Study Notes
Sexually Transmitted Infections (STIs)
- Chlamydia is caused by the bacterium Chlamydia trachomatis and can be transmitted through unprotected vaginal, anal, or oral sex.
- Chlamydia can infect the urethra, rectum, female reproductive tract, mouth, throat, or eyes.
- Treponema pallidum is the bacterium responsible for syphilis.
- Syphilis affects the skin and can be transmitted through direct contact with a syphilis sore.
- Herpes is a sexually transmitted infection caused by the herpes simplex virus.
- Genital herpes can be transmitted through contact with an infected area, even if there are no visible sores.
- Human papillomavirus (HPV) affects the skin and is the most common STI; there are over 100 different types.
- HPV is easily caught and you do not need to have penetrative sex to get it.
- Many people with HPV have no symptoms, and may not know they have an STI.
Other Concepts
- Family Planning: Refers to the ability of individuals and couples to anticipate and attain their desired number of children, and to determine the spacing and timing of their births.
- Gross Domestic Product (GDP): The monetary value of all finished goods and services made within a country during a specific period.
- Economic System: A system of production, distribution, exchange, and consumption of goods and services.
- Gross National Product (GNP): The total value of all the final goods and services made by a nation's economy in a specific time (usually a year).
- Inflation: A general increase in the prices of goods and services in an economy.
- Deflation: A decrease in the general price level of goods and services.
- Price Stability: Means that the general price level in an economy does not change much over time. Prices neither go up nor down; there is no significant degree of inflation or deflation.
- Finance: The management of money and includes activities such as investing, borrowing, lending, budgeting, saving, and forecasting.
- Productivity: Increases when more output is produced with the same amount of inputs.
- Efficiency: Refers to how much output can be produced with a given set of inputs.
- Market Equilibrium: The state in which market supply and demand balance each other, and as a result prices become stable. An over-supply of goods or services causes prices to go down, which results in higher demand, while an under-supply or shortage causes prices to rise.
Contraception Methods
- Calendar Method: Also called the calendar method. This method involves tracking your menstrual history to predict when you'll ovulate.
