- In the early months of the COVID-19 pandemic, doctors noted that a loss of smell was a noticeable symptom. Dr. Carl Philpott of the University of East Anglia (UEA) in the UK has studied this effect for months and learned that while the loss of smell during a cold or allergies is caused by congestion, people with COVID-19 can usually breathe freely. The virus instead affects their central nervous system. The effect is usually temporary, but in some patients, long-term.
