The problem is that this has never been exposed to humans before so we don't have antibodies against it, have no real idea how it's spreading and it most definitely came from a lab otherwise animals like dogs and cats etc would also be exhibiting symptoms if it actually came from a sick animal. The flu is not a biological weapon and we have antibodies against it. The very old or very young or people with comprised immune systems are the ones fatally affected by it. This is nothing to freak out about but be well aware and knowledgeable about.
