Can tuberculosis infect people, is tuberculosis contagious?

Xinyi Wang Wei will answer for you.

1. How is tuberculosis transmitted?

Cough transmission is the main route of tuberculosis transmission. In addition, if a person with infectious tuberculosis spits, the sputum with tuberculosis bacteria will dry and form tiny floating dust, which may also cause infection if inhaled. Therefore, good habits such as coughing and sneezing and not spitting can reduce the spread of tuberculosis.

2. Are tuberculosis patients infectious?

Not all TB patients are infectious, and smear-positive tuberculosis patients are the main source of TB infection.

3. Will I get tuberculosis if I come into contact with a tuberculosis patient?

Tuberculosis does not necessarily occur in healthy people who are infected with TB bacteria. The occurrence of tuberculosis is mainly related to the number and virulence of infected tuberculosis bacteria and the body's resistance, and the probability of developing tuberculosis in the infected population is about 10% in a lifetime.

4. Who is susceptible to tuberculosis?

In general, all people are susceptible to tuberculosis. People with weakened immunity are susceptible to tuberculosis when infected with TB bacteria. People with weakened immunity are prone to tuberculosis when infected with tuberculosis bacteria, such as young children, malnutrition, the elderly, pneumoconiosis, diabetic patients, HIV infection and long-term immunosuppressant users.

Hope it helps.

Tuberculosis is contagious during active periods, but not during other periods.

Is tuberculosis contagiousThe answer to the question of whether tuberculosis is infectious is yes, in fact, tuberculosis itself is an infectious disease that is produced in the lungs and mainly relies on saliva, so many people are very panicked about tuberculosis patients and are very reluctant to have too close interactions and communication with tuberculosis patients.

Is tuberculosis contagiousIt should be reminded that tuberculosis is contagious, not only in the process of communication, if the other party's saliva enters your mouth, it is likely to cause a more serious infection, because the saliva will contain a certain amount of tuberculosis bacilli, and if tuberculosis patients do not pay attention and spit, it is also very likely that because the saliva contains a certain amount of tuberculosis bacilli, and further let the people passing by this place also be infected. However, in a completely open space, the saliva will be dispersed very quickly, so you don't have to worry about standing in a spot with spit for a minute and getting infected, which has not happened in the past.

That's the answer to the question of is tuberculosis contagious. I want to emphasize to you that although tuberculosis is contagious, in fact, the country has also launched a vaccine, as long as you can be vaccinated in accordance with the country's regulations, you don't have to worry about being infected by tuberculosis.

I don't know the claim that tuberculosis is the "smartest" infectious disease, but tuberculosis is indeed a serious infectious disease that is not usually severe, and its transmission and impact are very complex and pervasive.

Tuberculosis is a disease caused by the bacterium Mycobacterium tuberculosis, which is spread through the air, and infected people can spread the germs to others by coughing, sneezing, talking, etc. Tuberculosis has a long incubation period, symptoms are subtle, and it is easy to go unnoticed, which makes the spread of tuberculosis very difficult to control. In addition, Mycobacterium tuberculosis is able to form a difficult "hidden" state in the body, which means that even if the infected person does not show obvious symptoms, they can still spread the germs, making it more difficult to control and prevent tuberculosis.

Therefore, it can be said that tuberculosis is a very challenging infectious disease that needs to be tackled through comprehensive prevention, control and ** measures. Although there are certain difficulties in the spread and development of tuberculosis, many countries and organizations have invested a lot of resources and energy to deal with this challenge within the scope of the whole nuclear blindness, and have achieved some rift results.

Tuberculosis is probably called the smartest infectious disease because of its characteristics such as the way it spreads and infects, the difficulty of **, and the ability to resist it.

1. Mode of transmission and infection: Pulmonary tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. It is mainly airborne and can spread droplets carrying Mycobacterium tuberculosis into the air when a patient coughs, sneezes, talks, or sings.

Other people can become infected with tuberculosis bacteria after inhaling these droplets. The mode of transmission of Paratonia tuberculosis makes it more susceptible to transmission in crowded living environments and deprived areas.

2. Difficult**: After tuberculosis infection, it is possible to lie dormant in the body for many years without causing symptoms, which is called latent tuberculosis infection. In the case of damage to the immunoculture system, these latent tuberculosis bacteria may become active and cause illness.

In addition, tuberculosis bacteria have a high degree of drug resistance, and often require long-term anti-tuberculosis**, and the ** cycle is long and expensive. This makes tuberculosis more difficult and difficult to completely.

