Human Immunodeficiency Virus (HIV) is a retrovirus. It was first discovered in early 1980s. It affects a type of white blood cell (T Cell). Once this virus enters inside the body it completely cover the T Cell and start making a number of copies of itself. It fails the immune system of the body, which causes Acquired Immunodeficiency Syndrome (AIDS). Currently, there is no vaccine available to prevent HIV infection.

HIV is present 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, or eyes (the mucus membranes), or with a break in the skin, such as from a cut or puncture by a needle.

What are the early symptoms of HIV infection?

Many people do not develop any symptoms when they first become infected with HIV. Some people, however, get a flu-like illness within three to six weeks after exposure to the virus. This illness, called Acute HIV Syndrome, may include fever, headache, tiredness, nausea, diarrhoea and enlarged lymph nodes (organs of the immune system that can be felt in the neck, armpits and groin). These symptoms usually disappear within a week to a month and are often mistaken for another viral infection.

Neurological and psychiatric involvement: HIV infection may lead to a variety of neuropsychiatric sequelae, either by infection of the now susceptible nervous system by organisms, or as a direct consequence of the illness itself.

Toxoplasmosis is a disease caused by the single-celled parasite called Toxoplasma gondii; it usually infects the brain causing toxoplasma encephalitis but it can infect and cause disease in the eyes and lungs

Risk Factors

Have unprotected sex with multiple partners. You’re at risk whether you’re heterosexual, homosexual or bisexual. Unprotected sex means having sex without using a new latex or polyurethane condom every time.

Have unprotected sex with someone who is HIV-positive.

Have another sexually transmitted disease, such as syphilis, herpes, chlamydia, gonorrhea or bacterial vaginosis.

Low Status of Women: Infection rates have been on the increase among women and infants in some states. As in many other countries, unequal power relations and the low status of women, as expressed by limited access to human, financial, and economic assets, weakens the ability of women to protect themselves and negotiate safer sex, thereby increasing vulnerability.

Many of these risk factors are behavioral in nature. In other words, by avoiding high-risk behaviors, you can reduce or virtually eliminate your risk of HIV/AIDS infection. Learn the risk factors. If necessary, change your behavior.

First of all, you should know that HIV and AIDS are transmitted through direct contact with infected bodily fluids. There are several common ways that people are infected:

• Sexual contact through vaginal or anal sex
• Sharing needles with an infected individual. Rarely, this can include tattoos and piercings
• Blood transfusions or accidental exposure to infected blood
• Mother to child transmission during pregnancy or during birth. Breast feeding, in some cases, can also lead to HIV infection

How can it be prevented?

The most important precautions to take are to make sure that you always use a new, sterile needle for any injection that you take, and to always use a condom during sex unless both you and your partner have had an HIV test. The contraceptive pill, diaphragms and spermicidal jelly cannot prevent infection during sex – only condoms are an effective preventative.

What are the symptoms?

Unfortunately, HIV and AIDS do not present any clear symptoms. Approximately 4 weeks after infection, most people will suffer a fever, glandular swelling, rashes, a sore throat and muscle aches. Since these symptoms are so general, they are frequently mistaken or misdiagnosed. The only way to be certain is to take an HIV or AIDS test.

What are the treatments?

There is currently no cure or vaccine for HIV or AIDS. However, there are various courses of retroviral drugs that can help to manage the symptoms and greatly increase the quality and length of life. Early diagnosis is critical, which is why HIV tests are so important for anyone who thinks they may have been exposed to the virus.

How do I get an HIV test?

There are numerous sexual health clinics around the US that offer confidential HIV tests. Most people choose to purchase them privately rather than through their insurance for the sake of privacy.

The first HIV test that is usually administered is the HIV-1 test. This is a blood test that checks for the antibodies that the body produces to fight the HIV infection. However, it can only be taken six weeks or more after exposure, as it takes time for the body to generate these antibodies. Another HIV test, the HIV PCR, can detect the virus 4-11 days after exposure. If either of these initial tests gives a positive result, follow tests are required to confirm it (the HIV-1 test can occasionally give false positive results, as it is very sensitive.)

How often should I have an HIV test?

Comprehensive STD screening, including an HIV test, is recommended once a year for all sexually active adults who have three or more sexual partners in that year. An HIV test is also recommended if you intend to start having unprotected sex with a partner, and, due to the risk of transmission to a child, is usually part of a standard health check up at the start of a pregnancy.
