It’s time for our next 14-day moving average determinations for SARS-CoV-2 for the United States and my thoughts on vaccines, SARS-CoV-2 therapeutic agents and mutant viruses. We use the WORLDOMETERS aggregators data set to make any projections since it includes data from the Department of Veterans Affairs, the U.S. Military, federal prisons and the Navajo Nation.

SARS-CoV-2 infections per day in the United States have decreased for the third time in 10 weeks; however, there is still widespread underreporting by states, a failure to capture positive home tests, and a decreased PCR screening program in most states. Deaths per day in the United States have increased by 60 deaths per day. The number of infections per day has decreased by 15,124. The CDC estimates that BA.5 accounted for 79.2%, BA.4.6 accounted for 13.6%, BF.7 accounted for 4.6%,  BA.2.75 accounted for 1.8% and BA.4 accounted for 0.8%, in the week ending October 8. The rise in BA.4.6 cases is especially concerning because the September 9 UK Health Security Agency Technical Briefing says that, “Pseudoviral neutralisation assays performed on BA.4.6 show that titres are reduced 2-fold, compared to neutralisation of BA.4 or BA.5 using sera from triple dosed recipients of the Pfizer BNT162b2 vaccine.” The same briefing also states that BA.4.6 has a growth advantage relative to BA.5. The October 7 UK Health Security Agency Technical Briefing says, “From UK data, BQ.X, BA.2.75.2 and BF.7 are the most concerning variants in terms of both growth and neutralisation data at present; there is also supportive animal model data for BA.2.75.”

We frequently hear messaging from health officials and politicians that Omicron is “mild,” especially compared to the Delta variant, and as a result, many of our patients believe that they no longer need to wear their masks. This is a dangerous misconception. SARS-CoV-2 still remains a highly transmissible, airborne virus. The following graph, based on CDC data from April 2, 2022, shows that Omicron deaths in people over 65 are much higher than Delta deaths in the same age group. In fact, the peak of Omicron deaths in people over 65 years of age is 163% higher than the Delta peak. The death rate from Omicron is only lower than Delta in the populations between 12 and 64 years of age. Until we have more data on these newer mutants of SARS-CoV-2, we will not know the lethality of each variant. It may take months to measure objective differences in the death rates of new circulating variants. We recommend that all of our patients and family members continue to wear N95 masks in all enclosed spaces.
In patients treated with Paxlovid for five days who have persistent symptoms and continued positivity, we feel that clinicians should consider giving a second course of Paxlovid for five days. Boucau et al have demonstrated that in a study of seven patients with recurrent symptoms, “High viral loads (median 6.1 log10 copies/mL) were detected after rebound for a median of 17 days after initial diagnosis. Three had culturable virus for up to 16 days after initial diagnosis.” This was not due to resistance-associated mutations of the virus, suggesting that the course of therapy may be inadequate in this group of persistently infected patients.

The Omicron variant has continued to mutate just like Delta. The list of variants was not updated in the last four weeks, but as of six weeks ago, there are now 276 Omicron sub-variants that have been assigned Pango lineages, including 123 sub-lineages of BA.2, one sub-lineage of BA.3, 15 sub-lineages of BA.4, and 45 sub-lineages of BA.5. The BF lineage (new sixteen weeks ago) now has 21 sublineages. The BE lineage (also new sixteen weeks ago), with BE.1 first detected in South Africa, Austria and England, now has 7 sublineages. There are also new lineages from sixteen weeks ago: BC.1 (Japan), BC.2 (Peru), BD.1 (UK), BG.1 (Peru), BG.2 (US, Denmark, Canada), BG.3 (Peru), BG.4 (Israel). In the last eight weeks, the BG lineage has expanded to include BG.5 (USA) and BG.6 (Peru). Lastly, two new sublineages were added in the past eight weeks: BH.1 (India) and BK.1 (USA and Canada). 

In Monterey County, as of 10/7/22, 1.7% of 0-4 year-olds and 40.0% of 5-11 year-olds have received the first two doses of vaccine, while 73.2% of 12-17 year-olds have received two doses. Only 53.9% of Monterey County residents have received a third dose of the vaccine. On June 17, The FDA authorized both the Pfizer and Moderna vaccines for use in children ages 6 months to four years. We believe children under 5 should be vaccinated as soon as possible. All Monterey County residents should get up to date on COVID-19 vaccinations as soon as possible. 

