Ground Zero: Wuhan - in live animal market or cafeteria for animal pathogens: 10th January, 2020; Total cases are based on RT PCR, 67% sensitivity
Variants - B 1.1.7 UK, B.1.351 South Africa, P1 Brazil
B.1.1.7 lineage (20I/501Y.V1 VOC 202012/01): This variant carries a mutation in the receptor binding domain (RBD) of the spike protein at position 501; asparagine (N) has been replaced with tyrosine (Y) at this position. The mutation is also termed as N501Y. This variant also carries other mutations, including -
- 69/70 deletion: spontaneously occurred several times; possibly results in a conformational change in the spike protein;
- P681H: spontaneously occurred several times; near the S1/S2 furin cleavage site.
The variant is tied to heightened transmissibility (more efficient and rapid transmission). In January this year, scientists from Britain pointed that the B.1.1.7 variant may be linked with increased risk of death in comparison with other variants. Early reports do not indicate that the variant affects the severity of disease or vaccine efficacy.
B.1.351 lineage (20H/501Y.V2): This variant carries several mutations in the spike protein, which include K417N, E484K, N501Y. This variant does not carry the 69/70 deletion. The variant was first detected in South Africa, in samples as old as from the start of October last year. Cases have been identified outside of South Africa as well. E484K mutation in this variant may have an impact on neutralization by some polyclonal and monoclonal antibodies.
P.1 lineage (20J/501Y.V3): This variant is a branch off the B.1.1.28 lineage, first identified by the National Institute of Infectious Diseases (NIID) in Japan among four travelers from Brazil. The samples were tested during routine screening at Haneda airport. This variant has three mutations in the spike protein RBD, including K417T, E484K, and N501Y. Evidence indicates that some of the mutations in this variant may have an impact on its transmissibility and antigenic profile, thus affecting the potential of antibodies produced by a natural infection or vaccine to identify and neutralize the virus.
Some consequences of emerging variants:
- Potential for quicker spread: D614G mutation increases the ability of the virus to spread more quickly compared to the wild-type virus. Laboratory experiments have shown that 614G variants propagate more quickly in human respiratory epithelial cells, and outperform the 614D viruses. Data also suggest that the 614G variant spreads more quickly than viruses without the mutation.
- Potential to cause milder or more severe disease in people: The 1.1.7 variant may be tied to a heightened risk of death compared to other variants.
- Potential to evade detection by viral diagnostic tests: 1.1.7 has S gene target failure
- Diminished susceptibility to therapeutic agents like monoclonal antibodies: 1.1.28
- Potential to evade natural or vaccine-induced immunity: 1.1.28
Once a large population receives vaccination, immune pressure would likely facilitate and speed up the emergence of such variants by selecting for escape mutants.
- Death rate is deaths today vs number of cases today.
- Corrected death rate is deaths today vs number of cases 14 days back.
- For one symptomatic test positive case, there are 10-30 asymptomatic cases and 20 untested cases.
- Estimated number of deaths = Reported deaths x 2.
- Number of deaths today should be 15% of the serious patients present 14 days back.
- Amongst active cases, 2.37% are serious, 1.82% need oxygen, and 0.41% need ventilator support.
