Aim In view of the spread of the contagious coronavirus disease (COVID-19) globally, the present review focuses on the details of past pandemic diseases, along with comparisons and lessons learned. A general awareness of COVID-19 infection is addressed, and it is compared with the Spanish flu pandemic. Based on the successes, failures and lessons learned in the past, governmental efforts must be undertaken to empower citizens by providing accurate information and implementing post-COVID-19 precautions that need to be taken now to stop the spread and recurrence of the virus locally, and to restore health and economic normalcy. Methods A detailed literature survey of past pandemics is undertaken in order to extract the successes, failures and lessons learned from previous breakouts. The comparison of past pandemics will enable us to determine post-COVID-19 precautions that should be followed. Separate tables are prepared to highlight the lessons learned and measures to be taken. Both general precautions and preventive measures for pregnant women are compiled. Results The literature shows a continuous struggle of humans with disease outbreaks, with the most adverse impact of the Spanish flu killing 20-50 million people. Precautions need to be taken including social distancing, compulsory mask-wearing, avoiding public gatherings and washing hands regularly. The lessons from earlier pandemics show that they were equally devastating, and vaccines were not available at the time of outbreaks. Vaccines developed for polio, H1N1, measles, and other viral diseases have proven to save countless lives. Living with COVID-19 and evolving the work culture of protecting oneself and protecting others also has to be adopted. Conclusions COVID-19 has become an everyday topic of discussion throughout the world, indicating the increasing number of COVID-19 cases, deaths and recoveries. The lessons learned from past pandemics such as social distancing, wearing masks, avoiding public gatherings and adherence to guidelines, along with personal hygiene, are the key measures that must be taken in order to live with COVID-19. Precautions for the elderly and pregnant women advised by medical authorities are to be strictly adhered to. These will help in reducing COVID-19 cases and in turn will reduce the pressure on hospitals to serve those in need. India has learned lessons from the past and the present pandemic and will move towards growth through its self-reliance.

Background and Objectives: The diagnosis of acute coronary syndromes can be challenging inpatients admitted with the non-cardiac disease to the Intensive Care Unit (ICU). The study aimed todetermine the clinical profile of critically ill elderly patients developing myocardial injury who wereadmitted to ICU for non-cardiac diagnosis. Materials and Methods: The retrospective studysubjects are 130 patients admitted to the medical ICU. Within 24 hours of admission to ICU adetailed history, a 12 lead ECG, CK-MB, Cardiac troponin T was done and as required based on ECGfindings and development of clinical symptoms. Results: Our study showed that 35 out of 130patients developed acute myocardial injury. 13 out of 35 patients who had myocardial injury had afatal outcome. The prevalence of hypertension, diabetes mellitus, history of CVA, history of IHD andCOPD reached statistical significance (p<0.001) between the two groups of patients who developedmyocardial injury and who did not develop a myocardial injury. In patients with multiplecomorbidities, the presence of factors like hypoxia, hypotension and the use of vasopressorsincreases the risk of mortality. Conclusion: All elderly patients who are hospitalized with or withoutmultiple comorbidities with an acute form of stressors must be evaluated aggressively forprecipitants and adequately treated to prevent myocardial injury.
