The shadow pandemic: rising syphilis rates in the wake of coronavirus (COVID-19).

The coronavirus disease 2019 (COVID-19) aftermath left an alarming surge in syphilis cases, contradicting the previously stable trajectory of the infection. US Centers for Disease Control and Prevention also reported a 38% increase in primary and secondary syphilis in 2021 compared to 2019 in the United States, prompting a retrospective analysis at our tertiary care centre in New Delhi, India. There was a persistent linear rise, surpassing pre-COVID levels. Male clinic attendees, exhibit a pronounced increase, likely due to the influence of MSM. Online sexual activity during lockdowns and redirected healthcare resources have possibly contributed to this trend. Urgent measures include strengthened surveillance data collection and public health response, awareness promotion, and early, free treatment. The syphilis surge may signify a broader, undiagnosed STI pandemic, necessitating comprehensive intervention and surveillance.
