Cot death update 2007

Sudden unexpected death remains the commonest way for post-neonatal infants to die despite a reduction in unexplained deaths of 75% over 20 years. Deaths were frequent in all sections of society but are now concentrated in the more deprived groups where mortality from infection, accident and congenital abnormality has always been greater. The hazards of some forms of infant care are clearer, and clues to the underlying mechanisms are emerging, Although paediatricians are less experienced in sudden deaths, modes of investigation and support are improving.
