The health crisis in the Pakistani city started on Sunday night as people living near the port of Karachi complained about breathing problems, tightness in the chest, and a burning sensation in the eyes. Other symptoms include dizziness and nausea. Some reported smelling an unfamiliar odor before feeling sick.
The mysterious illness, which was initially blamed on a gas leak, soon proved to be fatal. On Monday eight people were reported dead, while on Tuesday the death toll rose to 14. More than 250 people were treated for lung problems before being discharged, local hospitals said, while a handful remained in intensive care.
Karachi Commissioner Iftikhar Shallwani said the outbreak was a localized event affecting an area near the port. While no cause was immediately identified, city health officials said hydrogen sulfide could have been responsible. The colorless gas notorious for smelling like rotten eggs is toxic - it was even used as a chemical weapon during WWI - and may be released during improper handling of oil products.
