The Rt is between 1 and 2.
This is because each infected person is infecting approximately 1 to 2 other individuals, based on the spread of the disease shown in the diagram.
A contagious viral disease has been in a population for a while. The diagram shows a sample of the population so epidemiologists can understand how the virus is currently spreading. The red squares are infected people that are spreading the disease. Some people in the sample have been vaccinated for the disease or have had the disease already and are immune (yellow circles) while others are healthy but not immune (blue triangles). Dashed arrows show contact with an infected person that did not result in new infection, and solid arrows show contact with an infected person that did result in transmission of the disease.
Given how the disease is spreading, what is the current Rt for the virus shown in the diagram?
Choose one:
The Rt is between 2 and 3.
The Rt is 2.
The Rt is between 1 and 2.
The Rt is 3.
