The answer is C. Hysteria.
Typhoid, measles, and influenza are all infectious diseases caused by viruses. Hysteria, on the other hand, is a psychological condition that is not caused by a virus.

Measles is a viral infection that is spread through the air. Symptoms of measles include fever, cough, runny nose, red eyes, and a rash. Measles can be prevented with a vaccine.
Influenza is a viral infection that is spread through the air. Symptoms of influenza include fever, cough, sore throat, runny or stuffy nose, muscle or body aches, headache, and fatigue. Influenza can be prevented with a vaccine.
Hysteria is a psychological condition that is characterized by uncontrolled emotional outbursts. Symptoms of hysteria include crying, laughing, screaming, and fainting. Hysteria can be treated with therapy and medication.
