Biggest fungus outbreak in US history sees nearly 100 staff at paper mill in Michigan struck down by rare mold strain that kills one in 100 victims

Nearly 100 people have been infected and a dozen hospitalized by a rare fungus linked to a paper factory in Michigan.

The fungus Blastomyces is feared to have arrived on moist and rotten wood at the Billerud paper mill in Escanaba, in the north of the state.

Experts told DailyMail.com that the scale of the outbreak was ‘extraordinary’ — and, if confirmed, would be the largest recorded in the US ever.