On 10/07/22, the United States had 23,524 documented new infections. There were also 229 deaths. Thirty states did not report their infections, and 33 states didn’t report their deaths. In the United States the number of hospitalized patients has decreased slightly in many areas and was 30,273 on September 24, a decrease of 6,417 hospitalizations compared to the previous 14 days. On 10/07/22 there are 2,753 patients who are seriously or critically ill; that number was 3,176 two weeks ago. The number of critically ill patients has decreased by 423 in the last 14 days, while at least 6,089 new deaths occurred. The number of critically ill patients has decreased for the fourth time in twenty-eight 14-day periods. Patients are still dying each day (average 435/day). Omicron BA.4, BA.4.6, BA.5, and BF.7 variants are still causing infections. Past infections with a BA.1 or BA.2 variant will not prevent infections with any of the newer variants. 

As of 10/07/22, we have had 1,087,655 deaths and 98,523,168 SARS-CoV-2 infections in the United States. We have had 642,717 new infections in the last 14 days. We are adding an average of 321,358 new infections every seven days. For the pandemic in the United States we are averaging one death for every 90.58 infections or over 11,040 deaths for each one million infections. As of 10/07/22, thirty-eight states have had greater than 500,000 total infections, and 38 states have had greater than 5,000 total deaths. Forty-six states have had greater than 2,000 deaths, and 43 states have greater than 2,000 deaths per million population. Vermont, at 1,167 deaths per million, and Hawaii, 1,196 deaths per million, are the states with the lowest death rates. Seven states have over 4,000 deaths per million population: Mississippi (4,344), Arizona (4,315), Alabama (4,175), West Virginia (4,157), New Mexico (4,099), Tennessee (4,087) and Arkansas (4,068). . Eighteen states (Alabama, Virginia, Missouri, North Carolina, Indiana, Tennessee, Massachusetts, Ohio, Michigan, Georgia, Illinois, New Jersey, Pennsylvania, Florida, Texas, New York, Arizona and California) have had greater than 20,000 deaths. Six states have had greater than 40,000 deaths: Florida (81,566 deaths), Texas (91,394 deaths), New York (72,346 deaths), Pennsylvania (47,323 deaths), Georgia (40,374 deaths) and  California (96,418 deaths, 20th most deaths in the world). 

On 11/20/20, there were 260,331 (cumulative) deaths in the US from SARS-CoV-2. Since 11/20/20 (23 months), there were 820,654 new deaths from SARS-CoV-2. For nineteen of those months, vaccines have been available to all adults. During these eighteen months, 515,558 people have died of SARS-CoV-2 infections. Most of the hospitalizations and deaths could have been prevented by vaccination, proper masking, and social distancing. 

As of 10/07/22, California was ranked 32nd in the USA in infection percentage at 28.57%. In California, 24.60% of people were infected in the last 19 months. As of 9/23/22, 23 states have had greater than 30% of their population infected. No state has less than 20% of their population infected. 

Below are the variant proportions for Region 9, which includes California, Nevada, and Arizona. 

Worldwide, average deaths per day are 1,480 for the last 14 days, which is a 257 deaths-per-day decrease over the previous 14 days. The United States accounts for 29.39% (435 per day) of all deaths per day in the world over the last two weeks. Worldwide infections per day were 464,233. The United States accounts for 9.89% of those infections (or 45,908 infections per day). 

FDA-Approved Oral Drug Treatments for SARS-CoV-2

Pfizer has developed PAXLOVID™, an oral reversible inhibitor of C3-like protease of SARS-CoV-2. The drug inhibits this key enzyme that is crucial for virus production. The compound, also called Compound 6 (PF-07321332), is part of the drug combination PAXLOVID™ (PF-07321332; ritonavir), which just successfully completed a Phase 2-3 trial in humans in multiple countries. The preliminary results were announced on 11/5/21 by Pfizer. The results show that 89% of the hospitalizations and deaths were prevented in the drug treatment arm. The drug was administered twice a day for five days. No deaths occurred in the treatment group, and ten deaths occurred in the placebo group. The study was stopped by an independent data safety monitoring board, and the FDA concurred with this decision. Pfizer applied for an Emergency Use Authorization for this drug on 11/15/21. This drug was approved on 12/23/21. We have only been able to obtain PAXLOVID™ for two patients who we successfully treated with this drug obtained from CVS in Salinas (East Alisal Street; phone number 831-424-0026). They were expecting another shipment on 1/28/22. In my opinion, this agent, if more widely available, could markedly alter the course of every coronavirus infection throughout the world. 

