Viral syndrome refers to a suite of symptoms associated with viral illnesses, such as coughing, congestion, a sore throat, gastrointestinal distress and a fever, according to the University of Minnesota. Viruses create a number of different symptoms, which differ in severity and duration depending on the virus causing the infection and the type of illness. Some illnesses, such as the cold and common flu, produce symptoms that typically resolve quickly while others require extensive treatment.
Treatment for viral syndrome varies depending on the age of the person affected and the area within the body of infection. Viruses, also called viral illnesses, can produce a wide range of symptoms. Viruses that congregate in the upper respiratory tract, head, throat or lungs may produce symptoms such as head congestion, nasal congestion, earache and a cough or sore throat. Viruses that attack the gastrointestinal system may produce stomachaches, nausea and diarrhea. Other systemic viruses produce a general feeling of malaise, extreme fatigue or general muscle aches and muscle soreness. Illness from viruses typically last from one to two weeks, although some may linger for a month or longer. Some more serious conditions, such as infections, may present the same symptoms as common viruses. Typically, patients undergo tests to determine whether illnesses are viruses or more serious infections.
