"When you think about the flu, the seasonal flu, the flu that we're accustomed to, it typically tends to have the worse ramifications in people that don't have developed immune systems -- the elderly and the very young. They can't fight it off," said Dr. Sanjay Gupta, CNN's chief medical correspondent.

As their body starts to respond, to try and fight off that virus, they produce tons of inflammatory cells. Those inflammatory cells can sort of flood the lungs.
