History and respiratory swab testing
Assessment begins with history and symptoms. Tests use a swab from the nose or back of the throat to look for the virus. Some rapid tests provide results in roughly fifteen to twenty minutes but are less accurate than other methods. More accurate tests may take longer. Turnaround time and accuracy are different properties; a fast result should not be assumed to answer every diagnostic question.
Annual vaccination and early care
Most people recover without medical attention and should stay home with mild illness except to obtain care. Very ill, concerned, or high-risk people should contact a professional. Antivirals can reduce severity, duration, and complications and generally work best when started early. Annual influenza vaccination is the best preventive measure described. Handwashing and covering coughs provide additional protection but do not replace vaccination or assessment when needed.
