In a potential outbreak, is bird flu testing available for humans? What to know

Currently, H5N1 avian influenza (bird flu) testing is provided only by governmental health departments. Here's what to know in the event of a human outbreak of bird flu....                        ...                        ...                            ...Several people have tested positive for bird flu in the U.S., raising questions about the availability of tests in the event of a You are not allowed to view links.
