among the most common infections known. More than 12 million people in the United

States, including 3 million teenagers, are infected with STDs every year. The United

States has the highest STD rate in the industrialized world about one in ten Americans

will contract an STD during his or her lifetime. People who do not know they are

infected risk infecting their sexual partners and, in some cases, their unborn children.

If

left untreated, these diseases may cause debilitating pain or may destroy a woman’s

ability to have children. Some STDs can be cured with a single dose of antibiotics, but

many, such as (AIDS), cannot be cured. People with these diseases remain infected for

their entire lives. Those most at risk for contracting STDs are people who have

unprotected sex—that is, sex without using some form of contraceptive, those who have

multiple partners, and those whose sex partners include drug users who share needles.

Studies show that Americans between the ages of 16 and 24 are at bigger risk of catching

STDs than older adults are, because younger people are more likely to have multiple

sexual partners rather than a single, long-term relationship. Young people may also be

more likely to have unprotected sex and may be embarrassed to tell their sexual partners

they are infected. Young people may also be embarrassed or unable to seek medical

attention for STDs. This means that they are not only more likely to pass the disease to

other young people, they also have a greater risk of suffering the long-term consequences

STDs are transmitted by infectious agents—microscopic bacteria, viruses,

parasites, fungi, and single-celled organisms called protozoa—that thrive in warm, moist

environments in the body, such as the genital area, mouth, and throat. Most STDs are

spread while having sex , but other forms of sexual contact, such as oral sex, can also

spread disease. Some STDs are passed from a mother to her child before birth, when the

disease enters the baby’s bloodstream, during childbirth as the baby passes through the

birth canal, or after birth, when the baby drinks infected breast milk.

Some viral STDs, especially AIDS, may be transmitted by blood contact such as

open wounds, between people who share infected needles or received through a

transfusion of infected blood. Some people mistakenly believe that STDs can be

transmitted through shaking hands or other casual contact, or through contact with

inanimate objects such as clothing or toilet seats. Such transmissions are extremely rare

Chlamydia, caused by the Chlamydia trachomatis bacterium, is the most

commonly transmitted STD in the United States. About 500,000 chlamydia infections

are reported each year. But because chlamydia may not produce noticeable symptoms, it

often goes undiagnosed, and it is estimated that the true number of people infected with

chlamydia is nearly ten times the number of reported cases. People who do not know

they are infected may not seek medical attention and may continue to have sex,

unknowingly they’re spreading the disease. When symptoms do develop, men may

experience painful or burning urination or a discharge from the penis. Women may

experience burning urination, vaginal secretion, or mild lower abdominal pain. If left

untreated, chlamydia damages reproductive tissue, causing inflammation of the urethra in

men and possibly (PID) in women. PID can cause chronic, debilitating pelvic pain,

infertility, or fatal pregnancy complications. Chlamydia infections are diagnosed by

testing penile and vaginal discharge for the presence of the bacteria.

Gonorrhea, caused by the bacteria Neisseria gonorrhoeae, infects the membranes

lining certain genital organs. Although roughly 325,000 gonorrhea infections are reported

each year in the United States, experts estimate that closer to 800,000 people are infected

annually. Like chlamydia, gonorrhea is often symptomless, and men are more likely to

develop symptoms than women are. When present, symptoms may be similar to those of

chlamydia and include burning urination and penile or vaginal discharge. Untreated

gonorrhea can cause PID in women. Babies born to mothers with gonorrhea are at risk of

infection during childbirth; such infections can cause eye disease in the newborn.

Physicians diagnose gonorrhea by testing penile or vaginal discharge specimens for the

presence of Neisseria gonorrhoeae. Gonorrhea is treatable with several antibiotics,

although it has become resistant to treatment with many drugs in the past several decades.

A potentially life-threatening STD, is caused by the bacteria Treponema

pallidum. According to experts, there are an estimated 100,000 new cases of syphilis in

the United States each year. In the early stage of syphilis, a genital sore, called a chancre,

develops shortly after infection and eventually disappears on its own. If the disease is not

treated, the infection can progress over years, affecting the vertebrae, brain, and heart, and

resulting in such varied disorders as lack of coordination, meningitis, and stroke. Syphilis

is easily treated with penicillin, and the number of cases in the United States has dropped

considerably since 1982. It is up to ten times more common in some regions of the

southern United States than in other parts of the country. Syphilis during pregnancy can

be devastating to the fetus, causing deformity and death, and most pregnant women in the

United States receive screening for the disease in the first weeks of pregnancy so that the

disease can be treated before the fetus is harmed.

