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, after initial infection, proliferation of virus particles ceases. However, the viral genome is not eradicated.
The time interval during which the host is infectious, i.e. the pathogens can be transmitted directly or indirectly from the infected host to another individual, is called the infectious period (or the period of communicability), defined as the period from the end of the pre-infectious period or the latent period until the time when the host ...
Such an infection is called a subclinical infection. In epidemiology , particularly in the discussion of infectious disease dynamics (mathematical modeling of disease spread), the infectious period is the time interval during which a host (individual or patient) is infectious, i.e. capable of directly or indirectly transmitting pathogenic ...
However, if they never tested negative, it is uncertain whether this might be a rebound or persistent infection from the original illness." It can be confusing, especially if you're trying to ...
There are some viruses that can maintain a persistent infection by infecting different cells of the body. Some viruses once acquired never leave the body. A typical example is the herpes virus, which tends to hide in nerves and become reactivated when specific circumstances arise. [25] Persistent infections cause millions of deaths globally ...
The "lifestyle" strategies of viruses in host cells. Acute infections tend to occur for a relatively short duration, while persistent infections are when the virus is not completely cleared from the body. In latent infections, reactivation of disease may occur a long time after the initial infection.
To enter the cells, proteins on the surface of the virus interact with proteins of the cell. Attachment, or adsorption, occurs between the viral particle and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where replication of the viral genome may commence.
How long the symptoms last depends on the severity of the case. With more mild cases (meaning that symptoms are similar to the common cold or flu), people tend to get better on their own after a ...
