“…The distribution of EV species in our study ( Figure 4 ) was similar to that observed in many countries of the world in different climatic zones according to the results of AFP surveillance [ 31 , 32 , 34 , 36 , 37 , 38 ], investigation of healthy children [ 38 , 39 , 40 ], surveillance of EVs [ 41 ], and rotavirus surveillance [ 32 ]. After 2010, the proportion of EV-A steadily began to increase among both AFP and EVI isolates ( Figure 4 ).…”

More than 100 types of non-polio enteroviruses (NPEVs) are ubiquitous in the human population and cause a variety of symptoms ranging from very mild to meningitis and acute flaccid paralysis (AFP). Much of the information regarding diverse pathogenic properties of NPEVs comes from the surveillance of poliovirus, which also yields NPEV. The analysis of 265 NPEV isolations from 10,433 AFP cases over 24 years of surveillance and more than 2500 NPEV findings in patients without severe neurological lesions suggests that types EV-A71, E13, and E25 were significantly associated with AFP. EV-A71 was also significantly more common among AFP patients who had fever at the onset and residual paralysis compared to all AFP cases. In addition, a significant disparity was noticed between types that were common in humans (CV-A2, CVA9, EV-A71, E9, and E30) or in sewage (CVA7, E3, E7, E11, E12, and E19). Therefore, there is significant evidence of non-polio viruses being implicated in severe neurological lesions, but further multicenter studies using uniform methodology are needed for a definitive conclusion.

“…Diverse factors such as the differential seasonal fluctuations of types, immunity generation into population, occurrence of large outbreaks of different diseases, or the introduction of new viral variants, among many others, could act as driving forces of this pattern. Unfortunately, most of the environmental studies of EVs which used next-generation sequencing have been conducted during short sampling campaigns as in our case [26][27][28][45][46][47]. Long-term environmental surveillance projects could be useful to elucidate epidemiological patterns for EVs beyond the bounded subset of EVs commonly detected when clinical specimens obtained from AM or AFP cases are studied.…”

The knowledge about circulation of Human Enteroviruses (EVs) obtained through medical diagnosis in Argentina is scarce. Wastewater samples monthly collected in Córdoba, Argentina during 2011–2012, and then in 2017–2018 were retrospectively studied to assess the diversity of EVs in the community. Partial VP1 gene was amplified by PCR from wastewater concentrates, and amplicons were subject of next-generation sequencing and genetic analyses. There were 41 EVs detected, from which ~50% had not been previously reported in Argentina. Most of the characterized EVs (60%) were detected at both sampling periods, with similar values of intratype nucleotide diversity. Exceptions were enterovirus A71, coxsackievirus B4, echovirus 14, and echovirus 30, which diversified in 2017–2018. There was a predominance of types from EV-C in 2017–2018, evidencing a common circulation of these types throughout the year in the community. Interestingly, high genetic similarity was evidenced among environmental strains of echovirus 30 circulating in 2011–2012 and co-temporal isolates obtained from patients suffering aseptic meningitis in different locations of Argentina. This study provides an updated insight about EVs circulating in an important region of South America, and suggests a valuable role of wastewater-based epidemiology in predicting outbreaks before the onset of cases in the community.

“…In fact, some studies have demonstrated that the use of HEp-2c cells increased the number of EV C isolates, suggesting that the absence of this cell line in an isolation routine can lead to underestimating EV C isolation [ 20 , 21 , 22 ]. Conversely, the high detection rate of EV B species may be due to the use of RD cells for virus isolation, which are highly sensitive to EV B but less susceptible to EV A and non-polio EV C [ 21 , 22 , 23 ].…”

Environmental Monitoring for Enteroviruses in Maputo, Mozambique—2018

Due to the possibility of wild poliovirus importation from endemic regions and the high circulation of vaccine-derived poliovirus type 2 in the African region, Mozambique implemented a surveillance program to monitor the circulation of enteroviruses in the environment. From January to November 2018, a period that immediately preceded the cVDPV outbreak in Africa, 63 wastewater samples were collected from different areas in Maputo city. A total of 25 samples (39.7%) were positive based on cell culture isolation. Non-polio enteroviruses were found in 24 samples (24/25; 96%), whereas 1 Sabin-related poliovirus was isolated. Neither wild nor vaccine-derived poliovirus was detected. High circulation of EVB species was detected. Environmental surveillance in the One Health approach, if effectively applied as support to acute flaccid paralysis, can be a powerful aid to the public health system to monitor poliovirus besides non-polio enteroviruses in polio-free areas.
