opportunistic infections (so called because they develop when the body's immunity becomes deficient) like TB, Thrush, Pneumonia, Cryptococcal meningitis, etc. All persons with AIDS are infected with HIV, but not all persons with HIV infection have AIDS. AIDS is only the end stage of this infection.

Question: How is HIV transmitted?
Answer: Anyone can become infected with HIV. It is transmitted only through unprotected penetrative sex (vaginal, anal, oral) with an infected partner, transfusion of infected blood and blood products, contaminat ed needles and syringes, and from an infected mother to her baby before, during delivery or through breast milk.



But since the sexual route accounts for almost 80 percent of infections, the prevalence is much higher in the sexually active age group of 15 years to 40 years. It is not who you are or where you are, but what you do that puts you at this risk of acquiring the HIV infection and eventually developing AIDS. Therefore, there are no "risk groups" but only "risk behaviours".


Question: How is HIV not transmitted?
Answer: HIV cannot spread by casual contact such as touching, holding hands, body contact in crowded public places, shaking hands, working or playing together, sharing food, vessels and clothes, eating food cooked by an infected person, light kissing, mosquito and other insect bites, swimming pools, and toilets.


Question: Do mosquitoes transmit HIV?
Answer: There is no evidence to show that mosquitoes transmit HIV. Epidemiologically, the incidence of HIV infection is the highest among the sexually active group of 15 years to 40 years. However, mosquitoes bite persons of all age groups and if they were a means of spreading HIV, the incidence of infection would be uniformly high and among all age groups. HIV does not survive or replicate inside the intestine of the mosquito, which is another reason to believe that mosquitoes cannot spread the HIV infection.


Question: Can HIV spread through kissing?
Answer: Kissing such as on the cheek or lightly on the lips carries no risk of transmitting HIV. In deep kissing there is a small risk because the saliva of an infected person contains few virus particles which by itself is not sufficient to cause the infection. But there could be bleeding gums or ulcers in the mouth and exchange of infected saliva mixed with blood during kissing could transmit the HIV.


Question: How long can the virus live outside the human body?
Answer: The Human Immunodeficiency Virus is fragile. Once the virus is outside the body in a dry form, it dies immediately. Even in a wet state, it does not live long when exposed to heat, detergents, or disinfectants. When stored in blood banks at 4°C, it can live for about 3 weeks (or longer), or till the white cell disintegrates, but in a frozen state it can survive for years.

Question: Can I get the HIV infection if I donate blood?
Answer: No. This is not possible as all materials used for collecting blood are sterile. In fact, persons who are healthy should come forward for voluntary blood donation.


Question: What is the risk of getting HIV by going to a dentist?
Answer: The risk of getting HIV from a dentist is low. However, there have been stray reports linking the infection with dentists. Wherever there is invasive procedures of skin or mucous membrane, universal precautions should be practiced.


Question: Is the breast milk of an HIV positive woman infective?
Answer: HIV is known to be present in the breast milk of an infected woman. Hence, there is a possibility of acquiring the infection via breast milk. However, in a country like India where infant mortality is very high, the advantages of breast feeding (prevention of other infections) outweigh the risk of HIV infection through breast milk. Formula feeding should be advocated on individual cases only after proper counselling.


Question: How would one know if a baby born to an HIV positive woman has the HIV infection?
Answer: Most children born to HIV positive mothers carry HIV antibodies from the mother in their blood. These take about fifteen months to disappear. Only after that will an HIV antibody test show whether the baby is, in fact, infected with the HIV, or not. In less developed countries, the chance of a baby born to an HIV infected mother being infected is about 40 percent. But today there are antiretroviral drugs available which can be given to the pregnant woman and babies to prevent the infection in the babies. As an alternative to pregnancy, women living with HIV could also be counselled to adopt a baby.


Question: How long does it take for an HIV infected person to develop symptoms?
Answer: This depends on the mode of the HIV transmission and the lifestyle of the HIV positive person. Majority of persons who are infected through blood transfusion develop symptoms on an average from 3 years to 5 years. With the other modes of transmission when the quantum of the virus is low, the person can remain healthy for 8 to 12 years or longer. If an HIV positive person improves his/her quality of life by adopting safer sex methods, has good nutrition, regular exercise, regular medical management, emotional support, does yoga and meditation, avoids stress and regularly treats other illnesses, continues to be active, and has an optimistic outlook, s/he is likely to live longer


Question: How does an HIV positive person progress to AIDS?
Answer: A few weeks after the virus enters the body, some people have flu-like symptoms such as fever, body ache, and headache, (every infected person may not experience these). These symptoms disappear after a while, and then there is a long phase of 3 years to 12 years which is asymptomatic. After that, when the immune system starts failing, AIDS sets in.
