Every year there are millions of cases of people contracting the influenza virus which causes the flu. It is a condition that affects the respiratory tract, ie, the nose, throat and lungs. The incidence of flu cases rises significantly during the cold winter season around November and early January. Certain population groups are at higher risks to catching the flu virus, fro example, pediatrics and geriatric age groups and severely immunocompromised individuals (HIV/AIDS individuals). The best way to decrease the chance of getting the flu virus is to get a flu shot which is a vaccine. Studies have been shown to be 85% effective. The Center for Disease Control (CDC) recommends an annual flu shot especially for certain groups in the population.
