Painless syphilis sores often stay hidden, prompting call for yearly screening

Public health messaging on sexually transmitted infections stresses that the earliest signs of syphilis are easy to miss, largely because they usually arrive without pain. That quiet onset means infected persons can live with the condition for an extended period before they recognise that anything is wrong.

For women, a first sore may sit inside the vagina, where it cannot be seen without a deliberate examination. The sore can therefore be present even when outward appearance seems normal, which delays both self-detection and conversation with a clinician.

Men may develop a sore that is visible yet still free of sharp discomfort. Because it does not hurt, some individuals brush it aside as a minor skin issue rather than a reason to visit a health facility, even though such painless sores are among the first clues that syphilis could be present.

If the infection is not treated while still in an early phase, it can move into more advanced stages. Later on, people might notice rashes or other skin changes that look like ordinary dermatology complaints, which further obscures the link to an underlying sexually transmitted infection.

Against that background, the guidance is to make screening routine. Anyone who is sexually active should arrange a blood test for syphilis at least once every twelve months and should also keep annual appointments with a doctor for a full medical review. Pairing laboratory testing with a complete physical examination improves the chance of catching syphilis early, before illness moves into those later stages marked by rashes and other signs that may not look out of the ordinary.
