Snippet: The limitations of this study include that we did not test for bacterial or viral infection at the time of reported symptoms. This would confirm that an infection was the cause of symptom development and also ensure that no other infections were missed within the 4 weeks.

Document: The limitations of this study include that we did not test for bacterial or viral infection at the time of reported symptoms. This would confirm that an infection was the cause of symptom development and also ensure that no other infections were missed within the 4 weeks.
