Kids don't get sick in the fall because their immune systems are weakened, says specialist

In the weeks following the start of kindergarten and the school year, the number of respiratory infections among children increases significantly. Although many people suspect that this is due to a weakened immune system, the main factors are the return to group settings, indoor environments, changes in daily routines, and the easier and faster spread of viruses. However, adequate sleep, hand hygiene, regular ventilation, and vaccinations can go a long way toward prevention.
