Syphilis Cases Surge in Argentina: Experts Warn of Rising Infection Rates Among Young Adults
Syphilis cases are surging across Argentina, prompting health specialists and provincial legislatures to update prevention policies and widen testing access.
- National health authorities recorded 46,799 syphilis cases in 2025, marking a 27% increase from 2024.
- Young adults aged 15 to 39 account for 76% of total notifications, with the highest rate seen among those aged 20 to 24.
- Experts emphasize that regular blood tests and barrier methods remain vital because early infections frequently present without noticeable symptoms.
Record infections in 2025
According to data from the Ministerio de Salud de la Nación, Argentina registered 46,799 syphilis cases in 2025, yielding a rate of 117.2 per 100,000 inhabitants. Diario El Norte – San Nicolás reported that this figure represents the highest annual tally since the statistical series began in 2011. The 2025 total reflects a roughly 27% increase compared to the 36,917 cases reported in 2024.
Additional figures from 25 Digital indicate that the average number of infections grew by 71% between 2024 and 2026, consolidating an upward trajectory that accelerated following the pre-pandemic period.
Impact on young adults
Specialists note that while the bacterial infection can affect individuals of any age, young people bear the heaviest burden. Official 2025 records show that 76% of all notifications occurred in individuals between 15 and 39 years old. Cadena 3 Argentina reported that the highest incidence rate occurred among those aged 20 to 24, reaching 290.6 cases per 100,000 inhabitants.
“Todas las edades pueden verse afectadas, porque tiene mucho que ver con las conductas de riesgo. Pero estadísticamente vemos que las personas jóvenes son las más afectadas, aproximadamente entre los 15 y los 35 años,” explained Ana Laura Arias, a gynecologist at Hospital Durand and Hospital Alemán, told Cadena 3 Argentina.
La sífilis puede presentarse sin síntomas visibles
A primary challenge in controlling the disease is its capacity to remain asymptomatic during certain phases. In its initial stage, the infection typically manifests as a painless sore or ulcer called a chancro at the site of sexual contact, which can easily go unnoticed.
“Muchas personas se preguntan cómo pueden tener sífilis si se sienten bien. Justamente, la infección puede atravesar etapas asintomáticas y pasar inadvertida si no se realizan estudios específicos,” Arias told Diario El Norte – San Nicolás.
If left untreated, the infection can progress to cause skin rashes, mouth lesions, and systemic complications affecting the central nervous system or internal organs. Regular blood testing during routine medical checkups remains essential for early diagnosis.
Provincial legislative updates and prevention
In response to the epidemiological trend, provincial authorities are adjusting sanitary measures. NoticiasNet reported that the Río Negro Legislature approved a set of projects in second reading to update preventive frameworks and expand community-based testing in hospitals and public spaces.
“Cuando empezamos a ver los números del incremento de la sífilis, entendimos que era realmente preocupante. Nos dimos cuenta de que estaba sucediendo algo que tenía que también ser visibilizado,” said Maricel Cévoli, a provincial legislator for Juntos Somos Río Negro, told Radio Noticias.
Complementing these legislative actions, the government of Río Negro expanded the free distribution of condoms through the 42 delegations of the Instituto Provincial del Seguro de Salud in coordination with the provincial laboratory PROFARSE, Diario Neuquino reported.
“Cuando la salud sexual se ve afectada y el contexto es adverso, lo primero que refuerza un Estado eficiente es la prevención,” said Ivana Porro, president of the insurance institute.
Medical specialists emphasize that while penicillin remains an effective and straightforward cure for the bacterial infection across all stages, consistent barrier protection, routine serological screening, and partner notification are critical to interrupting transmission chains.
