A cleanup is still underway at a Brooklyn storage facility where a man contracted anthrax. The district manager of Pinacle Storage says the site where anthrax was discovered is open to customers. However, the warehouse still has two floors closed for cleaning, which are expected to reopen in about four days. The company is still waiting for tests results to see if there are any traces of anthrax in the air duct system. City health officials believe Vado Diomande, 44, became infected while making drums at the warehouse from animal hides he purchased on the Ivory Coast in December. Over the weekend Diomande's condition improved from serious to fair. He is being treated at a hospital in Pennsylvania.
