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!

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

One of the most common physically transmitted diseases is chlamydia. Chlamydia is a type of infection caused by the bacteria "Chlamydia trachomatis". The symptoms of Chlamydia are similar to the symptoms of Gonorrhoea (a bacterial sexually transmitted infection). Chlamydia infection causes permanent fallopian tube damage in women, leads to future ectopic pregnancy (the fertilised egg attaches itself outside the uterus) and infertility.

Symptoms of Chlamydia 
Men and women afflicted with chlamydia exhibit different symptoms.
The symptoms of chlamydia in women include:
1. Abnormal, sometimes foul-smelling, vaginal discharge
2. Bleeding between menstrual cycles
3. Painful periods
4. Abdominal pain, accompanied with fever
5. Pain during intercourse
6. Burning or itching around or in the vagina
7. Painful urination

Men usually display the following symptoms if they have chlamydia:
1. Minimal amounts of cloudy or clear discharge from the head of the penis
2. Painful urination
3. Itching and burning around the slit of the penis
4. Swollen and painful testicles

Treatment options available
1. Chlamydia is diagnosed by taking a swab from the cervix (in women) or the urethra (in men). These swabs will be sent to the laboratory for analysis. Urine samples can also be taken to check for the appearance of bacteria.

2. Since chlamydia is a bacterial infection, it can be easily treated with antibiotics. Oral antibiotics such as azithromycin or doxycycline are commonly prescribed by doctors. Azithromycin is usually prescribed in a large, single dose. The dose may also be stretched out for five days. Doxycycline is taken two times daily for a week.

3. With the right antibiotic therapy, the infection will clear up in 1 to 2 weeks approximately. It is very important that you finish the medication course if you wish you heal completely without having to suffer from further bouts of this disorder.

4. Women with critical chlamydia may need hospitalisation, pain medicine and IV (intravenous, or directly through the vein) antibiotics. Pregnant women with chlamydia infection can be safely cured with antibiotic such as erythromycin ethylsuccinate, amoxicillin and azithromycin.

Your partner needs testing and treatment as well to avoid further spread and reinfection. It is vital not to engage in any sexual activity while the treatment is ongoing. A further retest should be done three months later to make sure the infection is rectified.

Symptoms of Chlamydia and Ways to Treat the Disease

There is a contrast between intimacy satisfaction and intimacy happiness. Happiness tends to be a byproduct of the relationship. Therefore, while it just takes one partner to be sexually satisfied, it takes two to make the conditions for sexual happiness. A key indication of sexual bliss in a relationship is a couple's capacity to endlessly rejuvenate the sexual energy between them. Consequently, the term sexual happiness depicts couples who can revive, reestablish and extend their sexual desire with each other for a very long time or even forever. Here are a few ways through which one can integrate happiness and sexuality:

Since sexual happiness is a result of the relationship, both the partners need to be happy with each other in general to achieve happiness rather than satisfaction.
Staying in shape can be very beneficial. Being sound and fit promotes better sex. Not just are fit individuals perform better sexually, but also it is proven that healthier and fit individuals have a more noteworthy longing for sex. There are numerous reasons behind this. Healthy, fit individuals are not only more joyful, but also physiologically, they are capable of producing more sex hormones due to a number of other health factors.
Enthusiasm is not found in sex; it is found in individuals. To completely grasp sexual enthusiasm, you should be completely present in the moment. As such, you should bring your psyche, body, and soul to your partner. This implies being conscious, aware, and present mentally as well as emotionally.
Decreasing or managing sex levels can also help one integrate happiness and sexuality. Life is clearly unpleasant many times, and our reaction to all the anxiety can be devastating when it comes to sexual experiences. Not only does a lot of stress or anxiety decrease the yearning for sex, it also additionally hinders sexual performance. Hence, one should vent out to their partners or try therapy or yoga for stress release.
Routine tend to repel romance and consistency cools the flames of sexual excitement and energy. To neutralize these twin constrains, you should deliberately plan and design different rituals of sexual pleasure. Indulge in customs of joy and particular actions, thoughts, activities, and exercises like back rub, animate, and stimulation of the sexual and emotional pleasures.
Being happy in general is very important. Being cheerful and idealistic is the establishment of numerous parts of a successful life. Inquiring about actions that make your partner happy are more advantageous, beneficial, and have better connections, including better and more continuous sex.
Sex is very important in a relationship for knowing and feeling that your partner still fancies you, yet having sex once a week is a practical and an achievable objective for people who tend to be very busy. A study demonstrates that regular sex additionally makes individuals more joyful than a high income.

