Early in the pandemic, when people with COVID-19 began reporting that they lost their sense of smell, Zara Patel, MD, figured as much. A professor of otolaryngology at Stanford Medicine, Patel has, for years, studied loss of smell as a symptom of viral infections.
Many viruses can cause smell loss, so it wasn't surprising to us as rhinologists when we found out that COVID-19 causes loss of smell and taste. It was almost expected.". Zara Patel, MD, Professor of Otolaryngology, Stanford Medicine

Now Patel's team has tested a new treatment for long-term, COVID-19-related smell loss using injections of platelet-rich plasma derived from a patient's own blood. In a trial of 26 participants, those who received the treatment were 12.5 times more likely to improve than patients who received placebo injections.
