Abstract
BackgroundThis study aimed to assess the impact of 15 days before, 15 days during, and 15 days after the lockdown on the trends in the prevalence and mortality in 27 countries during COVID-19 pandemic.MethodsTwenty-seven countries were randomly selected from the different continents. The information on the trends in the prevalence and mortality due to COVID-19 pandemic in 27 countries was obtained from World Health Organization and lockdown data were obtained from concerned countries and their ministries. The impact of lockdown for 15 days before, 15 days during, and 15 days after the lockdown on the prevalence and mortality due to the COVID-19 pandemic in 27 countries was analyzed.ResultsThe findings showed that 15 days after the lockdown there was a trend toward a decline, but no significant decline in the mean prevalence and mean mortality rate due to the COVID-19 pandemic compared to 15 days before, and 15 days during the lockdown in 27 countries. The mean growth factor for number of cases was 1.18 and for mortality rate was 1.16.ConclusionsThe findings indicate that 15 days after the lockdown, daily cases of COVID-19 and the growth factor of the disease showed a declined trend, but there was no significant decline in the prevalence and mortality.
Highlights
This study aimed to assess the impact of 15 days before, 15 days during, and 15 days after the lockdown on the trends in the prevalence and mortality in 27 countries during COVID-19 pandemic
Regarding the impact of lockdown on the prevalence and mortality of the COVID-19 outbreak in 27 countries, we found that 15 days after the lockdown there was no decline in the mean prevalence and the mean number of daily deaths due to COVID-19 compared to 15 days before and 15 days during the lockdown (Tables 2 and 3)
We found that 15 days after the international lockdown there was no significant decline in the mean prevalence and mean mortality rate due to COVID-19 compared to 15 days before and 15 days during the lockdown in 27 countries
Summary
This study aimed to assess the impact of 15 days before, 15 days during, and 15 days after the lockdown on the trends in the prevalence and mortality in 27 countries during COVID-19 pandemic. No established vaccines and pharmacological interventions are known to effectively cure or prevent a COVID-19 infection, and public health measures such as lockdown, quarantine, and social distancing appear to be the only ways to curb the outbreak. The home quarantine, when scientifically and adequately applied and exercised according to modern principles and practices, can be an effective method for preventing the spread of contagious diseases, such as COVID 19. Keeping in view the rapid transmission of COVID-19 cases globally, the present study aimed to investigate the impact of lockdowns for 15 days before, 15 days during and 15 days afterward on international epidemiological trends in the prevalence and mortality of COVID-19 cases
