This year's flu season is severe. So far, at least 26 children in the United States have died of influenza, and thousands of elderly people have been hospitalized, according to the Centers for Disease Control and Prevention (CDC).
This year's flu season may be more severe compared with some recent years, and the current flu shot may not protect people as well against the disease, the Centers for Disease Control and Prevention said.
The long, harsh winter at the start of 2014 led some experts to predict that the cold season's "polar vortex" would turn into a "pollen vortex" during the warmer parts of the year, with a massive pollen eruption and a brutal allergy season.
The annual surge of sneezing, watery eyes and runny noses for allergy sufferers is only poised to get worse as the climate changes, and new research shows that greenhouse gases have a direct effect on aggravating these problems.
This time of year everyone's attention is on allergies — most importantly, how to stop them in their tracks. I have patients each spring who complain about symptoms while indoors — even though there is no pollen exposure inside.
