New Delhi, Oct. 12 -- The decision to open the Delhi Zoo will be taken after October 30, depending on two surveillance results of Avian Influenza (bird flu) at the premises, zoo officials said on Saturday. This comes over a month after the zoo was temporarily closed for visitors on August 30 due to an outbreak of the flu. "The National Zoological Park informs that there is no active presence of the Avian Influenza virus detected at present.
