What is the importance of the Chorus is the novel, Monstro?

The "eerie siren-like" shriek emitted in unison by the infected in the hospital zone symbolizes the indomitability of the human community of the world's most vulnerable to disaster and diseased. Even as the black, fungus like growth covers their bodies, the metamorphosing victims never lose their voices, and in fact become joined as one "beacon" to draw the still-healthy to its source. The Chorus, and the "ingathering compulsion" (108) it stimulates in others, is Diaz's political statement abut the dignity and self-determination of the Haitian people, and to African descendants and poor or disposed people everywhere. That the eventual monsters seek "fusion" with each other, and the uninfected seek to join together with them, asserts the noble human virtue of standing tall, together, yet isolated and doomed.
