What is the difference between latent infection and inapparent infection?
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.
