HIV: QUICK FACTSIntroductionThe human immunodeficiency virus (HIV) is a subgroup of retrovirus (lentivirus) that causes HIV infection. After a period of time, this infection leads to what is called acquired immunodeficiency syndrome (AIDS).

Epidemiology

According to the Centers for Disease Control and Prevention (CDC), from 2010-2015, the estimated rate of HIV infection in all 50 US states decreased from 14.2 per 100,000 population in 2010 to 12.3 per 100,000 population in 2015. In 2015, 39,513 individuals were diagnosed with HIV infection. From 2010 to 2014, the annual number of new HIV infections decreased by 9%.

Virology HIV-1 and HIV-2 are retroviruses in the Retroviridae family, Lentivirus genus. They are enveloped, diploid, single-stranded RNA viruses with a DNA intermediate.Upon entry into the target cell, the viral RNA genome is converted into double-stranded DNA by an enzyme, reverse transcriptase that is transported along with the viral genome in the virus particle. The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded enzyme, integrase. HIV contains three retroviral genes, namely gag, pol, and env.

Gag gene: Encodes group-specific antigen; the inner structural proteins
Pol gene: Encodes polymerase; it also contains integrase and protease
Env gene: Encodes the viral envelope, the outer structural proteins responsible for cell-type specificity. Glycoprotein 120, the viral envelope protein, binds to the host CD4+molecule
Pathophysiology

HIV infects vital cells in the human immune system, such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells and leads to cellular immune deficiency. This results in the development of opportunistic infections and neoplastic processes.

Mode of Transmission
Sexual intercourse: Unprotected sexual intercourse; especially receptive anal intercourse and different sexual partnersContact with or transfer of blood, pre-ejaculate, semen, and vaginal fluids infected with the virus.Spread from an infected mother to her infant through breast milk. An HIV-positive mother can transmit HIV to her baby both during pregnancy and childbirth due to exposure to her blood or vaginal fluid.

Signs and Symptoms There are 3 categories of infection 

Category A: Asymptomatic HIV infection without a history of symptoms or AIDS-defining conditions
Category B: HIV infection with symptoms that are directly attributable to HIV infection
Category C: HIV infection with AIDS-defining opportunistic infections
Investigation

A high-sensitivity enzyme-linked immunosorbent assay (ELISA) should be used for screening.

Management

Start with antiretroviral therapy (ART) in all HIV-infected adults ready to start therapy. 
CD4 count is no longer a criterion for starting the therapy.
Use of nucleoside reverse transcriptase inhibitors and protease inhibitors.
For refractory cases, during the failing treatment regimen and before switching therapy, use rapid confirmation, perform resistance testing and reevaluate.

HIV - Quick Facts Need To Know!

HIV or the human immunodeficiency virus is a retroviral agent that causes the immune system of the body to weaken and lead to cause the acquired immune deficiency syndrome (AIDS). It is now treatable. Research is being conducted all over the world to formulate a targeted drug therapy for combating this life-threatening disease. No vaccine is available, which renders the world population highly susceptible to contract the infection.

HIV infection spreads from an infected person through contact with certain bodily fluids like blood and semen. Spread from one human being to another is called as transmission of HIV. Mother to child transmission, i.e. perinatal transmission is also common. Healthcare and hospital staff are at a great risk of occupational transmission. Other causes of transmission include sharing intravenous drug equipment, needle prick injury, organ transplantation and artificial insemination. Since vaccination and targeted drug therapy for remission are not available, prevention strategies play an important role in curbing the spread of infection.

A three-level prevention strategy is implemented for HIV infection.

Primary prevention- Activities that focus on prevention of uninfected people being infected.
Secondary prevention- Aimed at the provision of proper health care and behavioral facilities for HIV infected people like lifestyle changes, welfare rights advice, anti-discrimination measures.
Tertiary prevention- Aimed at minimizing the symptoms of an infected person; includes the provision of prophylactic drugs and complementary therapies.
The risk avoidance approach for transmission of HIV infection includes certain measures like practicing mutual monogamy & delayed sexual activity in the young population. Safe and appropriate use of syringes and needles is advised. Unnecessary blood transfusions should be completely avoided. Routine screening of HIV antibody should be done.

Risk reduction approach propagates the mandatory use of condoms during sexual intercourse. Sexually transmitted diseases should be treated to avoid the risk of transmitting infection. Sterile syringes should be used. If blood transfusion is necessary, then blood transfused should be evaluated well to meet the quality standards.

