In August 2016, a community of homeless people in Boston started showing up at a clinic with HIV. By June 2018, the outbreak involved more than 120 people, predominantly in the cities of Lawrence and Lowell in northeastern Massachusetts. The Massachusetts Department of Public Health (MDPH) asked for CDC’s help in investigating and responding to the outbreak.

Ah, summertime at the beach; a time to relish the sun, the sand, and the ocean. Millions of people flock to the seashore each year to enjoy summertime fun. One resort town in New Hampshire draws many visitors from neighboring states each summer to its sandy beaches along the Atlantic shore. But in the summer of 2018, with the town’s annual seafood festival just weeks away, the town faced an unwelcomed visitor. Several people landed in the hospital with a severe form of pneumonia after visiting the town. A team of state, local, and federal investigators leapt into action to find the cause of the illnesses.

Recent research in the Streptococcus Lab (StrepLab) at CDC is improving how scientists identify outbreaks of group A strep infections. While CDC’s scientists were developing the cluster detection tool in 2017, epidemiologists in Minnesota noticed an increase in these kinds of infections. StrepLab’s new technology helped researchers detect and investigate a deadly multi-facility outbreak that might have otherwise been missed.

This year, the PulseNet national laboratory network is transitioning from pulsed-field gel electrophoresis (PFGE) to whole genome sequencing (WGS) to combat foodborne diseases more effectively. PulseNet public health scientists from laboratories across the United States will now have the tools to generate, analyze, and share their WGS results of foodborne bacteria with the other network participants.

Cyclospora cayetanensis is a particularly challenging pathogen to analyze, but thanks to AMD and a prototype typing tool that creates a “DNA fingerprint,” it may become easier for disease detectives to crack the code on Cyclospora outbreaks. CDC scientists are prepared to type samples in real time during the 2019 Cyclospora season to evaluate the new tool’s utility for outbreak detection. With this new tool, researchers hope to assist public health officials to detect more outbreaks and to learn how these pathogens are getting into the food system.

The AMD program has partnered with the CDC Foundation and the Bill and Melinda Gates Foundation (BMGF) on a one-year project to define what software infrastructure is needed to support the complex information workflows required by AMD technologies.
In March, OAMD’s Greg Armstrong and Duncan MacCannell and NCIRD’s Elizabeth Neuhaus met with the project team, which also includes Africa CDC officials, Trevor Bedford’s laboratory at the University of Washington, and a group of experts in bioinformatics and open software development. The group seeks consensus on a sustainable framework for this software—a framework that will facilitate the application of pathogen genomics to public health both in high-income countries such as the United States as well as in low- and middle-income countries.
AMD Director Greg Armstrong said, “It was remarkable how strongly the participants felt about the need for this meeting and for an effort to coordinate the development of software that will support pathogen genomics in public health.”

The Office of Advanced Molecular Detection (OAMD) welcomed epidemiologists and microbiologists from state and local health departments across the nation to the first AMD Academy, hosted with the Association of Public Health Laboratories (APHL) and the Council of State and Territorial Epidemiologists (CSTE). Held in Atlanta during the last week of January, OAMD presented a 2-day molecular epidemiology course for epidemiologists (January 30–31) and a 4-day, intermediate-level bioinformatics course for microbiologists (January 28–31).

On February 14, the Journal of the American Medical Association (JAMA) published an articleexternal icon describing ongoing advances being made by CDC’s Advanced Molecular Detection (AMD) program in the field of next generation sequencing (NGS). JAMA also published a related clinical review podcastexternal icon, where they interviewed two of the authors, Marta Gwinn, MD, MPH, and Gregory L. Armstrong, MD, from the Office of AMD about the potential NGS holds for improving clinical and public health microbiology.
