Insights
Elderly men with chronic conditions faced higher COVID-19 mortality. Older individuals, particularly men, experienced faster disease progression and increased death risk from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in December 2019 led to widespread outbreaks of coronavirus disease 2019 (COVID-19).
- Understanding the clinical and epidemiological characteristics of fatal COVID-19 cases is crucial for public health response.
Purpose of the Study:
- To investigate the clinical and epidemiological characteristics of fatal cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
- To identify risk factors associated with mortality in COVID-19 patients.
Main Methods:
- Retrospective analysis of 50 confirmed fatal cases of SARS-CoV-2 reported in Chinese media from January 16 to February 5, 2020.
- Data collected included demographics, symptom onset, date of death, primary symptoms, and pre-existing chronic conditions.
- Statistical analyses were performed to determine correlations between patient characteristics and outcomes.
Main Results:
- The median age of fatal cases was 70 years.
- Males were 2.33 times more likely to die than females.
- The median time from symptom onset to death was 13 days, significantly shorter (12 days) in individuals aged 65 and older compared to younger patients (17 days).
Conclusions:
- Fatal COVID-19 cases predominantly involved elderly men, often with underlying chronic diseases.
- Older age was associated with a faster progression from symptom onset to death.
- The risk of death from COVID-19 is positively correlated with age, with older men facing a higher likelihood of infection and mortality.
Objectives:
In December 2019, a new type of coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), appeared in Wuhan, China. Serious outbreaks of coronavirus disease 2019 (COVID-19), related to the SARS-CoV-2 virus, have occurred throughout China and the world. Therefore, we intend to shed light on its potential clinical and epidemiological characteristics.
Methods:
In this retrospective study, we included 50 confirmed fatal cases of SARS-CoV-2 reported on Chinese official media networks from January 16, 2020, to February 5, 2020. All the cases were confirmed by local qualified medical and health institutions. Specific information has been released through official channels. According to the contents of the reports, we recorded in detail the gender, age, first symptom date, death date, primary symptoms, chronic fundamental diseases, and other data of the patients, and carried out analyses and discussion.
Results:
In total, 50 fatal cases were reported: median age was 70 y old, and males were 2.33 times more likely to die than females. The median number of days from the first symptom to death was 13, and that length of time tended to be shorter among people aged 65 and older compared with those younger than 65 (12 days vs 17 days; P = 0.046). Therefore, the older patients had fewer number of days from the first symptom to death (r = -0.40; P = 0.012).
Conclusions:
In our study, we found that most of the deaths were elderly men with chronic fundamental diseases, and their COVID-19 progression to death time was shorter. At the same time, we demonstrated that older men are more likely to become infected with COVID-19, and the risk of death is positively correlated with age.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