If HIV infection is suspected, anti-retroviral drug therapy should be started.
The only universally approved method of HIV transmission during sexual activity is the use of condoms.
Pharmaceutical methods for prevention and treatment include antibiotic drug therapy for sexually transmitted diseases, anti-retroviral drugs for infected individuals, pre and post-exposure prophylaxis and use of low space dead syringes.
Pre-exposure prophylaxis is advised for people who are at a higher than average risk of contracting the infection.
Drug therapy consisting of a combination of Tenofovir and Emtricitabine is prescribed, one per day.
Visit the physician at regular intervals and routine screening is done. Post-exposure prophylaxis is considered to be effective if the treatment is started within an hour of exposure, to effectively reduce the risk of seroconversion. A drug combination of Emtricitabine, Tenofovir and Raltegravir is given.
Social initiatives are undertaken to spread awareness and educate people regarding AIDS. Behavioral change and acceptance of social message is necessary to benefit from the social initiatives. Sex education, LGBT sex education and awareness, safe injection use programs, needle exchange programs, safe sex practice education are some social strategies implemented.
Prevention of transmission of HIV from mothers to children involves anti-retroviral drug therapy during pregnancy and post birth in the newborn child. Breastfeeding is avoided and bottle feeding is advised.

HIV Transmission - How Can It Be Prevented?

Acquired Immune Deficiency Syndrome(AIDS) is caused by a virus called Human Immunodeficiency virus (HIV). It should be remembered that it is not necessary that a person having HIV is suffering from AIDS or will inevitably result in it. The illness damages the immune system of the person and makes them more vulnerable to diseases and infections. As the syndrome progresses, opportunistic infections attack the patient, ultimately causing their death.

What are the causes of AIDS?
The virus is spread by person-to-person contact like:
1. Through sexual contact.
2. By sharing the same needle or through blood transfusion.
3. The disease can be spread from mother to the newborn child.

What are the symptoms of AIDS?
1. You may have a high fever or suffer from constant diarrhea which may last for weeks.
2. Red rashes may appear on your skin.
3. You may feel weak and tired all the time.
4. You may have excessive sweating, particularly at night.
5. Your muscles and joints may ache.
6. Your swollen glands don t heal for weeks.

What are the complications related to AIDS?
During the last stage of infection, there is a high risk of having life-threatening diseases.These include:
1. Infections to the nervous system like meningitis, peripheral neuropathy.
2. Inflammation in the lower end of the esophagus.
3. Cancers like cervical cancer, neck cancer, and lymphomas.
4. Tuberculosis.

Can AIDS be treated with homeopathy?
Homeopathic treatment can be of a great help for such patients. It can boost up not only physical health but mental health too. It can combat opportunistic infections very effectively by boosting up the immunity of the patient. There are marvellous results with homeopathic medicines tried in Africa (an epidemic zone for AIDS). Many patients of AIDS are still waiting to die after using homeopathy and their quality of life has improved drastically. Homeopathy works by modulating the immunity which is an important factor in AIDS patient. Some of the homeopathy medicine used to treat symptoms of AIDS are:
1. Syphilinum
2. Arsenic iodum
3. Sulphur
4. Silica,
5. Tuberculinum
6. Kali carbonicum
7. Calcaria iodum
8. Bacillinum
9. Arsenica Album
10. Phosphorus
These medications can be used in conjuction with ART or antiretroviral therapy along with other treatments and has been shown to be very effective in alleviating some of the commonly encountered symptoms of AIDS related complications. But utmost care must ensured and these medicines should not be taken without consulting a homeopathic doctor.

HIV / AIDS - Can Homeopathy Medicines Helps in Treating it

For nearly 30 years, HIV (human immunodeficiency virus) and AIDS (acquired immunodeficiency syndrome) have been shrouded in myths and misconceptions. In some cases, these mistaken ideas have prompted the very behavior that cause more people to become HIV positive. Here are the top five myths about HIV, along with the facts to dispute them.

Myth No. 1: I can get HIV by being around people who are HIV-positive.

The evidence shows that HIV is non communicable and does not spread through touch, tears, sweat or saliva. You cannot catch HIV by:

    Breathing the same air as someone who is HIV-positive
    Touching a toilet seat or doorknob handle after an HIV-positive person
    Drinking from a water fountain
    Hugging, kissing, or shaking hands with someone who is HIV-positive
    Sharing eating utensils with an HIV-positive person
    Using exercise equipment at a gym

You can get it from infected blood, semen, vaginal fluid, or mother's milk.

Myth No. 2: I can get HIV from mosquitoes.

Because HIV is spread through blood, people have worried that biting or bloodsucking insects might spread HIV. Several studies, however, show no evidence to support this, even in areas with lots of mosquitoes and cases of HIV. When insects bite, they do not inject the blood of the person or animal they have last bitten. Also, HIV lives for only a short time inside an insect.

Myth No. 3: I'm HIV positive, my life is over.

In the early years of the disease epidemic, the death rate from AIDS was extremely high. But today, antiretroviral drugs allow HIV positive people and even those with AIDS to live much longer, normal and productive lives.

Myth No. 4: My partner and I are both HIV positive there's no reason for us to practice safer sex.

Practising safer sex, wearing condoms or using dental dams can protect you both from becoming exposed to other (potentially drug resistant) strains of HIV.

Myth No. 5: You can't get HIV from oral sex.

It's true that oral sex is less risky than some other types of sex. But you can get HIV by having oral sex with either a man or a woman who is HIV positive. Always use a latex barrier during oral sex.

Top 5 Myths & Misconceptions About HIV & AIDS!

