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!

What is Monogamous Relationship?

You (who have been tested for STD/STIs and don't have any) are having sex with only one partner (who also has been tested for STD/STIs and doesn't have any) who only has sex with you. And you both keep it that way! 

Stated another way, you are both STD/STI free and only have sex with each other. People of any sexual orientation can engage in monogamous relationships. The only thing implied by the term monogamy is that the relationship consists of two people who are romantically and/or sexually exclusive. Theoretically, outside of abstinence, this is really the safest type of "safer sex" that you can have. 

Celebrated on 1st December of each year, World AIDS Day, aims to spread awareness about HIV / AIDs. It is an STD wherein, HIV stands for human immunodeficiency infection and AIDS stands for acquired immune deficiency syndrome. The disease hinders the immune system in keeping up our body s security against sickness. HIV causes individuals to end up wiped out with infections that regularly would not affect them and HIV leads to AIDS.

Understanding the Symptoms:

HIV has few or no signs or symptoms for up to ten years or more before side effects of AIDS tends to manifest. There is no cure for HIV/AIDS, yet treatment is accessible. A few people have HIV symptoms not long after being infected. These include:

There are a few phases of HIV illness. The primary HIV side effects may include swollen glands in the throat, armpit, or crotch.
Other early HIV symptoms incorporate slight fever, headaches, exhaustion, and muscle throbs.
These symptoms may keep on going for just a couple of weeks. At that point, there are typically no HIV indications for a long time. That is the reason it can be difficult to know whether or not a person is suffering from HIV.
The symptoms of AIDS show up in the most advanced phase of the HIV disease. These are as follows:

Along with a severely damaged immune system, a person with AIDS may likewise have thrush. A thrush is a thick, whitish covering on the tongue that is brought about by a yeast infection and now and then joined by a sore throat.
Serious or repetitive vaginal yeast infection.
Pelvic inflammatory illness.
Serious and frequent infections.
Unexplained fatigue that might be followed by headaches, dizziness.
Loss of more than ten pounds of weight that is not because of physical exercise or consuming fewer calories.
Risk Factors: There are a lot of ways in which you can get the infection. HIV is transmitted through blood, semen, vaginal fluids and breast milk. The most well-known ways in which HIV is spread, are:

Having sexual intercourse without a condom with somebody who has HIV/AIDS.
Using needles or syringes that have been used by someone who has HIV/AIDS.
Being punctured with a needle or surgical instrument that has been contaminated with HIV.
Getting HIV blood, semen or vaginal discharge into open injuries or wounds.
Babies born to women with HIV/AIDS can get HIV from their mothers during birth or from breastfeeding.
There are numerous ways in which you can protect yourself from HIV. These are as follows:

The most secure way is to limit the number of sexual partners you take on.
Try to have safer sex and always use protection.
Get your partners tested for HIV.
HIV tests are a typical piece of social insurance.
In case that you think you may have been infected by HIV, talk to a specialist or a doctor about testing. Discussing what risks you might have taken can help you choose whether testing is ideal for you.

This World AIDS Day - Let's Spread the Awareness About HIV/AIDS

A couple of decades ago, medical professionals believed that a lot of females could not climax at all. There are a number of reasons for this. It is easy for the male to know when he has achieved an orgasm, which usually happens with ejaculation, which is quite evident. For the females, on the other hand, it is not so evident. It is a perceived feeling and while the media showcase it in a particular way, reality is far moved from it.
There are various reasons why it is very difficult to pin this down. Orgasms are not just an elusive feeling for the woman, it is an elusive topic for the medical professionals too. Read on to know some of the common causes (more beliefs or notions) about this and some simple but effective ways of managing this.
- Private topic: Girls are very shy compared to boys and both their exposure to sex education and discussion about this is limited compared to boys. We might tend to think of it as common in India alone, but this is true across a vast number of countries. We are not alone! This shyness continues into their later years too, and unless transformed by the partner, it may continue to be a topic that is shunned.
- Purpose: Sex is more deemed as a form of procreation rather than for sex. Therefore, while sex is necessary for conception, orgasm is not. This is one more reason (strange but true) that orgasm is very elusive for a woman.
- Psychological factors: It could be guilt from past relationships or fear of past abuse. It could be fear of losing control or fear of coming across as vulnerable. For any of these reasons, women can have difficulties climaxing during the act.
In men, the causes are more defined and physical in nature and include erectile dysfunction, premature ejaculation, retrograde ejaculation, and delayed ejaculation.
Whatever the cause of the problem, the first step in coping up with the issue is to acknowledge the issue. Being a private topic, this is not something that is going to draw the person towards medical help. However, this needs to be discussed frankly with the partner or with the doctor. Getting the partner involved removes a lot of psychological barriers (guilt, fear, anxiety, etc.) This would result in natural ironing out of issues, improving the performance of both the people involved.
If that does not happen, seeking professional help, be it medical help to correct physical issues or counselling, is the next suggestion. A frank discussion will do wonders, and what was once elusive can be well within your reach.

