24 March World Tuberculosis Day: Know Tuberculosis, Detect it Early, Prevent Infection

Tuberculosis (TB) is one of the infectious diseases that still maintains its importance in the world and in Turkey, despite the development of modern medicine. 24 March World Tuberculosis DayIt is a strong awareness day that reminds us that the disease can be controlled with early diagnosis and correct treatment. Accessing accurate information about tuberculosis; It reduces delayed diagnosis, chain of transmission and unnecessary anxiety. 

In this guide, we will discuss step by step how tuberculosis is transmitted, its symptoms, diagnosis process, treatment plan and ways to prevent it. The most critical message is this: Tuberculosis spreads if “neglected”; It can be treated “if caught early”. If you have suspicious symptoms, consulting a specialist as a first step is protective for both you and your environment. 

Why is World Tuberculosis Day commemorated on March 24?

March 24, the causative agent of tuberculosis Mycobacterium tuberculosis It is a symbolic day marking the date when bacteria were scientifically identified. This awareness day; It aims to increase the level of knowledge about tuberculosis in the society, increase early application and reduce stigma. Because tuberculosis is not only a "medical" but also a "social" issue: Early diagnosis reduces transmission; Proper treatment makes recovery possible.

The greatest power in controlling tuberculosis is regular screenings and taking symptoms seriously and accessing healthcare in a timely manner. For this reason, World Tuberculosis Day is not to "scare"; It should be considered as a reminder to "recognize early and take the right steps".

What is Tuberculosis?

Tuberculosis, mostly affecting the lungs; However, it is a bacterial infection that can also be seen in different organs such as lymph nodes, bones, kidneys and meninges. The disease can be contagious in the case of "active tuberculosis". "Latent tuberculosis infection" is a situation in which the disease has not developed and contagiousness has not occurred even though the person has bacteria.

The clinical picture of tuberculosis may vary from person to person. In some people, symptoms progress slowly and insidiously; This may lead to late detection of the disease. Therefore, symptoms such as prolonged cough, unexplained weight loss, and night sweats should not be ignored.

How Is Tuberculosis Transmitted?

Tuberculosis, usually by airgets infected. Very small droplets released into the air when a person with active pulmonary tuberculosis coughs, sneezes or speaks can be inhaled by people sharing the same environment. Risk of contamination; It increases in situations such as being in closed spaces for a long time, inadequate ventilation, and the sick person not receiving treatment.

Transmission typically does not occur through contact such as "using the same plate", "shaking hands" or "touching the same object". Knowing this distinction both reduces unnecessary fear and allows you to focus on real protection methods. Contact evaluation is important if there is a history of long-term, close contact at home or at work.

Situations That Increase the Risk of Infection

Transmission of tuberculosis and activation of the disease may be easier under some conditions.

• Closed and crowded environments: In areas with poor ventilation, the possibility of bacteria hanging in the air increases.

• Prolonged close contact: Living in the same house or frequently sharing the same indoor environment increases the risk.

• Active patient not receiving treatment: Contagiousness is higher in the untreated period.

• immune system weakness: The risk of the infection turning into a disease may increase in some people.

What are the symptoms of tuberculosis?

Symptoms of tuberculosis may often be ignored because they start "like the flu" and last longer. However, especially Cough lasting more than 2–3 weeks Findings such as these may require evaluation. Symptoms are not limited to the lungs; Different signs may also be seen depending on the organ involved.

The following symptoms alone do not provide a definitive diagnosis; but lasting for a long time, increasing, or occurring more than once requires medical evaluation. Early application is even more important, especially in risk groups.

Pulmonary Tuberculosis Symptoms

These symptoms are prominent in pulmonary tuberculosis, which is the most common form.

• prolonged cough: A gradually increasing cough that lasts longer than 2–3 weeks is noteworthy.

• expectoration: Ongoing sputum, sometimes bloody sputum may be observed.

• chest pain: A feeling of increased pain or pressure may occur when breathing.

• shortness of breath: It may be accompanied by shortness of breath, especially with exertion.

General (Systemic) Symptoms

Tuberculosis can manifest itself not only in the lungs, but also with symptoms affecting the whole body.

• night sweats: There may be intense sweating, especially to the point of changing pajamas.

• unexplained weight loss: It can be seen with decreased appetite, without dieting.

• Weakness and fatigue: Permanent fatigue may occur, reducing daily performance.

