Variants - B 1.1.7UK, B.1.351South Africa, P1 Brazil

B.1.1.7 lineage (20I/501Y.V1 VOC202012/01): Thisvariant carries a mutation in the receptor binding domain (RBD) of the spikeprotein at position 501; asparagine (N) has been replaced with tyrosine (Y) atthis position. The mutation is also termed as N501Y. This variant also carries othermutations, including -

·                    69/70deletion: spontaneously occurred several times; possibly results in aconformational change in the spike protein;

·                    P681H:spontaneously occurred several times; near the S1/S2 furin cleavage site.

The variant is tied to heightenedtransmissibility (more efficient and rapid transmission). In January this year,scientists from Britain pointed that the B.1.1.7 variant may be linkedwith increased risk of death in comparison with other variants. Early reports donot indicate that the variant affects the severity of disease or vaccineefficacy.

B.1.351 lineage (20H/501Y.V2): This variant carries several mutationsin the spike protein, which include K417N, E484K, N501Y. This variant does not carrythe 69/70 deletion. The variant was first detected in South Africa, in samples asold as from the start of October last year. Cases have been identified outsideof South Africa as well. E484K mutation in this variant may have an impact onneutralization by some polyclonal and monoclonal antibodies.

P.1 lineage (20J/501Y.V3): This variant is a branch off theB.1.1.28 lineage, first identified by the National Institute of InfectiousDiseases (NIID) in Japan among four travelers from Brazil. The samples weretested during routine screening at Haneda airport. This variant has threemutations in the spike protein RBD, including K417T, E484K, and N501Y. Evidenceindicates that some of the mutations in this variant may have an impact on itstransmissibility and antigenic profile, thus affecting the potential ofantibodies produced by a natural infection or vaccine to identify andneutralize the virus.

Some consequences of emerging variants:

·                    Potential for quicker spread: D614G mutation increases the ability of the virusto spread more quickly compared to the wild-type virus. Laboratoryexperiments have shown that 614G variants propagate more quickly in humanrespiratory epithelial cells, and outperform the 614D viruses. Data alsosuggest that the 614G variant spreads more quickly than viruses without themutation.

·                    Potential to cause milder or more severe disease in people: The B.1.1.7 variant may be tied to aheightened risk of death compared to other variants.

·                    Potential to evade detection by viral diagnostic tests: B.1.1.7 has Sgene target failure

·                    Diminished susceptibility to therapeutic agents like monoclonalantibodies: B.1.1.28

·                    Potential to evade natural or vaccine-induced immunity: B.1.1.28

Once a large population receivesvaccination, immune pressure would likely facilitate and speed up the emergenceof such variants by selecting for escape mutants.

India predictions

 1.      Deathrate is deaths today vs number of cases today.

2.          Corrected death rate is deaths todayvs number of cases 14 days back.

3.          For one symptomatic test positivecase, there are 10-30 asymptomatic cases and 20 untested cases.

4.          Estimated number of deaths = Reporteddeaths x 2.

5.          Number of deaths today should be 15%of the serious patients present 14 days back.

6.          Undocumented cases for each documentedcase - Iceland: 1: 2; Germany: 1: 5; New York City grocery store shoppers: 1:10; California: 1.5%.

7.Amongst active cases, 2.37% are serious, 1.82% need oxygen, and 0.41% needventilator support

 

Facts

 

DENSITY: India: In states withaverage population density of 1185/sq km, the average number of cases were2048. On the contrary, in states with population density of 909/sq km, thenumber of cases were 56. When Chandigarh and Pondicherry were taken out fromthis group, the Average Density of other states were 217 and the average numberof cases were 35. [HCFI] 

COVID Sutra: COVID-19 pandemic is due to SARS2 Beta-coronavirus (different from SARS 1 where spread was only in seriouscases); with over eleven virus sequences floating; Causes Mild or AtypicalIllness in 82%, Moderate to Severe Illness in 15%, Critical Illness in 3% andDeath in 2.3% cases (15% of admitted serious cases, 71% with comorbidity<Male > Females); affects all but Predominantly Males (56%, 87% aged 30-79,10% Aged < 20, 3% aged > 80); with Variable Incubation Period days (2-14;mean 5.2 days);  Mean Time to Symptoms 5 days;  Mean Time toPneumonia 9 days, Mean Time to Death 14 days,  Mean Time to CT changes 4Days, Reproductive Number R0 1.5 to 3  (Flu 1.2 and SARS 2), EpidemicDoubling Time 7.5 days; Origin Possibly from Bats (Mammal); Spreads via Humanto Human Transmission via Large and Small Droplets and Surface to Human Transmissionvia Viruses on Surfaces for up to three days. Enters through MM of eyes, noseor mouth and the spike protein gets attached to the ACE2 receptors. ACE2receptors make a great target because they are found in organs throughout ourbodies (heart muscle, CNS, kidneys, blood vessels, liver). Once the virusenters, it turns the cell into a factory, making millions of copies of itself,which are then breathed or coughed out and infect others.

