Pandemic: What It Is and What It Means for You
A pandemic is an epidemic that reaches worldwide. The World Health Organization has specific criteria for when an epidemic becomes a pandemic.

- Viruses that cause pandemics often mutate to become less life threatening.
- The 1918 flu pandemic lasted about 18 months and ended after either people had been exposed to the virus or it became less life threatening.
- With new variants come new questions about where the pandemic is headed, and whether we will need annual boosters or modified vaccines.
Over time, pandemic viruses typically mutate and evolve into an endemic disease that circulates at lower, more manageable levels.
This was the case with the influenza strain behind the 1918 flu pandemic and some virologists hope this may be happening with SARS-CoV-2, the virus that causes COVID-19.
Early reports suggest that the Omicron variant may cause milder infections, potentially due to its unique collection of mutations along with the buildup of immunity across the globe.
Still, it’s too early to know for certain how the COVID-19 pandemic will play out.
