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,” she said. Patel also knew that the condition could last a while and that few effective treatments were available.

According to a 2022 survey by Patel and colleagues, about 15% of people who experienced smell loss from COVID-19 continued to have problems six months later. That’s roughly 9 million people in the U.S., and the number is growing. Many who report loss of smell also report loss of taste because smell is such a major component of how we experience food.

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.
