Four people on dairy farms have contracted the disease, but small farms exist in a regulatory no-man’s-land.

Some people mistakenly think raw milk could protect against bird flu. Instead, they could infect themselves, giving the virus a better chance to mutate for rapid human-to-human transmission.
