How is RSV positively identified?
Respiratory syncytial virus (RSV) can be detected by rapid antigen detection tests (RADTs), direct fluorescent antibody (DFA) and polymerase chain reaction (PCR) testing, and culture. If RSV is the main concern, DFA testing or RADTs may be used, particularly in infants and children.

It is possible for a person to be infected with multiple viruses at the same time.
Should I isolate if I have RSV?
When RSV infections are noted in a facility such as a hospital or nursing home, contact isolation (to minimize person-to-person spread) and hand washing by health care workers have been shown to limit spread of the virus.
