Yes but just because someone in your house has a cold doesn’t mean you are going to get it. What they say is they don’t have proof it can be caught by air, but that doesn’t mean it isn’t happening and I would say this nurse who got it certainly wasn’t messing with drops of blood or vomit. It sounds to me like as she was taking off her suit she breathed it in unless she had some open wound on her body. The bottom line is this isn’t “just like AIDS” as they were comparing it to. This can be caught much more easily.
Most likely in the nose or eyes. But it has to be a droplet, not just aerosolized virus. There is definitely a difference. Some nurses in Dallas would have had more viral liquids on them than others. It would be good to know how much she had. Was she tasked with intubating anywhere? Was she cleaning up the patient?
