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

Oral sex is a form of sexual activity, which involves the arousal of one's genitalia by his/her partner using the mouth (tongue, lips and throat). It is also called Cunnilingus (performed on a female) and fellatio (performed on a male). It is done before intercourse and during foreplay for sexual arousal. It is safe as compared to vaginal or anal sex, the rate of getting a sexually transmitted disease or HIV is comparatively lower. 

Oral sex can spice up your life and can also make your partner reach orgasm. It is also a safe way of getting sexual pleasure without getting pregnant. But necessary precautions must be taken in order to have safe oral sex.

Some of these necessary precautions are:

1. You can get throat cancer from oral sex: Human papillomavirus (HPV) is a cancerous virus found in the body of infected people. This virus can be transmitted to the person with whom you are engaging in oral sex. Studies show that people who engage with more than 6 sexual partners at once are more prone to get oral cancer. It is advisable to get your partner tested for HPV virus before engaging in oral sex.

2. Oral sex also causes stress: Oral sex is generally related to hygiene, therefore the partner can be self conscious and worried about his/her genital hygiene. If oral sex is performed on a daily basis, some people prefer to wax their pubic hair often. This is harmful because it can cause red bumps and burning sensation occurs. It is advisable to trim your pubic hair and wash it properly before engaging in oral sex.

3. A condom should be worn by the male during oral sex so that there is no risk of male fluid entering the woman's body.

4. A latex, which is made into a thin sheet called dental dam can be used on the vagina or anus. This creates a thin barrier between the mouth and the genitalia. Hence, chances of getting infected by sexually transmitted diseases are greatly reduced.

Oral sex can be pleasurable and fun, but the risks of getting sexually transmitted diseases like herpes, gonorrhea and crabs is not altogether misplaced. So it is advisable to use proper protection and to maintain hygiene before engaging in oral sex.

4 Ways to Have Safe Oral Sex - Necessary Precautions

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 testing in pregnancy should be done early so as standard care can be taken for the pregnant women.


- this hiv testing must be repeated in the third trimester, usually before 36 weeks of gestation. This should be done in women with hiv-seronegative and also in pregnant women who are at a high risk of developing hiv infection.


- expedited hiv tests should be performed at the time of delivery and labor and this is a must in women who have not been documented for hiv. The results of the test should be available in one hour of the test and the testing should be available 24 hours. In case the results are positive then, infant postnatal antiretroviral and intrapartum drug prophylaxis should be started immediately.


- women who have not been able to be tested for hiv at the time of labor and delivery are suggested expedited screening for hiv. Their screening can be done immediately postpartum or their babies should undergo screening. In case the infant and mother, both are positive, then infant antiretroviral drug prophylaxis should be started immediately. These mothers should avoid breastfeeding their babies, until the supplemental hiv tests are negative. In infants with positive hiv, prophylaxis should be discontinued and antiretroviral drug therapy should be started.


- in case of acute hiv infection during pregnancy, that is in the intrapartum period, or during breast feeding, initial testing can be performed with an antigen/antibody combination immunoassay. If the supplemental test is negative, then an additional test which is the virologic test (dna, rna) are necessary for the diagnosis of the hiv infection.
- if the mother is hiv positive then this information must be documented in the infant's medical record and also communicated to the infants care provider.
The knowledge of an antenatal maternal hiv infection allows the:
- women with hiv infection to get the correct antiretroviral therapy along with prophylaxis for the infections which might occur due to the immunocompromised state of the body. This also prevents and decreases the risk of transmission to their partners.
- when there is provision for antiretroviral therapy for the mother during pregnancy and labor along with antiretroviral drug prophylaxis for the baby there is less risk of perinatal transmission of the hiv.
- the hiv infected women should be counseled for a cesarean delivery. The option of an elective cesarean reduces the perinatal transmission of the hiv.
- the hiv women should be counseled about the risk of breastfeeding.

Identification and Management of Perinatal HIV Treatment

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.
