Tuberculosis
Understanding Tuberculosis
Tuberculosis (TB) is one of the top 10 causes of death worldwide.
Seven countries accounted for 64% of the total, with India recording the highest number, followed by Indonesia, China, the Philippines, Pakistan, Nigeria, and South Africa.
Early intervention can minimize brain damage and the risk of complications.
The good news is that strokes can be prevented.
All of these procedures improve blood flow to the heart, but they do not cure coronary heart disease. Preventing heart disease is the key.
How does tuberculosis affect your body?
A TB infection doesn't necessarily mean you'll get sick. There are two forms of this disease:
Latent TB
Germs are inside your body, but immune system prevent it from spreading.
This means you have no symptoms and are not spreading the disease.
However, the infection remains in the body and may become active one day.
If you are at high risk of reactivation—for example, if you have HIV, your initial infection occurred within the last 2 years, your chest X-ray results are abnormal, or your immune system is compromised—your doctor will prescribe antibiotics to reduce the risk of developing active TB.
Active TB
This means that germs multiply and can make you sick.
You can spread the disease to others.
Ninety percent of active TB cases in adults result from the reactivation of latent TB infection.
What are the risk factors for TB?
Tuberculosis primarily affects adults in their most productive years.
However, all age groups are at risk. More than 951 TP3T cases and deaths have occurred in developing countries.
People infected with HIV are 20 to 30 times more likely to develop active TB (see the section on TB and HIV below).
The risk of active TB is also higher in people with other conditions that weaken the immune system.
Tobacco use significantly increases the risk of tuberculosis and death.
The risk of contracting TB is highest among people who have close contact with others who are infected.
This group includes:
• Family members and friends of someone with infectious tuberculosis
• People who have immigrated from regions of the world with high rates of tuberculosis
• People in groups with high rates of TB transmission, including people experiencing homelessness, people who inject drugs, and people living with HIV
• People who work or live in facilities or institutions that house individuals at high risk of TB, such as hospitals, homeless shelters, correctional facilities, nursing homes, and housing for people with HIV
Not everyone infected with the TB bacterium (latent TB) develops clinically active TB.
People at the highest risk of developing active TB are those with weakened immune systems, including:
• Infants and young children whose immune systems are not yet fully developed
• People with chronic conditions such as diabetes or kidney disease
• People with HIV/AIDS
• Organ transplant recipients
• Cancer patients undergoing chemotherapy
• People receiving certain specialized treatments for autoimmune disorders, such as rheumatoid arthritis or Crohn's disease
Symptoms
Common symptoms of active pulmonary TB include:
01
A cough with phlegm, sometimes accompanied by blood
02
Chest pain
03
Weak
04
Weight loss
05
Fever
06
Night Sweats
Diagnosis
01
Many countries still rely on a long-established method—microscopic examination of sputum smears—to diagnose TB.
02
The use of the Xpert MTB/RIF® rapid test has increased significantly since 2010, when the WHO first recommended its use.
03
A diagnosis can be made within 2 hours. The source page states that this test is recommended by the WHO as an initial diagnostic test for all individuals with signs and symptoms of TB.
04
A chest X-ray is also a diagnostic test used to diagnose pulmonary TB, determine the severity of the infection, or monitor improvement during treatment.
Treatment
If you have active tuberculosis, you should seek treatment immediately.
This treatment may involve the use of a number of medicine for 6 to 12 months.
It is important to take all of your medication as prescribed for the entire course of treatment, even if you are already feeling better.
Otherwise, you could get sick again and potentially spread the illness to those around you.
Active, drug-sensitive tuberculosis is treated with a standard 6-month regimen consisting of four antimicrobial drugs, accompanied by information, monitoring, and support for patients provided by health care workers or trained volunteers.
Without that support, compliance Resistance to treatment can make it difficult to treat, and the disease can spread.
Most cases of TB can be cured when medication is provided and taken correctly.
With the right treatment, tuberculosis (abbreviated as TB) is almost always curable.
If you do not take your medication correctly, the TB bacteria that are still alive can become drug-resistant. Or, sometimes when the antibiotics used to treat the disease do not work, this condition is called drug-resistant TB.
If you have this form of the disease, you may need to take stronger medication for a longer period of time.
Prevention
Preventing TB infection means preventing its spread. It is very important to understand that although TB is contagious, it is also preventable, and preventing TB is better than treating it.
01
Fruits, vegetables, and a variety of foods
BCG (Calmette-Guérin Bacillus) is a live vaccine against tuberculosis. The vaccine is made from an attenuated strain of bovine tuberculosis bacilli, Mycobacterium bovis. This vaccine is one of the most widely used vaccines worldwide.
02
Early Diagnosis
Early diagnosis and treatment are the most effective ways to prevent the spread of tuberculosis. Once diagnosed with TB and treatment has begun, most patients are no longer contagious after just two weeks of taking medication.
03
Case Detection
Outreach workers and volunteers can work in communities with high rates of TB to identify people with symptoms and refer them for testing.
Limiting the spread of TB depends on successfully identifying and treating people who are sick so that they do not transmit the disease to others. This can be achieved by raising awareness about TB so that people with TB symptoms know they need to seek help.
04
Environmental Modifications
Because TB is an airborne infection, TB bacteria are released into the air when a person with infectious TB coughs or sneezes.
The risk of infection can be reduced by taking a few simple preventive measures:
• Maintain good ventilation: TB can remain airborne for several hours if there is no ventilation.
• Preserve natural light: UV light kills TB bacteria.
• Practice good hygiene: Covering your mouth and nose when you cough or sneeze reduces the spread of TB bacteria (cough etiquette).
• Wash your hands after covering a cough or sneeze (hand hygiene).
In healthcare facilities, the spread of TB is reduced through the use of protective masks, ventilation systems, the isolation of patients who may transmit the disease from other patients, and routine TB screening for healthcare workers.
