If a student is tested positive for COVID-19, the school should take timely and effective measures to protect the health and safety of other students and faculty. This may include suspending the teaching activities of the student's class or school until it is determined that the health and safety of other students and staff are guaranteed.

In addition, schools should actively cooperate with the health department's epidemic prevention and control measures and take necessary isolation measures to screen and isolate close contacts to ensure that the epidemic will not continue to spread.

It should be noted that a positive student test does not mean that the whole class or school needs to be closed. According to the local epidemic situation and the guidance of the health department, the school can formulate corresponding epidemic prevention measures according to the specific situation, such as isolated observation of close contacts, strengthening campus disinfection and ventilation. At the same time, schools should promptly release epidemic prevention and control measures to parents and students, strengthen publicity and education, and remind teachers and students to do personal protection.

In a word, it is a serious epidemic event that students test positive, and schools should take active measures to ensure the health and safety of teachers and students. It is the key to effectively deal with the epidemic situation to formulate epidemic prevention measures and do a good job in publicity, education and protection measures.
