During this period (usually days to weeks post-exposure) fifty to ninety percent of infected individuals develop an influenza or mononucleosis-like illness called acute HIV infection (or HIV prodrome), [2] [3] the most common symptoms of which may include fever, lymphadenopathy, pharyngitis, rash, myalgia, malaise, mouth and esophageal sores ...
In epidemiology, particularly in the discussion of infectious disease dynamics (modeling), the latent period (also known as the latency period or the pre-infectious period) is the time interval between when an individual or host is infected by a pathogen and when that individual becomes infectious, i.e. capable of transmitting pathogens to ...
The prodrome is a period during which an individual experiences some symptoms and/or a change in functioning, which can signal the impending onset of a mental health disorder. [5] It is otherwise known as the prodromal phase when referring to the subsyndromal stage or the early abnormalities in behavior, mood, and/or cognition before illness ...
The relationship between the latent period, the infectious period (the period of communicability) and the incubation period. In some diseases, as depicted in this diagram, the latent period is shorter than the incubation period. A person can transmit an infection without showing any signs of the disease.
After the latency period (but before clinical infection) the infected person can transmit the disease without signs of any symptoms. Such infection is called subclinical infection. Incubation period (also known as the latent period or latency period ) is the time elapsed between exposure to a pathogenic organism, a chemical, or radiation , and ...
Prodromal: the first signs or symptoms appear, which indicates the clinical start of the disease. [ 7 ] [ 8 ] Clinical : specific signs and symptoms appear, which allows the doctor to not only identify the disease but also determine the appropriate treatment in hopes of curing the patient or at least preventing long-term damages.
A differential diagnosis of acute infectious mononucleosis needs to take into consideration acute cytomegalovirus infection and Toxoplasma gondii infections. Because their management is much the same, it is not always helpful–or possible–to distinguish between Epstein–Barr-virus mononucleosis and cytomegalovirus infection.
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. [1] An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection.
