A World Bank employee here in Washington has been preliminarily diagnosed with a case of swine flu, Bloomberg is reporting. The employee in question had reportedly traveled on business in Mexico between April 14 and April 18. An email sent to local World Bank offices said that the employee has already recovered from the illness, but colleagues who were in contact with him when he was in the D.C. office on April 20 have been asked to work from home for the time being. A second test to confirm the swine flu diagnosis is reportedly underway. UPDATE: Official statement released by the World Bank is after the jump.
