Influenza (Flu)

Influenza, often referred to as the flu, is a common, contagious respiratory illness. There are four types of influenza viruses: A, B, C and D. While influenza A, B and C viruses can infect humans, influenza D is believed to primarily affect animals such as cattle and pigs. Influenza C is rare in comparison to influenza A and B, which are the main sources of the “seasonal flu,” or the viruses that circulate in Canada and other countries each winter. Influenza A is also the source of flu pandemics. Canada has experienced five influenza pandemics since the late 19th century, in 1890, 1918, 1957, 1968 and 2009. In Canada, influenza causes an estimated 12,200 hospitalizations and 3,500 deaths each year.

Mental Health

In the early years of the mental-health movement, mental health was often defined as the absence of symptoms of mental illness. Since that time, attempts have been made to relate mental health to a concept of psychological well-being and to certain capacities of individuals, eg, the capacity to perceive reality "objectively," to be flexible in meeting new situations and to understand another's point of view. However, no clear line divides the mentally healthy from the mentally unhealthy, and in addition, the definition of mental health is relative and is dependent on cultural context. The characteristics of a mentally healthy person in one milieu may seem very different from those of a mentally healthy person in another.
