Global Temporal Patterns of Age Group and Sex Distributions of COVID-19

Abstract

Since the beginning of 2020, COVID-19 has been the biggest public health crisis in the world. To help develop appropriate public health measures and deploy corresponding resources, many governments have been actively tracking COVID-19 in real time within their jurisdictions. However, one of the key unresolved issues is whether COVID-19 was distributed differently among different age groups and between the two sexes in the ongoing pandemic. The objectives of this study were to use publicly available data to investigate the relative distributions of COVID-19 cases, hospitalizations, and deaths among age groups and between the sexes throughout 2020; and to analyze temporal changes in the relative frequencies of COVID-19 for each age group and each sex. Fifteen countries reported age group and/or sex data of patients with COVID-19. Our analyses revealed that different age groups and sexes were distributed differently in COVID-19 cases, hospitalizations, and deaths. However, there were differences among countries in both their age group and sex distributions. Though there was no consistent temporal change across all countries for any age group or either sex in COVID-19 cases, hospitalizations, and deaths, several countries showed statistically significant patterns. We discuss the potential mechanisms for these observations, the limitations of this study, and the implications of our results on the management of this ongoing pandemic.

Analysis of SARS-CoV-2 Genomes from West Java, Indonesia

“…In Indonesia, sequenced samples were comprised of 50.5% female samples and 48.6% male samples (with 0.9% of the samples having no information). In Southeast Asia and Asia, a significantly large proportion of the samples with no information on sex hindered the female-to-male proportion from appearing as 50-50, but still showed a ratio close to 1-1 [ 16 ].…”

Physiological Network Is Disrupted in Severe COVID-19

“…A shift in incidence toward younger groups of age, driven by several complex dynamics, has been identified ( Malmgren et al, 2021 ; Monod et al, 2021 ). Country-specific patterns in these shifts caused by socioeconomic factors provide detail in the changing landscape of this disease ( Leong et al, 2021 ). In Mexico, there appear to be more diseased young men than anywhere else, this is likely due to an underlying epidemic of non-communicable diseases, such as obesity and diabetes ( Monterrubio-Flores et al, 2021 ).…”

The Third Wave of the COVID-19 Arrived in Afghanistan: A Severe Case with Skin Manifestation

“…Also, hospitalizations and deaths are distributed along these age-lines. 12 Therefore, it is essential for all age groups to equally follow hygiene practice and social distance, and to avoid careless behaviors. 13 In this report, we describe the case of a young patient who was in perfect health before the onset of COVID-19 symptoms.…”
