Final answer:
German measles (Rubella) is not caused by a coronavirus but by a togavirus, making it the correct answer to the disease not associated with coronavirus infections.
Step-by-step explanation:

They can cause illnesses ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). However, German measles, also known as Rubella, is not caused by a coronavirus but rather by a togavirus, and therefore is the correct answer to which disease is not associated with coronavirus infections.
