From Wikipedia :

Although Camus’s approach in the novel is severe, his narrator marks the ideas that , in the end, we have no control, (i)rrationality of life is inevitable, and he further shows the human reaction towards the ‘absurd’. The Plague represents how the world deals with the philosophical concept of the Absurd, a theory which Camus himself helped to define.
