Can patients who are positive for the new coronavirus take a shower?

　　A positive result for the novel coronavirus indicates a positive nucleic acid test for SARS-CoV-2. Generally, if a patient tests positive for the virus but does not exhibit significant symptoms, taking a shower is acceptable. However, if symptoms such as fever and cough have already appeared, showering may not be recommended. It is advised that patients promptly visit a hospital and follow medical guidance for treatment. Detailed analysis is as follows:

　　If a patient has tested positive for SARS-CoV-2 nucleic acid but has not developed apparent symptoms, they are considered asymptomatic with a relatively stable physical condition, and showering is generally permissible. Bathing can promote blood circulation, alleviate symptoms such as fatigue, headache, and muscle pain caused by the virus, provide physical cooling effects, help relieve fatigue, improve sleep quality, and positively contribute to recovery. After bathing, it is important to dry off promptly and avoid staying in cold or damp environments to prevent catching a chill, which could worsen the condition.

　　Patients with severe illness or symptoms such as high fever and extreme fatigue should avoid showering. At this stage, the patient's physical condition is weak, and bathing may lead to excessive energy consumption, increased burden on the heart, and even possible falls due to physical exhaustion, causing secondary injuries. Additionally, during fever, blood vessels expand, and taking a hot shower may further elevate body temperature, which is not conducive to reducing fever.

　　Patients who have tested positive for SARS-CoV-2 nucleic acid and are isolating at home should ensure good ventilation in the bathroom while showering. Personal items used should be washed and disinfected separately after use to prevent cross-infection.
