There are many illnesses that are not up to us, yet there are some that are completely at our control. For example, communicable diseases which are caused by germs transmitted through people, animals, surfaces, foods and air, can often times be prevented. It is highly recommended to take the flu shot every year, especially for people who are at high risk for flu complications. This is important because it helps prevent the spread of the flu, which can cause a worsening of chronic medical conditions.
