What is known in male gender differences, comorbidity and age for COVID-19 pandemia? A narrative minireview

Background. On March 2020, WHO declares the world pandemic by COVID-19. In this report we report the COVID-19 infection, related to male gender, comorbidity and special population. 
Data resources. We describe the published studies by PubMed, Medscape and Scopus between December 2019 to May 2020. Keywords used: male/man gender, sex differences, COVID-19, comorbidity, diabetes, hypertension, elderly, pregnancy, children. 
Results. The elderly population and infants are a population at higher risk. The comorbidities are risk factors for the development of a more severe form of disease. There may be a sex predisposition to COVID-19 infection, with men more prone to be affected. 83.9% of COVID-19 patients with chronic kidney disease (CKD) and 57.3% of COVID-19 patients with liver diseases, have a severe disease. 
Conclusions. Older age, infants, male gender and comorbidity describe a crucial role for severity of COVID-19 disease. Future studies are need for the management of these patients.
