In 2000, 3,399 babies died before their first birthday, a rate of 5.6 deaths per 1,000 live births.
The rate was 5.8 per 1,000 in 1999.
In 2000, there were 243 `sudden infant deaths',
a rate of 0.40 per 1,000 live births.
The rate was 0.45 per 1,000 live births in 1999.
CESDI carried out the largest single study of cot deaths ever undertaken
worldwide (published Feb 2000); studied 460,000 births over 3 years in 3
different areas of UK. This government-sponsored study recorded 323 cot
deaths of which 5 were second cot deaths in the same family, a ratio of
The possible causes of cot death include
genetic and environmental influences.
In the case of Sally Clark's children Christopher and Harry,
vaccination seems to be
suspiciously associated with their deaths.

law suits in the USA, see this article.
This page notes other
variables known to be correlated with cot death.
Genetically inherited conditions
It is highly likely that there are genetically inherited
conditions that make children more likely to die young.
One example is a mitochondrial mutation, such that, if the mother
has the mutation, there is a roughly one-in-three chance
of the child's dying. [Mitochondrial DNA is inherited from the

Genes affecting the brain
Gene may be key to cot deaths cause
A gene which helps maintain the brain in good working order may hold
the key to understanding the causes of cot death.
Scientists in Edinburgh are investigating the possibility infants
become victims of the condition as their brains are less able to cope with
unexpected environmental changes, such as minor infections or overheating.

- These plots, kindly supplied by
Jenny Mooney (jennym-at-maths.abdn.ac.uk),
show the number of cot deaths per month
in the UK. There are clear seasonal trends,
which changed after 1991, when the government ran a campaign
to reduce cot death incidence. In the abscence of the government
campaign, the cot death frequency in the winter months
was about twice that in the summer. [Both Christopher and Harry
died in the winter.]
Infection by bacterium
from Compuserve news Thu Apr 25 2002
MILAN, Italy (AP) - Sudden Infant Death Syndrome, in which apparently
healthy babies die inexplicably in their cribs, may be linked to infection
with a common bacterium, preliminary research suggests.
Researchers told a conference on infectious diseases Thursday that a
shock-producing byproduct of E. coli was found in the blood of all SIDS
babies tested, but in none of the infants used as a comparison.
Experts not connected with the research said the toxic infection theory is

Journal of the Australasian College of Nutritional & Environmental Medicine Vol 20 No 2 August 2001.
In a nutshell, `Vaccines kill babies'.
Some so called
`shaken baby' deaths are attributed to vaccination.
Blockage of larynx
Elaine Morgan's theory suggests that sudden infant deaths
are due to the blockage of the
larynx by the uvula at that period of life, roughly at 3 to 6 months,
when the larynx is descending. It is a part of the theory that after death, when the dead baby is
moved, that the uvula slips out of the entrance to the larynx and thus no evidence remains to show
