A Matter of WHO is a 1961 British comedy thriller film directed by Don Chaffey and starring Terry-Thomas as a World Health Organization employee trying to trail the source of a deadly virus.[1] It also featured Julie Alexander, Sonja Ziemann, Alex Nicol, Richard Briers, Honor Blackman and Carol White.

It was made at MGM-British Elstree Studios with sets designed by Elliot Scott. MGM records say it lost $142,000.[2]


Aboard an airliner flying from Nice to London, an oil driller returning from the Middle East named Cooper becomes very ill. This attracts the notice of World Health Organization self-styled "germ detective" Archibald Bannister. It turns out that Cooper's new wife, Michèle, and his business associate, Kennedy, know each other.

Bannister is reprimanded by his boss, Hatfield, for previously shutting down London Airport because of what turns out to be an ordinary rat. This time, however, Cooper is diagnosed with highly infectious smallpox. There are also outbreaks in Brussels and Zurich. Bannister suspects that all three cases were contracted from a fourth person, a carrier.
