Around 300 fatalities and over 18,000 pneumonia cases were registered in eastern Punjab for January.
Around half of childhood pneumonia deaths are associated with air pollution, according to Unicef.
The provincial government extended school holidays, clipped classroom hours and mandated face masks in a bid to shield children.
