It will start school in two days. In order to ensure that teachers and students start a new learning life in an orderly manner, not long ago, Beijing issued a notice requesting new students to complete the tuberculosis screening work. Why do new students enrollment screen tuberculosis?

The tuberculosis has not been far away from us

When it comes to tuberculosis, everyone is no stranger, but there are not a few people who think that tuberculosis has become a "past style".

Tuberculosis is a major infectious disease that seriously endangers people's health and public health and safety. Tuberculosis forms tuberculosis lesions in human lungs. Patients are very likely to heal themselves, and they must be regulated by regulating anti -tuberculosis treatment to recover. If it is found that it is not timely or the treatment is not thorough, the speed of the tuberculosis disease will be very slow, and it may worsen and spread repeatedly. Reline and even cause death.

According to the "Global Tuberculosis Report of 2021" issued by the World Health Organization, we are estimated that in 2020, there are about 842,000 new tuberculosis patients in my country.

Why do you have to check tuberculosis?

Like the new coronary pneumonia, tuberculosis is also a respiratory infectious disease, and it is easy to spread in dense places in personnel. The school is a typical personnel dense place and a key place for tuberculosis control. If the tuberculosis patients in the school are not discovered in time, it is easy to cause spread and cause a clustered epidemic.

The development of new lung tuberculosis screening is mainly to prevent admission to patients with tuberculosis and eliminate hidden dangers to threaten teachers and students' health and campus safety. At present, tuberculosis screening has become a necessary condition for new students.

Fresh and new screening methods in each semester

According to the incidence and its characteristics of the tuberculosis of students in different ages, the teasage tuberculosis screening methods are different.

1. New students of non -boarding admission of children, primary and junior high schools, and pre -enrollment medical examinations should be asked about the history of close contact with tuberculosis and suspicious symptoms of lung tuberculosis; those who have close contact with tuberculosis or suspicious symptoms of tuberculosis must carry out tuberculosis bacteria Skin skin test; those who are positive and above the tuberculin skin test should be performed for X -ray chest slices.

2. Freshmen admitted by senior middle schools and new students admitted to junior high school boarding, before enrollment, they should conduct all tuberculosis suspicious symptoms and tuberculin skin tests; Those who need to check the X -ray breasts.

3. New students in colleges and universities should adopt suspicious symptoms of tuberculosis and X -ray breasts; conditions with conditions can also conduct tuberculin skin tests at the same time.

The similarities and differences between tuberculosis and new crown pneumonia

Although the main organs of tuberculosis and new crown pneumonia are lungs, the clinical manifestations of the two are significantly different.

The tuberculosis is a chronic respiratory infectious disease. When the onset is hidden, the symptoms are not typical and not obvious when the onset starts. Most patients don't know when they are uncomfortable.

There are two main clinical symptoms of tuberculosis: First, the symptoms caused by lung damage caused by the formation of tuberculosis lesions in the lungs are manifested as cough and sputum. If the lesion destroys the blood vessels, blood will occur in sputum. Second, the symptoms of systemic poisoning caused by tuberculosis infections are manifested as systemic discomfort, fatigue, loss of appetite, and decreased weight. Female patients will also have plant nerve disturbances.

Unlike the tuberculosis, the new crown pneumonia is acute respiratory infectious diseases. The symptoms are fever, fatigue, and dry cough, and gradually occur in breathing difficulties. New crown pneumonia is inacular, and generally there is a clear starting point. Most people can make it clear that or even a few points starts to be uncomfortable.

Under the normalization of new crown pneumonia, the clinical manifestations and characteristics of tuberculosis are fully considered, and the difference between the new crown pneumonia will help improve the screening effect of neonatal tuberculosis.
