So he's talking about the drug Tamiflu (or oseltamivir to give it it's proper name), and another drug called zanamivir (or Relenza). He quotes data from the Cochrane database and the NICE review from February 2009 and asks
"Do these drugs treat flu? And do they prevent it? ... oseltamivir reduced the average (“median”) time to alleviation of symptoms by 0.68 days. For zanamivir the figure was 0.71 days. So you get better 16 or 17 hours sooner if you take these drugs.
The prevention studies are a bit more exciting. ... oseltamivir 75mg daily was 61% effective compared with placebo, and 73% effective at 150mg daily, while Relenza was 62% effective. In trials looking at preventing influenza in people who were living in households where someone was already infected, the drugs were also pretty good."
To summarise: if you get flu, take it and you'll get better a bit quicker (and probably not feel quite as bad as if you hadn't), and if you have contact with someone who's infectious it's a really good idea to take it as a preventative measure. He argues the drugs aren't that effective, but I disagree. For prevention that's a good figure. I suppose what he's getting at is staying at home, using disposable tissues and catching your sneezes is still the best option to avoid infection. If you're having to use Tamiflu it's a 'last line'.
Now to address the concerns of the panicking amongst you - have a look here. Robert Booy, head of clinical research at the National Centre for Immunisation Research and Surveillance in Sydney says "It's likely this outbreak has been running for ... more than eight weeks [in Mexico]. Influenza tends to, on average, infect two people for every one case. The doubling then occurs every three days, which is the serial interval. This means that from day one to day 30 you go to about 1,000 cases, but in the next month, you go to a million."
So if there have been hundreds of thousands of cases already in Mexico, about 100 deaths gives a mortality rate of 0.1%. Combined with the DoH's worst case figures (30 million infected in the UK) this gives a likelihood of 30 000 deaths IF the infection becomes widespread. So about 3 times as many flu deaths as we get in a normal year. The UK is not going to have a big problem. The developing world will probably not be so lucky.
As I've said before we're not going to end up living in a Mad Max apocalyptic wasteland fighting off hoards of swine flu mutated half pig monsters - pity.
