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.

Description

After initial introduction and spread in 2002 and 2003, West Nile virus (WNv) is now endemic in parts of the province, especially in south eastern Alberta. Clinicians will need to consider the possibility of WNv infection in their symptomatic patients each summer and fall. This information sheet describes the clinical features of WNv infection and is intended to assist clinicians in determining when WNv infection should be considered in a differential diagnosis and when testing for WNv infection should be considered.
