In the United States, shoes are sized for length and width. Nine widths are available, ranging from AAA (narrowest) to EEE (widest). For men, a D width is considered a medium; for women, a medium is a B width. For comfortable shoe-wearing, it is important to get your width right.
The incubation period for HPV ranges from 1 to 6 months; however, latency periods of up to 3 years or more are suspected. The lesions are present for several months and usually regress spontaneously within two years, although some may persist indefinitely.
An incubation period is the amount of time it takes between exposure to a virus, and the development of symptoms caused by the virus. For the H1N1 flu virus, the incubation period is between 1 and 7 days, with 4 days being the most common.
