Deciphering the R-Value

Explore the significance of the R-value in understanding disease transmission:

What is the R-Value?

Learn about the mathematical term "R nought" and its implications:

  • Understand that the R-value indicates the contagiousness of an infectious disease.
  • Recognize it as a crucial factor in policy decisions for implementing control measures.

Interpreting R-Values

Decipher the meaning of different R-values:

  • Know that an R-value of 5 suggests rapid and widespread transmission of the virus.
