Preventing the flu may not come down to hand sanitizers and risky vaccinations. A new study has found that only half of all individuals affected with the flu virus actually get sick, highlighting the necessity of a powerful immune system that is able to respond to the flu virus appropriately.
The study comes from the University of Michigan, where researchers infected 17 healthy individuals with the flu, about half of which reported actually getting sick as a result. The other half felt completely fine.
The average American touches around 300 different surfaces every 30 minutes, demonstrating that it is virtually impossible to avoid coming in contact with a virus that may invade your body. Instead, a boosted immune system will be able to defend against potentially-harmful viruses that seek to make you ill. You cannot prevent coming in contact with bacteria and viruses, but you can certainly establish a biological defense against them.
