Introduction
Tuberculosis remains one of the deadliest infectious diseases in the world today. Despite advances in medicine, it continues to hit low resource countries hard, including Cameroon. In 2025, 26,924 cases were recorded there, illustrating the scale of the public health challenge. This persistence is explained by a combination of social, economic, and medical factors that hinder prevention and complicate treatment. Understanding its causes, symptoms, and impact is essential in order to combat it more effectively.
A Disease Driven by Multiple Factors
Tuberculosis is caused by the Koch bacillus, an infectious agent capable of remaining inactive in the body for a long time. Only 5 to 10 percent of infected individuals develop an active form of the disease during their lifetime, but this risk increases significantly in the presence of aggravating factors. A weakened immune system is a major determinant. People living with HIV are particularly vulnerable because their bodies are unable to contain the infection. Added to this are factors linked to living conditions such as malnutrition, overcrowding, poverty, and limited access to healthcare. These realities, common in many areas, create favorable conditions for the spread and worsening of the disease. Tuberculosis therefore appears not only as a medical condition but also as a reflection of social inequalities.
Severe Symptoms and Consequences
Tuberculosis is transmitted through the air and mainly affects the lungs. It is characterized by a persistent cough, sometimes accompanied by blood, fever, night sweats, intense fatigue, and weight loss. However, it can also affect other organs such as the kidneys, spine, or brain, making some forms of the disease more complex and dangerous. Its consequences are numerous. From a medical perspective, it gradually weakens the body and can lead to irreversible damage or even death in the absence of treatment. On the social and economic level, it deeply disrupts the lives of patients. The treatments, which are long and demanding, often result in prolonged absences from work or school, thereby worsening poverty. In addition, stigma and social isolation intensify the psychological suffering of affected individuals, making tuberculosis as much a social disease as a biological one.
Prevention and Control: Effective Solutions Exist
Despite its severity, tuberculosis can be prevented and cured. Prevention primarily relies on the BCG vaccine, which protects children against severe forms of the disease. Early screening is also crucial in order to identify cases quickly and limit transmission. Improving living conditions plays a fundamental role. Proper ventilation of living spaces, reducing overcrowding, and ensuring adequate nutrition all help slow the spread of the disease. Finally, strict adherence to treatment is essential. Any interruption encourages the emergence of drug resistant strains that are much harder to treat. Combating tuberculosis therefore requires a comprehensive approach combining medical, social, and educational measures.
Conclusion
Tuberculosis remains a major public health emergency and a reflection of the vulnerabilities within our societies. In Cameroon as elsewhere, it thrives where inequalities persist and access to healthcare remains limited. Yet effective solutions exist and have already proven successful. The key lies in collective mobilization that combines prevention, screening, and strict treatment adherence. It is essential to strengthen public health policies and improve the living conditions of populations. Fighting tuberculosis also means fighting poverty and social exclusion. Acting today means saving lives and building a healthier and more equitable future.
