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 ...
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.

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 ...
The wastewater tests are capable of detecting many types of influenza A, including the H5N1 subtype, but the findings do not indicate the source of the virus or whether it came from a bird, cow ...
Wastewater-based epidemiology has been used to estimate illicit drug use in communities or populations, but can be used to measure the consumption of alcohol, caffeine, various pharmaceuticals and other compounds. [2] Wastewater-based epidemiology has also been adapted to measure the load of pathogens such as SARS-CoV-2 in a community. [3]
Both agriculture and sewage treatment produce inputs into rivers with very high concentrations of bacteria and viruses including a wide range of pathogenic organisms. Even in areas with little human activity significant levels of bacteria and viruses can be detected originating from fish and aquatic mammals and from animals grazing near rivers ...
There are two common human influenza A viruses: H1N1 and H3N2. The "H" stands for hemagglutinin, which is an identifiable protein in the virus. The "N" stands for neuraminidase.
Waterborne diseases are conditions (meaning adverse effects on human health, such as death, disability, illness or disorders) [1]: 47 caused by pathogenic micro-organisms that are transmitted by water. These diseases can be spread while bathing, washing, drinking water, or by eating food exposed to contaminated water. [2]
