It is the lie of omission. It is the truth that the patient did not have the usual influenza symptoms, and the symptoms associated with the dairy virus, but they know that the symptoms that were expressed have been associated with the Asian H5N1 human infections that resulted in a high mortality among those infected. Instead of being nothing to worry about and the claims that it is a "one off" type of infection. These symptoms could be evidence that the virus is changing to become more pathogenic in humans, and is evidence for human to human transmission because this patient did not have contact with farm animals.
