18 months of the COVID pandemic in 7 charts

A yr and a half in what theWorld Health Organization officially declared a pandemicon March 11, 2020, to say Individuals are exhausted is an understatement.

I’m aepidemiologistand an internationally acknowledgedscience communicator, and I typically discovered myself working between COVID-19 conferences asking “how did we get right here?”

Determining the ‘how’ is important to arrange for the longer term. In my effort to know the previous 18 months, I’ve discovered it useful to categorize the US pandemic journey to date into 5 levels: Scramble, Study, Reply, Check, and Hope.

Scramble: what’s occurring?

In early 2020, SARS-CoV-2, the virus that causes COVID-19, hit the US. The primary documented case was a traveler who landed in Seattle from Wuhan, ChinaJanuary 15. Solely later did public well being officers uncover that SARS-CoV-2 already existedspread across the community.

It wasn’t till March that Individuals have been compelled to take the pandemic critically, when states started to implementhome orders. Whereas residents struggled to search out outDay-care,working from homeandImmunology 101, epidemiologists started to reply.

However maybe a greater phrase is ‘scramble’. The US lacked the general public well being infrastructure to reply successfully. ANchronically underfundedandpoliticized public health systemhampered the nation’s real-time response.


Epidemiologists have been scrambling, left to…rely on volunteersto report public well being knowledge on the nationwide degree as a result of thereno centralized public health data systemwithin the US, public well being officers struggled to implement security suggestions and make contact with tracing due to:limited resources. Information scientists, like these atJohns Hopkins University, struggled to share accessible knowledge for resolution making. Scientists clambered toDeveloping COVID-19 tests. And everybody was scrambling to search out outhow to communicatethe evolving risk of the virus to American lives. From the beginning, the seeds have been sown for a reactive, somewhat than proactive, strategy.

Study: Are We Doing One thing Proper?

As soon as the northeast began to getunder controlJune 2020 was fairly quiet throughout the nation. Is that this accomplished? Possibly the declinebecause of the weather? Folks began to chill out.

Then July struck. In a month’s time, fallen within the Southwere so highas that they had been within the northeast months earlier than. The West additionally started to maneuver. The whack-a-mole recreation began as a result of there was nonetheless no coordinated, nationwide response.

Well being departments have beenexpand capacityfor testing, monitoring and monitoring. Numerous multidisciplinary, tutorial groups shaped to know COVID-19 fromvirology at the microscopic levelall the best way tosocial implications at population level.

That is when revealed, peer-reviewed knowledge on COVID-19 is available in. Scopus listed scientific literature database in lower than 5 monthsmore than 12,000publications. Researchers started to findlong COVID-19 symptomsand devising efficient protecting measures reminiscent of:social distancing and wearing a mask. Researchers additionally discovered extra aboutsuper spreader eventsand the way COVID-19 istransmitted by air– though this was not formally acknowledged by theWHOor theCenter for Disease Control and Preventiontill a few yr later.

Whereas thestream of evidencesupplied scientists and clinicians with essential info, awave of withdrawalspulling papers with misguided or unreliable knowledge began appearing. This, coupled with a scarcity ofaccurate scientific communicationfrom neutral sources, fed bysimultaneous infodemic– an epidemic of misinformation and public well being threats that researchers, social media firms and public well being officers are nonetheless studying to establish, mitigate and deal with.

Reply: Come on, virus!

Then got here winter, which turned out to be an ideal storm ofpandemic fatigueand vacation journey. This resulted in our largest pandemic wave thus far.More than 3,000 people died a daywithin the U.S

Happily, assist was on the best way: vaccines. And never simply fairly good vaccines — vaccines that blew efficacy out of the water. The Pfizer-BioNTech vaccine turned out to be aefficacy of 95%, considerably above thethreshold target of 50%. Because ofmore than 500,000scientific trial volunteers,decades of mRNA research, an estimatedUS$39.5 billionand fast-moving scientists, the vaccines got here inrecord time. And, whereas thethe roll-out of the vaccine was difficult,more than 260 milliondoses have been administered within the US in Might 2021

Nevertheless, with vaccines got here new challenges: a brand new battle in opposition to disinformation (no,mRNA does not change your DNA) and a battle to knowbreakthrough infections.

In the meantime,new COVID-19 variantsarrived on web site.Suboptimal Genomic Surveillancemade itdifficult to identify where and which variantsunfold. The race between vaccination and the unfold of variants had begun. The battle was removed from over.

Check: We’re drained

The early summer season of 2021 was blissful for Individuals. The US reached aall-time pandemic low in terms of COVID-19 cases. Individuals who had been vaccinated have been informed they maytake off their masks, whereas some unvaccinated folks took this carte blanche. Extra Individuals begantraveling againand again topersonal work.

However then the delta variant knocked on the door. appreciablemore transferableandstrictthan the unique pressure of the coronavirus, first created atsunami of fallen in the southwhich then unfold to all corners of the US.

Sadly,pandemic fatiguehas turn out to be established. And the pandemic is pushing the US response to its limits. It assessments the quantity of straincan withstand vaccines. It’s testinghealthcare capacity. It’s testing theresilience of public health and health professionals. It assessments scientists’ potential to speak successfullyever-evolving research results. And it places the general public’s persistence to the check whenpediatric vaccines undergoing clinical trials.

Hope: this may finish

Everyepidemic curve coming down. And this one too. However even after it goes down, the pandemic is much from over.

There’s nonethelesstrauma that needs to be addressed. Households have been robbed ofgood funerals and goodbyes.Friendships were torn apartpolitically charged disinformation and disinformation. Hundreds of thousands of individualslost their jobs. Andfrontline workersare nonetheless out of order. A survey of public well being professionals within the US discovered that:more than halfreported signs of at the least one psychological sickness from March to April 2021.

The US as a nation will even have to have interaction in self-reflection. To successfully deal with the following infectious illness disaster, the US might want to create centralized public well being programs and develop genomic surveillance, hospital networks, and testing capabilities. Scientists must renew the best way they convey science and analysis in an accessible means in order that the CDC can rebuild public belief. And by taking politics out of public well being, possibly science can infiltrate echo chambers as an alternative of…feed them.

Individuals ought to put together like thiswhen the next pandemic strikes, everybody will probably be prepared to have interaction in a proactive, efficient battle in opposition to a typical enemy: the virus.
