Tuberculosis is a national infectious disease, and its main clinical manifestations are coughing, coughing, hot flashes, night sweats, even blood in the sputum, and body wasting. Tuberculosis autoimmune function is relatively low, which makes it easy to complicate respiratory infections, especially upper respiratory tract infections. Once a TB patient is accompanied by prolonged sneezing, he or she needs to be alert to allergic rhinitis and upper respiratory tract infections caused by low autoimmune function. If the blood count indicates a decrease in total white blood cells and an increase in lymphocytes, this indicates a combination of viral colds and requires strengthening of autoimmune function. Drugs such as transfer factor, interferon and thymidine can be given to enhance the cellular immune function and improve the symptoms of respiratory allergy. In case of allergic rhinitis, anti-inflammatory and anti-allergic treatment such as montelukast sodium and epalrestin can be added to relieve the symptoms of sneezing. Tuberculosis is easily combined with various upper respiratory tract infections due to low autoimmune function, and needs to be identified during treatment.
