Breakthrough infections accounted for about 40% of all cases reported in Massachusetts last week. The Massachusetts Department of Public Health has tracked a cumulative 19,443 confirmed COVID-19 infections among those fully vaccinated in the state to date and a total of 144 deaths.
At least 125,000 fully vaccinated Americans have tested positive for Covid and 1,400 of those have died, according to data collected by NBC News. The total number of breakthrough cases is likely higher than 125,683, since nine states, including Pennsylvania and Missouri, did not provide any information, while 11, like Florida, did not provide death and hospitalization totals. Four states gave death and hospitalization numbers, but not the full tally of cases.
Scientists researching the Provincetown, Cape Cod Covid outbreak reported that 79 percent of the breakthrough infections were symptomatic. Four of five people who were hospitalized were fully vaccinated.
The CDC study “raises the very worrisome possibility that high viral loads can occur in people who have Delta, and this is a fundamental as we have to approach the fall and winter,” said David O’Connor, a professor of pathology and laboratory medicine at the University of Wisconsin School of Medicine and Public Health.
As of Thursday, 882 people were tied to the Provincetown outbreak. Among those living in Massachusetts, 74% of them were fully immunized, yet officials said the vast majority were also reporting symptoms. Seven people were reported hospitalized.
New infections among Cambridge residents have increased in July, with 83 confirmed and probable cases reported so far this month (July 1-20), according to the Cambridge Public Health Department. Of these 83 confirmed or probable cases, 42% were vaccine “breakthrough” cases, meaning they were fully vaccinated but still got infected.
More than 5,000 breakthrough COVID infections have been reported in Massachusetts, according to the latest Department of Public Health data. A total of 5,166 breakthrough cases have been reported through July 17, resulting in 80 deaths. A week ago, there were 4,450 cases and 79 deaths reported among fully vaccinated people.

There have been more than 4,300 breakthrough cases reported in Massachusetts as of May 31, according to the state Department of Public Health.
4,300 breakthrough cases is an increase of about 28% on the last figure of 3,343 breakthrough cases reported in Massachusetts on the 23rd May 2021:
All three global VoCs (B.1.1.7, B.1.351, and P.1) have now been detected in MA. However, unlike B.1.1.7 and B.1.351, P.1 has shown a rapid rise in frequency in the few weeks following its first detection on March 16th, 2021. Phylogenetic analysis of these 54 P.1 genomes from MA, alongside four additional P.1 genomes from neighbouring states (two from Connecticut (CT) and one each from Maine (ME) and Rhode Island (RI)) and 895 other global P.1 sequences from GISAID, 6 1 suggests at least six introductions of P.1 into MA and at least eight introductions of P.1 into the New England region, likely from both international and domestic sources.

Researchers have developed a new artificial intelligence (AI) system which they claim can detect coronavirus by analysing the sound of people coughing.
Scientists at Massachusetts Institute of Technology (MIT) said the AI works because the virus causes temporary muscular impairment which can cause small differences to people’s speech or the sound of their cough – even if they have no other symptoms.
