Mission: To provide a one-stop Web resource page with factual information about the COVID-19 Pandemic

According to PEW , social media users share COVID-19 information mostly from news sources (74%) and very little from health and science resources (1%). This could mean that people do not know where to look for credible science-based information about COVID-19.

On June 18, 2020, JAMA reported "Coronavirus disease 2019-related knowledge and behaviors were associated with race/ethnicity, sex, and age. African American participants, men, and people younger than 55 years were less likely to know how the disease is spread, were less likely to know the symptoms of coronavirus disease 2019, and left the home more often."

Furthermore, the prevalence of Coronavirus myths addressed by the World Health Organization indicates that there is much disinformation and misinformation on the Internet about the SARS-CoV-2 virus.

Therefore, I have decided to create this resource page for those interested in learning more about the pandemic. It is my hope, as Master Certified Health Education Specialist (MCHES®), that you will be able get the credible information you need here to make the decisions you have to make to deal with the pandemic in your life. I am dedicated to keeping this page updated with vetted sources, and welcome your feedback. (July 6, 2020)

The dangers of pandemic revisionism (Dr. Katelyn Jetelina)

Fueling the dismantling of our public health infrastructure is pandemic revisionism-the rewriting of history from the comfortable vantage point of 2025, where we now enjoy the benefits of immunity, scientific knowledge, and hindsight.

Let's be crystal clear: In the first year of the pandemic, we faced a crisis with literally no vaccine, no treatment, terrible diagnostics, no surveillance system, and no federal plan. Outbreaks were widespread, hospitals were overwhelmed, and people were dying. This is not hyperbole-this was our reality.

We must be able to hold two truths: 1. Mistakes were made. 2. Public health demonstrated remarkable resilience. Revisionist narratives often erase the second truth.

CDC has three numbers you should consider to know if you've been exposed to the coronavirus: If you've been within six feet of an infected person for at least 15 minutes starting from 48 hours before the infected person began feeling sick, you are considered to have been in close contact with the virus.

Vipin M. Vashishtha @vipintukur The main entry point for SARS-CoV-2 into the body is ACE2 receptor. Researchers have now identified another receptor, called RAGE, present on the surface of monocytes, which can bind to SARS2 & allow it to enter cells, altering their function & leading to a worse prognosis. (https://twitter.com/vipintukur/status/1730449882379685935)

RAGE (receptor for advanced glycation endproducts) activation in monocytes was already known to correlate with more severe inflammatory outcomes, diabetes and obesity, but had never been observed in the context of viral infection. (https://twitter.com/vipintukur/status/1730450640663728347)

Graphic source: Wang-Cell-PhylogeneticTree.jpg

SARS-CoV-2, the coronavirus that causes the disease COVID-19, is a big viral family with many variants. Just like with a human family tree, the distance between two variants shows roughly how related they are. This illustration is inspired by the SARS-CoV-2 phylogenetic tree generated by Emma Hodcroft of Nextstrain.org and the University of Bern. Kat Hubbs for NPR

XFL Variant
Graphic source: https://x.com/Mike_Honey_/status/1916885109950841038

Mike Honey @Mike_Honey_
Earlier this month the XFL variant was defined, setting a new benchmark in SARS-CoV-2 evolution: a "quadruple-recombinant", meaning it's evolution includes 3 recombinant ancestors. It’s a stark example of how we are giving this virus every opportunity to evolve

NB.1.8.1 Variant AKA Nimbus (January 22, 2025)

NB1.8.1
Graphic source: https://x.com/TRyanGregory/status/1927371947999957310/photo/1

NB.1.8.1 has a tangled family tree. It is a hybrid virus, built from a process called recombination, where several viruses – all versions of the Omicron COVID variant -infect the same cell and swap genetic material. It is descended from XDV -- a hybrid of JN.1 and XDE (a hybrid of GW.5.1 and FL.13.4).These events have equipped “Nimbus” with seven new mutations in its spike protein, which is the part of the virus that attaches to human cells, plus a further 20 changes elsewhere.

