The Biggest Health Stories of 2024

Deep Dive
What are the key health concerns related to drinking water in 2024?
In 2024, drinking water concerns centered on PFAS (per-polyfluoroalkyl substances), lead, and fluoride. PFAS, known as 'forever chemicals,' are linked to liver damage, high cholesterol, cancers, and immune suppression. The EPA introduced regulations to limit PFAS in water systems. Lead, a neurotoxin, remains a threat due to over 9 million lead pipes still in use. Fluoride, added to water to prevent cavities, faces potential removal in some states, driven by political figures like RFK Jr.
Why is bird flu a significant health concern in 2024?
Bird flu reemerged in the U.S. in 2024, with cases in farm workers and dairy cattle. The virus, H5N1, has not yet evolved to efficiently infect humans, but its potential to mutate raises pandemic concerns. A severe case in Canada highlighted the virus's unpredictability. Scientists worry about co-infections with seasonal flu, which could lead to genetic reassortment, a key factor in previous pandemics.
How have obesity drugs like Ozempic impacted health trends in 2024?
Obesity drugs like Ozempic and Wegovy gained immense popularity in 2024, driven by their effectiveness in weight loss. Originally diabetes medications, they mimic hormones that regulate insulin and appetite. High demand led to shortages, prompting pharmacies to produce compounded versions. However, access remains an issue due to high costs and limited insurance coverage. The Biden administration proposed extending Medicare and Medicaid coverage for these drugs, but implementation depends on the Trump administration.
What were the major climate and heat-related health issues in 2024?
2024 was one of the hottest years on record, with global temperatures nearing 1.5°C above pre-industrial levels. Excessive heat was the second most searched term on Google, reflecting widespread awareness. Policy responses included state and city heat rules for worker protection and a proposed national heat standard by the Biden administration. Climate action remains insufficient, with concerns about the U.S. potentially withdrawing from the Paris Agreement under a Trump administration.
What are the potential future developments for bird flu in 2025?
In 2025, scientists will closely monitor bird flu for mutations that could enhance its ability to infect humans. Key concerns include co-infections with seasonal flu, which could lead to genetic reassortment, a process that has driven previous pandemics. The virus's evolution in agricultural workers and wild birds remains a critical area of study, with ongoing efforts to track and mitigate its spread.
