CareXpress Urgent Care lays down why Winter is flu season.
We all know about flu season, but why is flu season…flu season? Is it something about the winter air that makes the flu virus more contagious? Is it because we spend more time indoors and close to other people? Or is it a combination of lots of factors? CareXpress Urgent Care has some answers.
Well, the fact that people stay inside and in close proximity to other humans certainly doesn’t help contain the virus. But the virus can only spread in a home if someone is already infected, so why does the virus seem to spring up in the colder months and not say, in may when more people will be outside where they could be exposed to the virus? It turns out, according to a study, it may be the cold weather itself that’s responsible for the virus’s winter spike.
Studies have shown that the flu virus seems to translate better when the air is cold and humid. Like most of winter! Studies done on guinea pigs showed that when the air was warmer, around 86 degrees, the virus hardly transferred at all. And when the humidity was cranked up, the same result. The virus didn’t seem to be able to transfer between hosts when the air was too hot or humid. Researchers think it’s because the flu travels through the air on particles exhaled from a sick host. In cold, dry air the particles can travel farther and stick around longer meaning it’s more likely to infect someone. The reason warmer, wetter air interferes, researchers think, is because moisture gathers around the particles making it too heavy to float in the air. This causes the particles the virus is riding on to fall to the floor where they can’t infect anyone.
