In a shocking turn of events, a family vacation to Costa Rica has led to a serious health scare after twelve members fell ill following a visit to the infamous Venado Caves. This incident has raised alarms about the potential health risks associated with exploring bat caves, particularly for those unaware of the dangers lurking within.
Understanding histoplasmosis and its risks
Histoplasmosis is a fungal infection primarily affecting the lungs, caused by the Histoplasma organism, which thrives in environments contaminated with bird or bat droppings. The Venado Caves, a popular tourist destination, have been linked to previous outbreaks, including a notable one in 1998-1999 that affected over 50 individuals.
Symptoms of histoplasmosis can often mimic other illnesses, making it a challenge to diagnose. In this recent case, family members reported headaches, malaise, fever, and respiratory issues, leading to confusion and misdiagnosis in some instances.
The family’s experience and health response
The family, which spans across Georgia, Texas, and Washington, visited the caves between December 21 and 28, 2024. After returning home, they began experiencing symptoms 8 to 19 days post-exposure. One adult even required hospitalization due to abnormal chest radiography, initially raising concerns about lung cancer.
Fortunately, all affected individuals recovered within 28 days, but the incident has sparked a significant health alert.
Health authorities take action
In response to this outbreak, the Centers for Disease Control and Prevention (CDC) has taken proactive measures. They have collaborated with the U.S.
Embassy in Costa Rica and the Costa Rican Ministry of Health to enhance awareness about histoplasmosis risks. Tour operators are now required to include information about these risks in their waiver forms, ensuring that future visitors are informed before embarking on cave tours.
Additionally, a health alert was issued in March 2025, warning the public about the potential dangers of contracting histoplasmosis from the caves.
This incident serves as a crucial reminder for travelers to be aware of the health risks associated with certain tourist activities. As the popularity of adventure tourism grows, so does the need for increased awareness and safety measures to protect individuals from preventable health issues.
