Viruses can cause massive human mortality. The smallpox virus killed an estimated 10 to 15 million people per year until 1967. [3] Smallpox was finally eliminated in 1977 by extinction of the virus through vaccination, and the impact of viruses such as influenza, poliomyelitis and measles are mainly controlled by vaccination.

Aichivirus A formerly Aichi virus (AiV) [1] belongs to the genus Kobuvirus in the family Picornaviridae. [2] Six species are part of the genus Kobuvirus, Aichivirus A-F. [3] Within Aichivirus A, there are six different types including human Aichi virus, canine kobuvirus, murine kobuvirus, Kathmandu sewage kobuvirus, roller kobuvirus, and feline kobuvirus. [3]
Waterborne diseases were once wrongly explained by the miasma theory, the theory that bad air causes the spread of diseases. [ 27 ] [ 28 ] However, people started to find a correlation between water quality and waterborne diseases, which led to different water purification methods, such as sand filtering and chlorinating their drinking water.
In the last several weeks, wastewater surveillance at 59 of 190 U.S. municipal and regional sewage plants has revealed an out-of-season spike in influenza A flu viruses — a category that also ...
For monitoring influenza A virus in wastewater, CDC compares the most recent weeks of influenza A virus levels recorded at a wastewater site to levels reported between Oct. 1, 2023 and March 2 ...
But wastewater surveillance — the testing of sewage for signs of pathogens such as SARS-CoV-2, poliovirus and mpox virus — has yet to be employed in the tracking of H5N1 bird flu virus.
Human water-borne diseases usually come from other humans, thus human-derived materials (feces, medical waste, wash water, lawn chemicals, gasoline engines, garbage, etc.) should be kept far away from water sources. For example, human excreta should be buried well away (>60 meters/200 feet) from water sources to reduce contamination. [9]
From there, the CDC began monitoring wastewater for COVID-19 in 2020 (the first widespread sewage monitoring program in the U.S., Kirby says), and ramped up the program in 2022.
