National Center for Emerging and Zoonotic Infectious Diseases

**Our mission** The National Center for Emerging and Zoonotic Infectious Diseases (NCEZID) was established in 2010, with a mission and scientific activities that trace back to CDC's earliest days. We are responsible for the prevention and control of a wide range of infectious diseases. This includes rare but deadly diseases like anthrax and Ebola, and more common illnesses like foodborne diseases and healthcare-associated infections. **Infectious Diseases** **Infectious diseases**?are illnesses caused by germs that enter the body, multiply, and can cause an infection. Bacteria, viruses, and fungi can cause infectious diseases. Infectious diseases can spread 1. Between people 2. Between people and animals 3. Through vectors (like biting insects) 4. Through food, water, and the environment **Why it's important** Infectious diseases can spread quickly and quietly before an outbreak is found. NCEZID works to detect these outbreaks faster to limit the spread. Our work includes common diseases like *Salmonella* and *Staphylococcus* as well as emerging diseases like Marburg virus disease, monkeypox, and drug-resistant fungal infections. Infectious disease outbreaks cost money and lives, which is why preventing outbreaks is one of our most important roles. **Our work** To carry out our mission, we use many different tactics. We provide leadership in public health, conduct science, strengthen preparedness efforts, establish public health policy, share vital health information with the public, and build partnerships. NCEZID works to build and strengthen public health capacity and readiness to address disease threats, including - Foodborne, waterborne, and fungal diseases - Antimicrobial-resistant infections - Infections spread in healthcare settings - Deadly diseases like Ebola, rabies, and anthrax - Illnesses that affect immigrants, migrants, refugees, and travelers - Diseases spread by mosquitoes, ticks, and fleas - Infections due to parasites like malaria - Diseases that spread between people, animals, and their environments - New diseases in the United States, like Zika and monkeypox - Innovations for combatting infectious diseases, including wastewater surveillance, travelers' genomic sequencing, and advanced molecular detection NCEZID also does important work contributing to the development of more effective vaccines, therapeutic drugs, and tools to diagnose diseases.
