What is double pneumonia and is it contagious my grandma had it and now i'm having the symptoms chills fever chest pain sore throat also have allergie?

Dbl pneumonia: Double pneumonia means that there is infection in both lungs. It is not per se contagious - acquiring pneumonia of any type is more about the health of the host than the virulence of the infecting organism (with a few exceptions). Your symptoms could be consistent with pneumonia or pleurisy and could follow a viral infection. You should be evaluated in person - you may need blood work and a cxr.
