Final answer:
The disease not associated with coronavirus infections is German measles, caused by the Rubella virus and not a coronavirus.
Step-by-step explanation:
The disease not associated with coronavirus infections is German measles (Rubella). The diseases caused by coronaviruses include COVID-19, which is caused by SARS-CoV-2, Severe Acute Respiratory Syndrome (SARS), and Middle East Respiratory Syndrome (MERS). These viruses cause respiratory symptoms that can range from mild, like those associated with the common cold, to severe, as seen in SARS and MERS cases. German measles, however, is caused by the Rubella virus, which is not a coronavirus. Vaccines have been developed for German measles while COVID-19 vaccines are also now available, but there are currently no specific vaccines for SARS or MERS.
