STD epidemic is sweeping the US with cases of chlamydia reaching 'record levels' - while gonorrhea and syphilis are also on the rise

  • CDC report warns of STD epidemic rising across the United States
  • Chlamydia, gonorrhea and syphilis all increased for first time in 9 years
  • Total of 1.4 million chlamydia cases - highest number of annual cases of any condition ever reported to the CDC
  • Experts call for better diagnosis, treatment and prevention to stem rise 
A sexually transmitted diseases epidemic is sweeping the US, with cases on the rise as chlamydia infections reaches 'record levels', experts have warned.
Cases of chlamydia, gonorrhea and syphilis have all increased for the first time since 2006, according to the Centers for Disease Control and Prevention (CDC).
Chlamydia cases had dipped in 2013, but last year's total of more than 1.4 million — or 456 cases per 100,000 — was the highest number of annual cases of any condition ever reported to the CDC.
The chlamydia rate was up almost three per cent from 2013, new figures revealed.
'America's worsening STD epidemic is a clear call for better diagnosis, treatment, and prevention,' said the CDC's Dr Jonathan Mermin.

Experts have pointed the finger at dating apps, including Tinder, Happn and Grindr, warning they could trigger an 'explosion' in rates of sexually transmitted diseases. 
In May this year, The Rhode Island Department of Health revealed from 2013 to 2014, cases of syphilis rose by 79 per cent, gonorrhea by 30 per cent and HIV by almost 33 per cent. 
And in September this year, The AIDS Healthcare Foundation launched a new billboard campaign in Los Angeles, drawing users' attention to the risk of catching chlamydia and gonorrhea during casual sex among young adults.
The charity said a rise in STDs corresponds with the growing popularity of dating or 'hookup' mobile phone apps.
Whitney Engeran-Cordova, senior director, Public Health Division for AHF: said: 'Mobile dating apps are rapidly altering the sexual landscape by making casual sex as easily available as ordering a pizza.'
However, a CDC spokesman told Daily Mail Online: 'There is no single answer to explain why STDs are increasing this year.
These are complex diseases that can be impacted by a number of factors.'
He said increased STD screening, including more extragenital screening, may be increasing detection of chlamydia and gonorrhea infections, especially in men.
The spokesman added: 'We don't have any evidence showing a link between STDs and dating apps.
'Having anonymous partners though, can make it difficult to offer partner services, like expediated partner therapy, or conduct contact tracing for syphilis to interrupt the cycle of transmission.'
The CDC report revealed gonorrhea cases totaled 350,062, up five per cent from 2013, and the most contagious forms of syphilis jumped 15 per cent to 20,000 cases. 
As in previous years, the increase in syphilis was largely among gay and bisexual men.
Syphilis among these groups has been increasing since at least 2000.
In 2014, rates of syphilis increased among men who have sex with men, who account for 83 per cent of reported cases among men when the sex of the partner is known.
Also concerning is that more than half of men who have sex with men (51 per cent) diagnosed with syphilis in 2014 were also HIV-positive. 
Infection with syphilis can cause sores on the genitals, which make it easier to transmit and acquire HIV.
