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.

Chlamydia - Things You Must Know About It!

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

Sexually Transmitted Diseases (STDs) are the infections that spread primarily from unprotected sexual intercourse or any kind of sexual contact. Men, like women, are equally prone to contracting STDs on having unprotected sexual intercourse; anal, vaginal or oral. Having multiple sex partners just increases the risks of it. So, you need to consult a specialist sexologist if anything these sort of things happening to you:

Common STD Symptoms in Men

Blisters on or around penis 

Spots, bumps or lesions on the penis 

Discharge (clear, white, or yellow) 

Oozing from the tip of the penis (thick or thin) 

Painful urination 

Painful ejaculation 

Itching on the tip of the penis 

Rash on the penis, testicles, or groin

Here is a list of STDs for men

Chlamydia- Chlamydia is a type of bacterial STD transmitted during oral, anal or vaginal sex with an already infected person. Some of the symptoms of Chlamydia in men are swollen testicles, penile discharge or pain while urinating.

Gonorrhea- This is another bacterial infection, majorly affecting the urethra, anus or the throat and primarily spreads through vaginal, oral or anal sex with someone already suffering from it. The symptoms are quite similar to those of Chlamydia.

Hepatitis B- Hepatitis B Virus (HBV) is the cause of the disease Hepatitis B and can cause severe inflammation of the liver. It spreads from one person to the other on coming into contact with the bodily fluids or blood of the person affected. Few signs of Hepatitis B include jaundice, vomiting, nausea, body aches, mild fever, lethargy and appetite loss.

Herpes (Simplex) - It is a viral infection caused by the herpes simplex virus (HSV) and generally tends to develop on or near to the mouth and the genitals. Primarily, herpes spreads through direct contact with the genitals or mouth of a person already diagnosed with the same.

Syphilis- Another bacterial Sexually Transmitted Disease, unprotected oral, vaginal and anal sex are the primary carriers of this disease. It is considered to be one of the most serious STDs because the risks of contracting HIV (Human Immunodeficiency Virus) get magnified once infected with Syphilis.

Human Papillomavirus (HPV) - In men, HPV is capable of causing cancers in the throat, anus or the penis. It is either passed on through skin-to-skin or unprotected sexual contact with an infected partner.

Preventing STDs

Many people can be infected with an STD without experiencing any visible symptoms. This means that practicing safe sex is crucial if you want to prevent STD infection.

The only way to completely prevent an STD is abstinence from any type of sexual contact or contact with open sores and bodily fluids of an infected person. But there are other ways to prevent STDs too.

Condoms during intercourse and dental dams or barriers during oral sex are proven effective when used correctly. Refraining from sex with multiple partners and instead opting for a monogamous sexual relationship can also help to prevent STDs. To understand it better and get treated you can always consult a sexologist.

Common STDs in Men

The year 2014 has seen a massive increase in the number of patients affected by Gonorrhoea. The most infected age group is between 15 and 24. This is mainly due to lack of knowledge in this age group about the disease. Here are some facts about Gonorrhoea that one must know.

Gonorrhoea Transmission
Gonorrhoea, also known as drip, is transmitted when a normal person comes in contact sexually with an infected person. Infected fluid of a mother can also pass to her newborn infant during delivery. The disease can affect both the genders.

Cause of Gonorrhoea
Neisseria gonorrhoeae bacteria cause the disease. The bacteria grow in mucus membranes and usually grow in the warm and moist areas of humans' reproductive tracts such as uterus and fallopian tube of women. These can also grow in anus, mouth as well as throat. As a matter of fact, the infection can be passed even via oral or anal sex.

Symptoms of Gonorrhoea
An infected person will develop symptoms of the disease in 2 to 14 days. Men may feel burning or painful sensation while urinating. Other symptoms are as follows:

1. Swollen and painful testicles
2. Swollen or redness at the tip of the penis
3. Penis may have a drip or discharge
4. Frequent urination
5. Recurrent soreness of throat

Females have milder symptoms of the infection. This makes it difficult to diagnose, and is sometimes misinterpreted as common vaginal yeast or other bacterial infection.

Following are a few symptoms of the disease in women:

1. Burning or painful urination
2. Frequent urination
3. Vaginal discharge
4. Soreness in throat
5. Fever
6. Lower abdominal pain
7. Pain while sexual intercourse

If the disease is not treated, infection spreads in blood stream leading to rashes, fever and even pain in the joints. Such unnoticeable symptoms make it difficult to treat.

Testing Methods of Gonorrhoea
One method is that penile or vaginal discharge samples are taken from patients and examined under a microscope by adding reactive stain. However, this is not an accurate assessment.
Another test is conducted where exposing samples are incubated. In case of infection, colony of gonorrhoea shows growth. Preliminary test may take 24 hours. Final assessment may take around three days. Samples can be from the patient's anus, joint fluid, blood, throat, vagina or tip of the penis.

Treatment
The disease is treatable under proper medical supervision. However, the bacterial resistance to Azithromycin drug has made it more difficult for treatment.

Protection
It is highly recommended to have a protected intercourse. Women of age group less than 25 need to have STI evaluation once a year.

Know All About Gonorrhoea

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.
