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.
Incubation Period. The incubation period, or time from clinical exposure to the onset of clinical signs, is approximately 2 to 4 days for CIV. This is a relatively short incubation period that is similar to that of influenza infection in other species.However, it is shorter compared to other causes of acute respiratory disease in canines, such as canine distemper and Bordetella bronchiseptica.he incubation period, or time from clinical exposure to the onset of clinical signs, is approximately 2 to 4 days for CIV.
