At least nine dengue cases have been reported in Delhi this year, even though the vector-borne disease is usually reported between July and November, according to a municipal report released Monday.
Last year, 2,798 dengue cases and four deaths were recorded by the South Delhi Municipal Corporation (SDMC), which tabulates data on vector-borne diseases in the city.
According to the report, a case was reported in May, two in April, four in March and one each in February and January this year.
Cases of vector-borne diseases are usually reported between July and November, but the period may stretch to mid-December.

The dengue victims last year included a minor boy. Three of the victims were identified as Aman Tiwari (13), Sanskriti (21) and Gagan (23).
Doctors have advised people to take precautions to ensure that there was no breeding of mosquito larvae around them and urged them to wear full-sleeves and use mosquito nets.
Water coolers should be dried up when not in use as dengue infection-carrying mosquitoes breed there a lot, a doctor said.
Civic bodies had also recently organised a workshop on the prevention of vector-borne diseases.
Mosquito-breeding has been reported from at least 8,546 households and 10,280 legal notices have been issued this year.
