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?

In most diseases, early detection of the disease is the key to control the symptoms, cure, reduce progression and improve prognosis. This holds true for sexually transmitted diseases too. As soon as there is a mild degree of suspicious of having contracted a sexually transmitted disease, it is advisable to go for a test. Most of the STDs can develop into serious complications over a period of time, ranging from infertility to even death.

Complications: Why early diagnosis is important: When left undiagnosed and untreated, most STDs progress to cause severe damage from sterility to cancer to even death. Listed below are some complications associated with each of the common STDs.

Chlamydia: If left untreated, can lead to epididymitis and testicles shrinking and infertility in males. This is a condition where there is pus formation in the scrotum. In women, it can lead to pelvic inflammatory disease which is deep-seated and unable to cure completely. This brings with it symptoms ranging from abdominal pain to uterine infections to sterility.
Syphillis: Undiagnosed syphilis can lead to blindness and deafness. It can also be passed onto the newborn and lead to severe disabilities.
Gonorrhea: If diagnosed early, it can be cured completely with antibiotics. However, if left untreated, it can lead to infertility.
HIV/AIDS: Early diagnosis can help in curtailing the disease. If detected late, then the damage is quite extensive and treatment is both expensive and cannot help restore a lot of functions. 
Symptoms of Sexually transmitted diseases: If there is a doubt of having contracted an STD, then it is very important to get tested for the same. Some of the most common symptoms are listed below.

Women: The most common symptoms in women including painful urination, burning sensation, abnormal vaginal discharge (sometimes bleeding), warts, and abdominal pain.
Men: Testicular pain, urethral pain, painful urination, pain and inflammation in the prostate, sores, fever, and abdominal pain.
Prevention: Always practice safe sexual practices. When in doubt, refrain from sex until diagnosis and treatment is complete.

Testing for STDs: Some of the standard tests include:

1. Herpes- HSV I & II - 
2. Testing HIV-- Kits and ELISA available for testing 
3. Blood test for syphilis antibodies 
4. Chlamydia and Gonorrhoea - from urine as well as swabs for culture
It is understandable that getting tested for STDs is an embarrassing situation. However, there are options available where anonymity can be maintained when getting tested for STDs. This is a wise choice to make as the risk is not just for the person affected but for the partner and in some cases even for the fetus. Early testing can help prevent complications like infertility and cancer.

STD Testing - Why You Should Never Delay?

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.



What If You Have Unprotected Sex?

Any kind of dysfunction points to the issues experienced during any stage of the cycle of physical issue that prevents the participants from experiencing any kind of satisfaction from the intimate activities.

Sexual Problems - Things That Can Lead to It

Sadly, there is no known cure for hiv. However, it can be controlled through medication. Hiv or the human immunodeficiency virus attacks the body's immune system and over time leaves it vulnerable to a number of other diseases. In its most advanced stages, it can lead to aids. Hence, it is essential to control this virus in its early stages.

Hiv treatment is known as antiretroviral therapy or art. This involves taking a series of hiv medicines on a daily basis. Art can help hiv patients live a longer, healthier life and can also reduce the risk of hiv transmission.

The first step towards getting treated for hiv is to get tested. This can be easily done at your nearest health center and the results will be kept confidential. With hiv prevention is better than cure and hence, if you have more than one sexual partner, you must insist on them getting tested as well.

As soon as you test positive for the virus, start the treatment. Do not wait till you start feeling sick. Art can be taken by anyone at any stage of the condition. If you are pregnant, breast feeding or have been diagnosed with early hiv infection, this is all the more important.

Hiv medication works by preventing the hiv cells from multiplying and thus reduces the amount of hiv cells in the body. A low level of hiv cells gives the immune system a chance to recover and strengthen itself. A lowered hiv count also reduces chances of transferring the virus to another person.

Art involves following a regimen of a number of medicines. There are 25 hiv medicines that can be grouped under six drug classes depending on how they affect hiv cells. These include:

1. Nucleoside reverse transcriptase inhibitors
2. Non-nucleoside reverse transcriptase inhibitors
3. Protease inhibitors
4. Fusion and entry inhibitors
5. Pharmacokinetic enhancers and
6. Integrase strand transfer inhibitors

Usually, a person is prescribed 3-4 hiv medicines from a minimum of 2 drug classes. A number of factors go into deciding what form of hiv treatment is most suitable to a patient. This includes the person's individual needs, symptoms presented, potential drug interactions and possible side effects. Convenience of following the regimen and costs are also taken into account while prescribing a form of treatment to a hiv patient.

Once treatment is started, art can be proven to be effective within 3-6 months by lowering the number of hiv cells in the body.
