The allure of Costa Rica continues to draw thousands of international visitors each month, prompting many to contemplate the duration of their stay in this picturesque Central American nation. However, authorities are now addressing the growing trend of "perpetual tourism," while health officials are monitoring and advising on the presence of mosquito-transmitted diseases in 2025.

According to a report by the Tico Times on March 2, 2025, Costa Rica's government is taking steps to curb the practice of "perpetual tourism." This involves tourists extending their stays indefinitely by making brief border runs to neighboring countries such as Nicaragua, Ecuador, and Panama to reset their tourist visas. To combat this unsanctioned activity, the government intends to introduce legislation that could impose monthly financial penalties or even lead to re-entry bans for those found to be engaging in this practice. This move signals a firmer stance on immigration regulations and aims to ensure that visitors adhere to the intended limits of their tourist visas.

Meanwhile, the U.S. Embassy in Costa Rica is actively seeking to connect with American citizens residing and traveling within the country. The Embassy is particularly interested in hearing about their experiences related to safety and security. As part of their outreach efforts, they encourage U.S. citizens to enroll in the Smart Traveler Enrollment Program (STEP). This service provides digital alerts on safety issues and facilitates the Embassy's ability to locate and assist citizens in case of emergencies.

In other news affecting visitors, the Costa Rica Health Department has issued updates regarding the prevalence of mosquito-borne diseases in the country. Their Boletín Epidemiológico N°7 confirms the presence of Chikungunya, Dengue, Malaria, and Zika virus infections in 2025.

As of late February 2025, the following cases have been reported:

Chikungunya: Three cases have been confirmed, a significant decrease compared to the approximately 405 cases reported in 2024.
Dengue: Over 1,200 cases have been reported in 2025, a substantial drop from the roughly 31,200 cases recorded in the previous year.
Malaria: Six cases of locally acquired malaria have been confirmed. In 2024, there were 232 such cases.
Zika: Five cases have been reported in 2025, down from the 32 cases reported in 2024.

While the numbers for these diseases appear lower in the early part of 2025 compared to the entirety of 2024, health officials continue to advise caution and preventative measures. The U.S. Centers for Disease Control and Prevention (CDC) highlights that only one U.S. Food and Drug Administration (FDA)-approved Chikungunya vaccine is currently available, typically at travel clinics and pharmacies. Therefore, the CDC recommends that travelers consult with a healthcare provider at least a month before their trip to discuss necessary vaccinations and other preventative strategies.

Given the ongoing risk of mosquito-borne illnesses, visitors are strongly encouraged to take precautions to avoid mosquito bites. These measures include using insect repellent, wearing long-sleeved shirts and pants, staying in air-conditioned or screened accommodations, and eliminating sources of standing water where mosquitoes can breed. Whether enjoying Costa Rica's stunning beaches or exploring its lush mountainous regions, vigilance against mosquito bites remains a crucial aspect of ensuring a healthy and enjoyable trip in 2025.