The Elusive Orgasm - Causes and Coping!

With changing times the nature and effects of virus and bacteria are also changing and due to this, one of the biggest risks of unprotected sex is catching a sexually transmitted disease or STD. An STD can be contacted by any form of intercourse including oral, vaginal and anal sex. STDs are serious diseases that should not be ignored and require treatment and medication. Some common STDs are:
1. Chlamydia
2. Hepatitis B
3. Genital Herpes
4. Syphilis and
5. Gonorrhea 

The only way to protect yourself from an STD is to abstain from unprotected sex and always use a condom. Sometimes STD infections have no symptoms and can remain dormant for years, hence it is essential to get yourself regularly treated for STDs if you have more than one sexual partner. On the other hand some STDs have visible symptoms such as:

Skin rash
A rash in the genital area is most often a sign of STDs. This can be in the form of bumps, sores or warts. It may or may not be accompanied by itchiness. A rash caused by a STD usually results in redness and inflammation. Herpes sores may subside within a week or so but just because the rash is gone does not mean the infection has been treated. Hence even if the rash disappears before your doctor's visit, ensure you mention it. 

Painful urination
A burning sensation or pain while urinating is a symptom for a number of STDs. There may also be a change in the colour of urine. Some STDs associated with painful urination as Chlamydia, gonorrhea and trichomoniasis. However, this may also be triggered by kidney stones or a urinary tract infection. 

Painful intercourse
Pain during intercourse is one of the most overlooked symptoms of a sexually transmitted disease. While a little pain may be normal, any sudden increase in pain or new type of pain should not be ignored. This should be kept in mind especially when having intercourse with a new partner or if there is a change in sexual habits. When it comes to men's sexual health, pain at the time of ejaculation can be a symptom of a STD.

Abnormal discharge
Abnormal discharge from the vagina or penis can be a symptom of a number of infections not all of which are STDs. Strangely coloured and odorous vaginal discharge can be a symptom of yeast infections or a Sexually transmitted disease like trichomoniasis or gonorrhea. Bleeding in between periods can also be a symptom of a STD.  Abnormal discharge from the penis can be a sign of Chlamydia, gonorrhea or trichomoniasis.

Learn the Signs and Symptoms of STDs

The human immunodeficiency virus or hiv is a virus which causes hiv infection and leads to" acquired immunodeficiency syndrome" or aids. Hiv is transmitted by different means and ways.


Unprotected sex is a primary mode of transmission of the hiv virus from an infected person to a healthy person. Unprotected sex refers to having sexual intercourse without using a condom or any other mode of protection. It leads to hiv transmission along with other sexually transmitted infections.


How does hiv occur from unprotected sex?
While having sex without protection, the hiv present in the body fluids such as blood, sperm, vaginal fluid, pre-cum or anal mucus of an hiv infected patient can pass on to the body of his/her partner. The transmission occurs through the membranes of the penis in men, vagina in women, the rectum and also through mouth and throat. It is more likely for an hiv patient to pass on the virus during the first few months after getting infected. This is because the virus spreads over body fluids during this stage.


Which types of sex are more risky?
Hiv is transmitted the most by having vaginal or anal sex. Anal sex accounts for being the riskiest because the lining present in the anus is much more delicate than the vaginal lining. It is prone to more damage, easily. There are two types of anal sex: receptive anal sex and insertive anal sex. Receptive anal sex is more risky.


Hiv can also be acquired from oral sex. This can happen in case the person giving oral sex has ulcers in the mouth, sore and bleeding gums. In case the person receiving the oral sex is already infected, the other person gets hiv.


A person who has sex with multiple partners regularly is at a high risk of getting hiv because of unprotected sex.


Prevention
Getting hiv from unprotected sex can be avoided if you use these precautions:


- condoms
Condoms offer the precaution against hiv infection from anal or vaginal sex. They should be used by men before any kind of sexual contact to restrict the passing of semen or fluid, which may be infected by hiv.


- lubricants
Sex is made easier by using lubricants and reduces the risk of tearing in the vagina or anus due to friction. The risk of a condom breaking is reduced using lubricants.


- dental dams
This is another precautionary device, which is a small sheet of plastic. It has to be placed to cover the mouth of the vagina or anus and reduce the risk of hiv transmission.
Unprotected sex is the primary cause of hiv and people who do not take precautions before sex are likely to be infected by hiv.

HIV and Sex

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.
