Sequelae after recovery from delta pneumonia vary depending on the individual’s constitution, with common sequelae including persistent coughing, loss of smell and taste, and other conditions. Delta belongs to a branch of the novel coronavirus, and even after recovery, different sequelae may occur depending on the individual’s physical condition, the duration of the disease, and the effectiveness of treatment. Common sequelae include persistent cough, fatigue, muscle weakness, joint pain, chest tightness and shortness of breath, palpitations, hair loss, chest pain, mood disorders, headache, sore throat, skin rashes, loss of appetite, impairment of the senses of taste and smell (or even loss of the senses of taste and smell), diarrhea or vomiting. Delta virus is a new mutated strain that has emerged in recent years, and the study of its sequelae is not yet adequate. Delta virus has a rapid transmission capacity, so you should pay attention to wearing masks when you go out, wash your hands frequently, pay attention to personal hygiene, and pay attention to keeping warm.
