Sometimes, after a person commits suicide (kills himself), other people will imitate him and kill themselves also. This is called copycat suicide. People may commit copycat suicide after a person they know kills himself, or after hearing about a suicide through television or other media.
After a well-known suicide, there may be a sudden increase in copycat suicides. This is called the Werther effect. Sudden increases in copycat suicides can spread through individual households, school systems, or even across entire countries. These are called cluster suicides.
