Wastewater-based epidemiology (WBE) has been employed for monitoring the presence of SARS-CoV-2 infected population. Herein, study aims to apply WBE surveillance and in Bangkok, where highest official covid-19 cases reported Thailand, during fully opening international tourists early 2023. A total 200 wastewater samples (100 influent 100 effluent samples) were collected from 10 treatment plants (WWTPs) January–May RNA was detected by real time qRT-PCR with accounting 51% (102/200). Of these, 88% (88/100) 14% (14/100) samples, respectively. The concentration ranged 4.76 × 102–1.48 105 copies/L. amount increased approximately 4 times lag phase (January–March) log (April–May). Spearman's correlation coefficient revealed that between estimated population weekly statistically significant (p-value = 0.017). had a relationship (r 0.481, p-value < 0.001). Lag analysis warning 1–3 weeks before rising observed. GIS applied spatial-temporal at province level, suggesting dashboard should be further developed.

Abstract Purpose of Review This study aims to review recent literature reporting wastewater-based surveillance (WBS) the monkeypox virus (MPXV) with a major focus on sample collection, processing, and public health safety issues. Recent Findings Various studies revealed presence MPXV genetic markers in sewage, wastewater treatment plants, drainage systems hospitals multiple countries. Summary Mpox (formally monkeypox) has been identified more than hundred countries, confirming at least 93,937 cases from 06 May 2022 03 February 2024. The MPXV, causative agent for mpox, is zoonotic having genome DNA. Major symptoms disease are rash, fever, headache, chills lymph pain. It about 10% case fatality rate, without any approved vaccine, but researchers investigating development therapeutic vaccines. DNA signature long reported urine, stool, saliva, semen, spit samples clinical patients, make feasible tracking wastewater. Furthermore, have environmental samples. As possible hosts (e.g., small mammals rodents), their detection might indicate circulation including non-human hosts. persistence infective particles ambient environment not fully investigated. Also, risks transmission through contaminated milieu unknown. WBS can be an effective tool identifying hotspots trends communities. Graphical

Wastewater-based epidemiology offers a time- and cost-effective way to monitor SARS-CoV-2 spread in communities therefore represents complement clinical testing. WBE applicability has been demonstrated number of cases over short-term periods as method for tracking the prevalence an early-warning tool predicting outbreaks population. This study reports viral loads from wastewater treatment plants (WWTPs) hospitals 6-month period (June December 2020). Results show that overall range load positive tested samples was between 1.2 × 10

Tuberculosis (TB) remains a persistent challenge to public health and presents substantial menace, especially in developing nations of sub-Saharan Africa. It exerts considerable strain on healthcare systems these regions. Effective control requires reliable surveillance, which can be improved by incorporating environmental data alongside clinical data. Molecular advances have led the development alternative surveillance methods, such as wastewater-based epidemiology. This studyinvestigated presence, concentration, diversity Mycobacterium tuberculosis complex, cause TB, from six African countries: Ghana, Nigeria, Kenya, Uganda, Cameroon, South Samples were collected wastewater treatment plants. All samples found contain species that been linked TB both humans animals, including tuberculosis, bovis, africanum, caprae, at varying concentrations. The highest median concentration was reaching up 4.7 Log copies/ml for MTBC, 4.6 M. 3.4 africanum. presence africanum outside West Africa Africa, Uganda could indicate spread pathogen. study underscores usefulness epidemiology tracking shows even treated may pathogens, posing potential risks.
