There are two types, A and B. Classification is based on their pathogenicity in mice. Type A causes paralysis and death in mice while type B causes more mild symptoms.
What are the three top viral causes of aseptic meningitis?
Coxsackie, echo and mumps virus.
What asymptoms are common to both types A and B?
Both types can cause aseptic meningitis and paralysis through involvement of the meninges and anterior horn motor neurons. They can also cause upper respiratory tract infection by dissemination through the bloodstream.
What are the pathogenesis and clinical symptoms specific to Coxsackievirus A?
Type A has a predilection for skin and mucosal membranes and causes herpangina(fever,sore throat and tender red vesicles on the back of the throat) and hand foot and mouth disease(vesicular rash on the hands and feet and ulcerations in the mouth).
What are the pathogenesis and clinical symptoms specific to Coxsackievirus B?
Type B has a predilection for the heart and pleural surfaces and causes pleurodynia(fever, headache, and severe chest pain on breathing due to pleural infection), myocarditis(50% of all viral cases), and pericarditis(chest pain, arrhythmias, cardiomyopathy, or heart failure). Pancreatic damage possibly leading to juvenile diabetes may also occur.
