Which illness presents with abrupt onset of fever, chills, headache, myalgia, malaise, sore throat, and bilateral tender cervical lymph nodes?

• A. Allergic rhinitis
• B. Common cold
• C. Pneumonia
• D. Influenza

Answer: (D)

The key idea is a sudden, febrile viral illness with prominent systemic symptoms. Influenza tends to come on abruptly with high fever and chills, along with severe headache, generalized muscle aches (myalgia), malaise, and sore throat. Lymph node tenderness can occur as part of the body’s response to infection, including bilateral cervical nodes. In contrast, a common cold usually starts more gradually and features milder fever or none at all, with nasal symptoms predominating. Allergic rhinitis lacks fever and systemic symptoms, presenting with sneezing, itching, and nasal congestion. Pneumonia, while it can involve fever, typically presents with more focal respiratory findings such as a productive cough, dyspnea, chest pain, and abnormal lung exam, rather than the diffuse systemic symptoms and cervical lymphadenopathy seen here.
