She also has provided technical assistance on Nipah virus and Crimean Congo hemorrhagic fever in Bangladesh and Kazakhstan, respectively. And she organized a discussion among state and territorial epidemiologists about hantavirus surveillance, as well as performed studies on the virus and authored a hantavirus review article that appeared in the December 2013 issue of Emerging Infectious Diseases. 

Dr. Knust was recognized for accomplishments over the past year and for exemplary officership and professional development.
