Introduction
In general, leukemia is a malignant tumor of the hematopoietic system and is not contagious. Daily care should focus on maintaining a clean and well-ventilated living environment for the patient, with regular disinfection of frequently used items. The diet should consist of easily digestible, high-protein foods, avoiding raw, cold, or unclean food to prevent infection. Pay attention to the patient's emotional changes and provide psychological support.
Generally, leukemia is a malignant tumor of the hematopoietic system and is not contagious. The detailed explanation is as follows:
Leukemia originates from abnormal proliferation of hematopoietic stem cells, leading to impaired normal blood cell production. This malignant cellular transformation is a pathological change within the body's own cells and is not caused by pathogens; therefore, it cannot be transmitted to others through air, droplets, or contact. Healthy individuals do not need to worry about contracting the disease when living, eating, or interacting with patients. The development of leukemia is associated with genetic susceptibility and environmental factors, and it lacks the three essential elements required for infectious diseases: source of infection, transmission route, and susceptible population.
In daily care, it is important to maintain a clean and well-ventilated living environment for the patient and regularly disinfect frequently used items. Diet should consist of easily digestible, high-protein foods, avoiding raw, cold, or unclean food to prevent infections. Pay attention to the patient’s emotional changes and provide psychological support. Additionally, closely monitor the patient’s body temperature and the condition of skin and mucous membranes, seeking prompt medical attention if abnormalities such as fever or bleeding occur. Help the patient establish regular作息 habits to enhance physical resilience.
