Is tuberculosis still contagious after taking medicine for more than 6 months?

In tuberculosis patients, tuberculosis patients are only contagious if they are found to have tuberculosis bacteria in their sputum on microscopic examination. With the source of infection, TB bacteria must also pass through certain routes before they can be transmitted to others. Respiratory transmission is the main route of TB infection.

When a tuberculosis patient coughs, sneezes, or speaks loudly, a large amount of tiny sputum containing tuberculosis bacteria is discharged into the air, and healthy people inhale the sputum containing tuberculosis bacteria, which will be inspired. The degree of tuberculosis infection is mainly affected by factors such as the amount of bacteria excreted by tuberculosis patients, the severity of cough symptoms, and the degree of exposure. If there are people with tuberculosis in their homes, nurseries, kindergartens, primary schools or offices, they are more susceptible to tuberculosis bacteria in their surroundings, especially children.

Tuberculosis infection usually occurs before detection and diagnosis, i.e. when no obvious symptoms are detected. In time, the contagiousness of tuberculosis quickly weakens and disappears. In the days after chemotherapy, the number of tuberculosis bacteria in the sputum of the patient decreases dramatically, and even if a small number of tuberculosis bacteria are still present in the sputum, their activity is significantly reduced, and the patient's cough symptoms gradually decrease or disappear, so general contact with these tuberculosis patients is not contagious.

Is tuberculosis contagious after taking medicine for more than 6 months? Whereas. It is not taking medicine **, for the risk of infection is large, try to disinfect the patient's dishes and chopsticks, Mycobacterium tuberculosis and the benefits.

1. For the sake of the baby's good, it is recommended not to. Now taking medicine, it has a great impact on the baby, in order to tell you about tuberculosis again!! My neighbor's little girl was 20 years old and had tuberculosis, and the doctor told him.

Your tuberculosis is not contagious and will not be contagious, but don't let him eat your food anymore, just in case.

It's clinical**, it's okay.

The reason why it is called tuberculosis is because Mycobacterium tuberculosis can form a form of peripheral inclusions like a nucleus in the human body, so it is more difficult to kill general antibacterial drugs, and most patients become carriers of tuberculosis bacteria. Fortunately, the current level of medicine and ** level is already very high, and it is not refractory, especially the improvement of living standards, which ensures the resistance level of the human body, so there is no problem in restoring health.

However, from the perspective of preventing infectious diseases, patients should consciously maintain contact with others in the process of interaction, such as the use of dining utensils and toiletries should be separated from others to avoid infecting others. In particular, tuberculosis patients pay special attention to the disinfection of sputum and other discharges.

Another correction: tuberculosis is a bacterium, called Mycobacterium tuberculosis, not a virus.

I wish the patient a speedy **.

Agree with the netizen upstairs that the pathogen of tuberculosis is a bacterium and not a virus.

Molecular epidemiological data now suggest that TB patients may also be infected with other types of TB bacteria while taking the drug. For example, if you are infected with susceptible tuberculosis bacteria, but you are infected with drug-resistant tuberculosis bacteria transmitted by drug-resistant tuberculosis patients living in the same room. Therefore, it is important to isolate from other TB patients as much as possible.

After TB is cured, TB bacteria may re-ignite in the body and can also be re-infected, especially in patients with weakened immunity. The immunity of the TB host is mainly played by cellular immunity, that is, the effect of lymphocytes and macrophages killing mycobacteria, rather than the role of antibodies in the body (humoral immunity).

If it is initially treated, there will generally be no new lesions, and there will not be so many ** cases if you have antibodies.

**During the period of physical decline and resistance, we should pay attention to protection to prevent reinfection!

Initial treatment of tuberculosis for at least 6 months, the first principle of tuberculosis is: early, combined, appropriate, regular, and whole. The whole course is ** must be achieved in the course of treatment.

The key to curing tuberculosis is that the patient must be regular**, that is, according to the doctor's requirements, adhere to the medication and complete the full course of treatment, and cannot stop or interrupt the drug at will**. If the patient stops or interrupts the drug at will, it is difficult for the anti-tuberculosis drug to kill the tuberculosis bacteria in the body, and it is likely to be cured again**, once the disease is recurred, the patient's previous drugs will lose their effect, which also means that the tuberculosis bacteria in the body have developed drug resistance, not only is it difficult for the patient, but also will spread the drug-resistant bacteria to the surrounding people.

