In the dry season of autumn and winter, our respiratory tract is sensitive then respiratory diseases will enter. During the time what we want to prevent is the flu. Flu is a super-contagious virus that can make you feel miserable. Doctors call it influenza. Its symptoms are usually more serious than the sneezes and stuffy nose that you tend to get from a common cold.
You can understand it as a very serious cold. You may have a high fever, headache and muscle aches, cough, sore throat, and tiredness. You also might have a runny or stuffy nose, chills, headache, and nausea or vomiting. Most symptoms get better after about 5 days. But sometimes they can last for a week or more. Even if your fever and aches are gone, you can still feel drained for a few weeks.
Influenza is highly infectious. You can catch it when someone who has it sneezes or coughs, sending virus-filled droplets into the air that you breathe in. You can also get it if you touch somewhere that the virus landed and then touch your mouth, nose, or eyes. Flu is more common in winter because people spend more time indoors and in close contact with each other, so the virus spreads more easily.
So what should we do when the flu swept among the people near me?
- Get lots of rest.
- Drink plenty of clear fluids -- water, broth, and sports drinks -- so you don't get dehydrated, too.
- You can also try a humidifier or saline spray to help with a stuffy nose.
