I recognise the fantastic creativity and hard work of the Blirt team led by Stuart Leo. I dedicate this work to his mother and my sister, Mieke.

I thank my many great teachers that I remember well from primary school: including Miss Pask, Mr Craig, Mr Kenny, and Mr Parmenter,

So very many inspiring secondary school teachers too, though contact was more fleeting

The work in producing Omega: the end of disease, is indebted to teachers, younger and older, including Ms Heidi Hammond and Mr Ken Silburn

I have fond memories of Prof Richard Kemp who taught and ns inspired me to specialise in Infectious Disease prevention, and died himself of a deadly disease.

Many colleagues have helped me greatly in my ID journey including Profs Kroll, Isaacs, Levin, Peckham, Tudor-Williams and Moxon
