Final answer:
Both gonorrhea and chlamydia can present with genital discharge and painful urination, but are often asymptomatic. Syphilis progresses through three stages: primary with a painless chancre, secondary with skin rashes, and tertiary with potential systemic damage. Gonorrhea often goes undiagnosed due to lack of symptoms, highlighting the importance of routine STI screening.
Step-by-step explanation:
Understanding Sexually Transmitted Infections (STIs)
Both gonorrhea and chlamydia have similar symptoms which can include genital discharge and painful urination. However, many cases are asymptomatic, particularly in females, leading to undiagnosed and untreated infections that can result in complications like pelvic inflammatory disease (PID).
Syphilis is characterized by three progressive stages: primary, secondary, and tertiary. Primary syphilis presents with a painless chancre, secondary includes skin rashes and mucous membrane lesions, while tertiary syphilis can cause serious systemic damage including neurological and cardiovascular impacts.
People infected with gonorrhea often have no symptoms. As a resut, routine screening by healthcare professionals is crucial, especially for sexually active females under 25 and those with new or multiple sex partners. If detected, gonorrhea can usually be cured with a combination of antibiotics.
