Combating Infectious Disease Challenges: Have We Gone Twenty Steps Forward or Backward?

The 2025 webinar: “Combating Infectious Disease Challenges: Have We Gone Twenty Steps Forward or Backward?” explores the need for a paradigm shift in public health strategies to address airborne pathogens. Despite growing awareness, many health care systems still underestimate the complexity of airborne transmission, relying on surgical masks for protection against airborne pathogens and on outdated assumptions that aerosol-generating procedures are required to spread them. Evidence shows that pathogens can be aerosolized through Aerosol-Generating-Activities (AGA), which are undertaken every day, such as breathing, talking, and singing, necessitating the use of respirators (eg, N95 masks), airborne infection isolation rooms, and improved indoor air quality. Upgrading HVAC systems and maintaining indoor CO 2 levels below 800 ppm are critical steps toward safer environments. The importance of One Health was highlighted by a discussion of H5N1, including its impact on our food supply and its potential to mutate, which could allow sustained human-to-human transmission. Vaccination remains a cornerstone of infectious disease prevention, credited with saving an estimated 154 million lives globally over the past 5 decades. However, misinformation continues to erode public trust, with nearly 25% of Americans believing the MMR vaccine may cause autism—threatening herd immunity for diseases like measles. The webinar also highlights the importance of elimination strategies at the onset of pandemics. While such approaches were effective against MERS and SARS-CoV-1, they failed against SARS-CoV-2. A failure associated with implementation delays and insufficient infrastructure. This webinar underscores the need for evidence-based interventions, public education, and systemic reform to better prepare for future infectious disease threats.
