Nationwide debate erupts as communities reassess water fluoridation practices

In Yorktown, NY, the long-standing practice of adding fluoride to drinking water was halted by the town supervisor due to a federal judge's ruling. This decision stemmed from concerns about fluoride's potential link to lower IQ in children. Similar debates are occurring nationwide, with communities in states like Florida and Texas reconsidering fluoridation. Recent studies suggest that high fluoride levels may negatively impact brain development, prompting calls for regulatory review. While fluoride is recognized for its dental benefits, opposition has grown, fueled by emerging research and public sentiment. Health organizations continue to support fluoridation, emphasizing the need for careful evaluation of new findings.1

New evidence suggests potential sexual transmission of Oropouche virus

Oropouche virus is gaining attention due to a significant rise in cases, with over 10,000 reported in 2024, primarily in Brazil. This arbovirus, transmitted by mosquitoes and biting midges, can cause symptoms like fever and rash, but severe cases may lead to encephalitis or meningitis. Recent studies suggest potential sexual transmission, raising new public health concerns. CDC issued guidance recommending that male travelers with symptoms consider using condoms for at least six weeks post-symptom onset. Factors such as deforestation and viral reassortment may contribute to the surge in cases, indicating a need for enhanced surveillance and preventive measures.2

Are continuous glucose monitors the next health craze for non-diabetics?

Following FDA clearance in March, continuous glucose monitors (CGMs) are now available over the counter for people without diabetes, but their benefits for this population remain uncertain. Some experts believe these devices can help individuals make healthier lifestyle choices by providing real-time glucose data. However, there is limited evidence supporting the health benefits of CGMs for people without diabetes, and some in the diabetes community feel this trend trivializes their condition. Additionally, the cost and accessibility of CGMs remain significant barriers for many patients with diabetes.3
