Foreword: Improving the Hospital’s Indoor Air Quality

Among hospitals-related health risks, environmental factors play a key-role; this accounting for different rooms’ specific use, patients’ vulnerability and risk of overcrowding. For these reasons, air quality control in hospitals—and in healthcare facilities—in general—deserves scientific attention. This collection of papers offers a multidisciplinary perspective on the topic, starting from presenting the general concepts of indoor air quality, chemical, biological and physical risk factors in living and working places, then describing the most effective preventive measures that can (and must!) be implemented in order to ensure users’ safety and adverse events’ reduction and including healthcare-associated infections (HAIs).
