An outbreak of African Swine Fever Virus (ASFV) has been reported in La Hispaniola. Ecological niches of transmission and further characterization of vectors involved should be included in a research agenda to reduce the impact on emerging pathogens affecting food security in a previous afflicted region.

The Impact

SUMMARYThe spread of African swine fever virus (ASFV) threatens to reach further parts of Europe. In countries with a large swine production, an outbreak of ASF may result in devastating economic consequences for the swine industry. Simulation models can assist decision makers setting up contingency plans. This creates a need for estimation of parameters. This study presents a new analysis of a previously published study. A full likelihood framework is presented including the impact of model assumptions on the estimated transmission parameters. As animals were only tested every other day, an interpretation was introduced to cover the weighted infectiousness on unobserved days for the individual animals (WIU). Based on our model and the set of assumptions, the within- and between-pen transmission parameters were estimated to βw = 1·05 (95% CI 0·62–1·72), βb = 0·46 (95% CI 0·17–1·00), respectively, and the WIU = 1·00 (95% CI 0–1). Furthermore, we simulated the spread of ASFV within a pig house using a modified SEIR-model to establish the time from infection of one animal until ASFV is detected in the herd. Based on a chosen detection limit of 2·55% equivalent to 10 dead pigs out of 360, the disease would be detected 13–19 days after introduction.

ABSTRACT African swine fever virus (ASFV) is the causative agent of a severe and highly contagious viral disease of pigs that poses serious economic consequences to the swine industry due to the high mortality rate and impact on international trade. There is no effective vaccine to control African swine fever (ASF), and therefore, efficient disease control is dependent on early detection and diagnosis of ASFV. The large size of the ASFV genome (∼180 kb) has historically hindered efforts to rapidly obtain a full-genome sequence. Rapid acquisition of data is critical for characterization of the isolate and to support epidemiological efforts. Here, we investigated the capacity of the Oxford Nanopore MinION sequence sensing device to act as a rapid sequencing tool. When coupled with our novel companion software script, the African swine fever fast analysis sequencing tool (ASF-FAST), the analysis of output data was performed in real time. Complete ASFV genome sequences were generated from cell culture isolates and blood samples obtained from experimentally infected pigs. Removal of the host-methylated DNA from the extracted nucleic acid facilitated rapid ASFV sequence identification, with reads specific to ASFV detected within 6 min after the initiation of sequencing. Regardless of the starting material, sufficient sequence was available for complete genome resolution (up to 100%) within 10 min. Overall, this paper highlights the use of Nanopore sequencing technology in combination with the ASF-FAST software for the purpose of rapid and real-time resolution of the full ASFV genome from a diagnostic sample.

Descriptive Method

The aim of the study is to assess the impact of African swine fever virus (ASF) on the development and functioning of the pork market in Poland. This virus appeared in Poland in February 2014 in wild boars, and then in July 2014 in pigs. The study covers the years 2014-2018, the period of ASF virus in Poland. By the end of July 2018, there were 182 cases of ASF in pigs and over 2.6 thousand in wild boars in four provinces of eastern and central Poland, and the largest cluster of this disease is located in the Lublin province. The appearance of ASF virus has had a negative impact on the pork market in Poland, resulting in restrictions on the export of this meat, costs of eradication of outbreaks and biosecurity. Despite these difficulties, the production of pork at this time was characterized by an upward trend, while exports only in the first year of the ASF decreased, but in subsequent years, due to the diversification of markets, there was an increase in exports. The descriptive method and simple statistical analyzes were used for the study.
