If you suddenly lose your sense of smell, it is recommended to contact a healthcare provider to discuss the possibility of COVID-19 testing, especially if you have a fever or have been in close contact with someone who has been infected. It is important to stay in voluntary isolation at home until you receive the test results. Avoid using nasal sprays until more information is available about the risk of infection when experiencing sudden loss of smell. Stay informed and take precautions to protect yourself and others.
