Seroprevalence of African Swine Fever Virus and Farm Management Practices in Nepal: A Cross-Sectional Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAfrican swine fever (ASF) is a contagious fatal viral disease of pigs caused by ASF virus (ASFV). Since its introduction into Nepal in 2022, ASF has caused major losses to pig farmers. However, information on the seroprevalence and associated risk factors in Nepal remains limited, and this study represents the first systematic investigation of ASFV seroprevalence and farm management practices in the country.
objectivesTo determine the seroprevalence of ASF in domestic pigs and slaughterhouse in Nepal and to identify farm management practices that contribute to disease transmission. MATERIALS AND
methodsA cross-sectional study was conducted across pig farms in Bagmati Province. A total of 324 serum samples were collected and tested for ASFV antibodies using competitive ELISA. Additionally, 43 farmers were interviewed to assess management practices and biosecurity measures. Data were analysed using Chi-square and Fisher's exact tests.
resultsOf the 324 samples screened, seven tested positive, with an overall seroprevalence of 2.16%. Seropositivity was detected in multiple districts, but no significant differences were observed by location, sample source, sex, or age group (p > 0.05). The survey revealed poor biosecurity practices: only 6.9% of farmers used protective clothing, 27.9% used foot dips, and 62.8% did not quarantine new animals. Swill feeding was common (34.9%), while 39.5% of farmers used both swill and commercial feed. Improper carcass disposal and sale of sick or dead pigs were also reported.
conclusionsDetection of ASFV antibodies in slaughtered and farm pigs indicates ongoing circulation of the virus in Nepal. Combined with poor farm-level biosecurity, this underscores the urgent need for preventive measures, including strengthened surveillance, farmer awareness, and enforcement of swill-feeding bans, to safeguard Nepal's pig industry.
