An Upper Respiratory Infection (“URI”) occurs when a virus or bacteria enter your nose, mouth, or throat. That invasion causes inflammation, which leads to the runny nose, congestion, sneezing, and sore throats we have all experienced.
The vast majority of URIs are caused by viruses, such as rhinovirus, influenza, and coronavirus, (not exactly that coronavirus). COVID-19 is a specific type of coronavirus: while it enters your body the same way other URIs do, COVID-19 causes inflammation in areas of your body far beyond the upper respiratory tract. Inflammation in blood vessels causes clots, while inflammation in lungs results in breathing problems. That loss of taste and smell COVID-19 is known for is a result of nerve inflammation.
In many cases, a loss of taste and smell reported by the patient has been a marker of the COVID-19 virus, but that isn’t always true. The most accurate way to find out if you have COVID-19 is to get a test (find testing centers near you). If you’re experiencing symptoms of loss of taste and smell, limit engagement with friends and family until you receive your test results.