HIV infection and AIDS (commonly referred to as HIV/AIDS) are caused by the Human Immunodeficiency Virus (HIV). HIV is transmitted sexually and through exchange of body fluids, such as blood. The HIV attacks our defense system (immune system) giving opportunity to many illnesses to attack the body. These infections (called opportunistic infections) range from common cold and diarrhea to life-threatening illnesses including uncommon pneumonias and cancers. The type, range and intensity of opportunistic infections vary with the severity of the HIV infection and the extent to which our immunity is compromised. 

AIDS is the last stage disorder of the HIV infection. Though there is no complete cure for the HIV-infection till date - despite thousands of scientists across the world working on it, spending countless hours of research involving billions of dollars - there has been tremendous progress in medicare improving the quality of life of the HIV-infected, in extending their life-span to almost normal levels and in preventing mother-child transmission. 

The key factors in extending the life-span, and in keeping good immunity and good health are 

balanced and nutritious diet

regular physical exercise

correct, consistent and lifelong use of the prescribed medicines

periodic medical checkups

staying psychologically positive and strong

good family support and

good lifestyle habits.

The last one involves maintaining good personal hygiene, avoiding smoking (active as well as passive), alcohol, recreational drugs, unhygienic and disease-prone environments and sedentary life style. Those who follow these will guidelines certainly have better prognoses. 

Diet:

A nutritious diet is of utmost importance to the HIV-infected, as adequate nutrition contributes to the development of the immune system, prevents malnutrition and wasting, achieves and maintains optimal body weight and strength, enhances the body s ability to fight opportunistic infections, helps delay the progression of HIV, improves the effectiveness of drug treatments, and improves the quality of life. 

Ensure that the food contains adequate macronutrients, that is, carbohydrates, proteins and fat, otherwise the patient may end up with - protein-energy malnutrition, manifesting itself in the weight loss and wasting that is typical of AIDS patients.

As per WHO, an HIV-infected person has additional nutrient requirements: 10-15 percent additional energy intake and 50 to 100 percent increase in protein intake as compared to a non HIV-infected person.

Consuming micronutrients (especially Vitamins A, B6 and B12, iron and zinc) is important for building a strong immune system and fighting infections.

Try and maintain a daily diet containing rice/roti, vegetables, legumes, and fruits which provide you energy and micronutrients. Choose foods that are low in saturated fat, trans fat, and cholesterol.

Eat at least two servings of fish each week. Oily fish, which contain omega-3 fatty acids, are best. If you cannot eat fish, you can also get omega-3 fats from omega-3 eggs, walnuts, flax seeds.

Better avoid fast foods.

Living with HIV/AIDS: Diet, Nutrition, and Food Safety

HIV or Human Immunodeficiency Virus is a type of immune disorder which attacks the immune system of the body and slowly destroys it overtime. The HIV virus targets the immune system and makes the body susceptible to other diseases. HIV infection can progress to AIDS although it may take up to 10 or 12 years to fully go into the last stage.

Risks and Causes
HIV is a communicable disease which spreads through only the following methods

    It can spread from one person to another by means of unprotected sexual intercourse due to the exchange of bodily fluids.
    The virus spreads if you share drug needles with someone who is already contaminated with HIV virus. It can also occur due to improperly trained medical staff that may reuse syringes although this is very uncommon.
    The HIV virus transmits from the mother to the child during pregnancy through the placenta.
    Any exchange of blood in significant amounts such as blood transfusion from a contaminated patient will result in infection as well although this is very rare.

Any other form of contracting the disease such as through kissing or food is a untrue and only propagates due to ignorance.

Symptoms
The initial symptoms of HIV infection are noticed after a few weeks although it can take a few months to come up as well. The initial symptoms may include
1. Severe headache along with intense pain in the muscles and the joints of the body.
2. Frequent appearances of rashes
3. inflation of the lymph nodes
4. Itchy skin
5. Disorders which stay for sustained periods such as an upset stomach or a cold.

The early symptoms disappear within 2 to 3 weeks without any treatment. The later symptoms might appear after few years (sometimes up to or more than a decade), which will stay. This is usually the time HIV is diagnosed. The symptoms now may also include
1. severe muscle fatigue
2. severe loss in body weight,
3. High fever and recurrent instances of sweating at the night time.
HIV is suspected if the later symptoms tend to last for a long time without any other diagnosable cause.

Treatment
HIV can be treated by means of antiretroviral therapy which reduces the rate at which the virus multiplies. However, there is no cure for HIV as of yet.
Prevention
In order to prevent yourself from getting HIV, you should adopt the following precautionary measures:
1. You should use protection every time when engaging in sexual intercourse and if you are unsure of your partner s HIV status.
2. You should use new blades in barbershops for shaving purposes in order to prevent yourself from HIV as well
3. If you are diagnosed with HIV/AIDS while you are pregnant, to prevent spreading it to your unborn baby, you might immediately need undergo a medical check-up and follow the doctor s advice.
4. Ensure that disposable syringes are used whenever they are being use for medical tests or treatments.
