Sexually Transmitted Diseases

Sexually Transmitted Diseases

According to the Websters’ dictionary, a sexually transmitted disease, or commonly termed STD, can be defined as any of various diseases transmitted by direct sexual contacted that include classic venereal diseases (as syphilis, gonorrhea, and chancroid) and other diseases (as hepatitis A, Hepatitis B, giordiasis, and AIDS) that are often or sometimes contracted by other sexual means (Internet 3). This lab report will be dealing with three specific types of STDs each from a different origin.

Information will be given on each STD with reference to their common/scientific names, life cycle, transmission, and other key factors that influence and maintain the existence of the STD. This report deals with what may be everyday termed diseases however, these STDs affect one in four adolescents before the age of eighteen. Though these STDs are so common and spoken of so often, without early diagnosis and treatment they pose a serious and may be, even a fatal treat to someone who is infected and also their sexual partners or just innocent people who have come into contact with an infected person.

Herpes Simplex Virus type 1 (HSV-1) The viral disease that will be discussed is the Herpes Simplex Virus type 1 (HSV-1). This STD as stated before is a viral disease, of which a virus can be defined as any of various submicroscopic parasites of plants, animals and bacteria that often cause disease and that essentially of a core of RNA or DNA surrounded by a protein coat. Unable to replicate without a host cell, viruses are typically not considered living organisms. HSV-1 is usually associated with infections of the lips, mouth, and face.

It is especially common in children between the ages of one and three years old and may cause lesions inside the mouth and inflamed gums. It causes cold sores or fever blisters and is transmitted by something as simple as oral or respiratory secretions (for example, sneezing or coughing can transmit the virus). Most people have in one point of their life been affected with the type 1 virus by the age of 20. In addition to oral and genital lesions, the virus can also cause an infection of the eye involving the eyelid, conjunctiva, and cornea.

A finger infection called herpectic whitlow affects health care providers because of exposure to lung and mouth secretions during procedures and young children. The herpes virus can also affect the fetus and cause congenital abnormalities. Infection occurs after exposure to the virus through a break in the skin, or through mucus membranes. There is strong evidence that the virus may be transmitted even when the symptoms are not present. The virus spreads to nerve cells within the body, and then to other mucosal skin surfaces.

The virus remains dormant in the body after an active infection and recurrences of the symptoms can take place at a later time. Recurrences may be precipitated by overexposure to sunlight, fever, stress, or certain foods and drugs. Additional symptoms that may be associated with this disease are enlargements of lymph nods in the neck or groin, vaginal discharge, sore throat and memory loss. Physical findings of blisters may be sufficient to diagnosis the herpes simplex. With regards to treatment, this all depends on the severity of the infection.

Some cases are relatively mild and may not require treatment. Anesthetic mouthwashes such as 2% lidocaine or baking soda may reduce the pain of lesions inside the mouth. Alcohol-based mouthwashes should not be used. Gentle cleansing of skin lesions with soap and water is recommended. Warm baths may reduce the pain of the genital lesions. Oral Acyclovir (Zovirax) may be prescribed to suppress recurrent eruptions. The lesions generally heal on their own in 7 to 10 days however, once infected, the virus stays in the body for the rest of a person’s life and recurrences of active infection may happen.

Chlamydia Chlamydia trachomatis Chlamydia trachomatis is a bacterium that can cause the STD Chlamydia. A bacteria is any of the unicellular, prokaryotic microorganisms of the class SCHIZOMYCETES which may vary in terms of morphology, oxygen and nutritional requirements, and motility and may be free-living, sciprophytic, or pathogenic, the latter causing disease in plants or animals. Chlamydia infection is very common among young adults and teenagers. However, many people do not know that they have chlamydia, because although they are infected they may not have and symptoms.

