Genital Herpes

Genital herpes, also commonly called "herpes," is a viral infection by the herpes simplex virus (HSV) that is transmitted through intimate contact with the mucous-covered linings of the mouth or the vagina or the genital skin. The virus enters the linings or skin through microscopic tears. Once inside, the virus travels to the nerve roots near the spinal cord and settles there permanently.
When an infected person has a herpes outbreak, the virus travels down the nerve fibers to the site of the original infection. When it reaches the skin, the typical redness and blisters occur. After the initial outbreak, subsequent outbreaks tend to be sporadic. They may occur weekly or even years apart.

Human Papillomaviruses (HPVs) and Genital Warts

More than 40 types of HPV, which are the cause of genital warts (also known as condylomata acuminata or venereal warts), can infect the genital tract of men and women. These warts are primarily transmitted during sexual contact. Other, different HPV types generally cause common warts elsewhere on the body. HPV infection has long been known to be a cause of cervical cancer and other anogenital cancers in women, and it has also been linked with both anal and penile cancer in men.

Chancroid

Chancroid is an infection caused by the bacterium Hemophilus ducreyi, which is passed from one sexual partner to another. It begins in a sexually exposed area of the genital skin, most commonly the penis and vulva (the female external genital organs including the labia, clitoris, and entrance to the vagina). Chancroid starts out as a tender bump that emerges 3 to10 days (the incubation period) after the sexual exposure. The cells that form the bump then begin to die, and the bump becomes an ulcer (an open sore) that is usually painful. Often, there is an associated tenderness and swelling of the glands (lymph nodes) in the groin that normally drain lymph (tissue fluid) from the genital area; however, the painful ulcer and tender lymph nodes occur together in only about one-third of infections. Chancroid is common in developing countries but is a relatively rare cause of genital ulcers in the U.S.

Gonorrhea

Gonorrhea is a bacterial infection caused by the organism Neisseria gonorrheae (also known as gonococcus bacteriae) that is transmitted by sexual contact. Gonorrhea is one of the oldest known sexually transmitted diseases. It is estimated that over one million women are currently infected with gonorrhea. Among women who are infected, a significant percentage also will be infected with chlamydia, another type of bacteria that causes another STD. (Chlamydia infection is discussed later in this article.)
Contrary to popular belief, gonorrhea cannot be transmitted from toilet seats or door handles. The bacterium that causes gonorrhea requires very specific conditions for growth and reproduction. It cannot live outside the body for longer than a few minutes, nor can it live on the skin of the hands, arms, or legs. It survives only on moist surfaces within the body and is found most commonly in the vagina, and, more commonly, the cervix. (The cervix is the end of the uterus that protrudes into the vagina.) It can also live in the tube (urethra) through which urine drains from the bladder. Gonorrhea can also exist in the back of the throat (from oral-genital contact) and in the rectum.

Chlamydia

Chlamydia (Chlamydia trachomatis) is a bacterium that causes an infection that is very similar to gonorrhea in the way that it is spread and the symptoms it produces. It is common and affects approximately 4 million women annually. Like gonorrhea, the chlamydia bacterium is found in the cervix and urethra and can live in the throat or rectum. Both infected men and infected women frequently lack symptoms of chlamydia infection. Thus, these individuals can unknowingly spread the infection to others. Another strain (type) of Chlamydia trachomatis, which can be distinguished in specialized laboratories, causes the STD known as lymphogranuloma venereum (LGV; see below).

Syphilis

What is syphilis?

Syphilis is an STD that has been around for centuries. It is caused by a bacterial organism called a spirochete. The scientific name for the organism is Treponema pallidum. The spirochete is a wormlike, spiral-shaped organism that wiggles vigorously when viewed under a microscope. It infects the person by burrowing into the moist, mucous-covered lining of the mouth or genitals. The spirochete produces a classic, painless ulcer known as a chancre.

What are sexually transmitted diseases (STDs)?

Sexually transmitted diseases (STDs) are infections that can be transferred from one person to another through any type of sexual contact. STDs are sometimes referred to as sexually transmitted infections (STIs) since they involve the transmission of a disease-causing organism from one person to another during sexual activity. It is important to realize that sexual contact includes more than just sexual intercourse (vaginal and anal). Sexual contact includes kissing, oral-genital contact, and the use of sexual "toys," such as vibrators. STDs probably have been around for thousands of years, but the most dangerous of these conditions, the acquired immunodeficiency syndrome (AIDS or HIV disease), has only been recognized since 1984.

Avoid high-risk sexual behaviors

High-risk sexual behavior can lead to the acquisition of sexually transmitted illnesses such as gonorrhea, syphilis, herpes, or HIV infection. High-risk sexual behavior is also known to spread human papillomavirus infection, which can lead to cervical cancer in women and other anogenital cancers in both men and women. High-risk sexual behaviors include the following:
  • Multiple sex partners
  • Sex partners with a history of the following:
    • Intravenous drug use
    • Venereal disease (sexually transmitted diseases or STDs)

Adverse consequences of high-risk sexual behavior:

  • Transmission of HIV and other sexually transmitted diseases (chlamydia, gonorrhea, syphilis, genital herpes)
  • Transmission of hepatitis B (50% of hepatitis B infections are due to sexual transmission) and, in rare instances, hepatitis C
  • Transmission of human papilloma virus (HPV), which can cause genital warts and anogenital carcinomas, most commonly cancer of the uterine cervix
  • Unplanned pregnancy

Avoid other high-risk behaviors

  • Driving under the influence of alcohol or drugs
  • Driving while sleep-deprived
  • Reckless driving and speeding, "road rage"
  • Driving while using cell phones, texting, or performing other tasks
  • Motorcycle (and bicycle) riding without helmets
  • Possession of firearms and guns without proper training and storage
  • Smoking in bed

Adverse consequences of high-risk behaviors:

  • Motor vehicle accidents account for 40%-50% of accidental deaths.
  • Motorcycle accidents are a major cause of serious head injuries.
  • Firearms and guns account for a significant proportion of deaths among adolescents due to male suicide and homicide.
  • Smoking in bed can lead to burn injury and death.

Eating (diet)

All humans have to eat food for growth and maintenance of a healthy body, but we humans have different requirements as infants, children (kids), teenagers, young adults, adults, and seniors. For example, infants may require feeding every four hours until they gradually age and begin to take in more solid foods. Eventually they develop into the more normal pattern of eating three times per day as young kids. However, as most parents know, kids, teenagers, and young adults often snack between meals. Snacking is often not limited to these age groups because adults and seniors often do the same.

Physical activity and exercise

Physical activity and exercise is a major contributor to a healthy lifestyle; people are made to use their bodies, and disuse leads to unhealthy living. Unhealthy living may manifest itself in obesity, weakness, lack of endurance, and overall poor health that may foster disease development.

Avoid tobacco use

Tobacco use is the most important preventable illness and cause of death in the U.S., according to the National Cancer Institute (NCI). Tobacco use was estimated to be the cause of 443,000 deaths in 2010 in the U.S.
Tip:
  • Stop smoking tobacco; start to stop today (it takes about 15 years of nonsmoking behavior to achieve a "normal" risk level for heart disease for those that smoke).
  • Stop using chewing tobacco to avoid oral cancers.

Avoid excessive alcohol consumption
