“I have never seen a case of [Influenza] Type A followed by Type B right off,” said Dr. Honaker. “The immune system should kick in with Type A so you don’t get Type B, and this year we are seeing people in my office who have Type A and two or three weeks later they have type B.”
This is an anecdotal report from a physician in North Texas. An adequately powered study will need to be conducted before we can be sure that Dr. Honaker’s impression is true. However, given that there have been previous reports that pH1N1 is associated with immune system dysfunction, this issue deserves additional scrutiny.
