Tuberculosis (TB), a highly contagious disease caused by airborne germs, poses a significant threat to global health. While primarily affecting the lungs, TB can also target other vital organs such as the brain, kidneys, and spine. If left untreated, TB can be fatal. In this article, we delve into the key aspects of TB, including its prevalence, risk factors, treatment options, and prevention strategies.
Prevalence and Risk Factors
Southeast Asian countries bear a substantial burden of global TB cases, accounting for 44% of all reported cases. Malaysia, ranked 76th worldwide, is classified as a medium-to-low level endemic country. In 2021 alone, Malaysia recorded 21,727 TB cases and 2,288 TB-related deaths.
While anyone can contract TB, certain individuals face a higher risk. Close contacts of an infectious TB patient, whether at home or in the workplace, are particularly vulnerable. Additionally, people with compromised immune systems, such as those with diabetes, severe kidney disease, cancer, or HIV-positive individuals, are at increased risk. Chronic smokers are also more susceptible to contracting TB.
Treatment Options
Treating TB requires a more extended course of action compared to other bacterial infections. Active TB infections are typically addressed through a combination of antibacterial medications administered over a period of six to 12 months. Treatment regimens consist of an intensive phase lasting two months, followed by a continuation phase lasting either four, seven, or ten months.
Patients undergoing treatment can expect positive changes within two to four weeks, depending on the severity and organ involvement. While some individuals may experience mild side effects like skin itchiness and dizziness, others may encounter more severe complications necessitating hospitalization and temporary discontinuation of treatment. It is important for patients to consult healthcare professionals if they encounter any adverse reactions during treatment.
Prevention Strategies
The Bacille Calmette-Guérin (BCG) vaccine currently stands as the only available vaccine against TB. This vaccine is routinely administered to newborns as a preventive measure. Additionally, health authorities must be notified of all confirmed TB cases to enable contact tracing by healthcare personnel.
Individuals displaying symptoms suggestive of TB, such as persistent coughing for more than two weeks, accompanied by blood-tinged sputum, fever, and loss of appetite, should undergo screening for active TB. Sputum samples are collected for three consecutive days and can be analyzed at Klinik Kesihatan or private healthcare facilities.
Recognizing TB Symptoms
TB manifests differently depending on the affected organ. Common symptoms include general weakness or malaise, weight loss, fever, and night sweats. In cases where the lungs are affected, individuals may experience chest pain and cough up blood. TB of the brain may lead to meningitis and present symptoms such as headaches, decreased consciousness, and neck stiffness. Tuberculosis of the spine can cause localized pain and tenderness, muscle stiffness and spasms, cold abscesses, and prominent spinal deformities.
Promoting Awareness and Collaboration
To combat the global impact of TB effectively, it is crucial to raise awareness about the disease’s prevalence, risk factors, treatment options, and preventive measures. Collaboration between healthcare professionals, researchers, policymakers, and communities is essential in developing comprehensive strategies to prevent the spread of TB and improve patient outcomes.
Tuberculosis remains a pressing global health concern that demands our attention and action. By understanding its prevalence, risk factors, treatment options, and prevention strategies, we can work towards reducing the burden of this disease and ensuring a healthier future for all.
