Exploring Age, Gender and Pandemic Dynamics: A Retrospective Analysis of the Impact of SARS-CoV-2 on Human Health

The deaths due to the SARS-CoV-2 virus increased rapidly over a short period of time. From the beginning of the pandemic until September 2024, the number of COVID-19 cases reached 776,205,140 cases, with 7,064,380 deaths worldwide. The total number of deaths recorded from the beginning of the pandemic until September 2024 represents a share of 0.09% of the total world population and 0.91% of the total infected population.

The data in this study were collected from the Ministry of Internal Affairs of Romania, Eurostat, NIS and WHO sites, and analyzed using Microsoft Excel and SPSS 22 in order to detect the evolution trends during the state of emergency, the share of infection and deaths among the European countries and worldwide, differences between gender categories or age groups and to identify factors that can be related to the incidence of infection and mortality due to COVID-19.

Males registered a significant higher number of deaths compared to women in Romania, a trend that aligns with global tendencies (p < 0.05). Also, the 70-79 age group had the highest mortality rate, followed by the over 80 age group and the 60-69 age group. Therefore, the risk of death from COVID-19 increases significantly with age. A good health education may be essential in order to promote a high life expectancy. A higher life expectancy correlated with a lower rate of mortality. BMI can be a factor contributing to the increased comorbidities, and may influence the fatality levels of COVID-19.