Sexual Happiness and Satisfaction - How You Can Integrate Them?

Hiv or the human immunodeficiency virus is the lentivirus which causes hiv infection and leads to acquired immunodeficiency syndrome or aids.

The symptoms of hiv vary from person to person. There are three main stages of hiv infections, where each stage has different symptoms.

Here are some facts about the three stages of hiv infections along with the accompanying symptoms.

Acute hiv infection stage
This is the first stage of hiv infection and after three to four weeks of becoming hiv infected, people experience symptoms, which are similar to flu. This flu usually does not last more than two weeks.

Symptoms include:
Fever
Rashes on the body
A sore throat
Swelling of different glands
Headache
Joint and muscle pain
Improper digestion

These symptoms appear and indicate that the body is reacting to the hiv. Infected cells circulate throughout the blood, and the immune system produces hiv antibodies in order to attack the viruses. This process is termed as seroconversion, and it takes place within 45 days of getting infected. The levels of virus in your blood are quite high during this stage.

Clinical latency stage
This is the second stage of hiv infection, which follows the early stage. This stage is also known as chronic hiv stage. During this stage, hiv is active, but is reproduced at a very low level. People in this stage may not receive symptoms related to hiv or may get mild indications.

In case of people who do not take medicines for hiv treatment, this stage lasts for a long period. Some people, however, progress faster through this stage. Medicines should be taken to keep the virus in check. During this stage, people can transmit hiv to others very easily in spite of not experiencing any symptoms. People who are on medication stay suppressed virally and have a low level of hiv in their blood, and the risk of transmission is less.

Symptomic hiv infection or aids stage
This is the third stage of hiv infection, which is characterized by severe damage to the immune system of an hiv-virus affected person. A patient is likely to have serious infections and gets bacterial or fungal diseases. The infections are termed as opportunistic infections. The patient is now said to be having aids.

The symptoms of this stage are:
Loss of weight
Diarrhoea
Sweating at night
Fevers and persistent coughing
Problems in the mouth and skin
Infections on a regular basis
Illness and development of other diseases.

Hiv infection affects the body via three stages and leads to aids in the third stage. Each stage is accompanied by several symptoms.

Stages and Symptoms of HIV Infections

Hearing that a person is HIV positive instantly makes us wary of him or her and unconsciously we may begin avoiding social interactions with them. However, HIV does not spread through the air or by water and hence there is no reason to ostracize HIV positive people. To understand how to prevent the transmission of HIV it is essential to first understand how the virus is transferred from one person to another. There are three ways in which this virus can be transmitted from an HIV positive person to another. These are:

Through blood
Through bodily fluids such as semen and vaginal or rectal fluids
From a mother to a child
Keeping this in mind, here are a few ways to prevent the transferring of HIV from one person to another:



Use only Disposable Syringes: Getting pricked by a needle that has been used on a HIV positive patient can increase your risk of suffering from the disease. Hence, insist on using a fresh needle for blood tests etc. Also ensure that the syringe and needle and destroyed after being used.
Registered Blood Banks: In case you need a blood transfusion, get blood only from registered blood banks. These blood banks need to run HIV screening tests before collecting blood and hence are guaranteed to have only HIV negative blood as opposed to local quacks.
Use a Condom: The only way to prevent the transference of HIV cells while having intercourse is by using a condom. This is essential not only for vaginal intercourse but for anal intercourse as well.
Get Tested: Today, an HIV screening test can be easily done and your results are guaranteed to be kept confidential. STDs can increase your risk of getting infected with HIV or spreading it to others. Get tested regularly for STDs and insist that your partners are checked for it as well. This is crucial if you have more than one sexual partner.
Limit the Number of Sexual Partners: The more number of people you have sex with, the higher your chance of getting infected with the virus and transmitting it to others. Remember, HIV has no overt symptoms that are visible to the naked eye.
HIV cannot be cured but it can be controlled through medication. Hence, if you suffer from this disease, follow the doctor's prescription religiously to prevent transmitting the virus to your partner. If you wish to discuss about any specific problem, you can consult a doctor.
