Return of the Flu: Flurona, a Co-occurring Infection that is NOT

The beginning of 2022 brought about an ominous rise in COVID-19 cases as the Omicron variant began to ravage the United States in earnest, with the Centers of Disease Control and Prevention reporting about 1.3 million new cases on January 10th. While this report is inclusive of a weekend backlog, representing the majority of states’ reporting for 2 days, rather than 1, this kind of report for any respiratory transmission is truly startling. In the background, another virus with a respiratory transmission mode, influenza, had been crushed to near non-existence during the 2020-2021 season, according to the CDC’s FluView surveillance report. Indeed, on the surface, what appears to stop COVID transmission, stops flu transmission even better. But with the relaxing of mitigation measures, “pandemic fatigue”, and society eagerly looking to move on, the flu has begun to mount its seasonal return.

In comes the frightening shadow of “flurona”! Social media sites buzzed with the dire warning experts had given in 2020: a ghastly winter with two very dangerous, highly communicable diseases ripping through the nation. The difference in late 2021 and early 2022, compared to the year before, is obvious: wide access to COVID-19 vaccinations (in the United States, at least) and a continuation of annual influenza vaccination availability. This co-occurring infection, however, isn’t new. Indeed, the United States likely experienced some combined infections during the early days of the COVID pandemic in 2020, prior to the wide availability of diagnostic COVID tests, and again in the 2020-2021 flu season. While the instances may have been relatively rare due to the decrease in influenza transmission, the situation was not entirely unknown. It was, after all, the CDC’s FluView surveillance that shaped our initial tracking of community transmission of SARS-CoV-2 (the virus that causes COVID-19); the surveillance program tracks weekly reports from health care providers and local and state health departments of influenza like illness (ILI) incidence and the results of flu screenings in order to ascertain key metrics of public health response.

Let’s pause for a moment to acknowledge just how remarkable the 2020-2021 flu season was. A key measure in tracking influenza is pediatric mortality. In both the 2018-2019 and 2019-2020 flu seasons, the CDC reported 144 and 199, respectively, pediatric deaths attributed to the flu. In the 2020-2021 season, the CDC reported only 1 pediatric flu death (CDC data application). The total national percent positivity (or number of reactive tests relative to total tests administered) for influenza during the 2020-2021 flu season never crested the national baseline for the season of 2.6% positivity compared to only being about half way through the season this year and already having crested the national baseline (2.5%) for the last 5 weeks. In the 2019-2020 flu season, percent positivity for the flu crested the national baseline (2.4%) for 22 weeks.

We shouldn’t be dismissive of influenza. It is still a serious illness that hospitalizes many, especially vulnerable populations. National vaccination programs have done a great deal to help curb the potentially deadly impacts of influenza, though, schools have been known to be shut down due to flu outbreaks, including in early 2019. The idea of selective mitigation efforts coming and going in order to address outbreaks, isn’t new.

So here we are with Flurona – an incidence which may well have been happening this whole time, but because we don’t specifically track this particular co-occurring infection, we can’t say for sure. While there’s limited data on what to expect with a co-occurring flu and COVID infection, that data is a tad concerning; mortality did not necessarily increase but the symptomology of this type of situation did require frequent use of mechanical ventilation.

The catchy combined name of these viruses went…well…viral, even if only for a short period of time. As the project director for CANN’s HIV-HCV Coinfection Watch, the idea of a co-occurring viral infection didn’t surprise me. And it probably doesn’t surprise many of our readers here. The fact that it did surprise many members of the public, even after Dr. Anthony Fauci and other officials had previously mentioned the possibility, is indicative, inditing even, of how information is delivered and disseminated in today’s world. Numerous studies have been done on the amount of stress and anxiety people are experiencing in light of the COVID-19 pandemic. The CDC has also dedicated a page to “Coping with [pandemic-related] Stress” and many states have adopted mental health helplines for residents to dial into. The relationship between the public, experts, and news media is deeply damaged by practices of all parties – a busy public less interested in reading longer, more detail articles, a news media competing for clicks and attention in order to fund their outlets, and experts competing for space and importance because of outlet bias and lack of vetting have all harmed our ability to cohesively respond to the COVID-19 pandemic.

I’m not usually one to say “can’t we all just get along”, my job, in fact, is often about digging deep into spaces of disagreement or interest conflict and hammering out mutually beneficial concessions. This place we’ve found ourselves in as a society, where we’re all operating out of scarcity and competition at all costs is ultimately how we all “lose”; be it this pandemic, the next, or even in combatting long standing ills already needing address. Patient advocates and public health officials having to divert time and resources to educate patients and the public when a panic-inducing headline aimed at derailing the reader’s tasks is, in fact, derailing to multitudes of efforts to better the world around us if by sheer inability to focus on our tasks at hand.

If you’re struggling with coping with stress of the pandemic, flurona headlines, COVID variant headlines, any headlines, please, take a moment to review the National Alliance on Mental Illness (NAMI) COVID Resource and Information guide, or give them a shout on their hotline to be directed to area specific resources by calling 800-950-6264 or by clicking “chat with us” at the bottom of this page.

There’s little in this world that can’t be made a tiny bit more manageable with a snack, a nap, or a hug. Check those boxes, take a deep breath, and know you’re not alone.
