Limited data suggest rising global COVID-19 activity
Though case reporting doesn't accurately reflect COVID-19 activity because of decreased testing and reporting, the number reported over the past month increased by 63%, with increased cases reported in three regions, the World Health Organization (WHO) said in its latest weekly update yesterday.
During an online Q and A session today, Maria Van Kerkhove, PhD, the WHO's technical lead for COVID, said the latest update is the WHO's final weekly report as it transitions to monthly reporting.
[This is colossally stupid. Cases are going up and the reporting is going down. Who designed this x for deniability?]
Over the past month, only 44% of countries reported any cases to the WHO,...Of the 19 countries that regularly report data on hospitalization for COVID, eight reported increases of 20% or more compared to the previous month:

Study helps explain SARS-CoV-2 variants' rapid spread
"The omicron variants that have become dominant over the past year, such as BQ.11 and XBB.1.5, have high affinity for the receptor on host cells, angiotensin-converting enzyme 2, and they are able to fuse with the cell membrane and invade much more efficiently than previous SARS-CoV-2 omicron variants," Veesler said.
They have also been able to reinfect people who had been infected by earlier variants and break through the immune protection of vaccines designed to protect against the earlier variants. These reinfections and breakthrough infections are possible because the new variants can evade antibodies induced by exposure to the earlier variants, Veesler and his colleagues found. Such antibodies, called neutralizing antibodies, prevent infection by quickly clearing an invading virus before it can become established.
However, the researchers also found that previous infection or vaccination did help to generate antibodies that recognized some of the proteins found on newer variants. These antibodies successfully activate immune cells that eradicate infection by killing and eliminating infected cells.
This immune response may explain why previous exposure to earlier variants or vaccination against them appears to reduce the risk of serious illness, hospitalization, and death with reinfection by a newer variant, Veesler said.

Clotting proteins linked to Long Covid’s brain fog
Study of unvaccinated people hospitalized with COVID-19 bolsters theory that blood clots may contribute to cognitive problems months later
Science. BYCATHERINE OFFORD 31 AUG 2023
Along with physical fatigue, “brain fog” has become one of the best known manifestations of the condition known as Long Covid. Yet it’s still unclear why some people infected with SARS-CoV-2 develop cognitive problems—which can include trouble concentrating and remembering—and others don’t. Now, a large study of people hospitalized with COVID-19 early in the pandemic has identified two proteins involved in blood clotting, fibrinogen and D-dimer, that are associated with cognitive deficits up to 1 year postinfection.
The findings, published today in Nature Medicine, are an “important advance” for scientists’ understanding of how Long Covid develops, says Steven Deeks, a physician-scientist at the University of California, San Francisco (UCSF), who was not involved in the work. Combined with previous research, the study supports the theory that blood clots triggered during the acute stages of viral infection could lead to lingering symptoms such as brain fog. Deeks cautions, however, that the study’s focus on unvaccinated people who had severe COVID-19 may limit relevance for the wider population; many people with Long Covid had milder initial infectihttps://www.science.org/content/article/clotting-proteins-linked-long-covid-s-brain-fogons—they aren’t represented in the research.

COVID infection risk rises the longer you are exposed — even for vaccinated people
Rigorous evidence shows that significant contact with a person with SARS-CoV-2 is more likely to lead to transmission than a short encounter.
Nature Anil Oza 30 August 2023
Prolonged exposure in close proximity to someone with COVID-19 puts people at high risk of catching the disease, even if they’ve had both the disease and vaccinations against it, a study1 shows.
The study, published this month in Nature Communications, reveals that the greater a person’s exposure to SARS-CoV-2, the more vulnerable they are to infection, regardless of their vaccination status. This relationship has long been suspected, but the study is one of the first to document it.
The findings point to the importance of masking, improved ventilation and other measures that reduce exposure to the virus, says Akiko Iwasaki, an immunobiologist at Yale University in New Haven, Connecticut, who was not part of the study.
The finding “just makes intuitive sense,” she says. “But now there’s evidence that these [measures] are probably going to be important to help the vaccine-mediated immunity work for you.”
Close contacts
Scientists have speculated since the start of the pandemic that the likelihood of SARS-CoV-2 infection correlates with the amount of virus that a person is exposed to. But verifying this relationship has been difficult because of the challenges in quantifying how much time people spend in close contact with others, and in tracking infections after such contact.

Native Americans at outsized risk of severe COVID-19, death
An observational study published yesterday in PNAS Nexus reveals that American Indian/Alaska Native (AI/AN) COVID-19 patients were three times more likely to become severely ill than their White or Hispanic peers and had more than double the risk of in-hospital death—despite being younger and having fewer chronic conditions.

Long Covid:
Experts encourage US states to create legislation aimed at improving indoor air quality in public spaces
Model State Indoor Air Quality Act as a legal framework for states and localities to implement legislation to allow for IAQ inspections and publicly posted monitoring results, actions that will lead to improved IAQ in public buildings.
The model act provides a comprehensive framework for states to create legislation aimed at improving IAQ by:
- Setting up a state advisory council to set standards appropriate for states' needs.
- Requiring indoor air quality be measured and the results posted publicly.
- Establishing a system for people to report health impacts potentially caused by bad air and for the state to investigate these reports and order necessary fixes.

Drugs and Vaccines:
Should I wait until October for my shot?
While scientists evaluate the effectiveness of the updated COVID vaccines, the CDC urges people to get their shots this fall to reduce the risk of severe illness and hospitalization.
"It may not be as good as if we had a specific vaccine designed for that variant with its mutations," but the updated vaccines should offer some decree of cross protection immunity, Dionne says.
While there was an uptick in COVID cases this summer, winter is when the illness typically spreads widely as people gather indoors and for holiday celebrations.
"COVID does not have the same seasonality as flu, where we see very little in the summer," Dionne says.
"But it does seem to have a degree of seasonality where we do see more cases in the winter, which probably has to do with the increased risk of transmission," he says.
To time vaccinations to achieve full effectiveness in advance of holiday gatherings that start in November, both Dionne and Maniar say people might want to wait to be vaccinated until later in October, just before Halloween.
It typically takes about two weeks to get a full vaccine response, although it may be shorter for a booster, Dionne says. "A week or two weeks is probably on the safer end to have that full antibody response."
