  3. Aug 19, 2021 · The Delta variant is more contagious: The Delta variant is highly contagious, more than 2x as contagious as previous variants. Some data suggest the Delta variant might cause more severe illness than previous variants in unvaccinated people. In two different studies from Canada and Scotland, patients infected with the Delta variant were more likely to be hospitalized than patients infected with Alpha or the original virus that causes COVID-19.

    • Delta variant is highly contagious. As of July 22, nearly 80% of UC Davis Health patients who tested positive for COVID-19 had the Delta variant. According to the CDC during the same week, the Delta variant accounted for more than 80% of new cases in the U.S. Health experts say it's typical for a new strain of a virus to be more contagious because it often becomes much more efficient and easily transmitted.
    • Delta variant symptoms are the same. The symptoms of the Delta variant appear to be the same as the original version of COVID-19. However, physicians are seeing people getting sicker quicker, especially for younger people.
    • Delta variant is affecting unvaccinated people more. Most patients hospitalized at UC Davis Medical Center are people who have not received the COVID-19 vaccine.
    • Breakthrough cases for vaccinated people are rare, but do happen. When a vaccinated person tests positive for COVID-19, most either have no symptoms or have very mild symptoms, and it rarely results in hospitalization or death.
    • Delta is more contagious than the other virus strains. One thing that is unique about Delta is how quickly it is spreading, says F. Perry Wilson, MD, a Yale Medicine epidemiologist.
    • Unvaccinated people are at risk. People who have not been fully vaccinated against COVID-19 are most at risk. In the U.S., there is a disproportionate number of unvaccinated people in Southern and Appalachian states including Alabama, Arkansas, Georgia, Mississippi, Missouri, and West Virginia, where vaccination rates are low.
    • Delta could lead to 'hyperlocal outbreaks.' If Delta continues to move fast enough to accelerate the pandemic, Dr. Wilson says the biggest questions will be about the heightened transmissibility—how many people will get the Delta variant and how fast will it spread?
    • There is still more to learn about Delta. One important question is whether the Delta strain will make you sicker than the original virus. But many scientists say they don’t know yet.
