This was based on 10 years of data gathered from influenza-like illness sentinel physician and laboratory surveillance, and experimental viral shedding data in Taiwan. Methods: We integrated sentinel physician-reported cases and positive rates of influenza A (H1N1), A (H3N2), influenza B, and respiratory syncytial virus in Taiwan using the Wells-Riley mathematical model. This model incorporates environmental factors such as room ventilation and breathing rates. We also linked vaccine match rate with related transmission estimations to predict the controllable potential using a control model characterized by basic reproduction number (R0) and proportion of asymptomatic infections (θ). Results: A quantitative framework was developed to better understand the infection risk and R0 estimates of A (H1N1), A (H3N2), and B viruses. The viral concentration in human fluid was linked successfully with quantum generation rates to estimate virus-specific infection risks. Our results revealed that A (H3N2) virus had a higher transmissibility and uncontrollable potential than the A (H1N1) and B viruses. Conclusions: Probabilistic transmission model can incorporate virus-specific data on experimental viral shedding, long-term sentinel physician and laboratory surveillance to predict virus-specific infection risks in Taiwan. ? 2009 The British Infection Society.application/pdf1136120 bytesapplication/pdfen-USIndoor transmission; Infection; Influenza; Modeling; Vaccine[SDGs]SDG3influenza vaccine; ambient air; article; basic reproduction number; breathing rate; disease surveillance; environmental factor; human; infection control; infection risk; influenza; influenza vaccination; Influenza virus A H1N1; Influenza virus A H3N2; Influenza virus B; mathematical model; prediction; probability; quantitative analysis; Respiratory syncytial pneumovirus; risk assessment; room ventilation; Taiwan; virus concentration; virus load; virus shedding; virus transmission; Air Microbiology; Air Pollution, Indoor; Humans; Influenza A Virus, H1N1 Subtype; Influenza A Virus, H3N2 Subtype; Influenza B virus; Influenza, Human; Kinetics; Models, Statistical; Risk Assessment; Sentinel Surveillancejournal article10.1016/j.jinf.2009.09.015http://ntur.lib.ntu.edu.tw/bitstream/246246/176047/1/97.pdf