 

The most important

1.    Masking is THE prevention

2.    RT PCR Ct is THE test for diagnosis

3.    Zinc is THE Vitamin

4.    Day 5 is THE dayin COVID phase for mortality prevention

5.    Day 90 is THE day after which the word COVID ends

6.    Home Isolation is THE modality ofTreatment

7.    12 years is THE age when themortality starts

8.    CRP is THE lab test for seriousness

9.    Loss of Smell is THE symptom equal toRT PCR test

10. 15 minutes is THE time to get theinfection.

 

 

Numbers to remember

Other Sutras

1.      Viralparticles are seen in tears, stool, kidneys, liver, pancreas, heart, semen,peritoneal fluid, CSF.

2.      Thrombosis:University of Pennsylvania has reported that clots are seen in patients evenon blood thinners.

3.      Otherhuman beta-coronaviruses have immunity lasting only for one year with noIMMUNITY PASSPORT.

4.      Inabsence of interventions, prolonged or intermittent social distancing (till2022-24) is the key.

5.      Dueto low levels of cross immunity from other beta-coronaviruses againstSARS-CoV-2, the virus may appear to fade away, only to show resurgence after afew years. Surveillance till 2024.

6.      Duringpeak, trace and treat, and after the peak, trace and treat the close contacts.

7.      Increasedspread: Close environment, crowded place with close physical contacts with noventilation.

8.      Strategies:From community mitigation to individual containment; broader good overindividual autonomy; perfect cannot be the enemy of the good; pandemics arefought on the grounds and not the hospitals. Treat the patient and not the testreport; consider every surface and every asymptomatic person as virus carrier.

9.  HCW:Direct patient exposure time < 30 minutes; 7 days work and 7 days holidays.

10.  Italy:mortality reduced when they were short of ventilators.

11.  Hospitalat HOME: CHF, mild pneumonia, exacerbations of asthma and COPD,cellulitis, and urinary tract infections.

12.  GreatImitator (protean manifestation).

13.  IgMcan be false positive in pregnancy, immunological diseases; Pooled tests(<5, 20 Kerala, 64 Singapore RT PCR) when seroprevalence is <2%.

14.  Earlytreatment, day 3-5, to reduce the viral load and prevent cytokine storm.

15.  Hypoxia:Low flow oxygen <6l/mt, titrated to high flow oxygen using non rebreathingmask, Venturi mask, HFNC and helmet CPAP, NIV in supine or prone position.

16.  Earlyintubation with prone ventilation only if progressive. Hypoxia (walking dead)have capillary problem and not alveoli.

 

Formulas and Predictions

 

Deaths

1.     The goal is to save lives. Monitoringdeaths is important, especially when testing is limited.

 

2.     Daily deaths are the best indicator ofthe progression of the pandemic, although there is generally a 17- to 21-daylag between infection and deaths.

 

3.     Deaths in symptomatic cases: Lessthan one percent (best of the care).

 

4.     Therefore, Deaths X 100 = expectednumber of symptomatic cases

 

5.     Some may count probable or presumptive COVID-19 deaths when casesare not confirmed with a positive test but on the basis of symptoms and medicalhistory. In New York, 3,700 presumptive deaths were added in one day in Aprilwhen testing was limited.

 

6.     Case fatality rate: Number of totaldeaths as on date/number of total RT PCR positive cases as on today

 

7.     Infection fatality rate: Number of totaldeaths as on date/number of total calculated cases as on today

 

8.     Number of reported deaths: Number ofconfirmed deaths x 2

 

Metrics

 

1.     The University ofWashingtons Institute for Health Metrics and Evaluation (IHME):

Is based on what is known about a disease and howpeoples actions may affect that.

Forecastsare not fixed but change depending on public behavior. When people learn thatnew cases are rising, they start wearing masks and using social distancing again;and when they realize that fresh cases are dropping, they tend to drop theirguard.  IHME makes use of real-timeinfection data from Johns Hopkins Universitys Coronavirus Resource Center torepresent disease transmission and estimate how many Americans will die. Theresearchers then estimate how many Americans are wearing masks or using socialdistancing, which can modulate the final model.

