Swine flu has already claimed two lives in Lucknow.
Eighteen more people tested positive for H1N1 virus today, taking the number of cases of swine flu reported in the national capital to 179, including three deaths, so far this season.
"Today, out of 99 samples, 18 have tested positive for swine flu," said RN Das, who is a member of the five-member team constituted by the health department to review the cases.
Mr Das maintained that there was no cause for alarm and the seasonal infection will disappear once the warmer days set in.
Samples are being sent to National Centre for Disease Control (NCDC) to confirm whether they are swine flu cases.
Eleven District Surveillance Officers (DSOs), who have been nominated by the health department to check whether standard operating procedures for treatment of HINI cases are being followed by hospitals, have said there are sufficient amount of medicines available for treatment.
"We have enough medicines in stock. We are again and again instructing the 22 designated hospitals to follow the standard operating procedures for treatment of swine flu," they said.
