My position on this hasn't changed much in the past five months.
The flu is spreading rapidly among birds but not among people. That increases the chances for a successful mutation to enable human to human transmission, so the threat is becoming more probable.
But it still doesn't make it certain, and it doesn't tell us anything about how deadly the human to human transmission will be.
It's a huge unknown, and the range of possibilities extends from small threat to global disaster, and we won't be able to make that determination until it's clearly one or the other.
Did you read the couple of articles lately on FR about how less than a year ago 8 mutations were needed to go H2H, and now only 2 are needed?
I am not paying as much attention to this as I was a while ago, since winter's nearing its end. But I want to remain alert and stay informed. The world is a dangerous place and bad things do happen. Being a pollyanna is not my style, nor is digging a giant hole, climbing in and pulling it in after me.