• fire that doesn't fall: Prolonged mild fever or fever that rises in the evening may be observed.

What Can Happen in Extrapulmonary Tuberculosis?

In extrapulmonary tuberculosis, symptoms depend on the organ involved.

• swelling in lymph nodes: Painless, permanent swelling may occur in the neck.

• Bone-joint pain: Ongoing back pain or joint pain may come to the fore.

• Urinary tract complaints: In some cases, there may be symptoms such as blood in the urine and frequent urination.

• Severe headache/stiff neck: Meningitis tuberculosis, a rare but serious condition, may require urgent evaluation.

Who is at Higher Risk?

Tuberculosis can occur in anyone; However, the risk of developing the disease and the possibility of complications are higher in some groups. The term "risk" here does not mean that the person will definitely have tuberculosis; It just tells us that we need to be more careful in terms of follow-up and early evaluation.

If risk groups have symptoms such as long-lasting cough, night sweats, and weight loss, it is a better approach to consult a physician instead of "waiting and hoping it will go away." This is a critical step for both early diagnosis and protection of contacts.

Risk Groups

• Immunocompromised people: Some chronic diseases or treatments that lower immunity may pose a risk.

• close contacts: Those who have long-term close contact, such as domestic contact, are monitored more carefully.

• Crowded living conditions: The risk may increase in closed, poorly ventilated and crowded environments.

• Malnutrition and severe stress conditions: When the general health condition weakens, disease development may become easier.

How to Diagnose Tuberculosis?

The diagnosis of tuberculosis is not made by looking at a single finding; Clinical evaluation and appropriate tests need to be interpreted together. The physician evaluates the duration of symptoms, contact history, risk factors and examination findings. Then, necessary imaging and laboratory tests are planned.

The important point in the diagnosis process is this: Tuberculosis is a disease that can be detected with the right tests. However, the timing of the tests, sample quality and accurate interpretation are very valuable. Therefore, if there is any doubt, it is necessary to plan the process with a specialist.

Methods Used in Diagnosis

• Chest X-ray/imaging: Findings compatible with tuberculosis can be investigated in the lungs.

• sputum examination: Evaluation can be made through a sample to show the bacteria.

• Tuberculin skin test (PPD) / IGRA tests: It can be used to evaluate exposure to infection.

• Clinical evaluation and contact screening: If there is domestic contact, evaluation of the contacts can be planned.

How to Treat Tuberculosis?

Tuberculosis treatment is a process that is carried out under the supervision of a physician and requires regular follow-up. The main goal of treatment is; The aim is to completely clean the bacteria, cure the patient and end the contagion. Therefore, it is very important to apply the treatment regularly, not to skip medications and not to miss follow-up appointments.

Treatment duration and plan; It may vary depending on the location of the disease, its clinical severity and some special conditions. The most critical issue is that the person does not stop taking the medication when he or she starts to feel better. Early discontinuation of treatment may pave the way for disease recurrence and the development of drug resistance.

Why is it so important to use medications regularly?

• reduce contagion: With regular treatment, the risk of transmission decreases significantly.

• Aiming for full recovery: Order is required to completely clean the bacteria.

• Prevent the development of resistance: Irregular use may increase the risk of drug-resistant tuberculosis.

• reduce the risk of relapse: Unfinished treatment may cause the disease to return.

Ways to Prevent Tuberculosis

Protection from tuberculosis; It is based on breaking the chain of transmission and preventing the disease from becoming active. The most effective approach to protection; People with active tuberculosis need to be diagnosed early and start treatment quickly. This is the most powerful step to reduce transmission at the community level.

At the individual level, it is important to perform ventilation, cough hygiene, evaluation of contacts and screenings recommended by the physician in risky environments. In case of "doubt", seeking expert opinion without delay both reduces anxiety and enables early management of a possible risk.

Practical Protection Steps

• ambient ventilation: Regular ventilation of closed areas can reduce the risk of contamination.

• Cough hygiene: It is important to cover your mouth and nose when coughing and use disposable tissues.

• Evaluation of contacts: If there is household or close contact, screening can be done with the guidance of a physician.

• Do not wait if the symptom persists: Evaluation should not be delayed in cases of symptoms such as cough lasting more than 2-3 weeks.

When should you consult a doctor if tuberculosis is suspected?

Some symptoms can be expected to "go away"; However, delay in infectious diseases such as tuberculosis can affect not only the person but also his/her environment.
