5 Fast Facts About the Flu

5 Fast Facts About the Flu
The flu is a contagious disease, and some of its common symptoms include fatigue, body aches, coughing, and fever. The flu season occurs every year. Although it’s late November, you can still get a flu shot if you haven’t done it already. Usually, the season strikes from October to May. Medical experts recommend getting the shot early, which means in October.

By doing so, you will be protected once the virus starts spreading. Some people can get the flu and recover within two weeks without complications. The illness is more dangerous for young children and people aged 65 and above. It can cause life-threatening complications. Therefore, you need to gather as much information as possible about the disease. Here are the five fast facts:

It Is Contagious Before Symptoms Become Visible

One of the top reasons why the flu is highly contagious is that one can pass the virus before becoming sick. According to the Center for Disease Control and Prevention, you can infect another person a day before you start noticing the symptoms. The risk of spreading the flu is high during the first three to four days of becoming sick.

The Symptoms Can Start Abruptly

The signs can happen rapidly. You may feel fine today but unable to do anything the following day as the symptoms worsen. In some cases, you can notice the symptoms a day after exposure. For others, this may take up to four days.

It May Take up to Two Weeks for the Flu Shot to Start Working

Getting the vaccine every year is one of the best ways to protect yourself against the illness. You need to go for it early in the season. Once you have gotten the flu shot, your body will start developing antibodies to fight the virus.

The Vaccine Doesn’t Cause the Flu

One of the common misconceptions about getting a flu shot is that it can cause respiratory illness. One of the varieties has a severely weakened form of the infection. However, it doesn’t cause the real flu. Instead, it enables the body to develop antibodies.

You Can Get the Flu Even after Getting a Shot

Note that the vaccine doesn’t offer 100% protection against the illness. You can get the flu if you are exposed to the virus before the shot starts working or if it is ineffective. A flu shot helps to reduce the risk of the disease by up to 60%.
