There is a cautionary note from the 1918 flu that has resonance in 2020, and it could reinvigorate social-distancing and mask-wearing behavior among those people who are feeling the fatigue of disruption to their daily lives: “While 1918 was deadly, most that contracted the virus survived. But survival does not mean that individuals fully recovered.”
That’s according to a review of literature and studies on the 1918 flu by economists at Vanderbilt University in Nashville, Oberlin College in Oberlin, Ohio, and Carnegie Mellon University in Pittsburgh. “The evidence suggests that, in 1918, those that survived the initial infection faced an elevated mortality risk and some physiological conditions never fully healed.”
“The first lesson from 1918 is that the health effects were large and diffuse. We may never know the true mortality consequences of 1918 because of incomplete or inaccurate record keeping, issues that also undermine our ability to quantify the impact of COVID-19,” they wrote. “The range of lingering health effects for those that contract COVID-19 and survive remains to be seen.”
The 2020 coronavirus and 1918 influenza are two highly contagious respiratory diseases that spread around the world in months. For the 1918 flu, healthier, younger people were most at risk. In 2020, it’s older people with preexisting conditions. But even fit people have had problems long after they’ve developed the antibodies to the virus.
SARS-CoV-1 in 2003 may provide more clues to what some patients can expect in 2020. This two-year study in the journal Respirology of a selected population published in 2010 of SARS survivors “showed significant impairment” of diffusing capacity for carbon monoxide or lung function, exercise capacity and health status with a more significant adverse impact for health-care workers.
A review of cases published last March in the medical journal JAMA Cardiology concluded: “Coronavirus disease 2019 is associated with a high inflammatory burden that can induce vascular inflammation, myocarditis, and cardiac arrhythmias.” It added, “Cardiovascular risk factors and conditions should be judiciously controlled per evidence-based guidelines.”
COVID-19 may induce new cardiac issues and/or exacerbate underlying ones, the researchers said. “During most influenza epidemics, more patients die of cardiovascular causes than pneumonia-influenza causes. Given the high inflammatory burden of COVID-19, and based on early clinical reports, significant cardiovascular complications with COVID-19 infection are expected.”
