Spread of an infection from one person to another
Human-to-human transmission (HHT) is an epidemiologic vector ,[ 1] [ 2] [ 3] [ 4] [ 5] [ 6] [ 7] [ 8] especially in case the disease is borne by individuals known as superspreaders . In these cases, the basic reproduction number of the virus, which is the average number of additional people that a single case will infect without any preventative measures, can be as high as 203.9.[ 9] [ 10] Interhuman transmission is a synonym for HHT.[ 11]
The World Health Organization designation of a pandemic hinges on the demonstrable fact that there is sustained HHT in two regions of the world.[ 12]
