Assessment of SARS-CoV-2 Stability in human and environmental matrices, and potential hazards.

In the context of the ongoing pandemic of COVID-19, SARS-CoV-2 was detected in human excreta and environmental matrices. The occurrence of SARS-CoV-2 in environmental compartments raises questions on its fate and stability in these matrices and its potential to spread in the exposed communities. This review focused on the stability of the SARS-CoV-2 in human excreta, wastewater, soils, crops, and other environmental matrices, that may be reached through human excreta and sewage products spreading.

Occurrence of SARS-CoV-2 in excreta, sewage, and environment: epidemiological significance and potential risks.

The detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients' excreta raises the issue of its occurrence and fate in sewage. This review has focused on the presence of the SARS-CoV-2 in human excreta, wastewater, sewage sludge, and river waters. It explored the potential use of the wastewater-based epidemiology approach to report on the situation of current and eventual future SARS-CoV-2 outbreaks.

Pathogenic parasites in sewage irrigated crops and soil: pattern of occurrence and health implications.

The current study aimed to determine the contamination level by human parasite eggs and cysts of sewage-irrigated soil, food crops and fodder crops. Field trials were conducted on spray-irrigated lettuce and flood-irrigated crops using raw wastewater and fresh water. Findings showed that irrigation by raw wastewater led to crops contamination with parasite eggs and cysts in varying levels.

Respiratory cryptosporidiosis in two patients with HIV infection in a tertiary care hospital in Morocco.

Respiratory cryptosporidiosis is recognized as a late-stage complication in persons with AIDS. We report two cases of respiratory cryptosporidiosis in patients with HIV infection. The first patient was a 46-year-old person with chronic diarrhea, a two-month history of low-grade fever, progressive dyspnea and productive cough.

The effect of waste water reuse in irrigation on the contamination level of food crops by Giardia cysts and Ascaris eggs.

In Marrakech, raw sewage has been used for farming purposes for several decades for many types of crops. This study aimed to determine the contamination level of Giardia cysts and Ascaris eggs for crops designated for human consumption. Collected crops in irrigated fields were turnip, marrow, squash, potatoes, pepper and eggplant.
