Most new cases in the United States (60%) occur in men who have sex with men; and in this population 20% of syphilis cases were due to oral sex alone. [3] [36] Syphilis can be transmitted by blood products, but the risk is low due to screening of donated blood in many countries. [3] The risk of transmission from sharing needles appears to be ...
With nontreponemal tests, false-positive reactions can occur for a large number of reasons, the most common of which is other infections, both viral and bacterial. Additionally these tests may show false-negative when the patient's antibody titer is very high due to a hook effect (also called a prozone effect).
Although it had some false positive results, it was a major advance in the detection and prevention of syphilis. [citation needed] By allowing testing before the acute symptoms of the disease had developed, this test allowed the prevention of transmission of syphilis to others, even though it did not provide a cure for those infected.
A staggering 207,000 syphilis cases were reported in the US in 2022 — an 80% increase since 2018. Syphilis cases soar to highest level in 70 years — CDC sounds alarm over ‘unacceptable’ crisis

For primary syphilis, TPPA has a sensitivity of 85% to 100%, and a specificity of 98% to 100%. [2] In secondary and late-latent syphilis, TPPA has a sensitivity of 98% to 100%. [2] Antibodies against other treponemal organisms, such as the T. pallidum subspecies endemicum, pertenue, or carateum, can cause false positive
A new proven protocol in which doxycycline is used to prevent sexually transmitted infections — called doxyPEP — has been an apparent sleeper hit among gay and bisexual men.
The MHA-TP is used to confirm a syphilis infection after another method tests positive for the syphilis bacteria. The MHA-TP test detects antibodies to the bacteria that cause syphilis and can be used to detect syphilis in all stages, except during the first 3 to 4 weeks. This test is not done on spinal fluid.
