The Correlation between Age and Coronavirus Infections

The global outbreak of coronavirus (COVID-19) in 2019 has attracted worldwide attention and increased concerns due to the rapid spread and progression of the disease. Despite the higher risk of death which is linked with COVID-19 in elderly patients, few studies have focused on how the clinical features and prognosis of COVID-19 patients differ between different age groups including 50 years, 50 to 60 years, and people aged above 60. A thorough assessment of age allows physicians to risk-stratify all COVID-19 patients regardless of where they are, as studies have shown that the clinical presentation and prognosis of the disease differ between age groups. Patients over 60 years of age have worse disease severity, more severe clinical symptoms and longer disease duration compared to those under 60 years of age. One of the major challenges facing public health and clinical experts during a pandemic is the diversity of disease severity. Understanding morbidity and mortality by age associated with COVID-19 is critical, as it affects treatment choices, prognostic expectations, and triage. This analysis concluded that patient clinical characteristics and disease prognosis change with age and that careful age assessment can help clinicians worldwide to risk-stratify all COVID-19 patients. In the present review, we do focus on the relationship between ageing and diseases profile or associated morbidities.
