2025 Scientific Reports

The Institute in 2025

The Institut Pasteur du Cambodge (IPC), created in December 1953, is a non-profit research institution operating under the high patronage of the Cambodian Ministry of Health (MoH). Our mission is to contribute to the prevention and treatment of infectious diseases through research, public health activities, and training. This report presents the Institute’s activities in 2025.

 

As of 31 December 2025, the Institute employed 315 personnel (including 51 civil servants attached to the Ministry of Health) representing 17 nationalities. Scientific activities are carried out by more than 60 scientists, each holding at least a PhD or a doctorate degree in medicine, veterinary medicine or pharmacy and another PhD or master’s degree.

 

The IPC’s activities encompass four main categories: (i) biomedical research with a specialization in infectious diseases, (ii) support and capacity building for public health in Cambodia and the Greater Mekong Sub-region, (iii) the provision of health services (laboratory, vaccination), and (iv) training and education. The IPC focuses on infectious diseases and on public health challenges and issues, which include illnesses related to arboviruses, respiratory viruses, rabies, malaria, antimicrobial resistance in microorganisms, and zoonosis, among others.

 

These complex scientific matters, particularly those that involve pathogens with complex life cycles that can involve humans, mammals, and arthropods — studied with a One Health approach — could not be effectively addressed without complementarity between the Institute’s units and specialists (entomologists, doctors, veterinary scientists, immunologists, epidemiologists…).

Scientists can rely on high-level technical platforms to carry out their research and public health activities including a Biosafety Level3 (BSL3) laboratory, sequencing platform, single-cells analysis, biobank and an animal research facility.

 

Research activities done in 2025 were featured in 67 articles published by scientists affiliated to IPC, appearing in peer-reviewed international journals. Among them are 35 (52%) as first or last author and 32 (48%) with an IF greater than or equal to 4.

In 2025, several large-scale projects were implemented in the field by different IPC units, in close collaboration with their partners, following a One Health approach. These notably included PREZODE-AFRICAM, ECOMORE, and RACSMEI.

 

Post-exposure rabies management activities increased slightly in 2025, by 3.4% compared to 2024, with the management of 60,206 patients in our 3 rabies prevention centres (58,203 in 2024). The risks related to rabies indeed remain high in Cambodia: 56 % of the 203 animals tested for rabies virus at the Virology Unit were positive.

 

The IPC plays a major role in the training of university students. Its scientists participate in curricula offered by local universities, including the University of Health Sciences (UHS) in Phnom Penh. Additionally, the IPC itself welcomes many students for internships and practical experiences. During 2025, 138 students interned at the IPC. (154 in 2024). Among these138 students, 105 (76%) were Cambodian nationals, while the others were from France, Marocco, French, Morocco, Pakistani, Cameroon, Bangladesh, Guinean.

 

An ambitious capacity-strengthening policy for young Cambodians was put in place in 2022 (young talents at the IPC), allowing them to carry out their doctorate studies at the IPC (scholarships for non-IPC students and continued salaries for IPC personnel). This policy continued throughout 2025. As a result, 2 Cambodian defend their PhD (Immunology and Epidemiology and Public Health Unit) and IPC hosted 15 PhD student on 31st December 2024 (9 Cambodian and 6 foreigners)

 

Our Health Service activities in 2025 showed an overall favorable trend compared with 2024: (i) activity at the Medical Biology Laboratory declined by 9.4% (5.1 vs. 5.9 million “B”), despite a 2.3% increase in the number of analyses performed (167,627); (ii) the Laboratory of Environment and Food Safety recorded a 1.54% increase in the total number of tests performed (36,312 vs. 35,768); and (iii) the International Vaccination Centre registered a 30% increase in the total number of injections administered, including vaccinations and immunoglobulins (68,530 vs. 53,017).
