The second measles case reported in Ottawa, ON affects a 36-year old women with a rare form of cancer called peritoneal mesothelioma, which affects the abdomen.
The woman contracted measles while on vacation, despite having up-to-date vaccinations for the disease. Her cancer made her immuno-compromised which raised her risk.
The importance of having up-to-date vaccinations cannot be over-stated. Even those who are vaccinated may be immuno-compromised if they have an existing illness such as cancer, and measles is a particularly dangerous disease for those with weakened immune systems.
