The study revealed that the level of contamination on goat carcasses in Lilongwe was extremely high exceeding the acceptable international standards for swab values which are <2.8 log CFU/cm2 for TVC, and the unacceptable values are >4.3 log CFU/cm2.

In the present study, rectal swab Ct values correlated significantly with faeces Ct values for all targets, with R ranging from 0.31 to 0.85.
In addition, Ct values of enteroviruses from throat swabs were significantly lower, indicating higher viral loads, compared to nasal swabs (median Ct value of throat swab was 30.8 (IQR 28.2 33.7) versus median Ct value of nasal swab 34.6 (IQR 33 37.1), p = 0.003).
The factors investigated included: transport medium, decontamination method, inoculation media, swab qPCR Ct value, patient qPCR result, the time from sampling to inoculation and the number of weeks before diagnosis as reported by the patient.

Of the 12 samples that tested positive by viral culture, five were throat swab samples with Ct values from 25.28 to 31.76, and seven were sputum samples with Ct values from 16.68 to 27.20; these values were lower than the median Ct value for all samples.

PCR cycle threshold values for swab specimens were from 30 to 40, indicating low viral loads.
In contrast, betaglobin was detected in all rectal swab samples with Ct values ranging from 25 to 35 (mean 30), indicating relatively high cell content.
