Figure 9.3.14 Hepatitis A by year
Rate of hepatitis A infections reported per 100,000 population, Middlesex-London and Ontario, 2005 to 2018
From 2005 to 2017, the rates of hepatitis A infections in both Middlesex-London and Ontario were 1.7/100,000 or lower, regardless of the year.
In 2018, the rate of hepatitis A infections among Middlesex-London residents was significantly higher than all other years in the 14-year time period, and was also significantly higher than the provincial rate. Similarly, the rate across Ontario as a whole in 2018 was significantly higher than the previous 11 years. The increase in both the local and provincial rates in 2018 was attributed to an outbreak largely among people who use drugs and those who experience homelessness, and to a lesser extent, men who have sex with men.
