A public awareness campaign, "Healthy-Secure-Mississippi", seeks to educate Mississippi residents about services that are available in a crisis.
It was launched Tuesday by the Mississippi Department of Health.
Among the additions since 9/11 are 38 centers to respond to a terrorist attack and bio-terrorism training for public health nurses.
"Our programs at the Mississippi Department of Health and Emergency Preparedness Response are nationally recognized and lauded. We've developed a variety of programs and activities to specifically prepare for all emergency events," said state health officer, Dr. Brian Amy.
The department says a public opinion survey showed Mississippi residents view bio-terrorism as the number one health threat.
