Patients with chickenpox can have mild or severe disease, with mild cases not requiring hospitalization and severe cases requiring hospitalization. If you are not hospitalized, you should be sure that your symptoms are mild. If a patient with chickenpox does not have symptoms of fever and the rash on the body is not much, then the first choice is to take oral antiviral drugs, usually acyclovir, and when the chickenpox rash may not come out much after the application of acyclovir, this case can be treated without hospitalization. However, if there is an increase in temperature, it is best to be hospitalized and have the relevant aspects checked, such as liver function, blood count, and C-reactive protein. If there are complications, hospitalization is also required. A possible complication of chickenpox is chickenpox pneumonia, which can cause coughing, coughing and even chest tightness. In case of varicella hepatitis, the patient’s symptoms may not be obvious, but abnormalities can be detected through blood tests for liver function. Also when chickenpox encephalitis occurs, this is likely to be accompanied by a more pronounced headache, and the relief of the headache level is not obvious after the body temperature has dropped to normal. Therefore, if the symptoms of chickenpox are severe, or if these complications occur, hospitalization is necessary.