Although tuberculosis is an infectious disease, only the sputum of open tuberculosis or active tuberculosis is the source of infection.

Tuberculosis is mainly transmitted through the respiratory tract, and when patients with open tuberculosis cough and sneeze, the infected droplets can contaminate the environment and cause the spread of the germs.

One of your brothers has a history of contact with tuberculosis patients, but not all of them will be infected after contact, and he has no symptoms of tuberculosis infection such as cough since he was exposed, so he may not be infected.

You are often with him, and today you are not feeling well and cough and runny nose, which is mostly a symptom of a cold, don't worry too much, if you have any doubts, you can do a chest X-ray and other examinations.

Mycobacterium tuberculosis is a pathogen with strong resistance, which is not easy to be killed, if it is invasive tuberculosis, it is generally not infectious after one month of medication, and if it is cavitary tuberculosis, it is possible to be contagious after two months of medication.

Whether or not it is still infectious after being infected with pulmonary tuberculosis depends on whether the sputum it excretes contains Mycobacterium tuberculosis, and cannot be judged solely on the time of taking the drug.

For people with tuberculosis, drugs can control the disease. To avoid infecting others, patients should take medication as soon as possible.

The medication should be taken early, the combination of drugs should be appropriate, the dosage should not be too large, and the condition should be monitored during the medication.

The course of the disease is generally 6 to 9 months, and the efficacy of the drug is as high as 98%.

Patients with positive sputum bacteria will be contagious and should be isolated. If the family is isolated, the patient's room should be left alone, and the food, eating utensils, and utensils should be separated. Bedding and clothes can be disinfected by exposing them to the sun for 2 hours, and eating utensils can be boiled for 1 minute to kill Mycobacterium tuberculosis.

The room should be well ventilated and sunny, and doors and windows should be opened 3 times a day for 20 to 30 minutes each time. Generally, when the sputum bacteria are negative, the isolation can be lifted.

1. On the contagiousness of tuberculosis: tuberculosis itself is an infectious disease, but the degree of infectivity depends on whether the patient's sputum can be found when Mycobacterium tuberculosis, whether the patient coughs and coughs sputum, and how many times he coughs.

2. Therefore, if the patient has a "negative sputum test and no cough symptoms" at the beginning, the patient will basically not be infected. **After a month, it is even less contagious.

3. If the patient is "sputum test positive" at the beginning, he usually has cough symptoms, and the patient is infectious. **After one month, the infectivity will decrease significantly, and whether it is "infectious" or not should be determined by "sputum test". Generally, the "sputum test" is negative for 3 consecutive months after taking the drug, and the interval between each time is at least one month, so that the results of 3 consecutive negative "sputum tests" can be said to be non-infectious.

It depends on whether your sputum test is negative or positive, and if it is positive, it is definitely contagious. Patients with a negative sputum test are less likely to do so. Pay attention to wearing a mask when going out, and avoid going to crowded places. Tableware is best used separately and can be sterilized by boiling water after use.

It is necessary to look at the results of sputum bacteria examination, and consider the comprehensive consideration of the lesion and symptoms.

Problem analysis: Pulmonary tuberculosis is a slow and slow disease transmitted through the respiratory tract of the exhaled limbs, and the main transmission route is pulmonary tuberculosis excretion, which is transmitted through respiratory droplets, and is generally susceptible. If you are in close contact with a patient in the contagion period, you are at high risk.

Advice: There may also be contagion. The specific whether it will be infected depends on the severity of tuberculosis, for cavitary tuberculosis sputum with tuberculosis bacilli will be infected, if there are no tuberculosis bacilli in the sputum, then it will not be infected.

Problem analysis: Hello, pulmonary tuberculosis is mainly caused by the inflammation caused by the erosion of the lungs by Mycobacterium tuberculosis, often with cough, sputum, hemoptysis, chest pain, night sweats, emaciation and other symptoms, with strong infectiousness, mainly transmitted by droplets, and untreated tuberculosis is the main source of infection.

Yi Sui coarse Li see suggestion:

Generally, after a sufficient amount of standardized anti-tuberculosis**, its infectivity will be greatly reduced, but whether there is still infection, you need to do a sputum test to determine, if multiple sputum tests are negative, it is basically non-infectious.
