Winter is the time of year when people feel very blessed. This isn't because people feel thankful for the cold weather, nor because the important festivals---Christmas or Spring Festival---offer an excuse to celebrate. In fact, “Bless you!” is a common response if someone sneezes, a symptom (症状）of catching a cold or the flu.
Colds and the flu are the most common illnesses of autumn and winter as the weather gets colder. Viruses cause them. If you get one you will feel annoyed, but it is not usually serious. The flu is spread from person to person when we come into contact with a person with the virus. We get the virus on our hands and then we touch our noses and our mouths. We can pass on the flu before we realize we have it. You can infect(传染) others one day before symptoms develop and for up to five days after becoming sick.
Getting a flu vaccination is the best way to prevent the illness. Even if your body has built up antibodies（抗体）for one kind of flu. The vaccine（疫苗）is only effective for one year and viruses are different from year to year, so it is necessary to get a flu vaccination every year. The best time to get the vaccination is October or November. Besides, there are other ways to reduce your chance of getting a flu. Wash your hands. Get enough rest. Eat garlic regularly. Don't let stress control you. Exercise regularly.
