[7] Sewage contaminated water contains many viruses, over one hundred species are reported and can lead to diseases that affect human beings. For example, hepatitis, gastroenteritis, meningitis, fever, rash, and conjunctivitis can all be spread through contaminated water. More viruses are being discovered in water because of new detection and ...
Many latent and asymptomatic viruses are present in the human body all the time. Viruses infect all life forms; therefore the bacterial, plant, and animal cells and material in the gut also carry viruses. [6] When viruses cause harm by infecting the cells in the body, a symptomatic disease may develop.
This category includes any viruses that can infect humans. Pages in this category should be moved to subcategories where applicable. This category may require frequent maintenance to avoid becoming too large.
Fungi have a rigid cell wall made of chitin, so most viruses can get inside these cells only after trauma to the cell wall. [46] See, Nerva L, Ciuffo M, Vallino M, Margaria P, Varese G, Gnavi G, Turina M (2016). "Multiple approaches for the detection and characterization of viral and plasmid symbionts from a collection of marine fungi". Virus ...
Human and monkey cells are used in both traditional viral culture and shell vial culture. Human virus types that can be identified by viral culture include adenovirus, cytomegalovirus, enteroviruses, herpes simplex virus, influenza virus, parainfluenza virus, rhinovirus, respiratory syncytial virus, varicella zoster virus, measles and mumps.

Polyomaviridae is a family of viruses whose natural hosts are primarily mammals and birds. [1] [2] As of 2024, there are eight recognized genera. [3]Fourteen species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.

The virus is unable to infect humans in the way it does insects, because human stomachs are acid-based and NPV requires an alkaline digestive system in order to replicate. It is possible for the virus crystals to enter human cells, but not to replicate to the point of causing illness. [8]
