Sexually transmitted disease in the context of "Genital herpes"

Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The public can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of health takes into account physical, psychological, and social well-being, among other factors.

Public health is an interdisciplinary field. For example, epidemiology, biostatistics, social sciences and management of health services are all relevant. Other important sub-fields include environmental health, community health, behavioral health, health economics, public policy, mental health, health education, health politics, occupational safety, disability, oral health, gender issues in health, and sexual and reproductive health. Public health, together with primary care, secondary care, and tertiary care, is part of a country's overall healthcare system. Public health is implemented through the surveillance of cases and health indicators, and through the promotion of healthy behaviors. Common public health initiatives include promotion of hand-washing and breastfeeding, delivery of vaccinations, promoting ventilation and improved air quality both indoors and outdoors, suicide prevention, smoking cessation, obesity education, increasing healthcare accessibility and distribution of condoms to control the spread of sexually transmitted diseases.

Oral sex, sometimes referred to as oral intercourse, is sexual activity involving the stimulation of the genitalia of a person by another person using the mouth (including the lips, tongue, or teeth). Cunnilingus is oral sex performed on the vulva while fellatio is oral sex performed on the penis. Anilingus, another form of oral sex, is oral stimulation of the anus.

Oral sex may be performed as foreplay to incite sexual arousal before other sexual activities (such as vaginal or anal intercourse), or as an erotic and physically intimate act in its own right. Like most forms of sexual activity, oral sex can pose a risk for contracting sexually transmitted infections (STIs). However, the transmission risk for oral sex, especially HIV transmission, is significantly lower than for vaginal or anal sex.

A condom is a sheath-shaped barrier device used during sexual intercourse to reduce the probability of pregnancy or a sexually transmitted infection (STI). There are both external condoms, also called male condoms, and internal (female) condoms.

The external condom is rolled onto an erect penis before intercourse and works by forming a physical barrier which limits skin-to-skin contact, exposure to fluids, and blocks semen from entering the body of a sexual partner. External condoms are typically made from latex and, less commonly, from polyurethane, polyisoprene, or lamb intestine. External condoms have the advantages of ease of use, ease of access, and few side effects. Individuals with latex allergy should use condoms made from a material other than latex, such as polyurethane. Internal condoms are typically made from polyurethane and may be used multiple times.

Reproductive rights are legal rights and freedoms relating to reproduction and reproductive health that vary amongst countries around the world. The World Health Organization defines reproductive rights:

Reproductive rights may include some or all of: right to abortion; birth control; freedom from coerced sterilization and contraception; the right to reproduce and start a family, the right to access good-quality reproductive healthcare; and the right to family planning in order to make free and informed reproductive choices. Reproductive rights may also include the right to receive education about sexually transmitted infections and other aspects of sexuality, right to menstrual health and protection from practices such as female genital mutilation (FGM). Protections from mistreatment during pregnancy, labor, delivery, and postpartum are also part of the reproductive rights framework, which calls into questions practices like shackling pregnant people in correctional facilities. Reproductive Rights are connected to broader social conditions and determinants, reproductive freedom requires not only legal rights but affordable healthcare, safe living environments, as well, as economic stability.

In mammals and other animals, the vagina (pl.: vaginas or vaginae) is the elastic, muscular reproductive organ of the female genital tract. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The vaginal introitus is normally partly covered by a thin layer of mucosal tissue called the hymen. The vagina allows for copulation and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle.

To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals. This increase in moisture provides vaginal lubrication, which reduces friction. The texture of the vaginal walls creates friction for the penis during sexual intercourse and stimulates it toward ejaculation, enabling fertilization. Along with pleasure and bonding, women's sexual behavior with other people can result in sexually transmitted infections (STIs), the risk of which can be reduced by recommended safe sex practices. Other health issues may also affect the human vagina.

Cunnilingus is an oral sex act consisting of the stimulation of a vulva by using the tongue and lips. The clitoris is the most sexually sensitive part of the vulva, and its stimulation may result in a woman becoming sexually aroused or achieving orgasm.

Cunnilingus can be sexually arousing for participants and may be performed by a sexual partner as foreplay to incite sexual arousal before other sexual activities (such as vaginal or anal intercourse) or as an erotic and physically intimate act on its own. Cunnilingus can be a risk for contracting sexually transmitted infections (STIs), but the transmission risk from oral sex, especially of HIV, is significantly lower than for vaginal or anal sex.

Coitus interruptus, also known as withdrawal, pulling out or the pull-out method, is an act of birth control during sexual intercourse, whereby the penis is withdrawn from a vagina prior to ejaculation so that the ejaculate (semen) may be directed away in an effort to avoid insemination.

This method was used by an estimated 38 million couples worldwide in 1991. Coitus interruptus does not protect against sexually transmitted infections (STIs).
