Thanawat Tiensin, etc.,al. Transmission of the highly pathogenic avian influenza virus H5N1 within flocks during the 2004 epidemic in Thailand. J Infect Dis
This present study is the first to quantify the transmission of avian influenza virus H5N1 within flocks during the 2004 epidemic in Thailand. It uses the flock-level mortality data to estimate the transmission-rate parameter () and the basic reproduction number (R0). The point estimates of varied from 2.26/day (95% confidence interval [CI], 2.01–2.55) for a 1-day infectious period to 0.66/day (95% CI, 0.50–0.87) for a 4-day infectious period, whereas the accompanyingR0 varied from 2.26(95%CI, 2.01–2.55) to 2.64(95%CI, 2.02–3.47). Although the point estimates of of backyard chickens and fighting cocks raised together were lower than those of laying hens and broiler chickens, this difference was not statistically significant. These results will enable us to assess the control measures in simulation studies. They also indicate that, for the elimination of the virus, a critical proportion of the susceptible poultry population in a flock (i.e., 80% of the population) needs to be vaccinated.
