There are two types of flu: seasonal flu and pandemic flu. Seasonal flu occurs every year, typically between October and May in the United States. Pandemic flu is a global outbreak of a new flu virus. Seasonal flu is more common, but pandemic flu can be more severe.
Seasonal flu is caused by viruses that mainly infect the nose, throat, and lungs. These viruses are spread mainly by droplets made when people with flu cough, sneeze, or talk. People with seasonal flu can spread it to others up to about 6 feet away. Seasonal flu viruses can also live on surfaces, like doorknobs and tables, for a short time. A person can get seasonal flu by touching these surfaces and then touching their mouth or nose.
Pandemic flu is caused by a new flu virus that has spread around the world. Pandemic flu can be more severe than seasonal flu. It can cause a worldwide outbreak of disease. Pandemic flu viruses are spread in the same way as seasonal flu viruses.
Types of Flu
There are two types of flu, Type A and Type B. Both types are contagious and can cause serious illness, but they are different in a few ways.
Type A flu is more common and tends to cause more severe illness, especially in young children and the elderly. It is also more likely to cause pandemics, which are widespread global outbreaks.
Type B flu is less common and usually causes milder illness. It does not cause pandemics.
Both types of flu are caused by viruses that infect the respiratory system, and both types are spread through contact with respiratory secretions, such as saliva, mucus, or blood. They can also be spread through contact with contaminated surfaces, such as doorknobs, door handles, or countertops.
Causes of Flu
The difference between cold and flu is that the flu is a contagious respiratory illness whereas a cold is a milder respiratory illness than the flu. Flu can cause mild to severe illness, and sometimes can lead to death. The best way to prevent the flu is by getting a flu vaccine each year.
Symptoms of Flu
Flu, or influenza, is a contagious respiratory illness caused by viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent flu is by getting a flu vaccine each year.
The four main symptoms of the flu are:
3. Sore throat
4. Runny or stuffy nose
These symptoms usually start suddenly and can include other symptoms such as:
1. Body aches
If you have these symptoms, it’s important to see a doctor right away, as the flu can lead to serious complications, such as pneumonia, bronchitis, and sinus infections. Treatment with antiviral drugs can help people who are very sick with the flu or who are at high risk for serious flu complications.
Treatment of Flu
There are several ways to treat the flu. The most important thing is to get plenty of rest and drink lots of fluids. You can also take over-the-counter medication such as ibuprofen or acetaminophen to relieve fever and pain. If you have a severe case of the flu, you may need to be hospitalized and treated with antiviral drugs.
There are two types of flu, Type A and Type B. Both types are contagious and can cause severe illness. Type A flu is more severe and can cause more serious complications, such as pneumonia. Type B flu is less severe and typically causes milder symptoms.
