Lengthy Flu Is a Well being Threat, New Research Says

Lengthy Flu Is a Well being Threat, New Research Says


Statistically, there’s an excellent probability you already know anyone who has skilled Lengthy COVID, the title for power signs together with fatigue, mind fog, and ache following a case of COVID-19. About 14% of U.S. adults report having had Lengthy COVID sooner or later, based on federal knowledge.

However many individuals don’t notice that different viruses, even quite common ones, can set off equally long-lasting and debilitating signs. A examine printed Dec. 14 in The Lancet Infectious Ailments focuses on the danger of creating “Lengthy flu” after a extreme case of influenza.

“We discovered from COVID-19 that infections which might be initially thought to trigger solely acute diseases could cause power illness,” says co-author Dr. Ziyad Al-Aly, chief of analysis and improvement on the Veterans Affairs St. Louis Well being Care System and a scientific epidemiologist at Washington College in St. Louis. That is true of influenza as effectively, the brand new analysis exhibits.

Al-Aly and his colleagues used data from the U.S. Division of Veterans Affairs to check the long-term well being outcomes of about 11,000 folks hospitalized with influenza from 2015 to 2019 with these of about 81,000 folks hospitalized with COVID-19 from 2020 to 2022. The researchers tracked how many individuals went on to develop any of 94 well being dangers related to the 2 viruses within the 12 months and a half after they had been hospitalized.

Relative to influenza survivors, individuals who’d had COVID-19 had been at elevated threat of 64 of the recognized issues, together with fatigue, mental-health issues, and pulmonary, gastrointestinal, and coronary heart problem. They had been additionally extra prone to die through the examine interval, in line with different analysis evaluating the long-term outcomes of the 2 diseases.

Influenza survivors, in the meantime, had been at elevated threat of solely six well being issues, most of them associated to the respiratory and cardiovascular techniques.

“COVID continues to be extra severe than the flu,” Al-Aly says, noting that it impacts quite a few organ techniques whereas influenza is usually a respiratory sickness. However long-term well being issues had been frequent in each teams through the 18 months of follow-up. The researchers recorded about 615 well being points per 100 folks within the COVID-19 group, in comparison with about 537 per 100 folks within the influenza group. These numbers mirror the truth that some folks expertise quite a few power signs after an an infection, Al-Aly says.

It’s essential to notice that the folks included within the examine had been all hospitalized, which means they had been very sick through the acute phases of their diseases. The examine inhabitants was additionally overwhelmingly male and older, with a mean participant age of 70. Older adults are identified to be susceptible to the worst results of each COVID-19 and the flu. Due to this fact, the outcomes could not translate to the whole inhabitants.

That stated, earlier analysis exhibits that even milder diseases can result in long-lasting well being points. Influenza, in addition to different frequent viruses like Epstein-Barr (which causes mononucleosis), have lengthy been thought to set off myalgic encephalomyelitis/power fatigue syndrome, a post-infectious sickness that shares many signs with Lengthy COVID.

Newer analysis additionally underscores the potential results of even routine diseases. In a examine printed in October, researchers tracked individuals who had gotten sick with considered one of quite a lot of respiratory ailments, together with COVID-19, the flu, and the frequent chilly, and located that lingering signs popped up in every group. Equally, in a single 2022 examine of individuals with numerous respiratory ailments, most of whom weren’t hospitalized, about half of individuals sick with one thing apart from COVID-19 reported ongoing points three months later. A 2021 examine each hospitalized and non-hospitalized sufferers additionally discovered that about 40% of individuals with influenza skilled not less than one symptom generally related to Lengthy COVID within the six months after their diseases.

Taken collectively, Al-Aly says, these findings recommend that we have to begin pondering of viruses otherwise. “Earlier than the pandemic, I trivialized infections. [I thought] you get sick for a day or two or three, and then you definately bounce again, and it’s throughout,” Al-Aly says. However as a rising variety of research present that’s not all the time the case, he has concluded that “infections deserve respect.”

Meaning doing no matter potential to keep away from catching and spreading them, he says, together with by sporting a masks during times of heavy transmission, getting all beneficial vaccines, and staying dwelling if you really feel unwell.