 

Therate of infection in a population is based on the "R0," orreproduction number. R0 represents the average number of people who willcontract the infection from a single infected person, in a population thatsnever been witness to the disease before. If R0 is 3, it suggests that one casewill create an average of three new cases. When that transmission rate ofinfection occurs at a specific time, its called an "effective R," or"Rt."  R0 less than 1 means theepidemic is under control; and when its higher than 1, it is still spreading.

 

IHMEfound the "effective R over 1 in Oklahoma. In all other states theeffective R was found to be less than 1.”

 

2.     CDC: Relies on positive tests results.CDCs report these as confirmed cases. The positivity rate suggests how tough oreasy it is to find a case, which is an indicator of both the spread of COVID-19and how widespread testing is. If the rate of positive tests is 20%, onedoesn’t have to look hard to find a case, compared to 1%, which means that onehas to do a lot of tests to get a positive one. The more COVID-19 spreads, thehigher the positivity rate. A 60% positivity rate may suggest that testing isonly being done in a nursing home during an outbreak or a hospital where themost apparent cases are and not the general population where cases may bemilder.

 

3.     Marylands COVID-19 dashboard: It reportsthe daily positivity percentage (percentage of positive tests and total testingvolume since March). While looking at testing, one wants to know how many testswere done historically with the ability to compare and understand if the numberhas increased or declined or is stable and the percentage that is positive.Maryland and Pennsylvania report a 7-day rolling average of the dailypositivity percentages. The 7-day average rate better indicates a trend ascompared to daily numbers.

 

4.      The testing numbers often fluctuate,depending on where testing is done and when the labs report test results. Asudden surge in testing numbers may point to a large number of tests done in agroup setting such as a nursing home or prison on a single day. Laboratoriesand hospitals report test results on weekdays, so the numbers can decline onweekends.

 

5.     A major goal during the coronavirusepidemic has been to flatten the curve to maintain local hospital capacity.After expected COVID-19 surges, many hospitals limited surgeries and admissionsto preserve their resources, including hospital beds, ventilators, andhealthcare personnel.  [WebMD]

  

Infrastructure Capacity

1.     Ifhospital capacity reaches 80%, we may have to stop admitting patients toprevent the hospital from being overwhelmed.

2.     Inorder to plan for surges and increase capacity: It is required to know thenumber of people who tested positive and were admitted to the hospital withsymptoms of COVID-19.

3.    Pennsylvanias COVID-19 dashboard: has a hospital preparedness page that shows the number of hospitalizedCOVID-19 patients and the number and percentage of available beds by unit,including intensive care, medical/surgical, and airborne isolation.

4.     Pennsylvania: Reports the number of ventilators COVID-19 patients andnon-COVID-19 patients use every day.

5.    Illinois lists the recovery rate: In Illinois, the recovery rate of 95%is calculated as recovered cases divided by recovered cases plus confirmed deaths.This indicates the quality of medical care and the severity of disease. [WebMD]

6.     Caseswill double after the average doubling time of the country at that time

7.     Cases expected in the community: Get number of deaths occurring in afive-day period

Estimate the number of infections required to generate these deathsbased on the country or area case fatality rate

Compare that to the number of new cases actually detected in thefive-day period.

This can then give us an estimate of the total number of cases,confirmed and unconfirmed

8.     Lock down effect: Reduction in cases after average incubation period (5days)

9.     Lock down effect in reduction in deaths: Reduction in number of deathson day 14 (average time to death of that country)

10.  Requirement of ventilatorson day 9: 1-3% of number of new cases detected

11. Requirement of future oxygen onday 7: 10% of total cases detected today

12. Number of people which can bemanaged at home care: 90% of number of cases today

13. Requirement of ventilators: 1-3%of number of cases admitted 7-9 days back

14. Requirement of oxygen beds today:10% of total cases admitted seven days back

15. Number of unreported or untestedcases: Number of reported cases x 10-30 (depending on the country, New York 10,Delhi 23.8, Pakistan 30)

16. Number of asymptomatic cases: For6 symptomatic cases, 200 asymptomatic cases (CHINA); (1.78 M tests in HongKong, 32 asymptomatic cases, 10 symptomatic cases)

17.  Oxygen requirement on thatday in the hospital at 6am: Number of cases detected to have hypoxia on sixminutes walk test.
