Many Health News outlets have discussed the flu this year as being the worst strain since 2003/2004. The southeast currenlty has the highest concentration of flu cases. You may not want to invest in some onions (the story about onions absorbing viruses and bacteria out of the air is false and holds no scientific merit) simply get some extra rest and fluids. L-Glutamine every day will also help boost the immune system. Also Vitamin C will not help you get better once you are sick. Rest rest rest and wash your hands.
