Overall, 181 or (13 percent of the total survey takers) reported testing positive for COVID-19, and 52 percent of the COVID-positive responders indicated it was their first known bout of COVID-19. Nearly all of the survey takers, 1,435 (99.4 percent), reported having received at least one COVID-19 vaccine. But 70 percent of the survey takers reported going unmasked during the gathering. The CDC notes that the conference occurred when transmission levels were low, during which the CDC does not recommend wearing masks.
The agency highlighted that none of the infected conference attendees were hospitalized, though 49 respondents (27 percent) reported taking antiviral medications for their infection.
“[T]he findings of this rapid assessment support previous data that demonstrate that COVID-19 vaccines, antiviral treatments, and immunity from previous infection continue to provide people with protection against serious illness,” the agency wrote. “CDC continues to recommend that everyone ages six months and older stay up to date with all COVID-19 vaccines, including receiving an updated vaccine.”
Still, according to an advisory seen by The Washington Post, the CDC is warning attendees of an upcoming conference the agency is holding at the same hotel venue in June about the outbreak at the event in April. The CDC is encouraging attendees of the June event to wear their “own high-quality masks and, if possible, also carry COVID-19 rapid tests with them.” Spokesperson Kristen Nordlund said that the agency will also have masks on hand.