About 75% of infected women and half of infected men have no symptoms of chlamydia. Transference is through sexual contact (primarily vaginal or anal) with an infected person. Transmission to newborn at birth is also another method of transmission. Though the symptoms are not very noticeable, in women the symptoms may include; an unusual vaginal discharge, bleeding after intercourse, bleeding between menstrual periods, and abnormal pelvic pain. In men, the symptoms may include discharge from the penis, burning with urination and swollen and/or painful testicles.

Chlamydia can be easily treated and cured with antibiotics like tetracycline, doxycycline, and azithromycin. Because men and women infected with chlamydia often also have gonorrhea, treatment for gonorrhea is often provided as well. Vaginal Infections and Vaginitis Vulvovaginal candidiasis (VVC), sometimes referred to as candidal vaginitis, monilial infection, or vaginal yeast infection, is a common cause of vaginal irritation. It has been estimated that about 75% of all women will experience at least one episode of VVC during their lifetime.

VVC is caused by an overabundance or overgrowth of yeast cells (primarily Candida albicans) that normally colonize in the vagina. Several factors are associated with increased rates of VVC in women, including pregnancy, uncontrolled diabetes mellitus, and the use of oral contraceptives and antibiotics. Other factors that may increase the incidence of VVC include the use of douches, perfumed feminine hygiene sprays, and tight, poorly ventilated clothing and underwear. The most frequent symptoms of VVC in women include severe itching, burning and irritation of the vagina.

Painful urination and/or intercourse are common. Abnormal vaginal discharge may be minimal or not always present. If the discharge is present though, it is cottage-cheese-like’ in nature although it may vary from watery to thick in consistency. Male partners of women with VVC will not develop any symptoms of the infection. However, a transient rash and burning sensation of the penis have been reported after intercourse if condoms were not used. Treatment comes in the form of arious antifungal vaginal fungal creams (like clotrimazole and miconazole) which are available over the counter for use in the vagina.

Conclusion We think of these diseases and most of us are in the habit of saying that it will not affect us. This lab report has brought your attention to the fact that not all STDs are contracted through sexual intercourse but rather through the air we breathe if we are in proximity to an infected person. Though the only almost full proof method of not contacting any STD would be abstinence, the use of a condom correctly during sexual intercourse is just as effective. Another effective method is to have one sexual partner and know their history before they were with you.

Sexually Transmitted Diseases

Sexually Transmitted Diseases

Sexually transmitted diseases are infectious diseases that can be spread by sexual contact. Some can also be transmitted by non-sexual ways, but these make up a minority of the total number of cases. An estimated ten to twelve million Americans have sexually transmitted diseases. Sexually transmitted diseases in the United States affect both sexes, all races, and every economic stature. STD’s come from different sources. Some are epidemic like gonorrhea, infections of the urethra, genital herpes, and genital warts.

Some diseases are caused by a bacterium such as Chlamydia, and others are from protozoan or yeast. Many of these infections are transmitted largely by sexual contact with an infected person. The practice of anal and oral sex also lead to cases of anal and oral infections. Gonorrhea, syphilis, and chlamydial infections can also be transmitted from a pregnant woman to her infant, either in the uterus or during birth. Sexually transmitted diseases are very hard to control. Some public officials attribute the increase in many of these diseases to increasing sexual activity.

Others say the replacement of the condom with birth control pills and diaphragms might also increase the risk of STD’s. “Many STD’s are transmitted more efficiently from men to women than the reverse, perhaps because the vagina serves as a reservoir that prolongs exposure to infectious secretion (Handsfield 2)” The physical examination of patients with STD or at risk is a simple procedure. All patients require inspection of the entire skin surface. At a minimum they carefully inspect all skin surfaces that are uncovered or exposed during genital examination.

This includes the face, head, hands, lower arms, lower trunk, pubic area, thighs, mouth and throat. Also checked in men are the genitals and the pubic and inguinal regions, the penis, urethra, urethral bulb, and the scrotum are checked for tenderness and other abnormalities. “For homosexually active men, the anus and perineum are carefully inspected. The examination of women includes inspection of the pubis area, the external genitals, perineum and anus, speculum examination of the vaginal mucosa and cervix, and a bimanual pelvic examination (Handsfield 4).

