NEW YORK—Alicia Dubrow, 23, an assistant copy editor at Shape magazine, expressed fear Monday that her recent sore throat is the result of anthrax. "I haven't had a sore throat in, like, two years, and suddenly I get one," said Dubrow, searching WebMD for information on symptoms of the disease. "I've also sort of had a backache lately, which is weird." Dubrow, who made a mental note to watch closely for reddish-brown sores, said she dropped by the Shape mailroom last Friday to grab a box of rubber bands but does not recall handling any packages.
