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?

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!

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.

4 Effects of HIV on the Body

HIV, which is short for Human Immunodeficiency Virus, penetrates your body and directly attacks your immune system. In this process, the virus weakens your body's natural defense mechanism against diseases and infections. A compromised immune system makes the body prone to minor infections, which healthy people would generally overcome. The virus itself doesn't cause any physical symptoms. It only serves to ease the entry of other bacteria and viruses into the body.

The following are some of the ways HIV affects your body:

1. Immune system

The human immunodeficiency virus destroys CD4 cells, the white blood cells that help the immune system ward off foreign substances. If left unchecked, HIV can develop into AIDS. During such time, the virus may damage the immune system to an extent that it wouldn't be able to ward off minor infections that a healthy immune system would. A person with HIV could thus suffer from fever, chills, sweats, shortness of breath, white spots in the mouth, fatigue, skin rash and weight loss from time to time.

2. Respiratory system

As HIV develops into AIDS, the body can contract infections such as pneumocystis pneumonia (PCP), tuberculosis and Kaposi's sarcoma. These conditions lead to serious respiratory problems. PCP is found to be one of the most common infections among people with HIV. 85% of the people would develop the infection if the condition is left untreated.

3. Skin problems

As in healthy individuals, many skin conditions can also occur in people with HIV or AIDS. But a compromised immune system heightens the condition and causes difficulty in treatment. Dermatitis, psoriasis, and hives are common conditions. They are also prone to a rare type of skin cancer known as Kaposi's sarcoma.

4. Gastrointestinal System

Gastrointestinal disorders are the most common ailments for people diagnosed with HIV and AIDS. Problems faced include diarrhea, nausea, vomiting, weight loss, abdominal pain and gastrointestinal bleeding. 50% of the people suffering from HIV encounter gastrointestinal disorders at some point of their illness.



4 Effects HIV has on the Body

HIV/AIDS is a type of sexually transmitted disease which is caused by the Human Immunodeficiency Virus (HIV). The HIV virus attacks the immune system and makes the body vulnerable to other diseases. AIDS is the last stage of the HIV infection; HIV takes about 10 to 12 years to fully culminate into AIDS. AIDS completely destroys the immune system and leads to fatal health conditions and diseases such as cancers and other infections because of AIDS.

Causes-

HIV is a retrovirus that infects the vital organs of the human immune system. The virus progresses in the absence of antiretroviral therapy. The rate of virus progression varies widely between individuals and depends on many factors (age of the patient, body s ability to defend against HIV, access to healthcare, existence of coexisting infections, the infected person s genetic inheritance, resistance to certain strains of HIV).

HIV can be transmitted through:

Sexual Transmission. It can happen when there is contact with infected sexual secretions. This can happen while having unprotected sex, including vaginal, oral and anal sex or sharing sex toys with someone infected with HIV.
Perinatal Transmission. The mother can pass the infection on to her child during childbirth, pregnancy, and also through breastfeeding.
Blood Transmission. The risk of transmitting HIV through blood transfusion is nowadays extremely low in developed countries, thanks to meticulous screening and precautions. Among drug users, sharing and reusing syringes contaminated with HIV-infected blood is extremely hazardous.
Contrary to popular belief, HIV can never spread by means of kissing as the virus cannot survive outside the body.

Symptoms-

The early symptoms of HIV appear within a few weeks of contamination by the virus. The early symptoms include headache, pain in the muscles and the joints, rashes and inflated lymph nodes. These symptoms tend to disappear within 2 to 3 weeks.
The next set of symptoms might appear after a few years and these are persistent. The symptoms include, but are not limited to fatigue, loss of body weight, inflated lymph nodes, fever, a sensation of numbness near the limbs, pain when you try to swallow, sores in the mouth and sweating at night.
If you are diagnosed with HIV, you should:

Try to maintain a daily diet containing vegetables, legumes, and fruits which provide you energy.
Try to include a little bit of fat, carbohydrates (at least 3 servings of vegetable per day), calcium (dairy products) and low-fat protein sources (generally 80-150 gram per day of fish, skinned chicken, low-fat cheese etc.) in your everyday meal.
Maintain a daily calorie intake of 17-25 calories per pound depending on whether the person is losing weight.
Vitamins and minerals are particularly necessary to repair the cells damaged by the HIV virus.
So, it is necessary to intake foods such as eggs, milk, peanuts, green vegetables, meat, beans and broccolis on a regular basis, if you have been diagnosed with HIV.

If you are suffering from HIV, you must maintain the following food safety measures:

You should try to restrict the intake of fat
Restrict your alcohol intake
You should try to avoid fast foods
You should also limit your regular sugar intake and should avoid foods with extra sugar

HIV/AIDS - Diet, Nutrition & Food Safety You Must Follow!

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.
