Lets not be ridiculous. One of the people that works in the lab in Wuhan is widely known by virologists all over the world. She publishes widely and her work is widely respected. When you publish you are telling the world what you are doing and why. Virologists collect viruses from nature. That's where they get them. We know already that when they study viruses found in mammals they get them from mammals. But of course, in general, viruses have evolved to infect only specific species so a virus collected in bat caves, for example, would not, in general, pose a danger to other mammals. It's amazing how rapidly China was able to identify the cause of the disease breakout in Wuhan and notify the world! Do you think that when China reacted to a serious disease outbreak that people all over the world did not know about it very soon thereafter regardless of whether China made a formal announcement. Of course we in the U.S. and other developed countries knew about the disease outbreak. In fact the U.S. intelligence community knew about the outbreak in early January and notice of this was included in the president's daily briefings. But China could not notify anyone regarding the specific cause of the infections until they themselves knew. Lets suppose you are working in internal medicine and you have patients coming down with what appears to be a viral respiratory disease that is not showing a positive test for well known influenza viruses and is unresponsive to standard treatments. How long would it be until you had identified the specific agent causing the disease? Do you recall how long it took to identify the retro virus that caused human immunodeficiency disease? Perhaps you will recall their was a Nobel Prize awarded for that! That's very likely why there was a delay in identifying the disease agent involved in the Wuhan outbreak. These things are not easy to do. In retrospect, the rapidity with which China was able to respond is amazing! You're asking the wrong question. The question you should be asking is why did the U.S. take so long to react once it knew that the outbreak was caused by a new virus. I have a question for you specifically. Do you think that President Trump's attempts to blame China for the outbreak of Covid disease in the Western countries is going to help or hurt international cooperation among virologists and facilitate or hinder the exchange of virologists, cooperative research agreements among laboratories and the free exchange of information? I don't know if you are aware of this, but the particular strain of Covid in the NY patients came from Europe, and at least not directly from China. As I pointed out previously, a viruses genetics reveal its ancestors. A viruses genetics are incapable of lying the way presidents do.
