These articles always seem dubious, there is no corroborating evidence, not photoes of the victims, no background health information, absolutely nothing at all that would give a better picture of what actually happened. There is this pretentious insinuation that people who are otherwise perfectly healthy are instantly killed dead after a brief exposure to a particular germ, and I am calling Bullshit. Look deeper into these cases any you will almost always find that these people are in some way already compromised, and are so susceptible to illness that the common cold would have killed them just as easily as some phantom plague.
