Recently, Argentina has reported 3 death due to Mystery pneumonia.
Mystery pneumonia could not be explained yet but it is affecting people in a certain way.
Three people have died and nine people have been sick overall due to this mysterious disease.
Researchers haven't detected Covid or other flu viruses, but officials are still looking into what's going on.
The third infected person was a 70-year-old woman who had been taken to the hospital for surgery.
The other individuals who got infected are the people who work under the medical staff.
The unknown sickness killed two clinic workers in two days.
The people who didn't survive showed the same health issues as the 70-year-old woman had.
The health minister of Tucumán said that the people who died had "a severe respiratory disease with bilateral pneumonia, similar to Covid."
The University of Oxford's Professor Sir Peter Horby said, "No one needs to freak out too much. The cause for this would be discovered.Not too worried right now, but I'll be keeping a close eye on it."
