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!

An STD or sexually transmitted disease is usually an infection which spreads from one person to another during sexual contact. Some STDs can also be transferred through touch, since they spread by skin contact. People hardly like to talk or discuss about STDs, but it is very important to rule out the possibilities of STD. Whether one likes it or not, if STD testing is ignored, then it can lead to long term consequences.

Why STD Testing is Important

Often STDs have no signs and symptoms, and the only way to know that are you suffering from an STD is to get tested for it. So it is a good idea to get yourself tested, as you never know if you might have STD even though you don't show symptoms. Also, when STDs are diagnosed, most of them can be cured.

Consequences of Not Getting Tested

If one has STD and is not getting tested for the same, then it could lead to health problems which can cause permanent damages or might prove to be fatal. Some of the problems are:

1. Undiagnosed and untreated STDs can lead to damaged reproductive system, leading to sterile men and women. 
2. Chlamydia, if untreated can lead to epididymitis and shrinkage of testicles and infertility in men. It also leads to pelvic inflammatory disease. But good news is, it can be treated easily.
3. Syphillis can make a person blind and deaf, and can also be passed on to babies. 
4. Gonorrhea, which can also be treated easily with antibiotics, can lead to infertility or death if untreated. 
5. Even HIV/AIDS if diagnosed in early stages can enable the patient to lead a normal life and does not mean only death, contrary to conventional perceptions.  

Symptoms of STD

While, gonorrhea, chlamydia and human papilloma virus (HPV) have no symptoms, the common symptoms of STDs might vary. 

1. In women, the common symptoms are pain and burning sensation during urination, blood in vaginal discharge as also abnormal vaginal discharge, abdominal pain, blisters, warts, and swollen glands. 
2. Men often experience inflammation of the testicles, prostate, sores, fever, urethral discharge and pain during urination.

If these symptoms are observed, it is vital to get tested for STDs. Also the best way to protect your partner is not to practice unsafe sex and to refrain from the same until diagnosed and treatment is complete.
 
Getting yourself tested for STD is also beneficial, as it can prevent against complications like cancers and infertility. The standard STD panel of tests consists of Herpes IgG antibody and HIV antibody blood tests, along with a blood test for syphilis antibody and DNA urine test for gonorrhea and Chlamydia.

The Dangers of Putting Off STD Testing

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.

HIV / AIDS - Things You Should Remember About It

Sexually Transmitted Diseases (STDs) are infections that you can get from having sex with someone who already has the infection. The causes of STDs are bacteria, parasites, and viruses. These infections often do not cause any symptoms, and can still be passed unknowingly from the infected partner to the other. However, some common symptoms include genital itching, lesions, flu / fever like symptoms and feeling pain / pressure in the lower part of the stomach.

There are many kinds of STDs including Chlamydia, gonorrhea, genital herpes, syphilis and HIV.

The important thing to understand and know is that these STDs can be prevented.

3 ways of preventing STDS are:

1. Precautions before having sex

There are some things you can do to reduce your risk of contracting STDs before having sex. This include:

  Limiting the number of sexual partners
  Talking honestly with partners about your sexual history
  Getting tested, along with your partner, before having sex
  Getting timely vaccination against HPV and HBV

If you have been diagnosed with an STD you should tell your partner about it and also explicitly ask your partner if they have had an STD.

2. Practice safe sex

Use a latex condom every time you have sex and use a water-based lubricant. If your sex life involves intercourse, anal or vaginal, make up your mind to never have sex without a condom. If you or your partner is at a high risk of STDs, be consistent about barrier use during oral sex as well. Avoid sharing towels or underclothing to reduce the risk of an STD. Check the expiration date of the condom and make sure that it has an air bubble, which shows it has not been punctured. Dispose the condom properly and never reuse it.

3. Don't drink Alcohol or use drugs before having sex

It's impossible to make responsible choices about your sex life under the influence of drugs or alcohol. When you are under the influence of any one of them, you are not in your mind and are likelier to choose a partner you wouldn't have picked otherwise. In that case, you may be at a higher risk of contracting an STD. Also, if you are on birth control pills and you vomit, the pills could lose some effectiveness.



3 Ways You Can Prevent STDs (Sexually Transmitted Diseases)

Don't Panic !

Having unprotected sex isn't the smartest move a person can make, but it isn't necessarily the end of the world, so follow the advice below and you should be fine.

We Had Unprotected Sex And...I Think I'm Pregnant

Finding out you're pregnant can be the happiest or the scariest day of your life.

Don't wait around and bury your head in the sand saying 'it won't happen to me' and 'I'll be fine' you might not be, and then you'll find yourself in a much more difficult situation than if you'd faced the situation head on and quickly.

If the intercourse happened less than 72 hours ago, emergency contraception, the morning-after pill, can be taken as a precaution against you becoming pregnant. However, note that the sooner you take the emergency contraceptive pill, the higher its efficiency is.

We Had Unprotected Sex And...I Think I Have an STI

Check for any unusual symptoms around your genitals (vagina or penis), such as:

Pain when you urinate
Itching
An unusual or smelly discharge
Sores
Unexplained bleeding
If any consult your healthcare provider immediately

Not all STIs have visible symptoms so even if you think you're fine, after having unprotected sex, get tested!

Go For Sexually Transmitted Disease Profile Including HIV ( 1ST Month HIV RNA, 3RD MONTH HIV ELISA), HSV 1 and 2, HbsAg, HCV, Urine Routine, VDRL, etc.

We Had Unprotected Sex And...I Think I May Get HIV

Take Post Exposure Prophylactic Drugs (Anti - HIV) as soon as possible. It works when started within 72 hours and must be continued for 1 month to prevent HIV.
