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.
The incubation period is variable; it is probably three weeks to months for genital warts and several months to years for cervical cellular abnormalities, and decades for cervical cancer. The median duration of new cervical infections (measured by detection of HPV DNA) is 8 months but varies.
