Augmenting Surveillance to Minimize the Burden of Norovirus-Like Illness in Ontario: Using TeleHealth Ontario Data to Detect the Onset of Community Activity

Description

Norovirus, commonly referred to as the winter vomiting disease, is the most common cause of gastroenteritis worldwide, with the total number of cases reported per year in Ontario second only to the common cold. The disease is highly infectious, requires a low infectious dose, and is well-known to cause large outbreaks in closely confined populations. While deaths are rare, hospitalization and longterm sequelae are more likely to occur in at-risk populations, such as the elderly or immunocompromised. Action to reduce the number of norovirus infections per year is required due to its health and economic burden. It is estimated that norovirus infections cost the United States 2.5 billion CAD and the United Kingdom close to 200 million CAD per year in health care costs alone. While laboratory surveillance is practiced in Ontario to detect norovirus outbreaks, early detection remains a challenge. This project aims to utilize syndromic surveillance with TeleHealth Ontario data in order to develop an early warning system mitigating the impact of norovirus outbreaks.
