Tuberculosis patients don't have to drop out of school during their studies. If the school really lets you drop out of school, you should go to the tuberculosis prevention institution where the school is located for examination, especially for sputum examination and chest X-ray in the morning. There are many classifications of tuberculosis, some are infectious and some are not. According to your examination results, the doctor can give you a satisfactory answer. After getting the certificate from the CDC, submit it to the school and explain the situation to the school. According to the doctor's certificate, if your illness is not contagious, the school can continue to recruit students.
