Airport Screening Unlikely To Prevent Spread Of SARS Or Influenza

I guess more than electronic sniffers would be needed to prevent the spread of infectious diseases worldwide.
In a recent study published in British Medical Journal the investigators found that the incubation period for diseases would allow infected people through airport screening system anyway.

Airport Screening Unlikely To Prevent Spread Of SARS Or Influenza

Screening passengers as they arrive at UK airports is unlikely to prevent the importation of either SARS or influenza, finds a study published online by the British Medical Journal.

In the event of a new SARS or influenza epidemic, air travel would represent the principal route of international spread. Although airport entry screening has been advocated, its benefit is currently unknown.

Using the incubation periods for influenza and SARS, researchers at the Health Protection Agency estimated the proportion of passengers with latent infection who would develop symptoms during any flight to the UK.

For SARS, they found that the incubation period was too long to allow more than a small proportion of infected individuals to develop symptoms during a flight to the UK (0-3% for European flights and a maximum of 21% for the longest flights from East Asia).

Although influenza has a much shorter incubation period than SARS, the average predicted proportion of people infected with influenza and progressing during any flight was still less than 10%.

Early screening is unlikely to be effective in preventing the importation of either SARS or influenza, they conclude.