A way to avoid STD’s and unwanted pregnancies is to use a condom. “A condom is a sheath worn over the penis during oral, anal, and vaginal sexual contact (Virginia Tech Health Services). ” Condoms can be made of latex rubber or animal membrane. Animal membrane condoms prevent pregnancy but have large enough pores for tiny HIV viruses to pass through. Latex condoms are much better in forming a barrier against HIV. Polyurethane condoms haven’t been fully tested, so people should avoid using them.

Do not use novelty condoms like the ones that glow in the dark, these are not FDA approved. Always check the expiration date. Never use a condom after the date stamped on the wrapper or on the seal. Do not use a condom that has been in a wallet for more than a month. Heat and pressure can damage it. Also, stay away from oil-based lubricants, like Vaseline, which can eat through the latex. And finally, do not open the packet with scissors or your teeth, the condom could rip. Nudge the condom away from the edge and gently tear the packet open.

Next to abstinence, which is having no sexual relations at all, condoms are the best protection against STD’s. When a condom is used correctly, they are about 90 percent effective in preventing pregnancy, and 95 percent effective when used with spermicide. Spermicide, also called Nonoxynol 9, has been found to be effective in killing the HIV virus in laboratory experiments when used at 5 percent strength. Spermicide immobilizes and kills sperm. It comes in jellies, creams, foams, suppositories, film, and as a coating on condoms. STD’s can also be avoided by remaining monogamous.

This means only having sex with one person whom only has sex with you. If you know that you are clean of all STD’s and that your partner is also clean, then you both can avoid STD’s by only being with each other. Chlamydia is a STD caused by the bacterium Chlamydia trachomatis. The bacterium is found in infected body fluids from the penis or vagina and it spreads through direct sexual contact and from mother to baby. Chlamydia is the most prevalent bacterial STD, about four million people will become infected with Chlamydia this year.

Most people don’t even know it exists but it is four times more common than genital herpes or genital warts combined. Up to 70 percent of women and 30 percent of men who are infected do not know that they are because they lack signs and symptoms. There are no symptoms for this disease so people are not aware that they have a problem until they develop complications. In women this includes pelvic inflammatory disease (PID), infertility, and dangerous complications during pregnancy and birth. In men the testicles become inflamed.

Some signs of Chlamydia for men and women are a discharge from the penis, vagina, or rectum, cramps in the lower abdomen, burning or itching around the opening of the penis, pain in the testicles, pain when urinating, unusual vaginal bleeding, and bleeding after sex. If a woman with Chlamydia is pregnant and she is not treated, her baby has a 50-50 chance of developing conjunctivitis, which is an inflammation of the eyes that threatens eyesight, and a 20 percent chance of pneumonia. Chlamydia can also lead to premature birth or low birth weight.

Chlamydia is the easiest STD to treat. Doctors can prescribe a single dose of an antibiotic called Azithromycin, or they can prescribe Doxycycline for 7 days. Either of these antibiotics will cure this disease within a week. Every year up to one million Americans develop genital warts, and as many as 50 percent of all men and women are now infected. Human Papilloma Virus (HPV) is the virus that causes genital warts. These warts grow on the genitals, in the urethra, in the anus, and rarely in the throat. They are soft to the touch and may look like miniature cauliflower florets.

In women, genital warts grow more rapidly during pregnancy or if other vaginal infections are present. “They often itch and if they are allowed to grow, in severe cases they can block the openings of the vagina, anus, or throat and become quite uncomfortable. (Handsfield 4)” HPV infection is spread from person to person through direct skin contact during vaginal, anal, or oral sex with someone who has genital warts. Babies can get the virus if their mothers have genital warts at the time of delivery. Signs of genital warts occur six weeks to eight months after contact with someone with HPV.

