Most common STD us physically sent sicknesses (STDs) have been available among humanity for quite a long time. In many regions of the planet, pervasiveness is still high regardless of advances in diagnosing and treating the contaminations.
Some of the challenges in curbing STD incidence include:
- The advent of sexual freedom, changing sexual attitudes and the use of oral contraceptives.
- Contraction of the infection while travelling to other countries. Historically, one of the main ways STDs were spread was through sexual contact with sailors who had picked up the infections during their voyages overseas.
- Microbial resistance to what were once effective treatments. For example, many of the bacteria that cause STDs are now resistant to the antibiotic penicillin, which was previously widely used with high success rates.
Some STDs are more common than others worldwide. Approximately two-thirds of all STDs worldwide affect people under the age of 25. One of them and the third is under 20 years old. Adolescent girls have a higher rate than boys, and girls are twice as likely to have an infection. Examples of some statistics of STDs in the USA in 2011 include:
The incidence rate of chlamydia infection per 100,000 people was 457.6, which is 8% higher than the 2010 figures. People with chlamydia may or may not have symptoms.
The rate of gonorrhea was 104.2 per 100,000 people, an increase of 4% in 2010. Affected people may or may not have symptoms.
For syphilis, the number in 2011 did not change compared to 2010 with a rate of 4.5 per 100,000 people.
The frequency of inherent syphilis was 8.5 per 100,000 live births, 7% lower than the 2010 rate.
The Centers for Disease Control and Prevention estimates that 110 million people in the USA were infected with STDs in 2008. Approximately 22.1 million people with STDs were between the ages of 15 and 24, and about a quarter of all adolescents are affected. And STD every year.
In 2009, about two-thirds of new infections diagnosed in women were in people under 25 and about half of the infections were in men under 25.
