Sexually Transmitted DiseasesSexually Transmitted Diseases (STDs) are very common in today's society. They pose a threat to humans because, when they cannot be cured, they can become an epidemic, like AIDS. Although STDs can affect people of all ages, young people – especially college students – between the ages of 19 and 25 are the most affected (American Social Health Association). There are three types of sexually transmitted diseases: bacterial, viral and parasitic. In this essay we will study a disease for each category, analyzing its causes, describing the symptoms and learning about the available treatments. We will also investigate whether or not there is a cure for the disease. Our research will focus on the following diseases: chlamydia, hepatitis B and pubic lice.

Additionally, when a woman becomes infected while pregnant, she can pass the disease to her baby. Since chlamydia is a disease transmitted during unprotected sexual intercourse, the more partners a person has, the greater the risk of contracting the infection. This statement is especially true for women under 25. But women are not the only victims of chlamydia. Men also suffer from chlamydia, especially when they have... half of the paper... ions for medical education and research. March 3, 2010. Web..MD Consult. "Pubic lice." See MD. January 1, 2010.
