How to avoid contagion by being exposed to a tuberculosis patient

If it is a negative patient, do not worry too much, try to cover his mouth when coughing, wash his hands frequently, and do not put the utensils together. If it is positive, the patient should be isolated, the patient and family members should wear masks, and after about one to two weeks, the patient's symptoms will disappear and may not be contagious, but the possibility of infection cannot be ruled out, so it is also necessary to pay attention to precautions and try not to stay with the patient. Satisfied.

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many organs, and patients with pulmonary involvement and pulmonary tuberculosis are the most common sources of infection. Tuberculosis is transmitted through a wide range of routes, including respiratory tract, digestive tract, ** and uterus, but it is mainly transmitted through the respiratory tract. The main route of transmission of tuberculosis is through respiratory droplets.

The amount of bacteria excreted by the infectious agent, the frequency of coughing symptoms of the patient, the density of the droplet nucleus containing tuberculosis bacteria in the air, and the degree of close contact with the infectious agent are all important factors affecting the infection. Mycobacterium tuberculosis humanis is the main pathogen of human tuberculosis and is mainly transmitted through the respiratory tract through droplets. All symptoms of pulmonary tuberculosis are non-specific, and the World Health Organization and China have identified cough, sputum production for more than three weeks, or hemoptysis as suspected pulmonary tuberculosis symptoms.

The main types are primary pulmonary tuberculosis, hematogenous disseminated pulmonary tuberculosis, secondary pulmonary tuberculosis, etc. According to the principle of early, combined, full-course, regular and appropriate amount of chemotherapy, and the whole process of supervision and management, regular chemotherapy can make more than 90% of patients lose their infectivity in two weeks, which is an important preventive measure.

A: Early detection and reasonable** are fundamental measures to prevent tuberculosis; BCG vaccination is one of the effective measures to prevent tuberculosis; Tuberculosis patients should go to the hospital in time**, and antibacterial** and chemotherapy measures can be taken**.

Tuberculosis is a chronic respiratory infection caused by tuberculosis bacteria that infect the human body, and was also known as "tuberculosis disease" in the past. Tuberculosis bacteria can invade all organs throughout the body. Experts remind everyone to do a good job in the prevention of tuberculosis and reduce the spread of tuberculosis.

Tuberculosis (TB) is an infectious disease of the respiratory tract that is mainly spread to others through droplets containing tuberculosis bacteria that are ejected when a sick person coughs, sneezes, or talks loudly. If there are tuberculosis patients in the family, pay attention to the ventilation of the room, keep the indoor air fresh, the patient's clothes should be washed and dried frequently, and the patient's tableware can be boiled and disinfected; Patients should not spit, burn the phlegm on paper, and do not cough or laugh loudly at others at close range to reduce the chance of transmission. In places with high concentrations of people, infectious tuberculosis patients can easily cause the spread of the disease, and in severe cases, it can also cause outbreaks.

Therefore, it is especially important to keep the environment clean and the air flow in the school or group living environment. If there is a tuberculosis patient, especially if the tuberculosis patient is confirmed to be smear-positive after examination, the patient should be removed from the group environment and accepted into a regular **, and can resume study or work after the contagion has disappeared. It is also necessary to ask people who have had close contact with the patient and have suspicious symptoms of pulmonary tuberculosis such as cough and sputum to the local tuberculosis prevention and control institution for necessary examinations, and if abnormalities are found, they should be carried out in time**.

I hope that through the above introduction, we can help you better do a good job in the prevention and treatment of tuberculosis and reduce the infection of tuberculosis.

Tuberculosis is contagious during the infectious period, but it is not certain whether your classmate is tuberculosis or not, and she is only contagious if she is diagnosed with tuberculosis. If your classmate has a cough all the time, you can suggest that she get a chest X-ray, although it is not necessarily tuberculosis, and other diseases of the lungs should be ruled out.

Tuberculosis in tuberculosis is a contagious disease, other tuberculosis is not contagious, tuberculosis is mainly transmitted through airborne droplets, prevention: you can wear a mask and avoid close contact with tuberculosis patients. Do you mean the peak of tuberculosis when you mean a period of high contagion?

The golden indicator of infection is whether the sputum bacteria are positive, if some patients are highly sensitive to anti-tuberculosis drugs, the effect is good and the phlegm bacteria will turn negative, and they will not be infected, if there are patients with low sensitivity to various anti-tuberculosis drugs, the time may be very long, and his sputum bacteria can not turn negative soon, then his infectious period will be relatively long.

In terms of diet, you should eat more nutritious things, eat more light food, maintain a good mood, do regular physical examinations, you can insist on doing exercises to improve your resistance, and you should also wear a mask, so that you can prevent infection.

You should pay attention to wearing masks, using disinfectants, improving your antibodies, and eating healthy food, so that you can prevent and prevent infection.

Be sure to wash your hands frequently, be sure to ventilate more, eat some nutritious food at ordinary times, enhance the body's immunity, and do not have direct contact with patients.

It is necessary to open the windows regularly, ventilate well, add some nutrients to the body, wash hands more, and pay attention to disinfection.

If there are tuberculosis patients in the family, we must pay attention to the disinfection, isolation and personal protection in daily life. Patients need to live in a separate room, ventilated for 30 minutes in the morning and evening, if possible, it is best to use ultraviolet lamps for more than 30 minutes every day, and boil the tableware and water cups used by the patient for more than 15 minutes.

Manage patients, isolate them, cut off transmission routes, and protect susceptible populations.

1. Do a good job of family isolation. (a) Tell the patient not to face people when coughing, talking loudly, or sneezing, and it is best to cover his mouth and nose with a handkerchief. b. Frequent indoor ventilation. c. Handle the patient's sputum. d. Frequently dry the patient's daily necessities. ）

2. Try not to come into close contact with patients. (5 meters away is safe).

3. After the tuberculosis bacteria are completely reacted in the body, (it takes about a month) you can go to the hospital for PPD test, and if the tuberculin is strong positive, you can take preventive medication. If it is a normal positive or a weak positive, you can rest assured. (A strong positive indicates the presence of active tuberculosis bacteria in the body).

Tuberculosis patients are not all infectious, and patients who shed bacteria (infectious) lose their ability to be infected after 1-3 months of effectiveness, at this time, there is no harm to others.

Except for the respiratory tract, it is not easy to be infected. Such as: eating together, sharing utensils, etc. It is difficult for bacteria to pass through the barrier of stomach acid. Be careful if there is a break in the mouth or esophagus. (Separate meals, separate utensils).
