In a paper recently published in the Journal of Development Economics, researchers estimated excess all-cause death rates due to the 2019 coronavirus disease (COVID-19) pandemic.
Due to the lack of diagnostic tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), official figures on COVID-19 deaths underestimate deaths. Death registries are being used in developed countries to determine the highest number of deaths caused by the COVID-19 pandemic. However, before the pandemic, only a few emerging countries had complete death records, and the pandemic has strained administrative capacity.
In the existing study, researchers used a representative survey of a panel of families to estimate the top number of all-cause deaths in India from the COVID-19 pandemic.
The main data source for the study was the Consumer Pyramid Household Survey (CPHS), which was a giant, representative survey of Indian families conducted through the Centre for Monitoring the Indian Economy. A set of comparable districts within a state is called a homogeneous region. In each round, which is made up of four-month periods, house samples were visited. However, every one month, a subsample of typical families from across the country is sampled. The maximum recent knowledge we could download for the CPHS, which began in January 2014, is from April 2022. The team began knowledge of the studies from 2015.
The CPHS had a complete list of all families, its main purpose was to estimate family economic parameters. If a family had experienced a death since the last time it was surveyed, usually 4 months ago, it was registered as such on the list. The 2011 Indian census explained rural leadership as a village, and CPHS also provided demographic and income source data for each family member, as well as family location at the district level. The team studied the variation in death rates using these data.
In two steps, the team estimated the excess deaths. Using pre-pandemic information, predicted monthly mortality rates in the absence of a pandemic were estimated. were used to calculate these expected mortality rates. In addition, the team estimated the difference between an individual mortality indicator and the expected individual mortality rate during the pandemic.
The death rate appears to have increased with the COVID-19 pandemic, according to uncompiled CPHS data that was aggregated nationally. However, the significant accumulation in the first wave was attributed in part to families who were excluded from the survey during lockdown and who reported deaths thereafter. The number of deaths in the first wave was probably more lightly distributed. The deaths observed in the official death figures were consistent with the small accumulation in wave 3.
During the national lockdown in April and May 2020, the death rate decreased; However, the remaining months of the pandemic remained at or above the 2019 average. When the pandemic hits, there are 4 peaks. When the lockdown was lifted in June 2020, there was a peak. The team noted that the peak of the first wave occurred in September 2020, while the wave of the moment occurred between March and May 2021, and wave 3 occurred in February 2022. With the exception of the February 2022 peak, all increases were particularly higher than adjacent months and an entire month in 2019. Even the highest peak of 2019 was lower than all the peaks of the first wave and moment.
The estimated mean mortality rate was 0. 787%, which was not particularly different from the estimated global burden of disease. However, the excessive mortality rate of the outbreak was 0. 399%, which showed an abundant accumulation of more than 50%. When the team thought of as the 2019 benchmark, the baseline death rate rose to a peak of 1,038 percent. United States.
When the team divided the COVID-19 pandemic into waves, a general trend was observed at baselines, where excess deaths in the current surge were nearly double that in the first wave, and excess deaths in the third wave were decreasing. The final results of the predictable moment wave as the moment wave with the SARS-CoV-2 delta variant affected India more seriously than the first wave with wild-type SARS-CoV-2 infections. Although the first wave seemed to last longer, the moment when the wave had a peak high enough to compensate for the shorter duration.
Overall, it provided new estimates of excess COVID-19 deaths in India, enriching COVID-19-related studies in the country.
