The FinePointe Cough detector does not formally support Sneeze detection. No direct work with the Cough Detector has been done to mark sneezes separately.
However, when developing the Cough Detector, one of the users was concerned about ensuring only coughs were counted, and they did not want sneezes counted as coughs. We do know that cough and sneeze events look similar. The IsCough parameter is meant to signal when an event is a cough. If we are willing to accept that only coughs and sneezes are captured as events, you could say that all detected events where IsCough is false is a sneeze. But again, this has not been formally validated.
