Key Concepts

Virulence

Virulence refers to the degree of pathogenicity of a microorganism, indicating its ability to cause disease. It encompasses factors such as the organism's capacity to invade host tissues, evade the immune system, and produce toxins. Understanding virulence is crucial for ranking viruses based on their potential to cause severe illness or death.

Transmission Routes

Transmission routes describe how viruses spread from one host to another, which can significantly impact their deadliness. Common routes include respiratory droplets, direct contact, and vector-borne transmission. Analyzing these routes helps assess the potential for outbreaks and the overall impact of a virus on public health.

Case Fatality Rate (CFR)

The case fatality rate (CFR) is a measure that indicates the proportion of deaths from a specific disease compared to the total number of diagnosed cases. It is a critical metric for evaluating the deadliness of a virus, as a higher CFR suggests a more lethal pathogen. Understanding CFR helps in prioritizing public health responses and resource allocation.
