The alleged mishandling of COVID-19 cases by the Vasai Virar City Municipal Corporation has led to the spread of the virus in the Vasai-Nalasopara-Virar stretch. The virus has reportedly reached the Santosh Bhavan slum and its adjacent chawls, Shriram Nagar and Dhaniv in Nalasopara East, where the lanes are narrower than Mumbai's Dharavi, and which have a population of nearly 8 lakhs.
