Description

Degree Days are a measurement of heat accumulation. For the purpose of this report, Degree Days are calculated by subtracting the threshold temperature for West Nile Virus development (14.3 degrees celcius) from the daily mean temperature. Calculating the cumulative Degree Days over a season can be used to estimate the risk of transmission of the West Nile Virus by mosquitoes in Alberta. The risk of transmission increases with increasing Degree Day accumulation. Updated every two weeks during the West Nile Virus season.
