Symptoms Of Tuberculosis Disease (TB) is a severe infectious disease affecting mainly the lungs. It is caused by a bacteria called Mycobacterium tuberculosis. When a person with TB coughs, sneezes, or sings, they release tiny droplets into the air. If another person breathes in these droplets, they can get infected. This disease spreads easily in crowded places, especially where ventilation is poor.
People with HIV/AIDS or weak immune systems are more likely to get TB. Treatments like antibiotics help, but some TB types are not easily fought off.
Key Takeaways
- Tuberculosis is a serious infectious disease that primarily affects the lungs.
- The tuberculosis bacteria, Mycobacterium tuberculosis, can spread through the air when an infected person coughs, sneezes, or sings.
- People with weakened immune systems, such as those with HIV/AIDS, are at a higher risk of contracting tuberculosis.
- Antibiotics can be used to treat tuberculosis, but some forms of the bacteria have developed drug resistance.
- Tuberculosis can spread easily in crowded or enclosed spaces where people gather.
Introduction to Tuberculosis Disease
Tuberculosis (TB) is an infectious disease that mainly affects the lungs. It can also harm organs like the spine, brain, or kidneys. TB has three stages: primary infection, latent TB infection, and active TB disease.
Definition and Overview
Active TB disease occurs when the immune system can’t stop the infection. Germs then cause disease in the lungs or other body parts. This happens soon after primary infection or years later.
Causes and Risk Factors
Tuberculosis comes from the bacterium Mycobacterium tuberculosis. Those with active TB disease can spread it. They release bacteria-carrying droplets when talking, singing, or sneezing. Inhaling these droplets can lead to an infection. The risk increases in crowded, indoor spaces.
Stages of Tuberculosis Infection
Tuberculosis (TB) infection goes through three main stages: primary infection, latent TB infection, and active TB disease. It’s important to know about these stages to manage and prevent the disease effectively.
Primary TB Infection
At the start, the immune system meets the TB germs. They are called Mycobacterium tuberculosis. The immune system tries to destroy these germs. Sometimes, it’s successful. But other times, some germs survive and grow.
In this initial stage, called primary tb infection, most people show no symptoms.
Latent TB Infection
If the immune system controls the TB germs, a latent tb infection forms. Here, the immune system walls off the germs in the lungs. This keeps the germs from making the person sick. People with latent tb feel fine and can’t spread the disease to others.
Active TB Disease
Sometimes, the immune system can’t control the tb germs. This leads to active tb disease. The germs can grow throughout the lungs or other body parts. Active tb disease can show up soon after primary tb infection. Or, it can happen months or years into a latent tb infection.
Healthcare providers need to recognize these different TB infection stages. It helps them diagnose, treat, and stop the disease from spreading.
Symptoms of Tuberculosis Disease in the Lungs
Active TB starts slowly and gets worse over weeks. You might cough a lot, sometimes with blood. There could also be chest pain, fever, chills, and night sweats. Plus, you might lose weight, feel tired, and not want to eat.
Cough
A bad cough that won’t go away is a key symptom. It might hurt and you could cough up a lot of phlegm or blood.
Coughing up Blood or Mucus
Coughing up blood or mucus may happen with active lung TB. If this occurs, it’s important to see a doctor right away.
Chest Pain
Chest pain while breathing or coughing is common. It might be dull or a sharp ache.
Fever and Chills
People with active TB often have fevers and chills. You might feel very cold and then very hot.
Night Sweats
Night sweats are when you sweat a lot while sleeping. Your clothes and bedding might get wet.
Fatigue and Weakness
Tuberculosis can make you very tired and weak. You might feel bad, even with enough sleep.
TB grows in the lungs and is passed on through the air. When someone coughs or sneezes, they spread TB germs in tiny drops. Others can breathe in these drops and get infected.
Symptoms of Active TB Disease Outside the Lungs
Though TB mainly affects the lungs, it can spread to other body parts. This is called extrapulmonary tuberculosis. Symptoms vary based on where the infection is.
Fever and Night Sweats
Active TB outside the lungs may show up as fever and night sweats. The immune response causes these high body temperatures. This happens no matter where TB is growing in you.
Weight Loss and Loss of Appetite
Other signs include weight loss and loss of appetite. When your body fights TB, you may not want to eat much. This can cause you to lose weight.
Pain Near the Site of Infection
If TB is elsewhere, you might feel pain near the site of infection. It could be in the kidneys, liver, brain, and others. These areas are common for extrapulmonary TB.
Recognizing these symptoms is key. It helps with a quick diagnosis and treatment. If not treated, TB can be very harmful.
Symptoms of Active TB Disease in Children
Symptoms of active tuberculosis (TB) disease in kids change with their age. It’s key to know the different symptoms in kids of various ages. This helps in quick diagnosis and the right treatment.
