The One Health concept promotes the enhancement of human, animal and ecosystem health through multi-sectoral governance support and policies to combat health security threats.

In Vietnam, antimicrobial resistance in animal and human health settings poses a significant threat, but one that could be minimised by adopting a One Health approach to antimicrobial resistance surveillance.

Vietnam is a potential hotspot for the emergence of antimicrobial resistance due to the high burden of infectious diseases that are directly transmissible and that are foodborne, coupled with limited enforcement of regulations to penalise non-compliance, and the relatively unregulated access to antimicrobials for humans and high antimicrobial usage for livestock.

To advance understanding of the willingness and abilities of the human and animal health sectors to investigate antimicrobial resistance through a One Health approach, a recent study published in BMC Public Health (February 2020) explored the perceptions and experiences of those tasked with investigating antimicrobial resistance in Vietnam, and the benefits a multi-sectoral approach offers.

The study used qualitative methods to provide key informants’ perspectives from the animal and human health sectors. Two scenarios of foodborne antimicrobial resistance bacteria found within the pork value chain were used as case studies to investigate challenges and opportunities for improving collaboration across different stakeholders and to understand benefits offered by a One Health approach surveillance system.

Fifteen semi-structured interviews with 11 participants from the animal and six from the human health sectors at the central level in Hanoi and the provincial level in Thai Nguyen were conducted.

Eight themes emerged from the transcripts of the interviews. From the participants’ perspectives on the benefits of a One Health approach: (1) communication and multi-sectoral collaboration, (2) building comprehensive knowledge and (3) improving likelihood of success. Five themes emerged from participants’ views of the challenges to investigate antimicrobial resistance: (4) diagnostic capacity, (5) availability and access to antibiotics, (6) tracing ability within the Vietnamese food chain, (7) personal benefits and (8) Managing the system.

The findings of the study suggest that there is potential to strengthen multi-sectoral collaboration between the animal and human health sectors in Vietnam by building on existing informal networks.

Based on these results, the authors of the study recommend an inclusive approach to multi-sectoral communication supported by government network activities to facilitate partnerships and create cross-disciplinary awareness and participation.

The themes relating to diagnostic capacity show that both the animal and human health sectors face challenges in carrying out investigations on antimicrobial resistance although based on the results, there is a greater need to strengthen the animal health sector.

Dengue fever is a mosquito-borne viral disease that commonly occurs in warm, tropical climates. It is characterized by high fever and flu-like symptoms that can last for up to one week. In a small proportion of cases, severe dengue may occur, leading to bleeding and low blood pressure. There is no specific treatment for infection but medication can be taken to control symptoms.

Climate change and rapid unplanned urbanization are among the factors that have brought people into more frequent contact with the vectors, thus contributing to further spread of disease.

According to the World Health Organization, the global incidence of dengue has risen dramatically in recent decades, with an estimated 390 million dengue infections annually.

Vietnam is one of at least 100 countries where the disease is now endemic. Dengue infection in Vietnam is unstable but peaks from June to October annually.

As part of efforts to curb the spread of dengue in Vietnam, research efforts are being undertaken to develop tools that will enable timely detection and control of the disease. One such research study recently examined seasonal trends of dengue in Vietnam and used the data to develop a statistical model to forecast the incidence of the disease.

The study, published in PLOS ONE (27 Nov 2019), was carried out by a team of researchers from the International Livestock Research Institute and Vietnamese partners from Hanoi University of Public Health, the Institute of Meteorology, Hydrology and Climate Change, the Ministry of Health and the National Institute of Hygiene and Epidemiology.

To develop the statistical risk forecasting model, the researchers used dengue surveillance data that had been collected by health centres in Vietnam’s 63 provinces between 2001 and 2012. In addition, they obtained monthly meteorological data from the Institute of Meteorology and Hydrology and Climate Change. Land cover data were obtained from the Moderate Resolution Imaging Spectroradiometer website of the United States National Aeronautics and Space Administration.

The data were also used to develop risk maps of dengue incidence showing the distribution of the incidence of infection in the wet and dry seasons. The researchers are optimistic that with these new risk-based forecasting tools, policymakers and planners in Vietnam will be better able to predict dengue incidence in the country and thus respond in a timely manner to effectively control the disease.

A two-year project that will assess veterinary health management and veterinary drug use in Vietnamese pig farms has been launched.

The Health and Antibiotics in the Vietnamese Pig Production Project, known as VIDAPIG, is a collaboration between the University of Copenhagen, the National Institute of Veterinary Research, the National Institute of Nutrition and the International Livestock Research Institute (ILRI).

It will carry out research to identify and evaluate factors affecting veterinary health and veterinary drug use with the aim of establishing antimicrobial usage practices that are based on a One Health approach across the smallholder pig sector.

The project will be implemented from February 2018 to January 2020 in Bac Ninh Province.

A new initiative that will address growing food safety concerns in Cambodia was recently unveiled in the country.

Funded by the United States Agency for International Development (USAID) under the Feed the Future Innovation Lab for Livestock Systems (LSIL), the ‘Safe Food Fair Food for Cambodia’ (SFFF Cambodia) project kicked off in a workshop held in Phnom Penh on 31 August and 1 September 2017.

The event brought together all the LSIL beneficiaries in Cambodia (on 31 August) and it was followed by an innovation platform (IP) meeting (on 1 September) that was attended by representatives from USAID, the government of Cambodia, research institutes and universities from Cambodia and the United States, researchers from the International Livestock Research Institute (ILRI), and local and international livestock experts.
