Why is there a flu season and not flu all year around?

Question

The flu virus seems to spread more commonly during only part of the year. Why?

Answer 1

Close quarters and kids back in school are two big reasons flu is more predominant in certain months. As the weather gets colder, we close doors and windows in our homes...keeps the flu/cold viruses locked into our homes. We also heat our homes drying the air and drying out our mucous membranes creating microscopic cracks in our airway where viruses jump in. Also, several holidays are in the winter months and everybody visits everybody...kissy-kissy, huggy-huggy...another area of close contact, not to mention shopping in crowded areas.

Answer 2

Because the most cases were recorded in certain months. When it is not those months, it is not flu season. The flu is mostly in winter, right. During the summer, most of the flu virus hides in something. During the winter, it finds organisms most venerable

Answer 3

Theoretically you can get flu year-round. But winter is the flu season because people stay indoors and they will transmitt diseases eaiser. And if people have winter allergies their resistance goes down against infectious diseases.

Answer 4

It spreads more during the colder winter months because more people tend to spend more time in close quarters with each other, making all diseases much more prevalent.

Answer 5

Yes, its the indoor close quarters thing. Further more as part of that, its when kids get back to school. Elementary, MS, HS, college; is all a breeding ground for viruses.

Answer 6

there is flu all year round but it is just more frequently caught at one particular time of the year
