India predictions

  1. Death rate is deaths today vs number of cases today.
  2. Corrected death rate is deaths today vs number of cases 14 days back.
  3. For one symptomatic test positive case, there are 10-30 asymptomatic cases and 20 untested cases.
  4. Estimated number of deaths = Reported deaths x 2.
  5. Number of deaths today should be 15% of the serious patients present 14 days back.
  6. Undocumented cases for each documented case - 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% need ventilator support.

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

  1. Masking is THE prevention
  2. RT PCR Ct is THE test for diagnosis
  3. Zinc is THE Vitamin
  4. Day 5 is THE day in COVID phase for mortality prevention
  5. Day 90 is THE day after which the word COVID ends
  6. Home Isolation is THE modality of Treatment
  7. 12 years is THE age when the mortality starts
  8. CRP is THE lab test for seriousness
  9. Loss of Smell is THE symptom equal to RT PCR test
  10. 15 minutes is THE time to get the infection.

Numbers to remember

  1. https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2770945: RDW at admission 14.5%

Other Sutras

  1. Viral particles 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 even on blood thinners.
  3. Other human beta-coronaviruses have immunity lasting only for one year with no IMMUNITY PASSPORT.
  4. In absence of interventions, prolonged or intermittent social distancing (till 2022-24) is the key.
  5. 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.
  6. During peak, trace and treat, and after the peak, trace and treat the close contacts.
  7. Increased spread: Close environment, crowded place with close physical contacts with no ventilation.
  8. 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.
  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. Hospital at HOME: CHF, mild pneumonia, exacerbations of asthma and COPD, cellulitis, and urinary tract infections.
  12. Great Imitator (protean manifestation).
  13. IgM can be false positive in pregnancy, immunological diseases; Pooled tests (<5, 20 Kerala, 64 Singapore RT PCR) when seroprevalence is <2%.
  14. Early treatment, day 3-5, to reduce the viral load and prevent cytokine storm using hydroxychloroquine with azithromycin or ivermectin with doxycycline with IV remdesivir and IV single dose tocilizumab (IL-6 receptor inhibitor) if very high D-dimer and IL-6; convalescent plasma therapy (given early; donor 14 days symptoms free, between day 28-40, single donation can help 4 patients), Lopinavir-ritonavir and Favipiravir if very low CD 4 counts.
  15. 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.
  16. Early intubation 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. Monitoring deaths is important, especially when testing is limited.
  2. 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.
  3. Deaths in symptomatic cases: Less than one percent (best of the care).
  4. Therefore, Deaths X 100 = expected number of symptomatic cases
  5. Some may count "probable" or "presumptive" COVID-19 deaths when cases are not confirmed with a positive test but are based on symptoms and medical history. New York added 3,700 presumptive deaths in one day in April when testing was more limited.
  6. Case fatality rate: Number of total deaths as on date/number of total RTPCR positive cases as on today
  7. Infection fatality rate: Number of total deaths as on date/number of total calculated cases as on today
  8. Number of reported deaths: Number of confirmed deaths x 2

 

Prediction Metrics

  1. 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 is less than 1.”

  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.
  2. 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 comes back positive. Maryland and Pennsylvania report a 7-day rolling average of the daily positivity percentages. The 7-day average rate smooths out fluctuations during the week and is better indicates a trend as compared to daily numbers.
  3. 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.
  4. 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. [WebMD]

 Infrastructure Capacity

  1. If hospital capacity reaches 80%, we may have to stop admitting patients to prevent the hospital from being overwhelmed.
  2. 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.
  3. 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.
  4. Pennsylvania: Reports the number of ventilators COVID-19 patients and non-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. Cases will double after the average doubling time of the country at that time
  7. 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

  1. Lock down effect: Reduction in cases after average incubation period (5 days)
  2. Lock down effect in reduction in deaths: Reduction in number of deaths on day 14 (average time to death of that country)
  3. Requirement of ventilators on day 9: 1-3% of number of new cases detected
  4. Requirement of future oxygen on day 7: 10% of total cases detected today
  5. Number of people which can be managed at home care: 90% of number of cases today
  6. Requirement of ventilators: 1-3% of number of cases admitted 7-9 days back
  7. Requirement of oxygen beds today: 10% of total cases admitted seven days back
  8. 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)
  9. 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)
  10. Oxygen requirement on that day in the hospital at 6am: Number of cases detected to have hypoxia on six minutes walk test.
