*Influenza virus	High fever + myalgia
(Salmonella Shigella	Protracted diarrhoea
*Eosinophilia-Myalgia Syndromes: Toxic Oil Syndrome Tryptophan Intake Eosinophilic Fasciitis	Eosinophilia + myalgia + inflammatory response
*Fascioliasis Toxocariasis Invasive Schistosomiasis	Eosinophilia + fever
*Glomerulonephritis Serum Sickness Allergic reactions to drugs or allergens Polymyositis Dermatomyositis Periarteritis Nodosa	Periorbital or facial edema + fever
*Infectious Meningitis Encephalitis	Intense headaches + stiff neck + confusion + drowsiness + irritability + neurological symptoms