Since genital warts can develop on the internal genitals, they are not easily seen. Sometimes the infection doesn’t cause any warts and many people with HPV do not know that they have it. Freezing the warts with liquid nitrogen, applying certain chemicals, using laser therapy, and using electrical heat can easily treat genital warts. Even though the warts will be removed, some of the virus may still stay alive in the skin and cause more warts. This means that more than one treatment may be needed to get rid of all the warts.

The one thing not to do is use over the counter treatments for warts on sensitive genital skin. Genital warts can be avoided by being monogamous, by always using condoms, and by knowing the signs of HPV infection. Acquired Immune Deficiency Syndrome (AIDS) is the destruction of the immune system resulting from infection with the Human immunodficiency virus (HIV). AIDS is a gradual weakening of the immune system, which allows severe infections and cancers to grow. It eventually leads to death from one of these illnesses. It may take six to ten years until the HIV infection becomes AIDS.

This disease attacks the CD4 T-cell count, these are the major types of white blood cell lost during the HIV infection. The lower the person’s CD4 T-cell count, the more advanced the person is into the disease. Within one to three weeks after infection with HIV, most people experience general flu like symptoms like fever, headache, skin rash, tender lymph nodes, and malaise. These symptoms last for about one to two weeks. During this time HIV reproduces to very high concentrations, it circulates through the blood, and creates infections all throughout the body, especially in the lymph nodes.

The infected person’s CD4 T-cell count falls briefly but then returns close to normal and the person’s immune system responds to the infection and limits the spread of HIV. The next phase can last for up to ten years. The person stays healthy and his or her CD4 T cell level is between low and normal, which is 500 to 700 cells per mm3. HIV continues to spread and reproduce causing more destruction to the immune system. Eventually the immune system declines and the person’s T cell level drops dramatically from about 500 to 200 cells per mm3. Infections then spread but they are not yet life threatening.

Within the next couple of months or years the immune system is destroyed and serious illnesses set in. The infected person may have CD4 T-cell levels below 200 per mm3. Next comes a stage of ongoing weight loss and fatigue. The immune system fails and the T-cell count is below 50 per mm3, and death occurs within one to two years. HIV is most commonly spread by sexual contact with an infected person. The virus is present in the sexual secretions of men and women. HIV goes into the bloodstream of the uninfected person by getting into small abrasions or by sexual intercourse.

Sharing needles or syringes that contain the blood of an infected individual also spreads HIV. Transmission through blood transfusions is now very rare and it occurs in less than one person in every 100,000. HIV can be transmitted from an infected mother to her baby, either before or during childbirth or through breast-feeding. Only about 30 percent of babies born to HIV-infected mothers actually become infected. “The three anti-HIV drugs currently licensed by the U. S. Food and Drug Administration (FDA) are all RT inhibitors: AZT, ddl, and ddC. These drugs work as DNA-chain terminators.

Because the drug appears to be a normal nucleotide base (the building block for DNA), the RT enzyme mistakenly inserts the drug into the growing viral DNA chain. Once the drug is inserted, no additional DNA bases can be added (Encarta). ” These drugs are not a cure for the HIV infection, scientists originally wanted them to slow the progression of AIDS, and they have extended the life of the infected individual by about six months. Syphilis is an infection that can be life threatening if it is not treated. It is caused by a bacterium called Treponema pallidum.

This bacterium is found in sores and rashes that occur anywhere on the skin or inside the mouth or genitals. Syphilis is spread by sexual contact and from mother to baby during pregnancy. Without treatment the infection can lead to heart disease, nerve disorders, brain damage, mental disorders, blindness, and death. There are six symptoms that an infected person with syphilis may have. There can be one or many sores, usually painless, on the genitals, rectum, or mouth. Rashes anywhere on the body are another symptom. The rashes can be flat, scaly, round, or crater like.

