Lucknow witnessed 13 fresh cases of dengue, taking the toll to 125 patients testing positive in two months.

The patients who have tested positive on Thursday include six females, one of them an 82-year-old woman.

Of the seven male patients, two are minor boys – aged 11 and 15 years.

The cases have been reported from different localities including Gomti Nagar, Ruchi Khand, Hazratganj, Tikrohi, Bazarkhala, Salehnagar, Neelmatha, Indira Nagar, Sharda Nagar and Rajajipuram.

According to health officials, dengue fever has affected 173 persons in the state capital alone, with the maximum number of cases being reported in August and September.

The health department served notices to 14 houses where conditions were found suitable for mosquito breeding.

The Lucknow Municipal Corporation (LMC) is also planning to carry out extensive fogging in the city in view of the increased dengue threat.

The officials said that desert coolers are the main breeding grounds of mosquitoes, 70 per cent cases were found in water accumulated in desert coolers. People need to clean coolers on a weekly basis or pour kerosene oil in the water tank to kill larvae, the officials said.

A senior doctor of the Balrampur hospital said, “A number of cases go unreported because people mistake the symptoms for viral fever which is also very common in this season.”
