STI (Sexually Transmitted Infection) and STD (Sexually Transmitted Disease) are pretty much the same thing. STI is a more recent term. STDs are (though distinctions aren't always clear) STIs that have begun showing symptoms. People can get an STI that never shows symptoms. Once it shows symptoms it's then called an STD. So when first infected I guess all sexually transmitted maladys are STIs but later may become STDs.
Clamedia often shows no symptoms and so would more likely be an STI.
Chlamydia is not the most dangerous STI.
Chlamydia is an STD caused by the bacteria Chlamydia trachomatis. Other STDs do not cause, turn into, or lead to chlamydia.
Chlamydia is the #1 bacterial STI in the US.
Chlamydia psittaci is a different bacteria from the one that causes the STD known as chlamydia. That infection is caused by Chlamydia trachomatis. The tests for chlamydia are built to avoid cross-reaction with Chlamydia psittaci.
Chlamydia is not a disease that has stages. Syphilis is the STD with distinct stages.
Chlamydia is the most common bacterial STD in the US, and the most common reportable STD. You should know that not all STDs are reportable, so the CDC doesn't get direct reports about HPV or trichomonas.
You can't get chlamydia that way. Chlamydia is transmitted by oral, anal or vaginal sex; by genital-genital contact; or from an infected woman to her child during vaginal birth.
Sex. It is an STD.
"STD" describes how you get chlamydia. It is not a descriptor of whether or not it's curable.
Chlamydia is a sexually transmitted infection (STI) that can cause frequent urination.
Trachomatis is not the same as trichomonas. Chlamydia trachomatis is a bacterial STD, and trichomonas vaginalis is a protozoal STD.
Chlamydia trachomatis, the bacterium that causes the STD known as chlamydia, does not affect any animal other than humans. Other types of chlamydia, such as Chlamydia psittaci, affect animals.
