It’s estimated that 230,000 Canadians are currently infected with hepatitis B, although only 58 per cent of them are aware of their infection. [Kwok's note: that means 42% are not aware they are carrier of the Hep B virus. Scary]

Hepatitis A is rare in Canada and Patterson said the majority of cases over the past decade have been the result of people being infected while traveling to the Caribbean, South America or Africa, and then developing symptoms once they've returned home.

It’s estimated that about 79 million Americans have HPV but many don’t even know they’re infected, as most people never develop symptoms.
