11/20/2023 0 Comments Provincetown covid outbreak![]() Covid vaccines remain extremely effective against the worst outcomes of the disease - hospitalization and death - and breakthrough infections remain uncommon. With the Delta variant pushing US Covid cases back up, fully vaccinated people are wondering whether they need to start masking indoors again. People shop at a grocery store enforcing the wearing of masks in Los Angeles on July 23, 2021. 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.”Įven 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. It also notes that “asymptomatic breakthrough infections might be underrepresented” because they are less likely to be detected.Įarlier this week, Walensky said that ongoing outbreak investigations will help uncover more about what happens when these breakthrough infections do occur. The new report says that “microbiological studies are required to confirm these findings” of similar viral loads among breakthrough infections. Gandhi said there are multiple parts to the immune system – including antibodies and T cells – that raise important questions around using viral load, which is measured by PCR tests, as a proxy for how contagious someone is. How does the new CDC mask guidance change how families stay safe from Covid-19? An expert's take Jenna Watson/The Indianapolis Star/USA Today Network ![]() The CDC recommends students and teachers wear masks while at school. Monica Gandhi, an infectious disease specialist at University of California, San Francisco, who was not involved in the research. “This is intriguing data, it’s important, but I’m not positive that you’re equally as infectious if you’re vaccinated,” said Dr. The CDC document also cited reports indicating the variant might cause more severe disease, as well.īut even with similar viral loads, it’s not a foregone conclusion that vaccinated people are necessarily as contagious as unvaccinated people. 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. What's different about the Delta variant? Here's what's known (Photo by Spencer Platt/Getty Images) Spencer Platt/Getty Images Currently, about 54 percent of New Yorkers have taken the vaccine. Due to the rapidly spreading Delta variant, New York City Mayor Bill de Blasio has announced that the city will require all city workers to be vaccinated or tested weekly for COVID-19. NEW YORK CITY - JULY 26: People walk out of a store requesting that people wear masks on Jin the Brooklyn borough of New York City. ![]() 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. “The masking recommendation was updated to ensure the vaccinated public would not unknowingly transmit virus to others, including their unvaccinated or immunocompromised loved ones.” The finding that the Delta variant resulted in similar viral loads “was a pivotal discovery leading to CDC’s updated mask recommendation,” Walensky said Friday. Over 75% of the US population live in these areas. On Tuesday, Walensky previewed these findings while unveiling guidance that people in areas with “high” or “substantial” Covid-19 transmission should resume wearing masks indoors. In a new report, the CDC shares details from a Covid-19 outbreak around Provincetown, Massachusetts, shown here in 2020. ![]()
