Different people are affected by COVID-19 in various ways. The symptoms experienced by infected individuals have ranged widely, from little discomfort to serious sickness.
- The susceptibility to and prognosis of severe acute respiratory syndrome caused by coronavirus 2 or coronavirus disease 2019 (COVID-19) have been found to vary greatly amongst individuals and populations. 
- Intervention in public health must take into account these variations and how they affect susceptibility to infection and the severity of disease. 
- The distinctions between the COVID-19 case profiles from China and North America may be due to regional variations in host, environmental, and healthcare-related factors. 
- These inter-population variances, together with intra-population variability, highlight the need to identify how health inequities and inequalities affect the public health response to COVID-19 and can help with preparing for the epidemic's resurgence.
