Background: Picornaviruses, common infectious agents in humans and various animal species, pose significant health threats. Conventional monoplex PCR is widely employed in laboratory diagnostics but is relatively time-intensive and laborious.
Results: In this study, we developed a multiplex TaqMan probe-based real-time quantitative PCR (qPCR) assay for the rapid and simultaneous detection of kobuvirus, parechovirus B, rosavirus B and hunnivirus in murine rodent and shrew samples. The approach demonstrated high sensitivity and specificity, with detection limits of 1 × 10 copies/µL for kobuvirus, parechovirus B, and rosavirus B, and 50 copies/µL for hunnivirus. Evaluation using 149 clinical samples showed strong concordance with conventional PCR methods.
Conclusions: This work developed an effective multiplex qPCR method for the simultaneous detection of emerging picornaviruses particularly in rodents, including kobuvirus, parechovirus B, rosavirus B, and hunnivirus. Our findings contribute valuable insights into the monitoring and prevention of zoonotic diseases associated with these pathogens.

Article Synopsis
- Peru struggled significantly with COVID-19, leading to diminished focus on other endemic viral diseases due to health facility reallocation.
- The One Health approach combines environmental surveillance with clinical testing to detect infectious diseases, emphasizing the need for comprehensive monitoring.
- A study utilized wastewater samples from Trujillo to identify diverse viruses, confirming the presence of multiple human and zoonotic viruses, including SARS-CoV-2 and others through advanced sequencing methods.

Background: Periodic bioinformatics-based screening of wastewater for assessing the diversity of potential human viral pathogens circulating in a given community may help to identify novel or potentially emerging infectious diseases. Any identified contigs related to novel or emerging viruses should be confirmed with targeted wastewater and clinical testing.
Results: During the COVID-19 pandemic, untreated wastewater samples were collected for a 1-year period from the Great Lakes Water Authority Wastewater Treatment Facility in Detroit, MI, USA, and viral population diversity from both centralized interceptor sites and localized neighborhood sewersheds was investigated.

In this investigation, fecal specimens from children with diarrhea were collected from four community studies conducted between 1982 and 2019 in Belém, Brazilian Amazon. A total of 234 samples were tested by quantitative reverse transcription polymerase chain reaction (RT-qPCR) to detect infections by picornaviruses of the Enterovirus (EV), Parechovirus (HPeV), Cosavirus (HCoSV), Kobuvirus (Aichivirus - AiV) and Salivirus (SalV) genera. The positive samples were subjected to different amplification protocols of the VP1 region of the genome, such as nested PCR or snPCR, and were subsequently genotyped by sequencing VP1 and VP3 of the viral genome.
