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.
At Eddy's suggestion, the virus was dubbed polyoma, which means many tumors. The virus was named the Stewart-Eddy or SE polyoma virus, after their respective surnames. [1] The results of their collaboration earned them recognition by Time magazine in 1959, featuring a cover story on newly discovered viral agents that cause cancer. [1]
The virus is very common in the general population, infecting 70% to 90% of humans; most people acquire Human polyomavirus 2 in childhood or adolescence. [ 22 ] [ 23 ] [ 24 ] It is found in high concentrations in urban sewage worldwide, leading some researchers to suspect contaminated water as a typical route of infection.
The virus was also found in one of five grocery-shelf milk samples tested by federal researchers. Those samples showed the virus had been inactivated by pasteurization, reducing the health threat ...
Temperature has the highest effect on virus's survival in water since lower temperatures are the key to longer virus survival. For instance, an article published in 2018 noted that it takes one year for certain viruses including poliovirus and echovirus to decrease by a 5log unit at a temperature of 4 ° C, while it takes only a week to obtain ...
All known human polyomaviruses are fairly common in healthy adult populations and are usually asymptomatic. In studies that profile polyomavirus seroprevalence, or prevalence of detectable antibodies against viral proteins indicating either past or present exposure in immunocompetent adults, HPyV9 tends to have a relatively lower prevalence compared to other human polyomaviruses.
Sep. 13—The Maryland Department of Health has confirmed an individual living in the Eastern Shore region of the state tested positive for West Nile virus, marking the first confirmed human case ...
All known human polyomaviruses are fairly common in healthy adult populations and are usually asymptomatic. In studies that profile polyomavirus seroprevalence, or prevalence of detectable antibodies against viral proteins indicating either past or present exposure in immunocompetent adults, estimates of HPyV6 prevalence have ranged from approximately 60–85%, with evidence of low prevalence ...
