TERRE HAUTE, Ind. (WTHIT) - Experts are keeping a close eye on this season's widepsread flu outbreak.
They say one factor contributing to the outbreak may be this winter's weather. Many know the winter months as flu season but why does the flu virus spread during the winter?
Experts say the low humidity in the air, not just the cold, allows the virus to spread faster. Last December was drier than normal in many states. Health officials say people's immune systems are already weaker in the winter and the virus being able to spread easier has created a dangerous situation.
If you remember December had a long stretch of bitter cold dry conditions countrywide. Local healthcare officials say this may be one of many reasons the flu is so severe this season.
"During that time that cold period, it might have increased a little bit more based on what we know from the virus that it likes the real cold weather it likes the dry humidity, that might have icnreased the chances of it being a little more prevelant in our community" Dr. Andre Anderson with Union Hospital says.
Dr. Anderson says the fluctuating weather from hot to cold inside a week many times this season can weaken immune systems even further during the winter. He says always make sure you are disinfecting objects inside to avoid spreading the virus further.
