Many countries in the world have faced with coronavirus disease 2019 (COVID-19) epidemic since December 2019, while the proportion of elderly patients with COVID-19 in severe and death cases is relatively high. At present, China is in the rapid development stage of population aging, and the demand of the elderly for medical care, health care, nursing and life services far exceeds that of other people. Especially in the period of COVID-19, it is particularly urgent to summarize more experience and methods in time to reduce the infection rate, the incidence of critical illness, and the mortality rate. Therefore, this review combines the existing research results with clinic experience of diagnosis and treatment for senile infectious diseases, summarizes the clinical characteristics and puts forward the prevention strategies of elderly COVID-19 patients, which provide evidence for effective prevention and treatment of COVID-19 in elderly patients, improvement of cure rate, and reduction of severe incidence rate and mortality.
