Frequently asked questions

Is Neurosyphilis always sexually transmitted?

Not necessarily. Some conditions in this directory are STIs, while others are genital or reproductive health conditions that may be associated with sexual activity or have other causes. The page explains the distinction.

Can symptoms appear without an infection?

Yes. Skin irritation, anatomical variation, inflammation and non-infectious conditions can cause similar symptoms. Testing and examination are needed before assuming an STI.

When should I seek medical advice?

Seek prompt advice for new sores, discharge, pelvic or testicular pain, painful urination, fever or symptoms that worry you. Early assessment can prevent complications and clarify the cause.

Should my partner be involved?

For many STIs, partner evaluation may be recommended to prevent reinfection and support treatment. The need depends on the condition, timing and results.
