Was Covid real or basically just the cold or flu

COVID-19 was a real disease, distinct from the common cold and influenza, with a severity that varied enormously by age and health status.

The evidence from the first year of the pandemic is clear on this. A study adapting the Moving Epidemic Method to US all-cause mortality data found that for adults aged 18-49, there were 29 consecutive weeks of "very high severity" mortality in 2020, a pattern never seen with flu [4]. Nationally, all ages combined, there were 9 weeks of very high severity mortality [4]. In a German community that experienced a superspreading event, total deaths in 2020 were similar to 2015 and 2018, but one-third of people who died with confirmed SARS-CoV-2 infection had a non-COVID-19 cause of death, meaning the virus was not the sole driver of every death counted [2]. In Iran, a reconstruction using excess mortality estimated that by October 2021, cumulative excess deaths were 259,641 (95% CI: 230,493-288,790), nearly double the 125,000 officially reported COVID-19 deaths, showing massive undercounting [1].

The claim that it was "just the flu" collapses when you look at the numbers. A Dutch primary-care study found that a GP diagnosis of COVID-19 was associated with a 10.9-fold increase in all-cause mortality (HR 10.90; 95% CI 8.51-13.96) compared to those without it [3]. That is an order of magnitude higher than what seasonal influenza typically produces in similar populations. The virus also caused distinct immune dysregulation, including lymphopenia and elevated neutrophil-to-lymphocyte ratios that correlated with disease severity, a pattern not typical of the common cold [6]. A case report documented persistent psychotic symptoms following infection, with elevated inflammatory markers like TNF-α, suggesting the virus could trigger neuropsychiatric sequelae through immune mechanisms [5].

The common cold is caused by rhinoviruses and other mild coronaviruses. Influenza kills, but in a typical season it does not produce 29 consecutive weeks of very high severity mortality in working-age adults. COVID-19 did. The evidence shows it was a novel pathogen with a unique combination of transmissibility, immune evasion, and severe outcomes, especially for older adults and those with underlying conditions.

My call: COVID-19 was a real and distinct disease, far more severe than the common cold and, in its early waves, substantially more lethal than seasonal influenza for adults. Confidence: high.