XFG Variant AKA Stratus (Southeast Asia, January, 2025)

Al-Aly - Long Covid
Graphic source: https://medicine.wustl.edu/news/risk-of-long-covid-declined-over-course-of-pandemic/

The risk of developing long COVID has decreased significantly over the course of the COVID-19 pandemic.

Researchers attributed about 70% of the risk reduction to vaccination against COVID-19 and 30% to changes over time, including the SARS-CoV-2 virus’s evolving characteristics and improved detection and management of COVID-19.

In more than 30 high-profile studies, Al-Aly has detailed the virus’s indiscriminate, long-term health impacts across nearly all organ systems affecting the heart, brain, kidneys and gastrointestinal (GI) tract.

“Long COVID is not over. We cannot let our guard down. This includes getting annual COVID vaccinations, because they are the key to suppressing long COVID risk. If we abandon vaccinations, the risk is likely to increase.”

Unsurprisingly, the rate of long COVID was the highest among those with the original strain, Al-Aly said, with 10.4% of those who had infections that developed into long COVID. That declined to 9.5% among those in the unvaccinated groups during the delta era and 7.7% during omicron.

Among the vaccinated, the rate of long COVID during delta was 5.3% and 3.5% during omicron. “You can see a clear and significant difference in risk during the delta and omicron eras between the vaccinated and unvaccinated,” said Al-Aly, “So, if people think COVID is no big deal and decide to forgo vaccinations, they’re essentially doubling their risk of developing long COVID.”

"Experts have warned that the coronavirus — a respiratory pathogen — most likely capitalizes on the scarred lungs of smokers and vapers. Doctors and researchers are now starting to pinpoint the ways in which smoking and vaping seem to enhance the virus's ability to spread from person to person, infiltrate the lungs and spark some of Covid-19's worst symptoms." https://www.nytimes.com/2020/09/04/health/covid-vaping-smoking.html

    COVID-19 Incubation Period


    Nature: Estimated that the incubation period for COVID-19 before the onset of symptoms was 5.2 days. Viral loads for COVID-19 were highest shortly after the onset of symptoms and then gradually decreased toward the detection limit by day 21. Sex, age, and disease severity did not substantially affect these findings.

    The authors estimated that infectiousness of COVID-19 began 2.3 days before the onset of symptoms and peaked at 0.7 days after symptom onset. They further estimated that up to 44% of cases of COVID-19 could be a result of viral transmission before the onset of symptoms. Source: https://www.medscape.org/viewarticle/932932 (6/2020)

Some share of the neighbors of a node which tests positive are traced and tested themselves." Reich et al. 2020

    This graph shows how an epidemic might spread across a network over time. Blue dots are susceptible individuals, while red dots are infected people. Two dots are connected by a line if they are in contact with each other, and the more contacts a person has, the bigger their dot is on the network. Author provided

    Infected people are red nodes, and susceptible people are blue. The large node in the middle of the diagram is a super-spreader, a person who connects with many others, and thus has more potential to spread the disease.

    Air (Airborne)Transmission


    From Pri-Med April 5, 2025.
    MIT’s Dr. Lydia Bourouiba blew our knowledge wide open. Bourouiba, unbothered by the nickname “The Sneeze Lady,” was the first to use high-speed video to capture this “violent expiratory event.” She documented “the explosive aftermath in gross detail” with the reverence of someone describing a Van Gogh sky. Key revelations:
    Sneeze droplets can spray up to eight meters and linger—“in midair, mind you”—for ten minutes, debunking the one-to-two–meter myth.
    Fluid exits the mouth in sheets, then shreds into rings, then filaments, before finally splintering into droplets—a more dynamic path than once assumed.
    Larger droplets sink fast while smaller ones hover ominously.
    Environmental factors, eg, humidity and temperature, influence droplet formation and travel.
