When calculating the number of prevalent and incident infections, only those infections that were sexually transmitted were counted,” said the CDC fact sheet. “In general, CDC estimated the total number of infections in the calendar year, rather than the number of individuals with infection, since one person can have more than one STI at a given time (e.g., HPV and chlamydia) or more than one episode of a single STI (e.g., repeat chlamydia infection).” Examples of sexually transmitted infections include:
The most frequently encountered sexually transmitted infection in the United States in 2008 was human papillomavirus (HPV), which caused 14,100,000 estimated infections that year.
After HPV, in order of its consequences, according to the study, new STIs in the U.S. in 2008 included 2,860,000 new Chlamydia infections; 1,090,000 new Trichomoniasis infections; 820,000 new Gonorrhea infections; 776,000 new Herpes Simplex Virus Type 2 (HSV-2) infections; 55,400 new syphilis infections; 41,400 new HIV infections; and 19,000 new Hepatitis B infections.
The total of 110,197,000 existing STIs in the United States in 2008 included 79,100,000 HPV infections, 24,100,000 HSV-2 infections; 3,710,000 Trichomoniasis infections; 1,579,000 Chlamydia infections; 908,000 HIV infections; 422,000 Hepatitis B infections; 270,000 Gonorrhea infections; and 117,000 Syphilis infections. Each year, there are almost 3 million new cases of chlamydia, many of which are in adolescents and young adults. There is disproportionate screening done for Chlamydia. Â Â Over 14 million people acquire HPV each year, and by age 50, at least 80 percent of women will have acquired genital HPV infection. Most people with HPV do not develop symptoms.
Gonorrhea reported rates wereÂ low in previous studies ,cases increased slightly from last year and more than 300,000 cases were reported in 2010 ..in 2013 Gonorrhea 333,004 Cases are reported.Â CDC reports that Â if the pregnant mother acquire Â gonorrhea or already have it, there is a 28% chance that her baby will have gonococcal ophthalmia neonatorum, which affects the cornea causing Â ulceration and Â corneal perforation
Chlamydia case reports have been increasing gradually over the last two decades, and in 2010, 1.3 million chlamydia cases were reported.. 6.8% of girls aged 14 to 19 years have Chlamydia today. While in 2013 CDC reports 1,401,906 cases.
The overall syphilis rate decreased for the first time in last decade, and is down 1.6 percent since 2009. However, the rate among young black men has increased dramatically over the past five years (134 percent). Other CDC data also show a significant increase in syphilis among young black men who have sex with men (MSM), suggesting that new infections among MSM are driving the increase in young black men. The finding is particularly concerning as there has also been a sharp increase in HIV infections among this population. CDC in 2013 reports an increase of 10% since 2012
Chancroid also called ulcus molle. The average prevalence in the US, UK, Australia, France and Canada is approximately 1 case in every 2 million people. It is a risk factor for contracting HIV
, due to their shared-risk exposure; also, one infection facilitates the transmission of the other.
These infective organisms are killing the reproductive years of female making them infertile according to few studies published. Still birth, premature birth and neonatal sepsis all causing extra trauma to families and economics too Safe sex with consistent condom use provides considerable protection against the acquisition of many STDs. There is Â statistically significant reduction of risk against HIV, chlamydia, gonorrhea, herpes, and syphilis.
