Maharashtra Food and Civil Supplies Minister Chhagan Bhujbal on Monday said he has tested positive for coronavirus.
Mr Bhujbal is the seventh minister to be infected by the novel coronavirus this month.
In a post on Twitter, Mr Bhujbal said his health is fine.
"I have tested positive for COVID-19. All those who came in my contact over the past two-three days should get themselves tested," he tweeted.
"My health is fine and there is no reason to worry. All citizens should take proper care in the backdrop of COVID-19. Should wear masks and use sanitisers regularly," the NCP leader added.
