We read a lot in the news about the new Wuhan coronavirus and the illness it causes (COVID-19), but some important points often get left out.
 COVID-19 is incredibly contagious.
COVID-19 transmits extremely easily from person to person. Interpersonal contact doesn’t need to be very long; a taxi driver can get the virus from a passenger, for example. The virus may be transmissible even before an infected person develops symptoms. It may also be transmissible for a few days after a person seems to be over the virus; it is possible to get positive virus tests, even after symptoms disappear. Some people may have the disease, but never show symptoms.
 The virus likely remains active on inanimate surfaces such as paper, plastic, or metal for many days.
There haven’t been tests on the COVID-19 virus per se, but studies on similar viruses suggest that human pathogens may remain infectious for up to eight days. Some viruses that only infect animals can survive for more than 28 days. China is reported to be destroying paper currency from the hardest hit area, because people do not want to accept money which may have viruses on it. Clearly, surfaces in airplanes, trains and buses may also harbor viruses, long after a passenger with the virus has left, unless they have been thoroughly wiped down with disinfectant.

Recently, a new coronavirus has been causing many illnesses and deaths. The virus first became active in Wuhan, China, but it has already spread to the rest of China. Scattered cases have been identified around the rest of the world as well.
There are two important questions that are already being encountered:
- How much of an attempt should be made to limit the spread of the new virus? For example, should businesses close to prevent the spread of the virus?
- Should this disease be publicized as being far worse than flu viruses that circulate each year and cause many deaths among the elderly and people in poor health? The median age of those dying from the new coronavirus seems to be about 75.
Unfortunately, there aren’t easy answers. We can easily see the likely outcome of under reaction. More people might die of the disease. More people might find themselves out of work for a couple of weeks or more with the illness. We tend to be especially concerned about ourselves and our own relatives.
The thing that is harder to see is that reacting too vigorously can have a hugely detrimental impact on the world economy. The world economy depends on international trade and tourism. China plays a key role in the world economy. Quarantines of whole regions that last for weeks and months can have a very detrimental impact on the wages of people in the area and profits of local companies. Problems with debt can be expected to spike. The greater the reaction to the coronavirus, the more likely the world economy will be pushed toward recession and job loss.
The following are a few of my thoughts regarding possible overreaction: Continue reading
