Comparison of public health measures taken during Spanish flu and COVID-19 pandemics: A Narrative Review

The similarity of the consequences of COVID-19 reminded us of the destruction caused by the Spanish flu over a century ago and led us to find similarities in the way the two pandemics were handled. PRISMA Guideline was followed for a systematic search to identify eligible published articles. Information about the public health measures adopted during both the pandemics was taken from literature. It was found that there are parallels between the two pandemics in terms of general unpreparedness, attitudes of the community and government, and various policy issues. All the measures implemented in 2020 were the same as those implemented in 1918–1919, with the same trend, uncertainty, early relaxing, and rapid reversals. Even from a scientific standpoint, all the elements were already known. All the issues such as social isolation, intra-family spread, personal protective equipment, medicine types (quinine, aspirin, anti-inflammatories, etc.), immunization requirements, and so on had already been addressed. No doubt, we do have technology today at our disposal for managing the spread of the disease and even spread awareness among people much easily. We also have taken many steps forward in the world of globalization, which make the progression and spread of the pandemic very fast as well. Both factors tend to counter each other and hence make timely public health intervention as important (if not more) today as it was yesterday. When possible, approaches and goals should be found on scientific facts and include ethical input. Finally, we must take careful notice of past local and national lessons to avoid repeating the mistakes done in the past. The development of a strategy ahead of time that includes all levels of government health infrastructure and outlines clear lines of duties and functions is critical. The main objective of this article was to compare the public health measures undertaken during the pandemic of Spanish Flu and the pandemic of COVID-19, and assess the similarities and differences in the public health measures taken during these pandemics. The correlation of the public health measures and the outcomes was assessed and the implication of this article was to be pandemic-ready in the future.
