Synergistic Effect of Ambient Ozone, Relative Humidity, and Temperature on Epidemic Patterns of Influenza: A Hypothesis and Its Verification

Microbiology and Immunology, EarlyView.
ABSTRACT The mechanisms underlying seasonal patterns in influenza epidemics have long been an enigma. Our laboratory study revealed that ambient ozone significantly inactivates airborne influenza viruses synergistically with higher relative humidity and temperature.