3. Resistance ability: Tuberculosis bacteria have strong survival and replication ability in the patient's body, and have the ability to resist a variety of antibiotics. Therefore, even with anti-tuberculosis**, the bacteria may still have resistance, resulting in unsatisfactory results.

Moreover, if the patient does not fully comply with the doctor's instructions during the ** or ** period, it will make the bacteria resistant to the drug and make it more difficult.

Therefore, tuberculosis is a disease that is difficult to spread, easy to spread, and highly resistant to drugs, which makes tuberculosis one of the most intelligent infectious diseases. To prevent the spread and infection of tuberculosis, we should maintain good personal hygiene, keep the room well ventilated, avoid staying in crowded places for too long, and actively get tested for tuberculosis bacteria.

Tuberculosis is of course infectious, tuberculosis is a chronic infectious disease of the respiratory tract caused by tuberculosis bacillus, infectious diseases must be infectious, infectious diseases have infectious sources, transmission routes and susceptible populations, three links, the main recommendations are the following three points:

Clause. 1. The source of infection is the patient, and the sick person is the source of infection, so tuberculosis should be isolated, and isolation is mainly to isolate the sick patient.

Clause. Second, cutting off the route of transmission means not having close contact with the patient, wearing masks, and washing hands, which is an effective measure to cut off the route of transmission.

Clause. 3. Protecting susceptible populations, such as wearing masks and isolating others, is also effective in protecting susceptible populations, but the most effective protection for tuberculosis is to be vaccinated with BCG after birth, and BCG vaccination can actively immunize and produce antibodies, which can prevent the occurrence of tuberculosis. When vaccinated, it is not 100% that tuberculosis is not avoided, at least the chance of tuberculosis is small, and even if they have tuberculosis, some children may have mild symptoms and are not typical.

Therefore, after each child is born, it is necessary to punch in the intermediate.

It is important to know about tuberculosis that some children have been in contact with their parents, such as those who have tuberculosis and have been in close contact, can also be intervened in tuberculosis, and can use the anti-tuberculosis effect of 3 months as a preventive medicine.

Tuberculosis is a very intelligent infectious disease because it has the following characteristics:

1.Insidious infection: Tuberculosis bacteria can remain dormant in the human body for many years without incurring the onset and not transmitting it to others. In this case, people may not know that they are carrying the germ, i.e., they have a stealthy infection.

2.Drug resistance: Traditional TB** regimens require long-term medication, but bacteria can adapt to anti-TB drugs in a variety of ways, making it increasingly difficult.

3.Spread of germs: Tuberculosis bacteria are spread through the air, released into the air when a person coughs, sneezes, etc., and can survive for several hours in the air, making it easier for the germs to spread.

4.Difficult to detect: Tuberculosis is not easy to detect in the early stages because symptoms such as cough, fatigue and fever are mild, and these symptoms can also occur in other diseases, leading to the advanced stage when the disease may be detected.

In summary, the reason why tuberculosis is considered the smartest infectious disease is because it has the characteristics of insidious infection, drug resistance, transmission of germs, and difficult to detect, which make tuberculosis more difficult to control and control.

Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis, which is considered one of the most intelligent infectious diseases. This is because tuberculosis has the following characteristics:

1.Long incubation period: The incubation period of tuberculosis can be as long as years to decades, during which patients may not develop any clinical symptoms, but they can still transmit the pathogen to others through coughing, sneezing, etc.

This makes tuberculosis very contagious and undetectable, and can breed and spread over a long period of time.

2.Strong drug resistance: due to the mutated energy of Mycobacterium tuberculosis, drug-resistant strains are prone to appear, resulting in the ineffectiveness of traditional anti-tuberculosis drugs, and the formation of multidrug-resistant or extremely drug-resistant tuberculosis, which makes tuberculosis very difficult.

3.The symptoms are relatively hidden: the early symptoms of pulmonary tuberculosis are often not obvious, such as dry cough, slight fever and general tiredness, etc., similar to the symptoms of the common cold, which are easy to be ignored or not timely, thus worsening the condition.

4.Contagious: Tuberculosis is spread through airborne droplets, which can spread Mycobacterium tuberculosis to the surrounding population, especially those who have been in close contact with the patient, when the patient coughs, sneezes, etc.

Moreover, because patients with tuberculosis can have an antibody response for a long time and are still contagious after death, it is very difficult to control the spread of tuberculosis.

To sum up, as an infectious disease, tuberculosis has the characteristics of long incubation period, strong drug resistance, relatively hidden symptoms and strong contagiousness, which makes tuberculosis very complex and difficult to deal with in terms of infection, infection and **, so it is considered to be one of the smartest infectious diseases.
