Additional candidate "infection" profiles where the contagion activity level I (t) is measured as web hits, downloads etc., and where I (t) ∼ 0 before the initial event, as expected for an outbreaklike contagion phenomenon: (i) swine flu at the level of a county, state, or country, following initial cases-for example, Florida, U.S. at http://www.doh.state.fl.us/Disease- ctrl/epi/swineflu/Reports/reports.htm; (ii) Code-Red outbreak of Internet worm, see D. Moore, C. Shannon, and K. Claffy at http://www.icir.org/vern/imw-2002/; (iii) SARS virus, see p. 18 at http://www.who.int/csr/sars/WHOconsensus.pdf; (iv) website hits for movie Brokeback Mountain following death of actor Heath Ledger. Prior to his death, the web traffic had been essentially zero [i.e., I (t) ∼ 0 as required] for an extended period. See http://www.alexa.com/ for Brokeback Mountain; (v) website hits for a new album by band Radiohead in October 2007. See http://www.alexa.com/ for in rainbows; (vi) outbreak of number of improvised explosive devices (IEDs) in Afghanistan following their first reported use.
