Tuberculosis (TB) is a contagious sickness that affects the lungs. It can also spread to other regions of the body, such as the brain and spine. It is caused by a bacterium known as Mycobacterium tuberculosis. The virus can be passed from person to person through droplets of saliva or sputum that are coughed or sneezed into the air when an infected person coughs or breathes out vapor. Someone who is not sick cannot get TB; however, someone can get infected with the bacteria that cause it.
In addition to humans, TB can be found in animals such as cows, pigs, and monkeys. It is possible for an animal to be infected with TB but not show any signs of illness. This is because the bacteria live inside cells of their body that produce antibodies to protect them. If an animal becomes ill with another disease, such as leptospirosis or rabies, then doctors may be able to tell that it had TB recently by looking at its lung tissue under a microscope.
An individual who is infected with the bacteria but not yet sick is called a carrier. Carriers can pass on the infection by breathing in tiny particles containing the bacteria. If you are living with an infected person, your doctor may recommend tests to make sure you do not have the disease.
Tuberculosis (TB) is an infectious illness that mostly affects the lungs. The germs that cause TB move from person to person by small droplets discharged into the air by coughing and sneezing. These particles can land in a new person if they don't get blown away by the wind or caught by a guardrail.
The only way to catch TB is from someone who has it. Someone infected with TB may not know they have it, so they can pass it on even if they aren't showing any signs of illness.
If you are exposed to TB and don't take steps to protect yourself, it's possible that you could develop active TB. Active TB means that your body has fought off infection with the help of antibiotics drugs but that you still carry the bacteria inside you which can later grow back into active TB should the immune system be weakened during some future encounter with TB.
The most common method of transmission is through the air when someone with active TB breaks out in a cold or cough. This virus-laden fluid is spread by sneezing and coughing into objects such as handrails and door handles and then into hands that touch these objects. Active TB can also be passed from mother to baby during pregnancy or after delivery if the mother has active TB.
Tuberculosis (TB) is caused by a bacterium known as Mycobacterium tuberculosis. It spreads when someone with active tuberculosis in their lungs coughs or sneezes and someone else inhales the ejected droplets, which contain tuberculosis germs. The people most at risk of getting tuberculosis are those who work with animals or animal products, such as farmers, veterinarians, zoo staff members, or people who work in meat processing plants. Other groups that may be at increased risk include people who live or have lived in poverty, immigrants from countries where TB is common, people who use drugs, and individuals who share rooms with tuberculosis patients.
TB is an infectious disease that can spread through the air when someone with tuberculosis coughs or sneezes. People can also get infected with TB if they touch objects such as needles that contain the bacteria and then put their hands in their mouths.
Active tuberculosis looks like a serious illness involving many systems in the body. If not treated, it can lead to death. The main problem with active tuberculosis is that nobody knows exactly what will happen with their infection. Some people recover completely while others die. There is no way to tell how someone will react to the tuberculosis bacillus unless they get infected and develop the disease.
The best defense against tuberculosis is a series of vaccines called Bacille Calmette-Guérin (BCG).
Mycobacterium tuberculosis is the bacterium that causes tuberculosis (TB). The bacterium often assaults the lungs, but tuberculosis bacteria can attack any region of the body, including the kidney, spine, and brain. Not everyone infected with tuberculosis becomes ill. Those who are genetically susceptible may develop the disease when they come into contact with someone who is infected. Otherwise healthy people can become infected through close contact with an individual who has the disease.
Tuberculosis is a chronic disease that can recur if the patient fails to complete his or her course of treatment. If untreated, this disease can be fatal. In fact, tuberculosis is one of the leading causes of death from a single infection.
How does tuberculosis spread? Tuberculosis spreads when people with tuberculosis cough droplets containing the bacteria into the air when they breathe or talk. These droplets can land in the mouths or noses of someone who is breathing deeply or using a nasal spray, causing them to get sick too. People who are not vaccinated against tuberculosis may be at risk for getting sick if they come in contact with someone who has the disease.
What are the symptoms of tuberculosis? Symptoms usually appear 6-12 months after exposure to M. tuberculosis and can take up to 20 years to appear for those who are infected but do not show signs of illness.
Tuberculosis (TB) is an airborne bacterial illness caused by the organism Mycobacterium tuberculosis that usually affects the lungs, but other organs and tissues may also be affected. The number of people worldwide who develop TB disease is estimated to be about 9 million people per year. About 2 million of these cases are among people who are infected with HIV. Other at-risk groups include individuals who have received kidney transplants, are treated with immunosuppressive drugs, or have cancer treatments that damage the immune system.
The only way to be sure you do not get TB is by testing for it. If you have been in areas where there is a high rate of TB and have not been able to find out whether you have been exposed to it, then you should be tested.
Anyone can get TB, but some people are more likely to develop it. These factors may play a role in someone's risk of getting TB: their age, how their body is fighting off the infection, how long they live with the disease, and whether they are infected with the HIV virus.
People who are most at risk of dying from TB are those who suffer from the disease without proper treatment.
Tuberculosis (TB) is a disease caused by bacteria that spread via the air from person to person. TB most commonly affects the lungs, but it can also affect other regions of the body such as the brain, kidneys, or spine. If a person with tuberculosis does not receive treatment, they may die. The only way to prevent TB is through vaccination and regular screening tests.
The abbreviation "tb" comes from the Latin word for bubble or blob, because the bacteria that cause the disease look like little bubbles under the microscope.
People who are infected with the bacteria that cause tuberculosis but do not show any symptoms of the disease are called carriers. Carriers can pass the bacteria on to others via their respiratory secretions. Children of infected parents are at particular risk of getting sick because their immune systems are not fully developed. If you are around someone who is coughing repeatedly, ask them if they have tuberculosis. If they do, then avoid them until they have completed their treatment course.
In Western countries, people get tuberculosis mainly from close contacts with individuals who have the disease. This is because most cases of tuberculosis in these countries are due to Mycobacterium tuberculosis, the bacterium that causes tuberculosis. About 10% of people with tuberculosis infection will develop the disease. Factors that determine whether this happens include age, size, and extent of the lung lesions, type of host defense against the bacteria, and presence of other diseases.
