I'm a doctor for what's its worth.
Please everyone, relax. Certainly, there is concern particularly for the high risk elderly and those with complex medical issues but for the vast majority of people, this is really similar to a bad flu which is also high risk in elderly and patients with complicated medical issues (yet people still don't vaccinate for this......). Take the usual precautions by good handwashing/hygeine, avoid large crowds when possible, and look after your loved ones who are higher risk. The hysteria can be worse than the disease itself.
