Syphilis in the post-Covid-19 pandemic world.

Syphilis, an ancient malady, remains clinically relevant. Recent increases in syphilis cases, especially congenital syphilis, should increase the clinician's index of suspicion when presented with one of the protean clinical syndromes associated with syphilis. Diagnosis and monitoring of response to treatment remain reliant on testing modalities with varying degrees of sensitivity and specificity, requiring clinical discernment. Penicillin remains the recommended treatment in most syphilis cases. New treatment options may be available soon.
