This is a list of errors and typo within the book. Hopefully many of
these errors will be corrected in subsequent re-prints.
Chapter 1, Chapter 2, Chapter 3, Chapter 4, Chapter 5, Chapter 6,
Chapter 7, Chapter 8.
Page 46, Equation (2.60) The two terms on the right hand side should be
added together; the minus sign should be a plus sign:
St+1 = µ + St e-βIt
Page 123, Equation (4.10) The last equation should either be the
rate of change of the infectious population dIi /dt, or the equation for the force
of infection associated with strain i
can be written as seen in Program 4.2. The model
assumes that λi
= β Ii, and that the
parameter Ωijk in
Gupta's 1998 paper is zero.
Page 238 (Section 7.2) the expression for the force of infection in a
metapopulation is incorrect -- we should be finding the weighted sum of
the infection (Yj)
not the susceptibles (Xj).
In addition, the demoninator should be Nj
and not Ni . The full expression
= βi Σj ρij
Yj / Nj
