I'm not a Virologist, nor any medically trained discipline. I am merely a lowly student of history. The Scientific community has been categorically wrong on many issues throughout history. The more we learn, the more we begin to understand that we know extremely little. Science is about learning about ourselves and the world around us. To be a great scientist, you have to eliminate preconceived notions and biases. Observe, Analyze, Postulate, Theorize, Test and then Conclude. Then find alternate explanations for every Conclusion and ratify or disprove the alternates.
