At present, COVID-19 has become a global disease, which poses a great threat to human survival. Because of its high infectivity, high cure rate and low mortality, prevention has become the top priority of infection in COVID-19. Autumn and winter are the seasons with high incidence of infectious diseases, and they are faced with many uncertain factors. The focus of epidemic prevention and control in autumn and winter in COVID-19 is early detection, early isolation and early treatment.

Because both influenza and COVID-19 can spread through respiratory droplets and contact, they are greatly influenced by climate and interpersonal contact. At present, with the drop of temperature, the survival time of respiratory viruses such as COVID-19 and influenza in the external environment has been significantly prolonged, and under the stimulation of cold, the human body's resistance is relatively weak, and the viruses are easy to spread. Various factors indicate that COVID-19 virus may overlap with infectious diseases in autumn and winter, and its early clinical symptoms are similar, which is difficult for ordinary people to distinguish. So pay attention to prevention.

Pay attention to good personal hygiene habits at ordinary times, including: wash your hands frequently and don't touch your eyes, mouth and nose; During the flu season, try to avoid going to crowded places; When family members have influenza patients, they should try to avoid contact with each other, especially when there are elderly people and patients with chronic diseases at home. In addition, because the common cold is self-limited, most patients can be cured within one week by drinking more water, taking more rest and eating lightly, but if they are accompanied by fever, even high fever, cough, chest pain and dyspnea, they should go to the hospital in time.
