The new strain of bird flu killed a sixth person in eastern China today, prompting authorities to shut down markets and start culling birds. Nationwide 14 cases of H7N9 have been identified so far. There's no evidence yet that that the flu can spread from person to person—only from bird to person—but Shanghai authorities yesterday said they had quarantined a resident who developed a fever after coming into contact with a patient who had died.
