Pandemics

The current global health landscape is characterized by a moderate risk level due to several factors: COVID-19 levels are rising slightly in the US, with wastewater surveillance indicating potential increases in cases. Additionally, there are new polio cases in multiple countries, a measles outbreak in Michigan, and ongoing H5N1 avian flu infections, particularly in Cambodia. Despite strong vaccine protection against severe COVID-19 outcomes, uptake remains low among high-risk groups like cancer patients. Furthermore, misinformation and vaccine hesitancy continue to undermine public health efforts, as seen in the legal challenges to vaccine policies and declining vaccination rates for diseases like measles. These factors, combined with the emergence of other infectious diseases like MERS and chikungunya, contribute to the current moderate risk level.
