and described by the formula: where A is the amplitude of oscillation, f is the frequency, t is the elapsed time, and is the phase of the oscillation. The phase determines or is determined by the initial displacement at time t = 0. A motion with frequency f has period. Two potential ambiguities can be noted:
Incubation Period Shingles is not transmitted from exposure to another infected person so there is no applicable incubation period. Anyone who has recovered from varicella may develop shingles. Mode of Transmission Transmission of the virus occurs through direct contact with the rash or fluid from the lesions.
The incubation period is from 14 to 16 days from exposure, with a range of ten to 21 days. The incubation period may be prolonged in immunocompromised patients and those who have received varicella zoster immune globulin (VZIG).he incubation period is from 14 to 16 days from exposure, with a range of ten to 21 days.
