Between 1917 and 1920, mortality of the flu was &gt;20 million and of encephalitis lethargica approximately 1 million. For lessons to be learned from this pandemic, it makes sense to compare it with the COVID\u201019 pandemic, which occurred 100\u2009years later. Biomedical progress had enabled testing, vaccinations, and drug therapies accompanied by public health measures such as social distancing, contact tracing, wearing face masks, and frequent hand washing. From todays' perspective, these public health measures are time honored but not sufficiently proven effective, especially when applied in the context of a vaccination strategy. Also, the protective effects of lockdowns of schools, universities, and other institutions and the restrictions on travel and personal visits to hospitals or old\u2010age homes are not precisely known. Preparedness is still a demand for a future pandemic. Clinical trials should determine the comparative effectiveness of such public health measures, especially for their use as a combination strategy with vaccination and individual testing of asymptomatic individuals. It is important for neurologists to realize that during a pandemic the treatment possibilities for acute stroke and other neurological emergencies are reduced, which has previously led to an increase of mortality and suffering. To increase preparedness for a future pandemic, neurologists play an important role, as the case load of acute and chronic neurological patients will be higher as well as the needs for rehabilitation. Finally, new chronic forms of postviral disease will likely be added, as was the case for postencephalitic parkinsonism a century ago and now has occurred as long COVID.<\/jats:p>","DOI":"10.1111\/ene.16312","type":"journal-article","created":{"date-parts":[[2024,5,15]],"date-time":"2024-05-15T04:42:50Z","timestamp":1715748170000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["\u201cSpanish flu,\u201d encephalitis lethargica, and COVID\u201019: Progress made, lessons learned, and directions for future research"],"prefix":"10.1111","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8363-4962","authenticated-orcid":false,"given":"Michael","family":"Brainin","sequence":"first","affiliation":[{"name":"Department for Clinical Neurosciences and Preventive Medicine Danube University Krems  Krems Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1755-7943","authenticated-orcid":false,"given":"Yvonne","family":"Teuschl","sequence":"additional","affiliation":[{"name":"Department for Clinical Neurosciences and Preventive Medicine Danube University Krems  Krems Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2948-4187","authenticated-orcid":false,"given":"Ellen","family":"Gelpi","sequence":"additional","affiliation":[{"name":"Division of Neuropathology and Neurochemistry, Department of Neurology Medical University of Vienna  Vienna Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,5,14]]},"reference":[{"key":"e_1_2_8_2_1","volume-title":"Drawing Light from the Pandemic","author":"McKee M","year":"2021"},{"key":"e_1_2_8_3_1","volume-title":"The Great Influenza","author":"Barry John M","year":"2005"},{"key":"e_1_2_8_4_1","unstructured":"Centers for Disease Control and Prevention.https:\/\/archive.cdc.gov\/www_cdc_gov\/flu\/pandemic\u2010resources\/1918\u2010pandemic\u2010h1n1.html#:~:text=The%20number%20of%20deaths%20was occurring%20in%20the%20United%20States.&text=Read%20about%20the%201918%20influenza and%2065%20years%20and%20older.
