"Are sinus infections contagious?" Sinus infections, also known as sinusitis, can sometimes be contagious, particularly if they are caused by a viral or bacterial infection. These infections primarily spread through the release of infected respiratory droplets from coughing, sneezing, or close contact with an infected person. While viral sinus infections are more commonly contagious and can be transmitted easily, bacterial sinus infections are less likely to spread from person to person. To prevent the spread of contagious sinus infections, practicing good hygiene, such as covering your mouth when sneezing and washing hands frequently, is crucial. If you suspect a sinus infection, it's advisable to consult a healthcare professional for accurate diagnosis and appropriate treatment.
