I was wondering if anyone remembers the name of a film on the bbc back in the 80's which was similar to the film Threads (in relation to nuclear war) but was to do with rabies coming into the U.K. I've been trying to remember the name of it but just cant.

Any help would be appreciated

"The Mad Death" 1981?
