CDC at Work: Mycotic Diseases Branch

CDC’s lead group for preventing illness and death from fungal diseases in the United States and throughout the world.

About us

The goal of CDC’s Mycotic Disease Branch (MDB) is to prevent illness and death from fungal diseases. We are one of the only public health groups in the world devoted to the prevention and control of fungal diseases. We work with partners to understand who gets fungal infections and why by using epidemiology and microbiology research. We also investigate outbreaks and develop interventions to prevent fungal diseases.

Mycotic Diseases Branch Teams

Our epidemiology and laboratory teams work together, along with domestic and international partners, to combat fungal diseases in the following ways:

  • Generate new information about fungal diseases and disease-causing fungi
  • Respond quickly to fungal disease outbreaks and other emerging issues
  • Conduct research
  • Provide training and education about fungal diseases

Epidemiology team

Our epidemiologists:

  • Determine the number of people who get sick from fungal diseases
  • Track trends and patterns in how fungal diseases affect people
  • Promote education and awareness about fungal diseases
  • Develop and evaluate ways to prevent fungal diseases
  • Help prepare healthcare facilities and laboratories in other countries to better detect and treat fungal diseases

Laboratory Team

Our laboratory staff:

  • Find and identify disease-causing fungi in patient and environmental specimens (please see our specimen submission information webpage for details)
  • Perform tests on certain specimens to see if they are resistant to antifungal medicines
  • Research and develop new detection, diagnostic, and subtyping methods
  • Use whole genome sequencing to study how and why certain fungi spread and make people sick
  • Conduct a yearly mold identification training course in collaboration with the Association of Public Health Laboratories
  • Help other laboratories improve their abilities to test for certain fungi

Fungal Disease Outbreaks

Fungal disease outbreaks are rare. An outbreak occurs when two or more people get sick from contact with the same source, sometimes in the same time or place. This can happen outdoors or in a health care setting, such as a hospital.

Detecting fungal outbreaks early is important so that the people affected can get the right treatment and so that health officials can prevent others from getting sick.

International Activities

Our branch has assisted in the onsite development, execution, analysis, and publication of numerous studies all over the globe. We work with many international partners in a wide variety of areas, particularly with the assessment and prevention of opportunistic fungal infections among persons with HIV/AIDS. For example, we are working with public health and healthcare agencies in several countries to implement programs that aim to reduce the burden of cryptococcal disease.

For more information about our international work, please visit our Global Fungal Diseases web page.

Below is a map of some of the places we’ve worked during the last 5 years:

Argentina, Australia, Bangladesh, Botswana, Brazil, Canada, Colombia, El Salvador, Ethiopia, France, French Guyana, Ghana, Guatemala, Haiti, Honduras, India, Japan, Lesotho, Malawi, Mexico, Mozambique, Namibia, Nigeria, Pakistan, Rwanda, South Africa, Spain, Suriname, Swaziland, Tanzania, Thailand, Uganda, U.S., Vietnam, Zambia, Zimbabwe

Sharing scientific findings is an important part of the prevention and control of fungal diseases. Our branch is involved in producing numerous articles and papers which detail our research findings and investigations.
