Costa Rica Strengthens Yellow Fever Prevention Efforts Amid Regional Surge
Ministry of Health initiates targeted vaccination campaign and introduces digital vaccination certificates to combat yellow fever threat.
Costa Rica's Ministry of Health announced enhanced measures over the weekend to address the ongoing threat of yellow fever in the Americas.
During a press conference on March 9, officials reported a concerning rise in yellow fever cases regionally and detailed a vaccination initiative particularly aimed at border areas, along with the introduction of a digital vaccination card system.
As of 2024, the Americas recorded 61 confirmed yellow fever cases, with the numbers rising sharply in 2025, totaling 14 cases in just the first four weeks.
This represents a shift in the disease's geographic distribution, as historically, yellow fever was primarily reported in rural Amazonian regions.
More recently, cases have begun appearing in urban environments, heightening the risk of cross-border transmission, including implications for Costa Rica.
Although Costa Rica has not reported any local yellow fever cases, its geographical position and significant travel influx necessitate precautionary measures.
Yellow fever, transmitted by mosquitoes, can manifest as mild illness but also lead to serious complications.
Thus, prevention through vaccination is vital.
In response, the Ministry is launching a vaccination campaign targeting border areas, which are frequented by travelers and populations vulnerable to the virus.
While specific details of the campaign are still being finalized, officials indicated that it would prioritize individuals coming into contact with delegations from regions with high yellow fever risk.
The yellow fever vaccine is known for its efficacy, requiring only one dose that becomes effective after ten days and confers lifelong immunity.
Furthermore, effective March 11, 2025, Costa Rica will implement new entry requirements for travelers.
Those who have visited any of the 13 South American countries identified as having yellow fever risk—such as Brazil or Venezuela—or any African nation, will be required to present a valid vaccination certificate upon re-entry into Costa Rica.
This regulation was established late last year and is now taking effect.
To facilitate proof of vaccination, the Ministry has introduced a digital yellow fever vaccination card system.
This new system allows individuals to digitize their vaccination status, whether their paper certificates are current, expired, or issued overseas.
The process is straightforward: individuals will visit their local Health Governing Area, receive a username and password, and then be able to download their vaccination certificate in PDF or QR code format.
Dr. Mary Munive Angermüller, Costa Rica’s Minister of Health, emphasized the importance of these measures, stating that the digital card responds to modern needs for rapid verification and reduces the risks associated with lost paperwork.
The initiative aims to enhance the travel experience while ensuring public health safety.
Given Costa Rica's status as a Central American travel hub, the Ministry's proactive approach incorporates rigorous vaccination initiatives coupled with updated travel regulations and a digital verification system.
This strategy aims to mitigate the risk posed by yellow fever as it approaches urban areas in neighboring countries.
Residents near the borders may soon have access to free vaccinations, while travelers are encouraged to verify their vaccination status before embarking on international journeys.
