Reading through the report on the 1978 smallpox cases, I was surprised by the detailed tracking of the 1966 outbreak of the less-fatal version, variola minor, spread by another photographer working in the same area above the virus lab. In general, he spread it to nonvaccinated people, and not to his vaccinated fiancee, but to her co-workers. Shaving spreads infections! Folk dancer gets it sitting across the table, but vaccinated wife dances multiple times safely! Uncooperative old guy claims to be vaccinated, but spreads infection to his family and a much larger outbreak, including a teenage bus outing! Thank goodness we learned our lesson then about vaccines and the protective value of beards ...
(And it was a utility duct, for steam pipes, etc., with poorly sealed access panels, not a ventilation duct as I had recalled.)
