Correct Answer is C
Explanation
Choice A reason: Chlamydia is not the least common of all the major sexually transmitted diseases. In fact, it is the most common bacterial STD in the world, affecting about 131 million people each year. ¹ Therefore, this statement is false and does not need to be emphasized.
Choice B reason: Good handwashing technique is not the best way to prevent chlamydial infections. Chlamydia is spread through sexual contact, not through casual contact or hygiene. The best way to prevent chlamydial infections is to practice safe sex, such as using condoms, limiting the number of partners, and getting tested regularly. Therefore, this statement is misleading and does not need to be emphasized.
Choice C reason: Most people infected with chlamydia are unaware that they are infected. This is because chlamydia often has no symptoms, or the symptoms are mild and easily ignored. This can lead to serious complications, such as pelvic inflammatory disease, infertility, ectopic pregnancy, and increased risk of HIV. Therefore, this statement is true and needs to be emphasized.
Choice D reason: Burning and pain with urination is a frequent symptom of chlamydial infections. However, this symptom is not specific to chlamydia, as it can also occur with other STDs or urinary tract infections. Moreover, not all people with chlamydia experience this symptom, especially women. Therefore, this statement is not very informative and does not need to be emphasized.
