A strain of bird flu known as H5N1 or highly pathogenic avian influenza has made a worrying leap to cattle herds across the US over the past month. This development has sparked “enormous concern” among health experts, including the World Health Organization’s (WHO) chief scientist, who warned of the virus’ “extremely high” mortality rate in humans.
Unfortunately there is not a prophylactic vaccine available yet. Even if there was one we are talking about potentially hundreds of millions of dead in developing countries who would not have access to it immediately. I’m not trying to be a doomer, but I think the concern is warranted.
