An example of an inference that certainly does commit the fallacy of division is this: (1) Water is liquid. Therefore: (2) H2O molecules are liquid. This argument, in attributing a macro-property of water, liquidity, to its constituent parts, commits the fallacy of division.
Flu Incubation Period. The typical flu incubation periodâthe time between exposure and the start of symptomsâis between 24 hours and four days, with the average being two days. This means that if you are exposed to the influenza virus and become infected, you will start to experience flu symptoms anywhere between 24 hours and four days after the exposure.
Flu has a short incubation period; the gap between exposure to the virus and development of symptoms is two to three days. You become infectious about a day before you begin to feel unwell, and the symptoms last three to seven days.