Merck has developed the oral drug Molnupiravir, which induces RNA mutagenesis by viral RNA-dependent RNA polymerase of SARS-CoV-2 and other viruses. According to Kabinger et al, “Viral RNA-dependent RNA polymerase uses the active form of Molnupiravir, β-D-N4-hydroxycytidine triphosphate, as a substrate instead of cytidine triphosphate or uridine triphosphate. When the RNA-dependent RNA polymerase uses the resulting RNA as a template, β-D-N4-hydroxycytidine triphosphate directs incorporation of either guanine or adenine, leading to mutated (viral) RNA products. Analysis of RNA-dependent RNA polymerase–RNA complexes that contain mutagenesis products has demonstrated that β-D-N4-hydroxycytidine (the active form of Molnupiravir) can form stable base pairs with either guanine or adenine in RNA-dependent RNA polymerase explaining how the polymerase escapes proofreading and synthesizes mutated RNA” (quotation modified for clarity). The results of the phase 3 trial of Molnupiravir were published in the NEJM article “Molnupiravir for Oral Treatment of Covid-19 in Nonhospitalized Patients” by Angélica Jayk Bernal, M.D. et al. (December 16, 2021 DOI: 10.1056/NEJMoa2116044). In this phase 3 study in the Molnupiravir group, 28 patients were hospitalized and one death occurred. In the placebo group, 53 patients were hospitalized and 9 died. Overall, 47% of hospitalizations and deaths were prevented by Molnupiravir. If you do a post hoc analysis and just look at deaths, Molnupiravir would prevent 89% of deaths. An Emergency Use Authorization by the FDA for Molnupiravir was approved on 12/24/21.The dose of Molnupiravir approved is four 200 mg capsules orally twice a day for five days. Diarrhea is reportedly a side effect in two percent of patients. I treated my first patient with Molnupiravir on 1/28/22. Currently more Molnupiravir is available weekly in the United States than PAXLOVID™ (see chart below; data from PHE.gov). Locally Molnupiravir is still available at CVS in Monterey (Fremont Blvd.; phone number: 831-375-5135) and CVS in Salinas (East Alisal Street; phone number 831-424-0026).

FDA-Approved Intravenous Monoclonal Antibody Treatment for Non-Hospitalized SARS-CoV-2 Patients 

Bebtelovimab is a monoclonal antibody treatment for mild-to-moderate COVID-19 in adults and pediatric patients (12 years of age and older weighing at least 40 kg) with positive results of direct SARS-CoV-2 viral testing, and who are at high risk for progression to severe COVID-19, including hospitalization or death, and for whom alternative COVID-19 treatment options approved or authorized by FDA are not accessible or clinically appropriate. The authorized dose of bebtelovimab is 175 mg, given as an intravenous injection over at least 30 seconds. The U.S. Food and Drug Administration (FDA) has issued an Emergency Use Authorization (EUA) for this drug on 2/11/22. Bebtelovimab is a human antibody that demonstrates neutralization against the Omicron variants and is available in every state and many hospitals and some clinics. If you are planning on using a monoclonal antibody to treat a SARS-CoV-2 infection, currently only bebtelovimab has activity against all Omicron variants, including BA.4.6. Researchers at Columbia University recently reported that “The loss of activity of tixagevimab and cilgavimab [components of Evusheld] against BA.4.6 leaves us with bebtelovimab as the only therapeutic mAb that has retained potent activity against all circulating forms of SARS-CoV-2.” For this reason, we no longer recommend Evusheld for immunocompromised patients with Omicron infections. 

An examination of the three variants that Wang et al identified as capable of immune escape in patients who receive the two monoclonal antibodies that are contained in Evusheld reveals that all three variants have a mutation in the spike protein at position 346. The changes substitute an uncharged amino acid— threonine (T), serine (S), or isoleucine (I)—for a positively-charged amino acid, arginine. This just goes to show that a single point mutation in the spike protein can render a monoclonal antibody treatment ineffective. Policy makers should keep in mind that the only way to prevent new drug-resistant variants like BA.4.6 from emerging is to prevent transmission of SARS-CoV-2 in the first place, using non-pharmaceutical interventions. The lack of use of N95 masks, with impending winter and influenza outbreaks, on top of COVID-19, is not wise public health and infectious disease policy. If we don’t make effective use of the non-pharmaceutical interventions available to us (masks, ventilation, social distancing), then the pharmaceutical interventions we have will all eventually be useless. 

Two virologists collaborated on Twitter to create the figure below, which Professor Johnson titled “Convergent Evolution on Steroids.”  It shows the key mutations present in many of the currently-circulating Omicron subvariants and demonstrates that mutation at site 346 is becoming more and more common. This means that even if prevalence of BA.4.6 wanes, we are still likely to have drug resistance issues with other newer variants. 

Watching World Data

Over the next few months, we’ll be paying close attention to correlations between the SARS-CoV-2 data, the number of isolates identified in various countries and states, and the non-pharmaceutical interventions (like mask mandates and lockdowns) put in place by state and national governments. Data on infections, deaths, and percent of population infected was compiled from Worldometers. Data for this table for SARS-CoV-2 Isolates Currently Known in Location was compiled from GISAID and the CDC. It’s worth noting that GISAID provided more data than the CDC.
