A constant check of the situation was also launched.
"The sub-divisional medical officer was asked to submit a report immediately about the situation," Darlong told reporters.
Asked, he said the unhygenic lifestyle of the people living in remote and hilly areas coupled with drinking of contaminated water from streams and rivulets without boiling were the main reasons for the spread of the diseases.
