Analysis of global trends in deaths is essential to look for the differences in the rates of fatalities. Even within countries, there are differences within these rates. Factors that might impact on the death rates include the temperature and the humidity; other unidentified environmental factors, the urban environment  (i.e., housing density); levels of social deprivation, the age structure of the population and who is affected in that population including co-morbidities within a given community. Also, the virus itself can impact on mortality depending on mutations which can affect its virulence – a viruses ability to infect or damage a host.

Beyond this, the structure and response of a countries health system will also need to be investigated. Some countries have more beds, more critical care facilities. It will be essential to understand whether this leads to earlier referral and better supportive care: essential factors when considering the frail and the very elderly who are particularly vulnerable to succumbing to the effects of the virus.

Analysing deaths per population (as opposed to absolute counts) allows for a better understanding of the variation across countries and regions.

The data on confirmed cases and confirmed deaths is updated daily and is published by the European CDC.
