A study has revealed that as many as 85 per cent of COVID-19 positive cases in Mizoram’s capital Aizawl transmitted through close contact with friends and neighbours, a health department official said Wednesday. 

The study conducted by medical operational team on Covid-19, headed by ruling Mizo National Front (MNF) MLA Dr ZR Thiamsanga during lockdown, has revealed that 85 per cent of Covid-19 positive cases in Aizawl, resulted from neighbours visiting each other and meeting friends in the same neighbourhood, despite restrictions imposed during lockdown, the official said. 

He said that the nature of Covid-19 transmission from least 14 localities of Aizawl was studied during the exercise. 

According to the officials, people in the same neighbourhood often visit each other, meet and interact with each other during lockdown, which was one of the main reasons behind rising Covid-19 cases in the state, despite lockdown being imposed for nearly 2 months to break the chain of transmission. 

The study also found that Covid-19 positive case was nil among people, who regularly and appropriately wears masks.
