The study suggests that "even jurisdictions without substantial or high COVID-19 transmission might consider expanding prevention strategies, including masking in indoor public settings regardless of vaccination status." Between July 3 and 17, daily new cases rose from a 14-day average of 0 to 177 cases per 100,000 residents. Thousands gathered for summer festivities, and infected people reported going to "densely packed indoor and outdoor events at venues that included bars, restaurants, guest houses, and rental homes," the study says.Īlthough these findings motivated CDC to update its guidance for areas with higher levels of viral transmission, the study notes that Barnstable County was not one of those areas until the outbreak. The vaccinated individuals ranged in age from 20 to 70, and two had underlying health conditions.Īdditional infections were identified among visitors from at least 22 other states who visited the area from July 3 through 17. Of those five, one person was unvaccinated and had underlying medical conditions, and four were vaccinated. "Getting vaccinated continues to prevent severe illness, hospitalization and death - even with delta," Walensky said this week.Īmong the Massachusetts residents in the latest study, none died and only five were hospitalized. The CDC internal document estimated that vaccines reduce the risk of severe disease or death 10-fold or greater, and they reduce the risk of infection three-fold. Moreover, vaccinated people are far less likely to end up in the hospital. "But again, I want to reiterate, we believe the vast majority of transmission is occurring in unvaccinated people and through unvaccinated people." Even more reason to get vaccinatedĮven with delta, COVID-19 vaccines still reduce the spread of the virus. "We are now continuing to follow those clusters to understand the impact of forward transmission of those vaccinated people," she said. The CDC document also cited reports indicating the variant might cause more severe disease, as well. Measles, chickenpox, this - they're all up there," Walensky told CNN late Thursday. "It's one of the most transmissible viruses we know about. But now, with delta, that number could be five to nine. This means that, under certain conditions, an infected person may have transmitted to two or three people, on average, early in the outbreak. On Thursday, a CDC internal document said the delta variant was roughly as transmissible as as chickenpox, whereas an early strain was closer to the common cold. Earlier this month, for example, Chinese scientists described viral loads that were about roughly 1,000 times higher with delta than earlier strains. Not only did vaccinated people tend to have lower viral loads, but they also had milder symptoms and were sick for less time.īut research has shown that delta spreads more aggressively. ![]() Prior to delta, vaccination was known to impact factors that likely influence transmission. Genetically sequenced cases revealed the delta variant as the main culprit. No deaths were reported among them.Ībout 74% - or 346 cases - had been fully vaccinated. The study, published by CDC Friday, describes 469 Massachusetts residents who were infected in a July outbreak in Barnstable County, which includes the summer vacation destination Provincetown. Rochelle Walensky, director of the US Centers for Disease Control and Prevention, said in a statement Friday. "High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with delta can transmit the virus," Dr. A new study shows the delta COVID-19 variant produced similar amounts of virus in vaccinated and unvaccinated people if they get infected - illustrating a key motivation behind the federal guidance that now recommends most fully vaccinated Americans wear masks indoors.Įxperts say that vaccination makes it less likely that you'll catch COVID-19 in the first place - but for those who do, this data suggests they could have a similar tendency to spread it as unvaccinated folks. The CDC is set to release data that led to new masking guidance amid concerning spread of the COVID delta variant.ĬAPE COD, Mass. ![]()
