The incubation period following exposure to the hepatitis E virus ranges from 2 to 10 weeks, with an average of 5â6 weeks. The infected persons are believed to excrete the virus beginning a few days before to around 3-4 weeks after the onset of disease.
For people paid every two weeks, there are 26 pay periods in a year. Two weeks makes 10 business days, for a total of 260 working days, not accounting for vacation time that you take. In the US people commonly say there are 260 weekdays/work days in a year or 2080 work hours in a year based on 52 weeks per year. (260 = 5wkdys/wk*52wks) (2080=40hrs/wk*52wks/yr) The number can vary by year. For example, 2012 had 261 weekdays and 366 total days.
There is 365 in a year (or 366 every 4 years). How many weeks in a year? There are 7 days a week, and 365 days a year, we find out the scale by. 365 days/year x 1 week / 7 days. Then we will figure out that there is 365/7 weeks/year (quite bad) There is 12 month per year as well. Similarly, we can calculate how many week AVERAGE per month by 1 year/12 month x 365/7 weeks/ 1 year After multiplication, we get 365/84 weeks/month average. It's about 4.3 weeks per-month average. It is not so surprising, the smallest month of the year is 28 days ( or 29 days), which is exactly 4 weeks (and a day).
