People die from flu every year. Flu can be bad at any time. I myself had a bad flu back in January, with fever, chills, and loss of appetite for a few days, and a cough that lingered for weeks. I'm just glad I got it in January and not in March. At the worst of the flu I just kept hoping I wouldn't develop pneumonia, because pneumonia is actually deadly. I would've been worried out of my mind if I had those symptoms in March or later.
