Sexually transmitted diseases (STDs) are infections that individuals can get from having sex with someone who has the infection. The causes of STDs are bacteria, parasite,s and viruses. There are more than 20 types of STDs, including chlamydia, gonorrhea, genital herpes, HIV/AIDS, HPV, syphilis and trichomoniasis.
Most STDs affect both men and women, but in many cases the health problems they cause can be more severe for women. If a pregnant woman has an STD, it can cause serious health problems for the baby.
Correct usage of latex condoms greatly reduces, but does not completely eliminate, the risk of catching or spreading STDs. With nearly 19 new STD infections annually almost half of those are among young people ages 15 to 24. STDs affect men and women of all backgrounds and economic levels, and add an estimated $17 billion to the nation’s healthcare costs every year.
Despite the fact that STDs are extremely widespread, most people in the U.S. remain unaware of their consequences of all but the most prominent STD—HIV, the virus that causes AIDS.
The rate in this chart is specifically for that of chlamydia. Dallas County has 594 cases per 100,000—well above the Texas and U.S. rates. The Tarrant County rate is 448, which is slightly higher than the Texas rate of 435. Denton and Collin county rates are nearly identical at 227 and 226, respectively.