Infants and Babies
In very young children, TB may show as slow growth or not gaining weight. They might be less active, very fussy, or vomit often. They could also have trouble feeding and a soft spot on their head that sticks out.
These signs are alarming because TB can get bad quickly in kids. Their immune systems are still developing. So, pay close attention to these symptoms.
Young Children (1-12 Years Old)
Kids between 1 and 12 might have a fever that doesn’t go away. They might also lose weight. These signs are sometimes missed or thought to be other illnesses.
It’s very important to watch for these symptoms if your child has been around someone with TB. Testing should be done in areas where TB is common.
Teenagers
Teens with TB show symptoms like adults. This includes a long-lasting cough, chest pain, and coughing up blood. They may also have a fever, chills, and lose weight or feel very tired.
Living in a place where TB is common, or having a weak immune system, can put teens at higher risk. This is even if their symptoms look more like adult TB signs. They need careful observation and testing.
When to See a Doctor
The signs of tuberculosis can look like many other sicknesses. If your symptoms don’t get better with rest, it’s key to talk to a healthcare provider. If you have chest pain, sudden severe headache, or feel confused, get help right away. Problems like seizures, difficulty breathing, or if you cough up blood, need immediate or urgent care. Your doctor can decide if you need to be tested for tuberculosis or something else.
| Symptom | Action |
|---|---|
| Cough up blood | Seek immediate or urgent care |
| Blood in urine or stool | Seek immediate or urgent care |
| Chest pain | Seek emergency care |
| Severe headache | Seek emergency care |
| Confusion | Seek emergency care |
| Seizures | Seek emergency care |
| Difficulty breathing | Seek emergency care |
If your tuberculosis symptoms don’t go away after a few days, see a doctor. They can check if you need tests and start you on the right treatment.
symptoms of tuberculosis disease
The common signs of active tuberculosis (TB) are a bad cough for 3 weeks or more, chest pain, and coughing up blood. You might also have a fever, chills, and feel very tired. This disease can cause night sweats, weight loss, and a loss of appetite too. The symptoms start slowly and can get worse over a few weeks.
Cough
A cough that doesn’t go away for 3 weeks or longer is key in TB. This cough might bring up blood or mucus too.
Fever
Fever shows up in many with active TB. It can come and go or stay, often with chills.
Night Sweats
If you have TB, night sweats that are more than usual can happen. They might show up with a fever.
Weight Loss
You might lose weight without trying if you have TB. Not feeling hungry, along with the disease’s effects, can make you lose weight.
Fatigue
Feeling very tired and weak is common for those with TB. This can really affect your daily life.
Chest Pain
Chest pain can happen, especially with breathing or coughing, if TB affects your lungs.
Loss of Appetite
Having little to no appetite can lead to weight loss with TB. Where the TB germs are is where the symptoms show. Most of the time it’s the lungs that are hit. But, it can spread and affect other parts of the body too.
Diagnosis and Testing
To find out if someone has tuberculosis, doctors use many tests. The Mantoux tuberculin skin test is common. It includes injecting a small amount of tuberculin under the skin. If a hard, raised area shows up in 48-72 hours, it could mean they are infected. Another test option is a blood test. It uses tests like QuantiFERON-TB Gold or T-SPOT.TB. Blood tests work well for those who might have gotten a wrong result from the skin test. Chest X-ray is also important for diagnosing TB. This test shows TB signs in the lungs, like cavities or infiltrates. Doctors often use it with other tests to check for active TB. When TB is suspected, they may also test your sputum. You have to cough up some phlegm. They then check it for the TB bacteria under a microscope or in a lab. This can tell if the infection is active, and what treatment is needed.
| Diagnostic Test | Purpose |
|---|---|
| Mantoux Tuberculin Skin Test | Detects if someone has been infected with TB bacteria, even without active disease |
| Blood Tests (QuantiFERON-TB Gold, T-SPOT.TB) | Also detect TB infection, especially useful for those with false-negative skin test results |
| Chest X-ray | Identifies signs of TB disease in the lungs, such as cavities or infiltrates |
| Sputum Sample Analysis | Examines phlegm for the presence of TB bacteria, helps differentiate latent infection from active disease |
Many tests are used to diagnose tuberculosis. They help doctors know for sure if someone has TB.
These tests also show how to best treat it.
Treatment and Prevention
Tuberculosis is fought with a mix of antibiotic medications. Treatment lasts for 4 to 9 months based on TB kind and how it responds to treatment. It is crucial to finish your treatment completely to avoid drug-resistant TB strains.
To keep TB from spreading, those with active TB must stay isolated. Proper ventilation in shared areas helps prevent TB spread. This keeps those exposed to TB or infected but not contagious safe.
In places where TB is common, a vaccine called Bacillus Calmette-Guerin (BCG) is used. It helps prevent TB. People with latent TB infection can also take medicine to keep the disease from activating.
