Pandemics

The current landscape of infectious diseases presents a moderate risk, largely driven by an uptick in COVID-19 cases in certain regions, as well as the emergence of other infectious threats like H5N1 avian flu and MERS, which have shown potential for cross-species transmission and human infection. Vaccine hesitancy remains a significant barrier to achieving higher vaccination rates, particularly in high-risk populations such as cancer patients and children. Surveillance tools are improving, such as wastewater monitoring for COVID-19, but misinformation and public distrust in health agencies continue to undermine public health efforts. Additionally, the persistence of long-term health effects from COVID-19 and the potential for new variants pose ongoing challenges to global health security.
