Avian influenza, or H5N1, is an extremely contagious and deadly respiratory virus for birds.

In milk, pasteurization inactivates the virus, making commercially produced milk safe for consumption.

Eggs from backyard flocks that have direct contact with migrating waterfowl might be more concerning, but avian influenza generally hampers egg production.

Avian influenza is circulating widely among wild birds across more than 170 species.

Of the 70 human cases confirmed in the U.S. so far, most have been in farmworkers.

Scientists don't think there have been cases of human-to-human transmission yet, but research suggests that it could be possible if the virus mutates.

The U.S. is putting $100 million toward research on vaccines and therapeutics for poultry.

The USDA announced an additional $1 billion plan to address bird flu last month .

Researchers are in the process of testing vaccines for cows, too.

How long until egg prices fall depends on how quickly officials can get the outbreak under control.
