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!

Most of us are affected by diseases, which spread through physical contact, but most of us do not consider it important to get them checked, due to which they turn into major ailments. Sexually transmitted diseases (stds) are infections, which are transmitted through any kind of sexual contact. The organism that causes the disease is transmitted from one person to the other during sex intercourse. Sometimes stds can be asymptomatic (no symptoms or signs)

Here are some stds that you should be informed about:

1. Gonorrhoea: genital infection caused by bacteria is called gonorrhoea, its symptoms include 

 Bloody vaginal discharge
 Painful urination
 Heavy period bleeding
 Anal itching

2. Chlamydia: bacterial infection in the genital tract is called chlamydia. Chlamydia is usually difficult to diagnose, its symptoms include

 Pain during urination
 Pain in lower abdomen
 Vaginal discharge
 Painful intercourse
 Bleeding between menstrual cycles

3. Syphilis: the bacterium treponema pallidum causes syphilis, its symptoms include

 Rashes
 Sores in the mouth, anus or vagina
 In later stages, it causes nerve and organ damage

4. Genital herpes: the herpes simplex virus (hsv) causes herpes. Signs and symptoms include-

 Small red bumps or ulcers in the anal, genital and other areas
 Itching or pain around the genital area, thighs and buttocks

5. Human papillomavirus (hpv) and genital warts: genital warts are caused by hpv. It infects the genital tract. Hpv has been linked to cervical cancer, its symptoms include

 Small swellings in the genital area
 Itching
 Bleeding during sex

6. Chancroid: chancroid is a bacterial infection. The bacterium haemophilus ducreyi causes chancroid, its symptoms include

 Development of red bumps on the skin folds covering the genitals
 Pain during urination
 Burning sensation during bowel movement

7. Ectoparasitic infections: ectoparasitic infections are caused by small parasitic bugs like mites or lice. The parasites usually affect the hair or skin. Scabies and crabs are common parasites that cause such infections. They both cause intense itching and visible rashes.

8. Human immunodeficiency virus (hiv) and acquired immunodeficiency syndrome (aids): the virus that causes aids is called hiv. It can spread through blood, vaginal fluids, semen and breast milk. Unprotected sex or sharing needles with an infected person is how the disease spreads. It includes symptoms, such as

 Slight fever
 Fatigue
 Muscle aches
 Weight loss.

Most Common STDs in Women

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

People who suffer from human immunodeficiency virus, commonly known as'hiv, are known as hiv positive people. The virus is the agent of aids that is currently incurable. Hiv is known to alter the human immune system and makes people much more susceptible and vulnerable to diseases and infections. 

Body fluids such as semen, blood, breast milk, vaginal fluids etc. Of an infected individual contains the virus, which can be passed from one person to another during blood-to-blood and/or sexual contact. Hiv positive women may even pass on this virus to their children during pregnancy, delivery or by breast feeding them. Hiv is also transmitted during oral, anal or vaginal sex, by contaminated hypodermic needles and by blood transfusion. 

Mentioned below are a few issues that a hiv positive woman have to face apart from discrimination and stigma, fear of infecting their children or partners, violence and abandonment. 

1. Menstrual disorders: changes in menstrual cycles are frequently reported by hiv infected women. However, menstrual dysfunctions are due to varied reasons that aren't directly related to the disease. Although most of the hiv positive women suffer from amenorrhea i. E. The unusual absence of periods, it is not just due to hiv but also because of weight loss or immunosuppression. 
 
2. Contraception: it is very important that the contraception a hiv positive woman chooses not only acts as birth control, but also to prevent the transmission of sexually transmitted diseases and hiv. Although condoms do not provide exceptional pregnancy prevention, they are excellent at preventing transmission of the hiv virus. Permanent sterilization is usually the most chosen contraceptive method for hiv serodiscordant couples.

3. Surgical complications: hiv positive women are at a higher risk of undergoing gynecologic surgery. This is because they are more vulnerable to pelvic infectious disease that requires surgical intervention. There is also a greater risk of developing vulvar cancer in hiv positive women. 

