Three fresh cases of dengue were reported on Friday in the capital, which saw the total number of people infected with the disease rise to 70 this season.
"Three new cases of dengue have been reported from the capital," MCD Municipal Health Officer NK Yadav said.
While the civic authorities have already gone on the alarm mode and launched several initiatives to prevent the spread, the disease shows no sign of abating.
The civic officials are also blaming it on the hot and humid weather for the rise in the number of mosquitoes.
"The moisture in the air is creating an atmosphere conducive for breeding of mosquitoes. Moreover, usually we see more dengue cases in the end of August and early September.
"Dengue cases start increasing from August and reach their peak in October before declining. Compared to the same period last year, we have more cases this time," an official said.
Notices have also been issued to offices and premises which were found to be acting as breeding grounds for mosquitoes, while three hundred premises have also been 'challaned', NDMC Municipal health Officer PK Sharma said.
The government buildings which have been issued notices include Nirman Bhawan, Shastri Bhawan, Krishi Bhawan and Sena Bhawan, all housing government ministries' offices, including the CPWD, which is responsible for maintaining government offices.
Besides, the MCD initiated a special sanitation-cum- cleanliness drive in the city early this week to get rid of the mosquitoes. The drive will continue till September 8.
