Teacher: Now, understand the problem? Solve this instance: The typical flu incubation period is 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. Another factor that contributes to how the flu spreads is when exactly you may be contagious. You may also wonder how long it takes to get sick after you have been exposed and how long you are contagious when you have it. Flu Incubation Period. The typical flu incubation periodthe time between exposure and the start of symptomsis 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. You may also wonder how long it takes to get sick after you have been exposed and how long you are contagious when you have it. Flu Incubation Period The typical flu incubation periodthe time between exposure and the start of symptomsis 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. Viral Shedding. Influenza spreads mainly by respiratory droplets that contain copies of the virus that have replicated in your body. Viral shedding, which correlates with infectivity, occurs starting approximately 1 day before symptoms appear and can continue for up to 10 days after symptoms develop. The most active period of contagion falls between 1 and 4 days after the start of symptoms, according to a May 2010 article published in the Journal of Infectious Disease. The study also found that in a small number of cases, infection transmission occurred before symptoms appeared. If you are exposed to someone with the flu, avoid close contact with the person, and wash your hands frequently. 1 Vitamin C: Although Vitamin C is widely used and has many benefits, there is no scientific proof that it will help you avoid an illness such as the flu or a cold. Tamiflu Actions. Tamiflu acts by reducing the number of cells in your body that are affected by the influenza virus. It does this by binding to a coating, called neuraminidase, that's found on the surface of the virus. Neuraminidase allows the virus to penetrate healthy cells, where it can then produce more copies of the virus. After symptoms start, adults can spread the virus for five to 10 days. However, the amount of virus spread decreases significantly after three to five days. Adults are most contagious with the flu from 24 hours before symptoms start to three to five days afterward. Flu symptoms generally don't come on gradually. 1 More often, people describe the onset of flu as if they were hit by a truck.. You feel fine, and then suddenly, an hour later, you feel like you can hardly move. 2 We know that it is highly contagious and can be spread before you even have symptoms. Preventing the Flu After Exposure. 1 Vitamin C: Although Vitamin C is widely used and has many benefits, there is no scientific proof that it will help you avoid an illness such as the flu or a cold. 2 Humidifiers: Evidence suggests that viruses such as the cold and flu spread more easily in cold, dry air.
