On the micro-blogging site Twitter, Kejriwal said, "If you vote for BJP, then next five years will be full of garbage and mosquitoes."
"If you vote for the BJP and if your child falls prey to chikunngya or dengue, you are responsible for it. I can offer free treatment to your child in (the Delhi government) hospitals, but what led to him contracting dengue", he said.
"If someone in your home falls ill then you are responsible because you voted for the party which is synonymous to chikhungunya, malaria, dengue and garbage," he said in a stinging attack on the BJP.
Making a fervent appeal to vote for an "honest Aam Aadmi Party", the Chief Minister said his party will clean Delhi in a year and eradicate vector-borne diseases in the next three years.
He said that the Congress is "dead" in Delhi and at the national level, and voting for them would mean "wasting your vote."
Kejriwal also alleged that with just two days left for the MCD polls, the BJP and the Congress are resorting to the "cheap politics" by engineering the water and power shortages.
BJP को वोट दिया तो अगले 5साल कूडा,मछर ऐसे ही रहेंगे।कल अगर आपके घर डेंगू हो जाए तो आप ख़ुद उसके ज़िम्मेदार होगे क्योंकि आपने BJP को वोट दिया— Arvind Kejriwal (@ArvindKejriwal) 21 April 2017
दिल्ली वालों के लिए भाजपा "डेंगू और चिकनगुनीया वाली पार्टी" है।— Arvind Kejriwal (@ArvindKejriwal) 21 April 2017
In an another tweet, Kejriwal said, "The BJP and the Congress are disconnecting water and electricity connections at various places. With folded hands, I appeal, "Please disconnect my water and power supply, but please do not bother my Delhi people."
"The BJP and the Congress are stealing oil from the power transformers and ensuring that there is power shortage. They are doing it deliberately and resorting to cheap politics by disrupting water and power supply," he alleged.
"Your fight is with me, so do not harm the people of Delhi," he said, adding that such acts will continue till Sunday, the polling day.
Kejriwal also accused the BJP of trying to mask its "misdeeds" by asking people to vote for the party in the name of Prime Minister Narendra Modi.
Kejriwal's tweet on dengue led to a controversy in the social media, where people labelled his remark as a threat and a tool to blackmail Delhi voters.
Shortly after Kejriwal's insensitive statement, #DengueForVotes was trending on Twitter. Here are some reactions:
