We've seen images where quite clearly they are not protected properly. We see people with bare hands, their eyes, their nose and their mouth uncovered, where they are possibly breathing in virus,
But we don't know what this means for humans. We don't know if they would play a role in transmitting the disease. We don't know how much virus the cats would excrete, how much people would need to be exposed to before they would fall ill.
There are no other suspect cases. There aren't any other people under observation.
I think really, (illness in) people like health-care workers and first responders would be our first indication that something is changing in the virus to make it more transmissible.
There have been three deaths, with symptoms somewhat similar to H5N1 infection. Other people are still in hospital, including one who is very sick.
