New research from the University of Arizona could explain why nearly half of all people who get coronavirus show few or no symptoms.
“This research raises the possibility that pain, as an early symptom of COVID-19, may be reduced by the SARS-CoV-2 spike protein as it silences the body’s pain signaling pathways,” UArizona Health Sciences Senior Vice President Michael Dake said in a press release.

Researchers at UArizona discovered SARS-CoV-2, the virus that causes COVID-19, has the ability to reduce pain by blocking the pain pathway at the cellular level. Viruses infect cells through protein receptors, and coronavirus is no different.
