For such eggs, if they are kept in cold, dry storage for half to one month, they may still be used, because that would kill the virus. Or you wash the egg.

It has no disease control system. This virus can infect not only birds, but other animals too,

Many countries use vaccines and think the virus is completely exterminated ... but this problem is still in southeast Asia. It's even in migratory birds and they are dying. Why? Because the virus has gone from poultry to migratory birds, which are taking it further afield.

We really have no idea what is going on now in southern China.

This means out of every 100 birds in wet markets, one is positive and infected with the virus. They look healthy but they can infect others and they can kill people.

Of course it has been a failure. If it was a success, we wouldn't have come to this.