4. Fertility: there has been an increase in the number of seropositive women contemplating pregnancy and childbirth. Most couples resort to assisted reproduction to lower the risk of horizontal hiv transmission. Studies show that undergoing hiv treatment and having an undetectable viral load is helpful in preventing the transmission of hiv. It is important to consult a medical expert if you are unable to get pregnant after at least 6 months of trying. Fertility problems are more common in hiv positive women than hiv negative women.

Issues for HIV Positive Women

An STD is transmitted by means of physical contact and intercourse. These diseases are caused by parasites, virus or bacteria. Usually, STDs are preventable provided you make the right choices concerning your sexual health. Refraining from sex isn t a feasible idea at all. 

But fortunately there are alternatives too to curb the menace that STDs are:

Abstain: The most effective way to avoid STIs is to abstain from sex.
Mutual monogamy: Two people who have sex only with one another don t have any opportunity to bring a new STD into the relationship. If you and your partner have been tested and are healthy, remaining faithful to each other is a very good way to reduce your chances of contracting an STD.
Get Vaccinated: One important prevention tool against STIs is vaccination. Currently, vaccines are available to protect against infection with HPV, hepatitis A and hepatitis B. Talk to your healthcare provider to see which vaccines might be recommended for you.
Protect Yourself: Condoms work really well in stopping most STIs from being passed from an infected partner to another when they are used consistently and correctly every time a person has oral, vaginal or anal sex. Consistently and correctly means that a person makes sure they use a condom every time they have oral, vaginal or anal sex and put it on and use it the right way.
Avoid alcohol and drug use: Avoiding alcohol and recreational drug use reduce the risk of contracting an STI, having an unwanted pregnancy, or being coerced to have sex. Alcohol and drug use can reduce our ability to make good decisions. It may also make us more likely to be talked into participating in an activity without being able to give our full consent.
Coping and Support
It's traumatic to find out you have an STI. You might be angry if you feel you've been betrayed or ashamed if there's a chance you infected others. At worst, an STI can cause chronic illness and death, even with the best care in the world.

Between those extremes is a host of other potential losses   trust between partners, plans to have children, and the joyful embrace of your sexuality and its expression. If in doubt, don't hesitate to visit a skin specialist or a physician.

STDs - 5 Ways You Can Avoid Them

Sexually Transmitted Diseases (STDs) are infections that you can get from having sex with someone who already has the infection. The causes of STDs are bacteria, parasites, and viruses. These infections often do not cause any symptoms, and can still be passed unknowingly from the infected partner to the other. However, some common symptoms include genital itching, lesions, flu / fever like symptoms and feeling pain / pressure in the lower part of the stomach.

There are many kinds of STDs including Chlamydia, gonorrhea, genital herpes, syphilis and HIV.

The important thing to understand and know is that these STDs can be prevented.

3 ways of preventing STDS are:

1. Precautions before having sex

There are some things you can do to reduce your risk of contracting STDs before having sex. This include:

  Limiting the number of sexual partners
  Talking honestly with partners about your sexual history
  Getting tested, along with your partner, before having sex
  Getting timely vaccination against HPV and HBV

If you have been diagnosed with an STD you should tell your partner about it and also explicitly ask your partner if they have had an STD.

2. Practice safe sex

Use a latex condom every time you have sex and use a water-based lubricant. If your sex life involves intercourse, anal or vaginal, make up your mind to never have sex without a condom. If you or your partner is at a high risk of STDs, be consistent about barrier use during oral sex as well. Avoid sharing towels or underclothing to reduce the risk of an STD. Check the expiration date of the condom and make sure that it has an air bubble, which shows it has not been punctured. Dispose the condom properly and never reuse it.

3. Don't drink Alcohol or use drugs before having sex

It's impossible to make responsible choices about your sex life under the influence of drugs or alcohol. When you are under the influence of any one of them, you are not in your mind and are likelier to choose a partner you wouldn't have picked otherwise. In that case, you may be at a higher risk of contracting an STD. Also, if you are on birth control pills and you vomit, the pills could lose some effectiveness.
