COVID news and more 11/11/23
This week, COVID cases stopped their decline and are just starting to creep up again from HV.1 and newcomer HK.3. HK.3 is a descendent of XBB, so the new fall COVID vaccines should help protect against it. Biobot shows an increase in the midwest and western United States. Emergency department visits for COVID are decreasing as other respiratory viruses (RSV, influenza) are starting to increase. Influenza levels are still low, but are starting to increase. It would be a good time to get a flu vaccine and a COVID XBB.1.5 updated vaccine for protection before Thanksgiving. COVID hospitalizations have plateaued.
Figure from Biobot. Wastewater SARS-CoV-2 virus is increasing in the midwest and west.
JN.1 (BA.2.86 + L455S) is increasing by 115% per week in Paris, France and appears to have a growth advantage over other variants. The CDC has lumped together JN.1 and BA.2.86 with BA.2 for their reporting which is confusing. BA.2.86 has 33 more mutations in the spike protein than BA.2, and JN.1 has 34 mutations with the additional L455S mutation.

A group of 212 scientists from 15 countries are working together on the COVID Moonshot, an open-science drug discovery project to try to find the best antiviral medications to fight SARS-CoV-2. Ensitrelvir, the recently approved antiviral in Japan, was identified in part from crystallographic data from the COVID Moonshot Consortium.
A new CDC report shows that Influenza vaccination coverage was 81% among Health Care Personnel (HCP) at acute care hospitals and 47% among those at nursing homes in the U.S. last year. In comparison, only 17% of HCP at acute care hospitals and 23% at nursing homes were up-to-date on COVID-19 vaccination during the 2022–23 influenza season. Improving vaccination coverage of healthcare workers can protect them and also their patients from COVID infections.
Mucosal vaccines are sprays that go directly into the nose or are inhaled into the nose, upper airways and lungs. They can cause mucosal immunity which prevents a virus from being able to enter the body. A new study from the NIH Vaccine Research Center shows again that mucosal boosters work. Virus-vectored mucosal booster vaccines (nasal or nebulized vaccine) were given to Rhesus macaques (monkeys) who had previously received 2 doses of mRNA vaccine injections. They were then challenged with a new variant (XBB.1.16). The mucosal booster vaccines had superior and durable immunity against the new and highly transmissible variant (XBB.1.16) as compared to an intramuscular booster vaccine.
Immune imprinting, also known as the “original antigenic sin”, is the theory that the immune system tends to “remember” the first antigen that it sees (i.e. the first SARS-CoV-2 virus from 2020) and continues to make antibodies for that variant instead of antibodies against new strains that may appear. A new review article looks at evidence both for and against immune imprinting in host response (antibodies) to SARS-CoV-2 and implications for booster vaccines. In another article this week, scientists evaluated different human antibodies for SARS (a.k.a. SARS-CoV-1) and SARS-CoV-2 to try to find neutralizing antibodies that would work against the entire family of sarbecoviruses. This knowledge could allow us to make a universal vaccine against all sarbecoviruses in the future.
Long COVID
“Long COVID is hard.” David Putrino recently spoke with CNN’s Dr. Sanja Gupta on his podcast about Long COVID- the symptoms, statistics, brain changes and more. Dr. Putrino relayed five tips to help people with Long COVID:
Rest and pace yourself https://buff.ly/3u9v3kG
Get evaluated for dysautonomia https://buff.ly/467sVY2
Mast Cell Activation Syndrome (MCAS) https://buff.ly/3uavICF
Breathwork- “Dysfunctional breathing and altered gas exchange is present in a majority of people with long Covid, and a daily breathwork practice can significantly improve daily symptoms. https://buff.ly/3MCfTe4
Reach out to others as chronic illnesses like Long COVID can be isolating. https://buff.ly/47quL7h
Many people lost their sense of smell and even their sense of taste with COVID infections early in the pandemic. A study looked at the loss of smell (anosmia) at 1, 2, and 3 years after infection and found that most people regained their sense of taste, but about 3.4% of people still had a decreased ability to smell (hyposmia) at 3 years as compared to controls.
In an interview with Medscape, Dr. Ziyad Al-Aly recently summarized some of the data on Long COVID. Long COVID is not uncommon. Second and third infections increase the risk of Long COVID, but vaccination can help to decrease the risk somewhat. Long COVID has become a chronic disease for many and at this point, there is no cure for Long COVID. Treatments now focus on managing symptoms. Long COVID is a complex disease and is often multisystemic. It can be different for each person affected, although there are several phenotypes.
A small case series from Yale shows that 8 patients treated IVIG for 9 months had significant improvement of post-COVID Small Fiber Neuropathy. This is initial evidence that small fiber neuropathy (SFN) may respond to IVIG and is linked with neurovascular dysregulation and dysautonomia. A larger clinical trial is needed.
