Interesting because the Daily Times of London attributes this picture to UNICEF (and the watermark in their picture does as well). You cite a Boston paper with a nice little foot note that doesn’t match any other usage of this picture.
This is why I want to know sources of pictures. It is like trying to figure out if the aspirin factory had a bomb making section in the basement. The truth is there exist lots of pictures out there. Some show folks in some form of protective gear and this picture is definitely not in a hospital...maybe in a triage center away from the city) and other pictures show medical personnel treating people with no protective gear.
What does UNICEF say it is?
