Transcript for CDC reports flu cases on rise as a second wave appears to hit
Meanwhile, fears about the coronavirus have been overshadowing the flu which, in fact, kills many more people and is on the rise here in the U.S. As what appears to be a second wave of the flu spreads. Parents are now being warned that this flu season has been worse for children than any season in a decade and ABC's Diane Macedo is right here with more. Diane, good morning to you. Reporter: Dan, good morning to you. So we already have 92 flu-related child deaths reported which is higher at this point in the year than in any season in the past decade. Experts say one reason for that is that the two strains going around are both especially hard on kids, something they call a double barrel flu season. This morning, a second wave of the flu virus is hitting the U.S. New numbers from the CDC show after falling for the first two weeks of the year flu cases are back on the rise. So far this season the CDC estimates there have been at least 26 million flu cases, 250,000 hospitalizations and 14,000 deaths. And the season has been especially hard on children with flu-related child deaths and hospitalizations at their highest point in a decade. What we found is that there's been more of a higher predominance of influenza B and unfortunately influenza B tends to affect the pediatric population a bit harder. Reporter: For 16-year-old Katie giovanniello it turned deadly. It's so sad she's not here. It's so sad. Reporter: Her mother says the teen was diagnosed with the flu virus February 2nd and died just five days later even though she had a flu shot. That these symptoms could kill her. I just didn't know that. I really didn't and I didn't really, really know the flu can kill you. Reporter: The CDC is releasing flu vaccine effectiveness stats next week. In the meantime, it is still the best way to protect yourself along with hand washing and frequently washing touched surfaces. Hearing from that mom. It's heartbreaking. Awful and wrenching.
