Got Chlamydia? Hundreds of Thousands are Undiagnosed

Got Chlamydia? Hundreds of Thousands not diagnosed  Lev Dolgachov/PhotoSpin

Hundreds of thousands of cases of chlamydia go undiagnosed each year, research by the Centers for Disease Control and Prevention suggests.

The study was conducted through the United States National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention.

Scientists' calculations were formulated by analyzing the information provided within the National Health and Nutrition Examination Survey (NHANES) from 2007 through 2012.

This study involved about 5,000 subjects from across American annually and included both children and adults.

Researchers found that 1.7 percent of men and women ages 14-39 have chlamydia, which works out to about 1.8 million infections each year in the United States.

There are 1.4 million cases reported to the CDC each year. As a reportable disease, all diagnoses of chlamydia are supposed to be reported to the CDC. That discrepancy signifies that as many as 400,000 cases of chlamydia not only go unreported, but likely go undiagnosed every year.

A major reason why chlamydia is so often undiagnosed is that it often produces no symptoms. Unlike other STDs which result in the appearance of symptoms within a matter of days after infection, chlamydia does not. And when symptoms do appear, they may be mild and resolve quickly.

Symptoms can include abnormal discharge from the penis or vagina, a burning sensation during urination, and pain or swelling in the testicles for men.

Along with the revelation of under-reported cases, they also found that young women are at a much greater risk of harboring chlamydia.

The investigators found that the chlamydia infection rate is highest among sexually active girls aged 14-19, at 6.4 percent, HealthDay News reported. The rate among sexually active boys aged 14-19 is 2.4 percent.

Among these female adolescents, chlamydia infection is nearly six times more common in African-Americans than in their white counterparts. The rate found among the African-American girls was 18.6 percent, while the teenage white girls had a much lower rate of 3.2 percent.

My parter a d I have been diagnosed for chlamydia 2 years ago before we got married. Then been diagnosed as well for UTI myself. Now i am unsure if we still have this infection. I am worried of not getting pregnant and cancer issues. Is there any possibility that it would come back? A month ago, i have been scratching my private part, lightly foul smell there is, yellowish/greenish discharge and pain when urinating. All these symptoms i felt before. And my partner's penis smells as well.

I am so worried. Help us please..
Thank you so much

Hi Anon

Thanks for you post! 

You are exhibiting symptoms of an infection. You absolutely need to be seen again and tested for infection and your husband should too. Refrain from sex until you know you are both infection free. 

Will you keep us posted?

Has no one ever been able to tell you why you have all these complications along with the resounding odor or smell? You are right... some doctors don't know and can't know everything. That's why sites like EmpowHER are so helpful. I'm going to do some searching and ask a couple of our sexual health doctors to see what they think it could be. You shouldn't have to live like this. That's just not right! Let's see what are moderators come back with as well. So sorry you have to go through this! It's not bad enough that you were raped, my heart goes out to you, but to have no one who can help you figure out what you have is not just not acceptable. Thank you for sharing your story! I'm sure it's not easy to share such personal information... But you are in a very safe place here at EmpowHER. That's why I created the site should you could share and be your own best advocate which is exactly what you're doing. Big Hugs! August 21, 2014 - 2:46pm

All I know is that after being raped, sorry, I started to smell, then got ulcers or cysts in my womb and every period is painful.

Smells really bad. I also got big dark spots that left dark pigmentation that scabs with a hole in the middle, so the spot scabs over peels off then turns black circle like black marks on my face. Doctors don't know everything, it would seem like I was making it up. I been checked for nearly all STD's and nothing was found. Early on I went out with a half african and white guy, brought up in africa and I got a infection something I am unsure of but they said if I had children my kids would get it.

These things are real, doctors do not know everything there is to know. Why do I smell like that - I remember the white male smelt weird and I assumed that was how they smelt - it was a bad smell like something raw and hotdogish, musty. I really thought that was what the what they smelt like and it was awful.

Then I started getting all these complications.

Hi Anon

I am so sorry to read about your rape - I hope you are receiving counselling and support. 

You absolutely need to get more medical care. Find out what kind of infection you were diagnosed with - find the name. Then you will know what is meant by your "kids will get it." This could mean HIV, herpes or genital warts/HPV (if you have an outbreak during pregnancy you may have to have a c-section to avoid passing HPV or herpes via a vaginal birth). 

Please go back to your doctor and ask for further testing. Ask to see your medical records and ask for any testing or diagnoses to be explained to you in a way you can understand - sometimes medical jargon can be difficult for us to comprehend. 

Will you keep us updated, Anon?
