It’s more like September than November today. There is no thick morning mist across the flat Fenland landscape, and no need to wrap up in scarves and gloves. People are still going out in tee-shirts, and even shorts. imageNormally around Bonfire Night, you can see your breath in the cold, damp air when you blow out, but it’s still too warm for that.

Yet many people I know have had colds, sore throats and been ill. My son’s  football match was cancelled this week because some of the players were struck with swine flu, and staff have been signed off sick with this illness where my husband works, staff he works closely with.

I am hoping that swine flu will not come to the Seymour house, particularly as I am attending the prestigious Infection 2009 conference next week which will focus on superbugs, pandemics and epidemics, bugs of all kinds – MRSA, bluetongue, C difficile, HIV and TB, as well as swine flu.

One of the papers I read in the conference handbook was about the effect of global warming on increased frequency of pandemic flu in winter, by Mahmood Hachin, from the United Arab Emirates.

His study compared the annual temperature records in winter to find out the pattern of change in climate that predispose a pandemic flu and correlate those changes with the three most known flu pandemics in 1918, 1957 and 1968.

His results showed that the three major pandemics were associated with increased image temperature in winter season compared to the year before the pandemic.

This led to him concluding that global warming is a major factor for pandemic flu when the winter season temperature is higher than that of a previous year, and the atmosphere becomes more favourable for pandemic. This is in contrast to the popular belief that colder winters lead to more cases of flu.

The writing is clearly on the wall. What we don’t know is the extent this pandemic will reach, and I expect that hospitals are preparing themselves for the worst, with most pandemics starting in December, January and February. But whenever it happens, the chances are it will still cause chaos.

*I am delighted that BBC Newsround is coming to film a programme about young people and infections.  I was given their contact details via Twitter by a BBC journalist after a request I made, so it really works. Our conference hashtag is #infection2009.
