CDC in Cambodia

A triage system was set up at Siem Reap Provincial Hospital in March 2020 after identifying a case-contact who tested positive for COVID-19.

The Centers for Disease Control and Prevention (CDC) established an office in the Kingdom of Cambodia in 2002. CDC works with the country’s Ministry of Health (MOH) and local and international partners to address HIV/AIDS, malaria, influenza, COVID-19, and other respiratory illnesses and infectious diseases. CDC’s partnership with the MOH strengthens Cambodia’s laboratory, surveillance, and workforce capacities to prevent, detect, and rapidly respond to disease outbreaks and other public health threats.

CDC Impact in Cambodia

Global Health Security

Resilient public health systems can rapidly prevent, detect, and respond to infectious disease threats before they become epidemics. CDC’s team in Cambodia works to enhance the country’s ability to respond to public health emergencies and strengthen workforce capacity. CDC also played a key role in the MOH’s response to the COVID-19 pandemic.

Through December 2023, the Field Epidemiology Training Program (FETP) has graduated 225 frontline trainees, among whom 10 have completed the intermediate course. These epidemiologists detect, prevent, and control diseases before they become epidemics.

CDC Cambodia supports the Cambodian Applied Veterinary Epidemiology Training (CAVET) program. CAVET’s 75 graduates respond to zoonotic disease outbreaks.


CDC works with the MOH to build a sustainable HIV response program. Cambodia strives to sustain epidemic control and eliminate HIV as a public health threat.  CDC focuses on:

  • Finding people with undiagnosed HIV and placing them on treatment
  • Ensuring treatment continuity and client-centered services for all, including children and adolescents
  • Developing an HIV case-based surveillance system for monitoring treatment and viral load suppression, and for using real-time data from HIV recency testing to find and respond to outbreaks
  • Improving laboratory systems to detect and monitor HIV viral load
  • Adopting and ensuring nationwide implementation of international HIV policies
  • Supporting the national HIV and TB control programs to ensure that people living with HIV are screened for TB and receive TB preventive treatment

Through the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR), CDC is working with Cambodia to end HIV as a public health threat by 2025.

Laboratory Capacity Building

CDC helps strengthen the quality of laboratory systems in Cambodia to accurately diagnose, monitor, and treat infections, including HIV, SARS-CoV-2, influenza, and other respiratory pathogens. CDC also helped implement a laboratory quality management system and is supporting provincial HIV laboratories to achieve international accreditation.

With technical support from CDC, the Cambodian National Public Health Laboratory (NPHL) received International Organization for Standardization (ISO) 15189 Plus™ accreditation in 2019 and was re- certified in 2023.


Through the U.S. President’s Malaria Initiative (PMI), CDC and USAID support Cambodia’s National Center for Parasitology, Entomology and Malaria to pilot and expand malaria elimination activities in Western Cambodia. PMI supports the National Malaria Elimination Action Framework to scale up control and elimination activities for a malaria-free Cambodia by 2025. CDC and partners provide:

  • Technical support for surveillance (antimalarial drug resistance and insecticide resistance)
  • Case management
  • Supply chain management
  • Vector monitoring
  • Social and behavior change communication

CDC malaria work in Cambodia, as part of the U.S. President’s Malaria Initiative with USAID, includes surveillance, vector monitoring, case management, and social and behavior change communication.


CDC works with the Cambodian government and other partners to conduct influenza sentinel surveillance and build laboratory and response capacity. The network monitors seasonal influenza and detects novel influenza viruses among persons with respiratory disease. The platform has been expanded to test for SARS-CoV-2 and respiratory syncytial virus (RSV). Cambodia contributes to the World Health Organization (WHO) Global Influenza Network and global genomic surveillance of SARS-CoV-2.
