1. Understanding the 1918 Spanish Flu
The 1918 Spanish flu, caused by an H1N1 influenza A virus, swept the globe from 1918 to 1920. It’s believed to have originated from avian sources. This devastating pandemic unfolded in four distinct waves, each leaving a significant mark on the world.
- First Wave: Mid-February to early June 1918
- Second Wave: Early August to early December 1918
- Third Wave: Early December 1918 to late April 1919
- Fourth Wave: Early December 1919 to late April 1920
The Spanish flu infected approximately 500 million people, representing about one-third of the world’s population at the time. The pandemic resulted in an estimated 50 million deaths worldwide, with 675,000 deaths occurring in the United States alone. The first public announcement of the epidemic appeared in Madrid’s ABC newspaper on May 22, 1918, leading to its moniker, the “Spanish flu.” Despite the name, the virus’s true origin remains uncertain, with many epidemiologists and virologists suspecting it originated in the USA or France.
2. The COVID-19 Pandemic: A Modern Crisis
The COVID-19 pandemic, caused by the SARS-CoV-2 virus, emerged in Wuhan, China, in late 2019 and quickly spread worldwide. As of late 2023, it has infected hundreds of millions of people and caused millions of deaths, triggering unprecedented global health, social, and economic challenges.
3. Key Differences in Affected Populations
One of the most striking differences between the 1918 Spanish flu and COVID-19 lies in the demographics of those most severely affected.
- 1918 Spanish Flu: Disproportionately affected young adults aged 25–40.
- COVID-19: Primarily impacts older adults, particularly those over 65 with comorbidities.
During the Spanish flu, the mortality rate for younger individuals (25–40) rose to 8%–10%, compared to an overall mortality rate of 2.5%. In contrast, COVID-19 has a mortality rate of around 0.2% for the same age group (25–40), while the overall mortality rate is around 2.4%. Forty percent of deaths from the 1918 flu were among those aged 25–40, while only 3.9% of COVID-19 deaths in the USA were in the 18–44 age range.
4. Contrasting Mechanisms of Death
The way these two diseases cause death also differs significantly.
- 1918 Spanish Flu: Patients often died from secondary bacterial pneumonia.
- COVID-19: Death is commonly caused by an overactive immune response leading to multiple organ failure. Acute Respiratory Distress Syndrome (ARDS) can develop in both cases. ARDS as a complication from the Spanish flu had a 100% fatality rate, compared to a 53.4% mortality rate as a complication from COVID-19.
5. Global Spread and Impact
The global reach of the two pandemics also presented notable contrasts.
- 1918 Spanish Flu: While devastating, some countries were spared.
- COVID-19: Spread to nearly every country, with only a few Pacific Islands remaining COVID-19-free.
By November 16, 2020, the USA alone had over 11 million COVID-19 cases, nearly a 40% increase from the previous month.
6. Economic Consequences
Both pandemics have had significant economic repercussions, although precise comparisons are challenging due to differing data availability.
- COVID-19: Projected economic impact on the US economy is estimated at a $5.76–$6.17 trillion decrease in gross domestic product (GDP).
- 1918 Spanish Flu: Economic data is scarce, but Mexico suffered an estimated $9 billion loss.
7. Diagnostic and Treatment Advancements
The speed and effectiveness of diagnostic and treatment efforts differed substantially between the two pandemics.
- COVID-19: Delays in developing and confirming diagnostic tests. Development and investigation of treatments such as antivirals (e.g., remdesivir), antibody therapies, and interleukin-33 blockers. Rapid development of vaccines.
- 1918 Spanish Flu: Limited progress in pneumonia treatment; bleeding was used as a treatment. In 1917, a vaccine to prevent pneumonia caused by types I, II, and III pneumococci was developed and tested, showing some success in preventing pneumonia among vaccinated troops.
Isolation and quarantine were the primary containment methods in both pandemics, given the initial lack of vaccines and effective treatments.
8. Duration and Origins
Controversy surrounds the origins of both viruses, and both pandemics involved multiple waves of infection.
- 1918 Spanish Flu: Lasted approximately 25 months. Possible origins in Spain, France, or the USA, with no definitive evidence. Four waves from February 1918 to April 1920.
- COVID-19: Originated in Wuhan, China, in December 2019. Debate over whether it originated in a wet market or the Wuhan Institute of Virology. DNA sequencing can predict whether infected individuals will be symptomatic or asymptomatic.
9. Comparing Mortality Rates
Mortality rates provide essential context for understanding the severity of both pandemics. The following table presents a concise comparison:

18. Synthetic Biology: A Future Tool
Looking ahead, synthetic biology offers promising tools for diagnosing and treating future pandemics. With synthetic biology, diagnosis could be done using full sequencing of COVID-19 strains, which would also reveal the number of strains. Additionally, obtaining data on patient genotypes would determine its impact on viral expression. Furthermore, vaccines developed with synthetic biology and then made with nanotechnology can be made in unlimited quantities compared with present methods of vaccine production, which use fertilised chicken eggs. Synthetic vaccines can be made to each strain with a unique sensor on each monoclonal antibody, which would indicate the presence of a particular strain, allowing efficient and timely vaccinations in each population.
19. Unraveling the Viral Mystery
By studying each base of its positive-sense messenger RNA and determining its individual function, we can then predict patient prognosis and be better prepared to treat patients as they become ill. The prognosis of patients in the intensive care unit is currently poor, with high mortality rates and risk of permanent lung damage.
As we better understand the functional phenotypic expression of COVID-19, we can start to predict the expression of viral mRNA and begin treatment earlier. This is a race between using our most advanced synthetic biology of the 21st century against a 21st-century virus. We are 100 years away from 1918 and the tools that the scientists and clinicians had at their disposal in the last century. Let’s hope that we can win this battle against this virus. It is difficult to predict how long this battle will continue but with synthetic biology in conjunction with social distancing, we should achieve victory.
