CMAAO: In susceptible high-risk (pro-inflammatory and/or pro-coagulative) individuals, reactogenic vaccines can trigger transient thrombo-inflammation lasting first few (up to four) days.
COVID Vaccine: non-replicative, non-repetitive dose, spike gene mRNA/spike gene DNA to mRNA/whole killed virus, reactogenic vaccine

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 -
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:
Once a large population receives vaccination, immune pressure would likely facilitate and speed up the emergence of such variants by selecting for escape mutants.

Facts
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.

Prediction Metrics
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.”
Infrastructure Capacity
Some more numbers
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
