Is Respiratory Syncytial Virus (RSV) Contagious?

Updated August 11, 2023


Respiratory Syncytial Virus (RSV) is contagious and is transmitted from person to person. It is spread by coughing, sneezing, or by direct contact with the virus. A person can become infected by coming into contact with the respiratory secretions of an infected individual, usually through coughing or sneezing, or by touching the virus directly (ie kissing). It is also possible to become infected by the virus by touching contaminated surfaces and then touching the face. 

Most infected individuals are usually contagious for between three to eight days, although some people can transmit the virus to others for up to two days before symptoms begin. Immunocompromised individuals may be contagious for up to one month.
