First, we should carefully recall whether we have had close contact with others, and if so, we should first isolate and observe ourselves, prepare for related living matters, and promptly contact community, unit or school organizations for environmental disinfection and epidemic prevention measures. When faced with a public health emergency, moderate fear is a normal and important emotion that helps us to be more alert to the danger and thus respond accordingly. If you have symptoms of discomfort but are afraid to go to the hospital, you can first consult online or by phone at home. If your doctor recommends going to the hospital, you can go there with good protection.
