Case of anthrax may have arisen from cross contaminated envelope

Investigations suggest that the latest case of inhalation anthrax in the United States may have arisen from an envelope that was cross contaminated by contact with other letters containing Bacillus anthracis. This case arose in a 94 year old resident of Oxford, Connecticut. She became unwell on 13 November with fever, cough, weakness, and muscle aches. She was admitted to hospital on 16 November but deteriorated despite treatment and died on 21 November.
