In the absence of an effective drug or vaccine, we know that some infectious diseases similarly transmitted by the respiratory route have wreaked havoc: 20-40 million deaths from the influenza pandemic of 1918, the decimation of the population of Hawaii by the first introduction of measles and the lingering epidemic of tuberculosis that afflicts 8 million people annually now.

In the meantime, hospitals are trying to prevent the disease from taking root by isolating patients and using gowns, masks, goggles and gloves religiously - techniques that so far have proved extremely effective at preventing transmission...
