Law Article Discussion

Below is a link to a news article about a recent issue at one of New Hampshire's largest Hospitals. It was discovered by hospital administration that a patient was infected with a rare brain disease Creutzfeldt-Jakob Disease that can be transmitted surgical tools no matter how well the tools are sterilized. Upon discovery the Hospital contacted the Centers for Disease control, called the patients it believed were exposed and held a press conference.
Did the hospital do the right thing?
In taking the action they did has the hospital prevented any liability under state or federal law to the patients affected?

Please discuss.

- I just need a comment (250 words is enough) for this article, which must be covered the questions I asked and also do some research like example I provide in the attached file.
