MERS, an interferon/innate immune deficiency state, continues to surge
June 2, 2014
The Middle East respiratory syndrome (MERS) is an infectious viral disease with about 30% mortality caused by viral pneumonia and associated lung damage. The etiologic agent of MERS, MERS-CoV, is a member of the coronavirus family. Coronaviruses are responsible for a variety of pathologic effects in a broad spectrum of vertebrates including the virus currently responsible for epidemic piglet deaths in hog farms in the United States. The pathogenicity of MERS is due, in part, to the innate immune deficiency state that results from inhibition of a first responder to viral infection, interferon (IFN).
