The flu is caused by influenza viruses that infect the nose, throat, and lungs. These viruses spread when people with flu cough, sneeze or talk, sending droplets with the virus into the air and potentially into the mouths or noses of people who are nearby.

people can misdiagnose themselves because they don’t always know that sicknesses can have the symptoms as others and they assume it’s the flu because it’s a known sickness.  

The flu, also known as the influenza virus, is diagnosed year-round in the United States. Fall and winter seasons are when the greatest impact is usually seen and, therefore, is considered the "flu season." Influenza activity has a period of greatest activity between December and February, but the activity can last until May.

The flu is a very dangerous disease that is thankfully not anymore in circulation. When people working in government jobs are affected by this disease it delays the time they come to work and therefore the country's business goes down.

Also a large amount of money is spent by the government to cure this disease and the government has to focus on the eradication of these diseases and waste time.

When infected people use some resources and many citizens use the same resource then a large number of people could get affected due to this and therefore the country's economy is reduced with the resources.
