Highly fatal diseases (like Ebola or Nipah) often make the host so sick that they become bedridden, reducing contact with others.</li> <li data-xf-list-type="ul">Rapid Death/Severity: If a virus kills the host before or immediately after symptoms start, it has a limited time frame for transmission.</li> <li data-xf-list-type="ul">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 <a href="https://www.npr.org/2018/05/29/615079779/why-it-s-difficult-for-viruses-to-turn-in-to-deadly-pandemics" target="_blank">NPR article</a>.</li> <li data-xf-list-type="ul">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 <a href="https://www.reddit.com/r/AskBiology/comments/fvh5ij/why_is_fatality_rate_often_inversely_related_to/" target="_blank">Reddit</a>.
