Spillover: Animal Infections and the Next Human Pandemic is 2012 non-fiction book by David Quammen.The book, written in narrative form, tells through the personal experiences of the author, who interviewed numerous pathologists and virologists globally to trace the evolution of some of the major pathogens that have affected the human species following a species leap (), a natural process by ...
Virus latency (or viral latency) is the ability of a pathogenic virus to lie dormant within a cell, denoted as the lysogenic part of the viral life cycle. [1] A latent viral infection is a type of persistent viral infection which is distinguished from a chronic viral infection. Latency is the phase in certain viruses' life cycles in which ...
When the virus replicates faster than the immune system can control, it can destroy cells and harm the body, and it can even incite an over-zealous immune reaction that can cause other damage.
While the mechanism of disease-carrying is still unknown, researchers have made progress towards understanding how certain pathogens can remain dormant in a human for a period of time. [4] A better understanding of asymptomatic disease carriers is crucial to the fields of medicine and public health as they work towards mitigating the spread of ...
She also said that if non-immunocompromised people feel well by day 11 but still test positive on an antigen test, “it is exceedingly unlikely” they’re still infectious.
Deaths from a handful of viruses that spill over from animals to humans are set to increase 12-fold by 2050 due to climate change and habitat encroachment, according to a new study published in ...
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [2] [3] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity.
Some viruses can "hide" within a cell, which may mean that they evade the host cell defenses or immune system and may increase the long-term "success" of the virus. This hiding is deemed latency. During this time, the virus does not produce any progeny, it remains inactive until external stimuli—such as light or stress—prompts it to activate.