DENSITY: India: In states with average population density of 1185/sq km, the average number of cases were 2048. On the contrary, in states with population density of 909/sq km, the number of cases were 56. When Chandigarh and Pondicherry were taken out from this group, the Average Density of other states were 217 and the average number of cases were 35. [HCFI]
COVID Sutra: COVID-19 pandemic is due to SARS 2 Beta-coronavirus (different from SARS 1 where spread was only in serious cases); with over eleven virus sequences floating; Causes Mild or Atypical Illness in 82%, Moderate to Severe Illness in 15%, Critical Illness in 3% and Death 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 to Pneumonia 9 days, Mean Time to Death 14 days, Mean Time to CT changes 4 Days, Reproductive Number R0 1.5 to 3 (Flu 1.2 and SARS 2), Epidemic Doubling Time 7.5 days; Origin Possibly from Bats (Mammal); Spreads via Human to Human Transmission via Large and Small Droplets and Surface to Human Transmission via Viruses on Surfaces for up to three days. Enters through MM of eyes, nose or mouth and the spike protein gets attached to the ACE2 receptors. ACE2 receptors make a great target because they are found in organs throughout our bodies (heart muscle, CNS, kidneys, blood vessels, liver). Once the virus enters, 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
- Masking is THE prevention
- RT PCR cT is THE test for diagnosis
- Zinc is THE Vitamin
- Day 5 is THE day in COVID phase for mortality prevention
- Day 90 is THE day after which the word COVID ends
- Home Isolation is THE modality of Treatment
- 12 years is THE age when the mortality starts
- CRP is THE lab test for seriousness
- Loss of Smell is THE symptom equal to RT PCR test
- 15 minutes is THE time to get the infection.
Numbers to remember
- https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2770945: RDW at admission 14.5%
- Viral particles are seen in tears, stool, kidneys, liver, pancreas, heart, semen, peritoneal fluid, CSF.
- Thrombosis: University of Pennsylvania has reported that clots are seen in patients even on blood thinners.
- Other human beta-coronaviruses have immunity lasting only for one year with no IMMUNITY PASSPORT.
- In absence of interventions, prolonged or intermittent social distancing (till 2022-24) is the key.
- Due to low levels of cross immunity from other beta-coronaviruses against SARS-CoV-2, the virus may appear to fade away, only to show resurgence after a few years. Surveillance till 2024.
- During peak, trace and treat, and after the peak, trace and treat the close contacts.
- Increased spread: Close environment, crowded place with close physical contacts with no ventilation.
- Strategies: From community mitigation to individual containment; broader good over individual autonomy; perfect cannot be the enemy of the good; pandemics are fought on the grounds and not the hospitals. Treat the patient and not the test report; consider every surface and every asymptomatic person as virus carrier.
- HCW: Direct patient exposure time < 30 minutes; 7 days work and 7 days holidays.
- Italy: mortality reduced when they were short of ventilators.
- Hospital at HOME: CHF, mild pneumonia, exacerbations of asthma and COPD, cellulitis, and urinary tract infections.
- Great Imitator (protean manifestation).
- IgM can be false positive in pregnancy, immunological diseases; Pooled tests when seroprevalence is <2%.
- Early treatment, day 3-5, to reduce the viral load and prevent cytokine storm.
- Hypoxia: Low flow oxygen <6l/mt, titrated to high flow oxygen using non rebreathing mask, Venturi mask, HFNC and helmet CPAP, NIV in supine or prone position.
- Early intubation with prone ventilation only if progressive. Hypoxia (walking dead) have capillary problem and not alveoli.
Formulas and Predictions
- The goal is to save lives. Monitoring deaths is important, especially when testing is limited.
- Daily deaths are the best indicator of the progression of the pandemic, although there is generally a 17- to 21-day lag between infection and deaths.
- Deaths in symptomatic cases: Less than one percent (best of the care).
- Therefore, Deaths X 100 = expected number of symptomatic cases
- Some may count probable or presumptive COVID-19 deaths when cases are not confirmed with a positive test but on the basis of symptoms and medical history. In New York, 3,700 presumptive deaths were added in one day in April last year when testing was limited.
- Case fatality rate: Number of total deaths as on date/number of total RTPCR positive cases as on today
- Infection fatality rate: Number of total deaths as on date/number of total calculated cases as on today
- Number of reported deaths = Number of confirmed deaths x 2
- The University of Washingtons Institute for Health Metrics and Evaluation (IHME):
Is based on what is known about a disease and how peoples actions may affect that.
Forecasts are not fixed but change depending on public behavior. When people learn that new 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 their guard. IHME makes use of real-time infection data from Johns Hopkins Universitys Coronavirus Resource Center to represent disease transmission and estimate how many Americans will die. The researchers then estimate how many Americans are wearing masks or using social distancing, which can modulate the final model.