In people with Long COVID from the first pandemic wave who were initially immunonaive to SARS-CoV-2, blood CD4+ T cell count levels independently correlate with Long COVID fatigue severity, regardless of the initial disease severity. Although non-hospitalized patients had fewer organ complications, they did have comparable levels of fatigue, depression, anxiety, and overall quality of life impairment. Elevated activated B cells and exhausted T cells may suggest persistent SARS-CoV-2 antigen per Dr. Iwasaki in a past tweet thread.
A new meta-analysis of 13 studies shows that pre-existing asthma or allergic rhinitis may increase the risk of Long COVID. In response to this article, Dr. Blitshteyn of the Dysautonomia Clinic posted that “this meta-analysis confirms my clinical observation that pre-existing allergies, asthma or other features of mast cell hyperactivity may be risk factors for Long Covid. Another probable risk factor is joint hypermobility syndrome that may be undiagnosed. Finally, in our paper early in the pandemic describing the first and largest case series of POTS and other autonomic disorders after Covid, some patients with Long Covid had a history of concussion, migraine and minor autonomic symptoms, such as dizziness or palpitations, before Covid.”
There are different types of Long COVID. Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a serious disease with symptoms of exhaustion, post-exertional malaise (severe fatigue or illness after trying to do common activities), cognitive dysfunction (brain fog), sleep problems and pain. There is an ME/CFS type of Long COVID that is more common in younger women and is seen more often after a mild COVID infection.
But, there are other Long COVID subtypes such as those people who initially have a severe initial COVID infection requiring hospitalization. These Long COVID patients tend to be older and male. A new study from China looks at Long COVID after severe COVID infection requiring hospitalization, studying plasma proteins at 6-months, 1-year, and 2-years. The proteomic results showed 4 types of biologic pathways affected: 1) cell–matrix interactions and cytoskeletal remodeling and hypertrophic cardiomyopathy, 2) immune responses related to the complement and coagulation cascade and cholesterol, 3) Fc receptor signaling, and 4) neuron generation and differentiation.
NIH funding for Long Covid research has run out and there are still no approved treatments for the millions of people with Long COVID. On Tuesday November 14th, people with Long COVID and their allies will be calling their congressional representatives to demand a Long COVID Moonshot with annual funding of $1 Billion for research, including clinical trials, on Long COVID. They are also asking for support for 3 bills to support educating healthcare providers about Long COVID and the establishment of Long COVID clinics. If interested, you can call on November 14th or you can email your senators and representatives now. Easy instructions on what to do are available at https://longcovidmoonshot.com/
In an interview with Dr. Emily Mendenhall posted yesterday, Dr. Fauci relayed how important it is to fund research on postviral diseases like ME/CFS and Long COVID. He recommended stable multi-year funding for Long COVID research which aligns with what people with Long COVID are asking for with the Long COVID Moonshot.
In non-COVID news, private equity firms are buying up nursing homes (and medical practices) with penny-pinching mandates that can be very dangerous for patients. Because they are not publicly traded companies, private equity firms are effectively invisible to investors, the media, and to regulators. A tuberculosis outbreak has been linked to the California Grand Casino in Pacheco, California. Fruit puree pouches for children (WanaBana and other brands) have been recalled because they may be tainted with lead.
The CDC has warned of a 755% increase in congenital syphilis from 2012 to 2021. Syphilis transferred from a pregnant individual to their fetus can lead to stillbirth, miscarriage, or neonatal death, blindness, deafness, developmental delay, or bone abnormalities. Routine prenatal care includes testing for syphilis and Bicillin is an effective treatment. Better outreach could help women get early prenatal care which is important to reduce the rate of congenital syphilis.
Liv Boeree warned in her recent TED talk about artificial intelligence (AI) and the dangers of the “Moloch's trap” of unhealthy competition. The astrophysicist turned professional poker player turned science communicator gives advice on how to avoid this trap. Tens of thousands of ancient coins dating back to the 4th century were found off the coast of Sardinia. Kenya declared a surprise public holiday on November 13th for a national campaign to plant 15 billion trees to combat climate change.
Happy Veterans Day and thank you to all veterans for your service.
Have a great rest of your weekend,

“Fauci emphasized to me how important it is to do more research on postviral syndromes and, specifically, on how long COVID affects people differently.”
"But the key, he said, would be the kind of long-range, multiple-year funding that isn’t necessarily dependent on a result for renewal—the type of funding that has existed in the past where so long as the work was good, he said, the researcher’s job would be safe. We talked about how current funding structures don’t really support this kind of open-ended research."
