This rapid review of the literature provides a state of knowledge on chronic diseases associated with an increased risk of complications from COVID-19 in adults as it was in December 2020. A total of 109 articles were selected for this work, and the results of 41 studies were analyzed in detail.
Available data showed that:
- The presence of a chronic disease increased the risk of having complications from COVID-19, including death. In particular, cardiovascular diseases, respiratory diseases, liver and kidney diseases, diabetes and obesity emerged as risk factors.
- A combination of comorbidities and advanced age were also significant risk factors for having complications from COVID-19.
- To protect vulnerable people in the context of professional activities, the majority of health authorities advocated teleworking and distancing measures in the workplace. Several recommended eliminating tasks with a high risk of exposure such as those that could lead to contact with suspected or confirmed cases of COVID-19.
