non persistent infection without symptomatic relapses and remission
a latent infection
There are several types of microbes that could cause infection and they may be acute chronic or latent infections. A microbe that could cause an acute infection is rhinovirus, one that could cause a chronic infection is hepatitis C and one that could cause a latent infection is herpes zoster.
An inapparent infection occurs when a susceptible person is exposed to an agent, is consequently infected, but neverdevelops clinical symptoms (subclinical). An inapparent infection may result in immunity - but they may not develop immunity and could even become a carrier.In contrast, an exposed susceptible person may develop symptoms (clinical infection), but later enter a period where they no longer exhibit those symptoms. This person would be said to have a "latent infection". They have not recovered - they are still infected -- and they might start to exhibit clinical symptoms later.Exposed ---- Infected ------ no symptoms --------------------------------------> Resolution INAPPARENT INFECTIONExposed ---- Infected ----- symptoms ----no symptoms ---- symptoms ----> Resolution|< Latent Infection>|- Dominick A.

an example of a latent virus is a host cell
No, the latent stage of an infection is when the pathogen isn't causing symptoms or damage. The pathogenic stage is when the pathogen is causing symptoms or damage.
About 30% of the worlds' population carries TB.
Herpes simplex virus is an example of a latent viral infection. After initial infection, the virus can remain dormant in nerve cells for long periods of time before reactivating, causing recurrent outbreaks of symptoms.
Acute infections have a rapid onset and tend to resolve quickly, while chronic infections last for a longer period of time and may persist for months or years. Latent infections involve a period where the virus or bacteria is in a dormant state within the host, potentially reactivating later to cause symptoms.
AIDS or HIV is a latent disease. It can show up years after contracting the disease.
Chronic latent state refers to a persistent but inactive phase of a disease or condition where symptoms are not present but the causative agent (such as a virus or bacteria) remains in the body. This phase can last for an extended period without causing any symptoms or signs of active infection.
latent
A latent virus remains dormant in the host cell without causing symptoms, but can reactivate later to cause disease. An active virus continuously replicates and causes symptoms, leading to an active infection. Both types of viruses can cause disease, but latent viruses have periods of inactivity while active viruses are constantly causing symptoms.
