 How The Virus Spreads Among People

According to the Centers for Disease Control, in parts of China and other countries the virus is now spreading person-to-person. The CDC says the most common ways the virus spreads from an infected person to healthy people around them is when they cough or sneeze and release viral particles into the air and through touching, shaking hands and others forms of close personal contact. When healthy people touch objects or surfaces on which there are viral particles, then touch their eyes, nose or mouth before washing their hands, the virus can spread. In some rare cases fecal contamination can cause the virus to spread as well.

Potential For Becoming A Pandemic

There are three things this or any other virus must do to cause a pandemic in humans. They are:

Efficiently Infect Humans

Replicate In Humans

Spread Easily Among Humans

Currently it is unclear just how easy it is for the 2019-nCoV virus to spreads from one person to another. To determine this scientists must calculate the virus’ ‘basic reproduction number’. That’s the number of people on average who can catch the virus form one infected person. A recent New England Journal of Medicine article stated the estimated basic reproduction number for the 2019-nCoV virus is 2.2 people. That means each person that is infected has been spreading the 2019-nCoV virus to between 2 and 3 people. This means it has the potential to continue to spread unless public health measures stem the outbreak.

Low Risk For The American Public

According to the Centers for Disease Control, while the outbreaks of new viruses can always cause serious concern, the immediate risk of the 2019-nCoV outbreak to the American public is very low. The CDC points to the small number of people in the U.S. who are infected with the disease and the viruses limited spread in the U.S. as the primary reasons why. However, the CDC points out that the risk of an individual becoming infected “depends on exposure.” Health care workers and people who have relatives and close friends who are infected with 2019-nCoV face an increased risk of becoming infected, the CDC explained.
