Researchers studied fungi living in beach sand and seawater along Iran’s Persian Gulf and Sea of Oman coastlines to understand potential health risks. They found that dangerous fungi, particularly Aspergillus species, were present at levels exceeding safe thresholds for swimmers and beach visitors. Many of these fungi showed resistance to common antifungal medications, which is concerning for people with weakened immune systems. The study suggests that beaches need better monitoring and sanitation programs to protect public health.
