Colds: Hence its name, the common cold tends to be the most common illness seen throughout the school year. It’s often caused by one of many possible viruses, which means antibiotics are not necessary. Symptoms are most often mild with cough, congestion and runny nose. Occasionally, children will get a sore throat and/or fever with the common cold.

Strep throat: Often causing a sore throat, along with fever, headache and stomachache, this illness is caused by a bacterial infection. It is easily spread from child to child, especially if sharing drinks and eating utensils. Antibiotics are recommended to prevent complications from the infection.

Flu: Unfortunately, as schools get into full swing, so does the flu. It typically causes high fevers and body aches, along with cough, congestion and runny nose. Kids generally need to stay home from school for a few days until the fever subsides and they get their energy back.

Stomach flu: What is often referred to as the stomach flu, gastroenteritis causes vomiting and diarrhea. This is most commonly caused by a virus affecting the stomach and intestines. It is very common and very contagious. Staying hydrated is key during the stomach flu.

Pink eye: Pink eye (or conjunctivitis) causes red eyes with green or yellow drainage. Eyes might be sealed shut in the morning from crusting of the discharge. If this happens, gently soften and wipe away the discharge with a warm, wet washcloth. Pink eye is highly contagious and can be caused by either a virus or bacteria. Sometimes antibiotic eye drops are necessary to clear the infection.
