Infectious Diseases Overview

Public health laboratories are always on the lookout for new and re-emerging infectious diseases to help limit their spread and keep us healthy. APHL builds public health laboratory capability to detect, identify and respond to infectious disease threats.

Detecting and Preventing Infectious Threats

The work of the public health laboratory never ends. Our public health laboratories are prepared to protect our communities from invisible threats—ranging from seasonal influenza to multidrug resistant organisms and emerging threats like Oropouche virus. Through continuous monitoring, diagnostic testing and their ability to perform advanced characterization testing, public health laboratories detect and respond to new and re-emerging diseases swiftly, providing data and communicating information to improve our understanding of disease transmission.

What APHL Does

Supporting a Responsive Laboratory System

APHL provides programming and technical assistance to improve public health laboratory infectious diseases testing, surveillance and response capability and practice nationally. We support public health laboratories and partners to ensure a responsive laboratory system and improve efficiency and operational effectiveness for infectious disease testing.

Strengthening Infectious Disease Testing Domestically and Globally

APHL facilitates the evaluation of new methods and technology to improve detection and/or diagnosis of infectious diseases through partnership with CDC and the public health laboratory community.

APHL collaborates and builds relationships among laboratory professionals and partners in public health, healthcare and beyond to facilitate information exchange and dissemination among them. This includes work across all infectious diseases and ongoing workgroups, such as the APHL-ASM Antimicrobial Laboratory Workgroup or supporting the AMD Communities of Practice.

In response to the changing landscape and public health laboratory needs, APHL has established six different Reference Centers based on a shared service model for ensuing all public health laboratories have access to the high-quality testing. The Reference Centers have been established for National Influenza Surveillance, Legionella, HIV and HCV Nucleic Acid Testing, drug susceptibility testing for Mycobacterium tuberculosis and for several viral and bacterial vaccine preventable diseases. APHL continues to monitor the need for additional testing services in a Reference Center Model.

To learn more visit the pathogen specific pages for Reference Center information including eligibility, enrollment and services offered:

  • HIV: HIV NAT Reference Center
  • Viral Hepatitis: HCV NAT Reference Center
  • Respiratory Diseases:
  • National Influenza Reference Center
  • Legionella Reference Center
  • Vaccine Preventable Diseases: Vaccine Preventable Diseases
  • Tuberculosis: TB DST Ref Center

APHL has been actively engaged in global initiatives to support infectious disease testing in collaboration with CDC partners.

  • Laboratory Capacity Assessments: APHL supports the development and maintenance of National Influenza Centers, a cornerstone of the Global Influenza Surveillance and Response System (GISRS), one of the longest running surveillance programs globally. APHL and CDC developed the International Influenza Laboratory Capacity Review Tool which is used to perform voluntary laboratory capacity assessments where for subject matter experts from US public health laboratories and CDC observe laboratory operations and capture information to understand laboratory specific gaps and training needs. Similar tools have also been developed based on this concept to help provide feedback to other countries on their laboratory capacity beyond influenza virus.
  • Training Workshops: APHL coordinates regional training workshops to support laboratories around the world. Trainings are typically held regionally and may be didactic or hands-on wet-laboratory training. Courses are tailored to specific regional needs, which may have been previously identified through laboratory capacity assessments or other site visits.
  • Mentorship: APHL has established a quality assurance mentoring program which paired mentors from US public health laboratories with scientists at national laboratories focused on influenza testing to assist them as they worked to attain National Influenza Center status. The mentors shared examples of standard operation procedure templates and other example documents with assigned mentee countries and other countries in the region. The laboratories used the WHO Laboratory Quality Stepwise Implementation tool​ to help guide the development of quality management systems.

Shaping Infectious Disease Laboratory Policy and Practice

APHL develops and shares guidance, information, tools and resources that promote quality infectious disease testing policy and practice. Listed below are examples of this work.

Providing Educational Opportunities in Infectious Diseases for Public Health, Veterinary Diagnostic and Clinical Laboratories

APHL sponsors a variety of educational and training in multiple formats to accommodate the demanding schedules of our professionals. We support and sponsor hands-on trainings for pathogen and test method specific workshops, our Spring and Fall Infectious Diseases Webinar Series are held live for Q&A and recorded for later viewing, on-demand trainings are available on the APHL Learning Center,  and just-in-time webinars as well as a monthly National Infectious Diseases Issues Call (see ‘Communications and Publications’ below).

Visit the ID Resources and Training page

APHL also administers a laboratory fellowship program, which includes an infectious diseases focus area. The fellowship aims to train and prepare recent graduates to apply their scientific expertise challenges within the public health laboratories and programs. Fellows gain hands-on experience in testing, surveillance and data analysis, contributing to efforts that strengthen the nation’s capacity to detect and respond to infectious diseases. Applications are accepted on a rolling basis.

Supporting Public Health Laboratory Responses to Infectious Diseases 

During public health responses, APHL coordinates, disseminates information and ensures appropriate guidance is developed in partnership with public health laboratories and federal partners.
