"A total of 19 swine flu patients were detected in Lucknow of whom only two have been admitted in Sanjay Gandhi Post Graduate Institute. The remaining 17 have recovered," Chief Medical Officer S N S Yadav said.
The duo was admitted on Saturday for treatment, he said.
They were earlier undergoing treatment in a private hospital here but their recovery was not up to the mark.
The CMO said he had issued a notice to the private hospital for not informing the health department about the two patients being treated there.
