Outbreak! public health official: Part 2

Tests come back from the HPA labs, but are still inconclusive.

The infection seems to be something entirely new. Meanwhile, ten new cases are diagnosed in Chortlington; two patients are dangerously ill. Do you:

(a) Request repeat and more extensive testing – they must have missed something first time around.
(b) Contact the Department of Health, passing on all the facts, and organise a local information campaign to calm fears, using press releases and the local radio station, Chortlington FM ('the sunny sound of the seaside').
(c) Ring Downing Street and insist that COBRA is mobilised immediately and Chortlington evacuated.
(d) Seriously consider the offer of early retirement made last year.
