Mpox has a latent (incubation) period, a prodromal phase, and an eruptive phase. The latent period can last up to two weeks, during which individuals are not contagious and may not show any symptoms. The prodromal phase, marked by fever, headache, and swollen lymph nodes, follows the incubation period and precedes the rash. The eruptive phase, which involves the development of lesions, is characterized by a progressive rash that evolves through stages before healing.
Elaboration:
Incubation Period (Latent Phase):
This phase follows exposure to the mpox virus and can last from 5 to 21 days, averaging 6 to 13 days. During this time, individuals are not contagious and may not experience any symptoms.
Prodromal Phase:
This phase follows the incubation period and is characterized by initial symptoms like fever, headache, and swollen lymph nodes. These symptoms typically last for 1 to 4 days.
Eruptive Phase:
This phase is marked by the appearance of a rash that progresses through different stages:
Macules: Flat, discolored spots on the skin.
Papules: Raised, solid lesions.
Vesicles: Fluid-filled blisters.
Pustules: Pus-filled blisters.
Crusting: The lesions eventually form crusts and scabs before healing.
Scarring: In some cases, the healed lesions may leave behind scars.
Infectious Period:
Individuals are considered contagious from the onset of symptoms until all scabs have fallen off and the skin is healed.
