Another child has succumbed to complications due to measles, taking the toll in the ongoing series of outbreaks across the city to 15 in the span of a month. The child, barely five months old, was from Wadala and was the youngest to have died due to measles this year. "The child was born with a congenital heart disease," said BMC executive health officer Dr Mangala Gomare, making him more vulnerable to viral infections.
