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.

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.

Mosquito-breeding has been reported from at least 8,546 households and 10,280 legal notices have been issued this year.
