【Abstract】There are a large number of elderly people in China, who often suffer from malnutrition and comorbidities and are susceptible to the infection of 2019 coronavirus(2019-nCoV) because of weakened resistance to pathogens. The mortality rate was significantly higher, and the prognosis was poor for the elderly patients with chronic diseases and complications. Therefore, they are the susceptible and high-risk population of corona virus disease 2019 (COVID-19), accounting for the majority of the critically ill cases in the current outbreak. To effectively cut off the transmission of 2019-nCoV and reduce the infection rate, it is recommended for the elderly people to avoid going out as much as possible. The purpose of this article is to provide guidance for the home-living elderly people to have a sensible diet, to strengthen their awareness of prevention and control, to improve the ability of protection, and to avoid malnutrition caused by the decline of body functions and adverse health consequences.