One may also develop headaches, sore throats, swollen glands, and hair will fall out in big patches. There are four stages of syphilis. First, there is a development of a red, painless sore. Within one to six weeks it will go away on its own. Second, development of the rash and flu-like symptoms. These symptoms can be mild and come and go for over two years. Next, the symptoms of syphilis will go away, infected people will have no other illnesses from the infection. Stage four is late stage syphilis. The infection begins to damage the heart, brain nerves, bones and other parts of the body.

Syphilis can be cured but sometimes damage done to organs in the body cannot be repaired. Syphilis can be treated with antibiotics, mainly with penicillin. Other antibiotics can be prescribed if one is allergic to penicillin. This antibiotic kills the bacteria causing the infection. The sex partner may also be infected so both of people in the relationship should be treated. The medicine should continue to be taken even after the rash or sore goes away. Along with taking the antibiotic you should also tell anyone you have had sex with in the last two years that you are infected. Do not have sex again until your doctor gives an okay.

You should get rechecked to make sure you are cured and also get checked for HIV. Gonorrhea is a disease caused by a bacterium called Neiserria gonorrhoeae. The bacteria that cause gonorrhea are found in the vagina, penis, throat, rectum, and in the semen or vaginal fluids. Gonorrhea is spread through sexual contact and from mother to baby during delivery. It is the most commonly reported sexually transmitted disease in the United States. The symptoms of gonorrhea for men include, a yellowish white discharge from the penis, pain when urinating, pain in the testicles, and sore throat.

Women usually do not have symptoms. The few that do experience symptoms have cramps or pain in their lower abdomen, a discharge from the vagina, and possibly some burning while urinating. Symptoms can be noticed as early as two to seven days after having sex with an infected person, sometimes it can take as long as thirty days for symptoms to develop. The disease is diagnosed through tests done on penile or vaginal discharges to see if the bacterium is present. Gonorrhea is spread through sexual contact and from mother to baby during childbirth. Gonorrhea can be treated with antibiotics.

All strains of gonorrhea are curable, but this disease is becoming more and more resistant to many standard medications. Penicillin is one of the drugs that the bacterium is now resistant to. Presently the antibiotics ceftriaxone, cefixime, ciproloxacin, or ofloxacin are used. Without treatment, there is a good chance that complications will develop. “Women could develop pelvic inflammatory disease (PID), a painful condition that occurs when the infection spreads throughout the reproductive organs. PID can make women unable to have children or cause them to be at risk for ectopic pregnancy (Virginia Department of Health).

Men experience a swelling of the testicles and penis. Both men and women may develop arthritis, skin problems and other infections that will spread throughout the body. “All sexually active women under the age of 20, and those who have inflammation of the cervix should be tested, according to the Centers for Disease Control and Prevention (CDC). Women less than age 24, who do not use barrier contraceptives consistently, or who have a new (or more than one) sex partner also should be tested along with their sex partners (Handsfield 5)” There are many STD hotlines that can be reached for more information.

The National STD Hotline’s number is 800-227-8922. You can also call Health on Demand at (607) 737-4499. If you have been raped and you fear you might have contracted a STD you can call the Rape, Abuse and Incest National Network Hotline (RAINN) at 800-656-4673. All hospitals and doctor’s offices also carry information on STD’s. Always consult your physician if you think you could be in danger of having a STD. By writing this paper I realized that I was pretty nave about how big of a problem STD’s are. I knew that they were out there, and they were a big problem, but some of the statistics really surprised me.

Like 50 percent of all men and women have genital warts. After learning so much about these diseases and what they can do to you, I really think we should have a unit in class dealing with STD’s. I also think that the school should offer a STD course, and offer free condoms to students like some other schools have started to do. The usefulness of knowing all that I do about this topic can really help me out in the future. I will able to recognize whether something looks bad, and I also learned the best methods of protection. All in all, I am really happy that I chose to do this paper.
