Bird Flu is spreading in West Bengal and Kolkata may be next. The deadly virus has been identified in seven districts; Bankura and Malda are the latest. Chickens have also died in two other districts, South 24 Parganas and North 24 Paragnas, which are close to the state capital but authorities there have not yet confirmed the virus yet. Many are alarmed at the spread because it's happened so quickly.
