Underlying Chronic Disease and COVID-19 Infection: A State-of-the-Art Review

In late December 2019, a new coronavirus, called COVID-19 (SARS-CoV-2/2019-nCoV), triggered the outbreak of pneumonia from Wuhan (Han’s seafood market) in China, which is now possessing major public health threats to the world. The objective of this review was to describe the epidemiology of COVID-19 in different chronic diseases and understand the pathophysiological mechanisms by which the virus can lead to the progression of these diseases.

The prevalence of COVID-19 infection has become a clinical threat to the general population and healthcare staff around the world. However, knowledge is limited about this new virus. The most commonly reported conditions are diabetes mellitus, chronic lung disease, and cardiovascular disease.

Effective antiviral therapy and vaccination are currently being evaluated and under-development. What we can do now is the aggressive implementation of infection control measures to prevent the human-human transmission of SARS-CoV-2. Public health services should also monitor the situation. The more the knowledge about this new virus and its prevalence, the better the ability of us to deal with it. It is hoped that we will overcome COVID-19 soon with the discovery of effective vaccines, drugs, and treatments.
