Some STDs can spread through the use of unsterilized drug needles, from mother to infant during childbirth or breast-feeding, and blood transfusions. The genital areas are generally moist and warm environments, ideal for the growth of yeasts, viruses, and bacteria.
People can transmit microorganisms that inhabit the skin or mucous membranes of the genitals. Infectious organisms can also move between people in semen, vaginal secretions, or blood during sexual intercourse. Individuals pass on STDs more easily when they are not using contraceptive devices, such as condoms, dams, and sanitizing sex toys. Some infections can transmit through sexual contact but are not classed as STDs.
For example, meningitis can be passed on during sexual contact, but people can acquire a meningitis infection for other reasons. It is therefore not classed as an STD. People between the ages of 15 and 24 years acquire half of all new STDsand 1 in 4 sexually active adolescent females has an STD.
However, STD rates among seniors are increasing.
This bacterium only infects humans. Chlamydia is the most common infectious cause of genital and eye diseases globally.
It is also the most common bacterial STD.
According to the Centers for Disease Control and Prevention CDCinnearly 3 percent of girls aged 15 to 19 years had chlamydia. Women with chlamydia do not usually show symptoms. Any symptoms are usually non-specific and may include:. Chancroid is also known as soft chancre and ulcus molle. It is a bacterial infection caused by called streptobacillus Haemophilus ducreyi.
The infection causes painful sores on the genitals and is only spread through sexual contact. This infection is more common in developing nations, especially among commercial sex workers and some lower socioeconomic groups. This is due to the lack of access to healthcare services, the stigma attached to seeking help, a lack of sufficient sexual health education, and other factors. Injust 11 cases of chancroid were reported in the United States. Within 1 day to 2 weeks of acquiring the infection, the patient develops a bump that turns into an ulcer within a day.
It will be very painful and may have well-defined, undermined borders and a yellowish-gray material at its base.
If the base of the ulcer is grazed, it will typically bleed. In some cases, the lymph nodes swell and become painful. Women often have at least four ulcers, while men usually have just one.
Males tend to have fewer and less severe symptoms. The ulcers typically appear at the groove at the back of the glans List all sexually transmitted infections in uncircumcised males, or, in females, on the labia minora or fourchette.
Chancroid is treated with a 7-day course of erythromycin, a single
List all sexually transmitted infections dose of azithromycin, or a single dose of ceftriaxone. Pubic lice manifestations are primarily spread through sexual contact.
Pets do not play any part in the transmission of human lice. The lice attach to the pubic hair, and may also be sometimes found in the armpits, mustache, beard, eyelashes, and eyebrows. They feed on human blood. The virus affects the skin, cervix, genitals, and some other parts of the body.
There are two types:. Herpes is a chronic condition. A significant number of individuals with herpes never show symptoms and do not know about their herpes status.
HSV is easily transmissible from human to human through direct contact. Most commonly, transmission of type 2 HSV occurs through vaginal, oral, or anal sex. Type 1 is more commonly List all sexually transmitted infections from shared straws, utensils, and surfaces. Also, red blisters may occur on the external genital area, rectum, thighs, and buttocks.
These can be painful, especially if they burst and leave ulcers. It is transmitted through contact with infected semen, blood, and other bodily fluids. HBV is passed on in the following ways:. The liver swells, and an individual can experience serious liver damage as a result of HBV.
This can eventually lead to cancerand the disease can sometimes become chronic. Blood donation centers always check to make sure that any donors do not have hepatitis B. Trichomoniasis is a common STD that can affect both sexes. However, women are more likely to experience symptoms. The infection is caused by a single-celled protozoan parasite, Trichomonas vaginalis. For women, the vagina is the most common site of infection, while for men it is the urethra. Transmission may occur either by sexual intercourse or vulva-to-vulva contact.
While women may acquire the infection from either male or female sexual partners, men nearly always become infected from having sex with women. A woman with trichomoniasis is more likely to acquire HIV once to the virus. Human immunodeficiency virus HIV attacks the immune system, leaving its host much more vulnerable to infections and diseases.
If the "List all sexually transmitted infections" is left untreated, the susceptibility to infection worsens. HIV can be found in semen, blood, breast milk, and vaginal and rectal fluids. HIV can be transmitted through blood-to-blood contact, sexual contact, breast-feeding, childbirth, List all sexually transmitted infections sharing of equipment to inject drugs, such as needles and syringes, and, in rare instances, blood transfusions. With treatment, the amount of the virus present within the body can be reduced to an undetectable level.
This means the amount of HIV virus within the blood is at such low levels that it cannot be detected in blood tests. It also means that HIV cannot be transmitted to other people.
A person with undetectable HIV must continue to take their treatment as normal, as the virus is being managed, not cured. However, modern medicine means that HIV need not reduce life expectancy. Human papillomavirus is a name for a group of viruses that affect the skin and mucous membranes, such as the throat, cervix, anus, and mouth. There are over types of HPVof which, about 40 can affect the genital areas.

The majority of individuals with HPV have no symptoms and are unaware. HPV is so common in the U. HPV is most commonly transmitted through vaginal or anal sex, oral sex, and genital-to-genital contact. People with an HPV virus but no signs and symptoms can still infect others.

There are some prescription medicines that will eventually get rid of the growths. Scabies is a contagious skin condition caused by Sarcoptes scabieia tiny mite. They burrow into the skin and lay their eggs. A person with scabies develops a skin rash and experiences intense itchiness.
People with scabies are often unaware of their condition for several weeks after initial infection, which means scabies infestations spread rapidly. The cause of scabies is unknown, although some believe poor living conditions and a lack of personal hygiene are linked to the List all sexually transmitted infections. However, there is no scientific proof of this. Scabies is most commonly transmitted through close body contact, such as holding hands for a long time or sexual intercourse.
Hugging or simply shaking hands with a person who has scabies is unlikely to lead to transmission. The scabies mite cannot jump or fly.
However, it can survive for 1 to 2 days after leaving the human body. This means that sharing clothes List all sexually transmitted infections bedding with a person who has scabies increases the risk of infection.
However, prolonged physical contact, as is likely to occur during sexual intercourse, is the most common route of transmission. Less commonly, the rash may appear on the buttocks, ankles, armpits, genitalia, groin, scalp, neck, face, head, shoulders, waist, soles of the feet, lower leg, and knees.
