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. [4]
Metagenomics can be used to study viruses effects on a given ecosystem and how they effect the microbiome as well as monitoring viruses in an ecosystem for possible spillover into human populations. [1] Within the ecosystems, viruses can be studied to determine how they compete with each other as well as viral effects on functions of the host.
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 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]
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]
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 ...
Opinions differ on whether viruses are a form of life or organic structures that interact with living organisms. [11] They are considered by some to be a life form, because they carry genetic material, reproduce by creating multiple copies of themselves through self-assembly, and evolve through natural selection .
