2. •NCEZID studies diseases caused by highly hazardous
bacteria (like anthrax) and viruses (like Ebola). For
example, scientists continue to conduct follow-up studies
with survivors of the 2014-2016 West Africa Ebola
epidemic to learn what long-term symptoms they may
face, how long the virus can persist and certain body
fluids, and why some people are better able to survive
Ebola.
•NCEZID scientists also investigate unexplained illnesses
and deaths. This work has led to the identification of new
infectious diseases, such as SARS and hantavirus
pulmonary syndrome.
