Respiratory Viruses: Influenza (flu), COVID, respiratory syncytial virus (RSV), and many more are spread through the air by coughing and sneezing, or by touching contaminated items and then touching your eyes, nose, or mouth.
The best way to prevent the spread of viruses when you are sick is to:
Stay home and away from others (including people you live with who are not sick) if you have respiratory virus symptoms...
Monitor your symptoms. If you have trouble breathing or chest pain, see emergency medial care immediately.
