There are few worse ways to die than with a bad case of pneumonia, gasping for every small breath of air, a burning pain in your chest, your panicked eyes bulging out of your head.

Unfortunately however, there may not be enough breathing machines for everyone.
Nobody seems to have prepared for a monster like this one...
