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?

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. Though the researches imply that sexual problems are common all across the globe; 43% of women along with 31% of men are affected by some sort of dysfunction; however, it is something that most people are hesitant to talk about. But thankfully enough, most cases of sexual problems can be effectively treated, and can be prevented from occurring again, by sharing your concerns with a qualified doctor. You should consider visiting the doctor along with your partner.

What leads to sexual problems?
Sexual problems can be caused either due to physical or psychological reasons. Many medications and clinical conditions can cause a variety of sexual dysfunctions, and these physical conditions include heart and vascular disease, high levels of blood sugar and blood pressure, any kind of neurological disorder, chronic diseases of the kidneys, liver and lungs, and hormonal imbalances. In addition to this, the side effects stemming from any medicine, including antidepressant drugs, can cast a harmful impact on the sexual desire and its normal functioning. On the other hand, psychological causes refer to the stress caused due to work pressures, anxiety, depression, excessive concern about sexual performance, feelings of guilt, and relationship problems.

What are the common sexual problems?
What leads to sexual problems can cause a wide variety of issues in both men and women. While erectile dysfunction is most commonly found in men, vaginal dryness is the most common issue in women. Sexual dysfunction can take a variety of forms, and it is not plainly confined to the dysfunction or simple disinterest in sex, which is commonly termed as lack of sex drive. It can also involve pain while having sex or an inability to maintain the erection or experiencing pain while getting an orgasm. There are some people who experience excruciating pain during intercourse, which is often accompanied with a burning sensation.

All couples have the right to enjoy a happy and healthy sex life, which can be considered a crucial aspect of any relationship. So, if you are having any kind of difficulty that is interrupting your lovemaking, it is imperative to speak with your doctor to get the right diagnosis, and discuss openly with your partner to find out the ideal solution of your sexual problems.

Sexual Problems - Things That Can Lead to It

Spread of HIV infection from a woman who has transmits HIV to her child during pregnancy, childbirth (labor and delivery), or breastfeeding (breast milk) is called as  Mother to child  transmission (MTCT) of HIV. It is also termed as the perinatal transmission of the HIV infection or  vertical  transmission. In the absence of medical intervention, perinatal transmission rates are very high, between 20-45% in different parts of the world. In various regions of the African subcontinent a large number of HIV infected children are present. It is a major cause of deaths in teens and adolescents in that region. 

Almost 90% of all HIV infected children live in the sub-Saharan Africa. In some districts of AP, Karnataka, Maharashtra and TN that were highly HIV-prone, we have several HIV infected children and adolescents. The virus replicates in the body and affects the immune system. Due to decreased immunity, various opportunistic infections enter the body and cause AIDS related symptoms. Prevention of HIV infection in infants and young children is now a high priority and has been the rallying point for enhanced prevention efforts. MTCT HIV infection can be prevented with adequate measures by way of Anti-retroviral treatment (ART). All expecting mothers who are HIV infected should have access to the preventive medical services throughout the gestation period, during labor and also during breastfeeding. 



Proper provision of resources with skilled staff and awareness programs can help in avoiding new infection cases. Breastfeeding is the primary source of transmission of infection from mother to child. Basically, once ART is started in an HIV infected pregnant woman that should continue forever. With proper ART course, chances of MTCT are near Zero. At the Unison Medicare & Research Centre; which is India s first fully comprehensive clinic for HIV Care and infectious Diseases, during last decade, not a single MTCT has occurred after treating more than 160 such HIV infected mothers. Even prior to that MTCT rate was lower than 1%. Our motto has been making the mothers virally suppressed commensurate with the global principle of  Undetectable = Untransmittable ! In fact now more and more HIV infected couples have been coming forward for an elective pregnancy. Even HIV un-infected children orphaned by AIDS or living with sick caregivers are at the great risk of emotional and physical abuse, which in turn increases the child s vulnerability to HIV infection. 

Reduction of risks to these vulnerable children is of great importance and various programs are being implemented for the welfare of orphans and vulnerable children. Various risk factors that are implicated in the transmission of HIV infection from mother to child are as follows: 

Increased viral load 
Genital tract viral load 
Reduced CD4 cell count 
Unprotected sexual intercourse with infected partner 
Smoking, Substance and drug abuse 
Deficiency of Vitamin A and other essential nutrients 
Presence of other Sexually transmitted diseases (STDs) 
Pre-term delivery 
Placental disruption 
Invasive monitoring of the fetus 
Breast feeding In most cases, HIV will not cross through the placenta from mother to baby. 
In an otherwise healthy mother, risk of child getting infected is low. Prenatal visits shouldn t be increased until a complication arises. The physician should observe symptoms of AIDS and pregnancy-related complications on a regular basis. HIV may be the direct cause or a marker of a complex interaction of related medical and social conditions that affect pregnancy. Most HIV positive women are usually asymptomatic and have no major obstetrical problems during their gestation period. They should receive similar obstetric antenatal care as the HIV-negative women, unless indicated by the need to provide specific treatment for HIV related conditions. There is no evidence of a need to increase the number of antenatal visits, provided there are no complications of the HIV infection, although additional counseling sessions may be required to reassure the mother and family. 

Care of the HIV positive woman during pregnancy should include ongoing counseling and support as an integral part of the management. Invasive diagnostic procedures, such as chorionic villus sampling, amniocentesis or cordo-centesis should be avoided wherever possible, due to a possible risk of infection of the fetus.

How Can We Achieve HIV-Free Generation?

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

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!

Chlamydia is a Sexually Transmitted Disease. It is generally found in men and women under the age of 25. Researchers have found that in the United States about 2.9 million individuals develop this disease every year. 

Here are things that you must know about the disease:

What is it all about?
It is caused due to bacterial infection and is transferred sexually. You can be infected with disease by having vaginal, oral or anal sex with the patient. You must be aware of the fact that you can develop chlamydia even if your partner doesn t ejaculate inside your vaginal tract. If you had suffered from this disease in the past, you can still get it again by having unprotected sex with an infected person.

What are the symptoms of this disease?
There aren t any obvious symptoms for this disease. Most of the patients show no sign of developing this disease. Thus, you never get to know when you were infected actually. However, some patients do reflect some symptoms after 4 to 5 days of infection. These symptoms include abnormal penis or vaginal discharge and painful, burning urination. Men can also develop a bleeding rectum.

How do you know for sure that you are infected?
Well, you can get yourself tested to confirm about the infection.

What happens if you don t get treated?
If the patient doesn t seek medical help, he or she is posing threat to his or her health. Women may develop pelvic inflammatory diseases, infertility or ectopic pregnancy. In men, it can cause pain and fever as the infection spreads along the tube carrying sperm.

Is there any treatment?
This disease is curable. But it is important to avoid sexual contact with anyone during the period of treatment or medication. First, you need to undertake the test to confirm the infection. You shouldn t have sex for seven days after the treatment is over. It is advisable to get yourself tested thrice in a year.
