Fig. 1. Comparative PRSV disease progress curves for the Kahuwai PRSV management project area and the remaining areas of Puna from 1999. Superimposed is PRSV incidence data from the original 1992 PRSV outbreak in Puna. For the 1992 and 1999 Puna data, incidence are for approximately 2,200 acres and can be directly compared. The Kahuwai PRSV incidence data are for approximately 1,000 acres. This should be considered in making the relative comparisons.
