Here is why higher fatality rates often correspond to lower spread:
- Host Impairment: Viruses need a living host to replicate and spread. Highly fatal diseases (like Ebola or Nipah) often make the host so sick that they become bedridden, reducing contact with others.
- Rapid Death/Severity: If a virus kills the host before or immediately after symptoms start, it has a limited time frame for transmission.
- Faster Identification and Isolation: Diseases that cause severe symptoms or high mortality are usually easier to identify quickly, allowing health authorities to quarantine victims and break the chain of transmission, as shown in this NPR article.
- Asymptomatic Transmission: Viruses that spread easily, like the common cold or COVID-19, often have lower fatality rates because they allow infected individuals to remain mobile and asymptomatic (or mildly symptomatic) for a period, maximizing the opportunities to spread, notes a discussion on Reddit.
