Thousands of frozen bovine semen doses are produced daily in the US for domestic use. An incursion of foot-and-mouth disease (FMD) in the country would pose strong challenges to the movements of animals and animal products between premises. Secure supply plans require an estimation of the risk associated with target commodities and the effectivenes...

Background The FAIR (Findable, Accessible, Interoperable, Reusable) principles were proposed in 2016 to set a path towards reusability of research datasets. In this systematic review, we assessed the FAIRness of datasets associated with peer-reviewed articles in veterinary epidemiology research published since 2017, specifically looking at salmonid...

The fish production, health and management data routinely collected on aquaculture farms represent a significant resource that could better support epidemiological research than traditional surveys and other studies. To this aim, a collaborative data integration platform was developed in late 2017 with the Chilean salmon and trout production indust...

African swine fever (ASF) is an infectious disease of swine causing major losses in the swine industry worldwide. Early detection of ASF is challenging because of the wide range of nonspecific clinical signs produced and its relatively low contagiousness. Monitoring pig mortality is a promising approach for early detection of ASF but such approach...

Seasonal variations in COVID-19 incidence have been suggested as a potentially important factor in the future trajectory of the pandemic. Using global line-list data on COVID-19 cases reported until 17th of March 2020 and global gridded weather data, we assessed the effects of air temperature and relative humidity on the daily incidence of confirme...

Sea lice infestation is a chronic production issue for the majority of salmonid farming industries worldwide. In Chile, Caligus rogercresseyi is the main sea lice species of concern. It is associated with poor welfare, reduced productivity, high treatment and management costs, and increased susceptibility to other diseases within the salmonid aquac...

Although the bacterium Piscirickettsia salmonis has been detected in many salmon-producing countries around the world, losses caused by salmonid rickettsial septicaemia (SRS) are mostly occurring in the Chilean aquaculture industry. Horizontal transmission of SRS between salmonid farms was suggested, based on the existence of spatiotemporal correla...

The presence of free-grazing ducks (FGD) has consistently been shown to be associated with highly pathogenic avian influenza virus (HPAIV) H5N1 outbreaks in South-East Asia. However, the lack of knowledge about the transmission pathways limits the effectiveness of control efforts. To address this gap, we developed a probabilistic transmission model...

Early detection surveillance is used for various purposes, including the early detection of non‐communicable diseases (e.g., cancer screening), of unusual increases of disease frequency (e.g., influenza or pertussis outbreaks), and the first occurrence of a disease in a previously free population. This latter purpose is particularly important due t...

Salmon rickettsial septicaemia (SRS, or piscirickettsiosis) is a major disease of the Chilean salmonid aquaculture industry. Although numerous vaccines for SRS are currently registered for use in Chile, there is little evidence of their effectiveness under field conditions. In this study, we aimed to quantify the effectiveness of different vaccinat...

Salmonid rickettsial septicaemia (SRS) is the most important disease of farmed salmonid fish in Chile and the main driver of a high rate of antimicrobial use. This study evaluated the effectiveness of antimicrobial treatment of SRS outbreaks, using industry-generated data from 8318 cage-level production cycles stocked between 2003 and 2018. We defi...

The bacterial disease salmonid rickettsial septicaemia (SRS) has caused substantial economic losses in the salmonid aquaculture industry, particularly in Chile. Increasing understanding of the epidemiology of this disease is important for improving the productivity and sustainability of the industry: by identifying important influences on disease o...

Seasonal variation in COVID-19 incidence could impact the trajectory of the pandemic. Using global line-list data on COVID-19 cases reported until 29th February 2020 and global gridded temperature data, and after adjusting for surveillance capacity and time since first imported case, higher average temperature was strongly associated with lower COV...

Salmonid rickettsial septicaemia (SRS) has caused significant losses in the Chilean salmonid aquaculture industry in the last two decades. While evidence suggests a strong association between sea lice burden and SRS severity, research to date has been conducted in tanks under controlled environmental conditions. Further, existing work does not acco...

In light of the various adverse effects of Johne's disease on animal productivity and the debate on the role of its causative organism, Mycobacterium avium ssp. paratuberculosis, in the etiology of Crohn's disease, major dairy-producing countries around the world have implemented national control programs aimed at reducing the prevalence of this in...

Live bird markets (LBMs) are major targets for avian influenza virus (AIV) surveillance programmes. While sampling the LBM environment has become a widely used alternative to the labour-intensive sampling of live poultry, the design of surveillance programmes and the interpretation of their results are compromised by the lack of knowledge about the...

Estimation of animal weight is critical in cattle production to assist in herd management and to estimate the value chain prices of the animals. There is a lack of tools for small-scale farmers and stakeholders to readily estimate cattle weight in communal livestock farming systems in South Africa. Models found in the literature cannot be easily ad...

Epidemiology provides insights about causes of diseases and how to control them, and is powered by surveillance information. Animal health surveillance systems typically have been designed to meet high-level government informational needs, and any incentives for those who generate data (such as animal owners and animal health workers) to report sur...

Highly pathogenic avian influenza (HPAI) H5N1 virus has been circulating in Vietnam since 2003, whilst outbreaks of HPAI H5N6 virus are more recent, having only been reported since 2014. Although the spatial distribution of H5N1 outbreaks and risk factors for virus occurrence has been extensively studied, there have been no comparative studies for...

Background: Animal African trypanosomiasis (AAT) and its tsetse vector are responsible for annual losses estimated in billions of US dollars ($). Recent years have seen the implementation of a series of multinational interventions. However, actors of AAT control face complex resource allocation decisions due to the geographical range of AAT, diver...

Brucellosis is a neglected endemic zoonosis in West and Central Africa. In this narrative review, evidence of livestock and human infection is presented along with details of past and current control strategies in 14 selected countries.

Johne's disease is a serious wasting disease of ruminants that is of high economic importance for the dairy sector in particular. The chronic nature of the disease, the fluctuations in antibody levels and the limited ability of diagnostic tests to identify cows at early stages of infection are huge challenges for the control of the disease. In the...

Highly pathogenic avian influenza (HPAI) viruses continue to threaten smallholder poultry producers in several Southeast Asian countries, including Vietnam. In particular , the free-grazing duck system has been repeatedly highlighted as a major risk factor for HPAI outbreaks. Free-grazing ducks, which scavenge on rice paddies after the harvest, acc...

Presence of ducks, and in particular of free-grazing ducks, has consistently been shown to be one of the most important risk factors for highly pathogenic avian influenza outbreaks which has compromised poultry production in South-East Asia since the early 2000s and continues to threaten public health, farmers’ livelihood and food security. Althoug...