Genital herpes is caused by infection with the herpes simplex virus (HSV). Most

cases of genital herpes are due to HSV type 2. Some cases, however, result from genital

infections with HSV type 1, a usual cause of cold sores. Genital herpes causes recurrent

outbreaks of painful sores on the genitals, even though the disease often remains dormant

with no symptoms for long periods. In the United States, one in five people over the age

of 12 is infected with HSV type 2, and the vast majority of those infected, about 90

percent, do not know they have the disease. The symptoms of HSV can be treated with

antiviral drugs, such as acyclovir, but HSV cannot completely dismissed from the body, it

AIDS, the result of infection with the (HIV), is an incurable and deadly STD.

AIDS attacks the body’s immune system, leaving victims open to a wide range of

infections. While HIV can be transmitted by other means, sex is the most common means

of transmission. Women who are infected with HIV can pass the virus to their infants

during childbirth or, less likely in breast milk. Treatment options for people infected with

HIV include protease inhibitors, which can considerably increase survival. In spite of

widespread educational and prevention programs, experts estimates that there are 40,000

new cases of HIV each year in the United States.

Certain types of hepatitis virus can be spread through sexual contact. One hundred

times more contagious than HIV, hepatitis B is spread sexually and during childbirth:

Between 90 and 95 percent of all babies born to infected mothers will contract the disease

during birth. Hepatitis B attacks liver cells, leading to cirrhosis and possibly cancer of the

liver. In most cases hepatitis B is incurable, but strenuous chemotherapy can eliminate the

virus in some patients. There is a safe, effective vaccination for hepatitis B, and most

states are developing or already have initiated public school immunization programs.

Genital warts, transmitted by the during sexual contact, grow on the penis and in

and around the entrance to the vagina and anus. Although they are relatively painless,

genital warts significantly increase the risk of cervical cancer in women. Genital warts are

treatable with topical medications and can be removed with minor surgical procedures.

Trichomoniasis, is caused by the infection with protozoan Trichomonas

vaginalis, causes vaginitis, inflammation of the vagina causing burning, itching, and

discomfort. In men, trichomoniasis may cause similar problems in the urethra, called

urethritis. Trichomoniasis is usually easily treated with a single dose of antibiotics. It is

estimated that 3 million Americans are infected with trichomoniasis each year.

Unlike many serious diseases, STDs can be prevented by taking simple measures.

The most effective prevention method is abstinence—that is, not having sex completely.

No sexual relations means no risk of developing an STD. Practicing monogamy, in which

two partners do not have sexual relations with anyone but each other, also greatly reduces

the risk of spreading and contracting STDs. Latex are an effective, although not perfect,

form of protection from STDs. These rubber sheaths, worn over the penis or inserted into

the vagina, act as a physical barrier to organisms that cause STDs. However, condoms do

not cover all of the genital surfaces that may come into contact during sex, and the

likelihood of transmission of some STDs, especially genital herpes and warts, still exists.

Early diagnosis and precise treatment prevent the more serious consequences of infection,

while stopping the spread of STDs from person to person. This is most critical in STDs

that do not cause symptoms, because those infected often do not know they risk infecting

their sexual partners. Drug treatment programs must be completed, even if early doses of

drugs appear to soothe symptoms entirely. The infection may still persist in the absence

of symptoms, leading infected individuals to unknowingly spread the disease. Likewise,

exposure to small doses of antibiotics that do not kill the infection may enable the

infecting agent to develop resistance to the drug.

Public clinics screen patients at risk for STDs in order to diagnose and treat

diseases in the early stages. Clinics track the incidence of STDs in particular areas and

contact the sexual partners of infected individuals. By identifying and treating these

potential carriers, clinics are able to break the chain of STD infections. Several

organizations, such as the CDC and the World Health Organization, monitor and research

transmission of STDs on an international level in an effort to prevent local outbreaks

from reaching the size of an epidemic. For example, in many countries of the world, the

incidence of STDs increased during and directly after World War II (1939-1945), when

soldiers spending long periods of time away from home practiced unprotected sex with

different partners, many of whom carried STDs. When the antibiotic penicillin became

widely available in the following years, the same countries experienced dramatic

reductions in STD incidence. Beginning in the 1950s, however, the incidence of

gonorrhea began to rise as American sexual behavior changed. Strains of the disease

developed resistance to penicillin, and by the 1970s and 1980s the disease reached

epidemic proportions in young adult populations. Introduction of HIV into the human

population led to an international crisis that began in the 1980s and continues to this day.

Today record numbers of people are infected with genital herpes, and experts suspect that

this incurable disease is quickly surpassing chlamydia as the most common STD in the

United States.Cases of STDs are increasing in the late 20th century, even though the use

of condoms has increased since the onset of the AIDS epidemic. Public health officials

feel that many factors are probably responsible, among them trends in sexual behavior. In

the last several decades, the age at which people have sex for the first time has shifted

downward, while the average number of partners a person has sex with during his or her

lifetime has increased. Together, these trends increase the risk of exposure to an STD.