The rate of infection in a population is based on the "R0," or reproduction number. R0 represents the average number of people who will contract the infection from a single infected person, in a population thats never been witness to the disease before. If R0 is 3, it suggests that one case will create an average of three new cases. When that transmission rate of infection occurs at a specific time, its called an "effective R," or "Rt." R0 less than 1 means the epidemic is under control; and when its higher than 1, it is still spreading.
IHME found the "effective R over 1 in Oklahoma. In all other states the effective R was found to be less than 1.”
- CDC: Relies on positive tests results. CDCs report these as confirmed cases. The positivity rate suggests how tough or easy it is to find a case, which is an indicator of both the spread of COVID-19 and how widespread testing is. If the rate of positive tests is 20%, one doesn’t have to look hard to find a case, compared to 1%, which means that one has to do a lot of tests to get a positive one. The more COVID-19 spreads, the higher the positivity rate. A 60% positivity rate may suggest that testing is only being done in a nursing home during an outbreak or a hospital where the most apparent cases are and not the general population where cases may be milder.
- Marylands COVID-19 dashboard: It reports the daily positivity percentage (percentage of positive tests and total testing volume since March). While looking at testing, one wants to know how many tests were done historically with the ability to compare and understand if the number has increased or declined or is stable and the percentage that is positive. Maryland and Pennsylvania report a 7-day rolling average of the daily positivity percentages. The 7-day average rate better indicates a trend as compared to daily numbers.
- The testing numbers often fluctuate, depending on where testing is done and when the labs report test results. A sudden surge in testing numbers may point to a large number of tests done in a group setting such as a nursing home or prison on a single day. Laboratories and hospitals report test results on weekdays, so the numbers can decline on weekends.
- A major goal during the coronavirus epidemic has been to flatten the curve to maintain local hospital capacity. After expected COVID-19 surges, many hospitals limited surgeries and admissions to preserve their resources, including hospital beds, ventilators, and healthcare personnel.
- If hospital capacity reaches 80%, we may have to stop admitting patients to prevent the hospital from being overwhelmed.
- In order to plan for surges and increase capacity: It is required to know the number of people who tested positive and were admitted to the hospital with symptoms of COVID-19.
- Pennsylvanias COVID-19 dashboard: has a hospital preparedness page that shows the number of hospitalized COVID-19 patients and the number and percentage of available beds by unit, including intensive care, medical/surgical, and airborne isolation.
- Pennsylvania: Reports the number of ventilators COVID-19 patients and non-COVID-19 patients use every day.
- Illinois lists the recovery rate: In Illinois, the recovery rate of 95% has been calculated as recovered cases divided by recovered cases plus confirmed deaths. This indicates the quality of medical care and the severity of disease.
Some more numbers
- Cases will double after the average doubling time of the country at that time
- Cases expected in the community:
Get number of deaths occurring in a five-day period
Estimate the number of infections required to generate these deaths based on the country or area case fatality rate
Compare that to the number of new cases actually detected in the five-day period.
This can then give us an estimate of the total number of cases, confirmed and unconfirmed
- Lock down effect: Reduction in cases after average incubation period (5 days)
- Lock down effect in reduction in deaths: Reduction in number of deaths on day 14 (average time to death of that country)
- Requirement of ventilators on day 9: 1-3% of number of new cases detected
- Requirement of future oxygen on day 7: 10% of total cases detected today
- Number of people which can be managed at home care: 90% of number of cases today
- Requirement of ventilators: 1-3% of number of cases admitted 7-9 days back
- Requirement of oxygen beds today: 10% of total cases admitted seven days back
- Number of unreported or untested cases: Number of reported cases x 10-30 (depending on the country, New York 10, Delhi 23.8, Pakistan 30)
- Number of asymptomatic cases: For 6 symptomatic cases, 200 asymptomatic cases (CHINA); (1.78 M tests in Hong Kong, 32 asymptomatic cases, 10 symptomatic cases)
- Oxygen requirement on that day in the hospital at 6am: Number of cases detected to have hypoxia on six minutes walk test.
