Unfortunate news, everyone. It seems that the coronavirus is not going to disappear anytime soon, according to health experts. A recent poll conducted by Nature magazine indicated that about 90% of scientists believe COVID-19 is likely to become endemic.
While the number of reported cases and deaths has decreased, they still remain higher than during the initial peak. Even with vaccinations underway and some states cautiously reopening—though Texas and Mississippi are not exactly models of caution—COVID-19 appears to be a lasting presence.
Dr. Samuel Carter, a prominent infectious disease specialist, recently mentioned that it’s “possible” we may still need to wear masks well into 2022. Personally, I believe adopting a mask culture could benefit us. The U.S. accounts for about 1 in 5 global COVID-19 deaths, whereas many East Asian countries have a long-standing tradition of wearing masks, resulting in significantly lower death rates.
But what does “endemic” really mean? If you think the term pandemic is overused, prepare for endemic to enter your vocabulary in Year 2 of this pandemic. The CDC defines endemic as a persistent presence or expected level of a disease within a specific population and geographic area. Essentially, it means the disease is always around and quite common—like that persistent cold you can’t shake.
So, what are the implications of COVID-19 becoming endemic? Are we destined to remain in perpetual lockdown? The short answer is that it depends. Our future with COVID-19 as a constant element in our health landscape will rely on how the virus mutates and the immunity we develop through infection, reinfection, and vaccination.
Vaccinations and the Path Forward
While it would be fantastic if the vaccine could eradicate the SARS-CoV-2 virus within a year or two—as seen in places like Western Australia where life has returned to normal—this is unlikely. New variants from the U.K., South Africa, and Brazil are emerging, and while current vaccines seem effective against them, a variant may eventually arise that they can’t handle.
Let’s assume there was a super-vaccine capable of addressing all variants; even then, a return to pre-pandemic life wouldn’t happen overnight. To achieve herd immunity—where a significant portion of the population is immune—vaccination rates would need to reach approximately 55% to 67%, depending on various factors like transmission rates and vaccine efficacy.
Moreover, vaccinating a significant portion of the population poses challenges, especially in countries where access to vaccines is limited. History shows that diseases like polio, which were widespread in the U.S. until the 1970s, can still pose risks if vaccination rates drop.
Possible Outcomes
One reasonable scenario is that as immunity builds through vaccinations or natural infections, symptoms of COVID-19 will become milder over time. Pregnant individuals could be vaccinated to provide protection for their newborns, and children would likely encounter the virus at a young age when it typically presents with mild symptoms.
Alternatively, COVID-19 could evolve into an illness similar to the flu, requiring annual vaccinations to keep up with new variants.
The virus’s persistence will also depend on its presence in animal populations, as diseases like Ebola and yellow fever have animal reservoirs that allow them to return to humans.
Ultimately, many variables will shape a future where COVID-19 is endemic. It’s crucial for countries, particularly the U.S., to maintain strategies to flatten the curve and limit virus spread; otherwise, we could see a significant worsening of the pandemic.
Get vaccinated. Wear a mask. Let’s push toward a future where COVID-19 transitions from a pandemic to an endemic state.

Summary: COVID-19 is likely to become endemic, meaning it will persist in the population at a certain frequency. The future of COVID-19 depends on virus mutations, immunity development, and vaccination rates. While we may not return to pre-pandemic life immediately, adopting preventive measures can pave the way for managing the virus more effectively.
