Does tuberculosis cause fever? The answer is definitely yes. Fever is one of the most common clinical manifestations of tuberculosis. Many tuberculosis patients experience low fevers, and a minority of patients, such as those with caseous tuberculosis or tuberculous pleurisy, may experience high fevers that can recur and persist. Moreover, tuberculosis patients may sometimes also have concurrent bacterial infections, which can cause the fever to last longer and be more difficult to control.

How to test for tuberculosis

To examine pulmonary tuberculosis, it is essential to understand that it pertains to tuberculosis changes in the lung tissue, airways, bronchi, and pleura. The pathogen causing tuberculosis is Mycobacterium tuberculosis, also known as the tubercle bacillus. There are multiple tests available for people with pulmonary tuberculosis, as the disease can vary based on location and type. Therefore, such patients generally require numerous tests. The most commonly used are imaging studies for the chest, including X-rays and CT scans. In imaging studies, most patients will show some lesions, but there are instances where tuberculosis in the airways and bronchi might not be clearly visible on CT or X-rays, necessitating more invasive tests like bronchoscopy. Additionally, bacteriological examinations, such as sputum smear and pleural fluid smear, as well as culture for Mycobacterium tuberculosis, are typically conducted for patients. Nowadays, hospitals equipped with the necessary facilities conduct molecular biological tests, namely nucleic acid testing for Mycobacterium tuberculosis DNA. Furthermore, some patients with complex conditions may require a histopathological biopsy, commonly referred to as tissue sampling, at the site of the lesion to observe under a microscope for characteristic changes indicative of tuberculosis. There are also immunological tests that assist in diagnosing tuberculosis, such as the gamma interferon release assay (commonly known as the T-SPOT), tuberculin skin test, and traditional antibody tests against Mycobacterium tuberculosis.

Does tuberculosis cause fever?

Does tuberculosis cause fever? Certainly, fever can occur. Fever is one of the most common clinical manifestations of tuberculosis, which can be mild or high fever. Most cases of tuberculosis mainly present as afternoon febrile flushes, or say, an evening low-grade fever. In a few cases, such as infectious pneumonia or more severe infections like tuberculous pleurisy, there can be high fever, and these fever episodes may last a long time and be recurrent, making them difficult to control.

Can tuberculosis be cured?

Tuberculosis can actually be completely cured, primarily through anti-tuberculosis treatment. If it is confirmed to be active tuberculosis, systematic and standardized anti-tuberculosis treatment is required. Through scientific and reasonable anti-tuberculosis treatment and taking medication on time and according to guidelines, most tuberculosis patients can be cured, with a cure rate reaching 85%. The treatment includes an intensive phase of anti-tuberculosis treatment and a consolidation phase, with the total course of treatment being about six months. After being cured, it is not easy to relapse, but it is essential to take medications on time, adjust nutrition, modify work and rest schedules, and rest well.

Early symptoms of tuberculosis

In the early stages of tuberculosis, as the condition is relatively mild, many patients have no symptoms or only mild symptoms. Typical symptoms include coughing, expectoration, night sweats, fatigue, low-grade fever, poor appetite, and weight loss, but these are not specific to tuberculosis. If these symptoms persist for more than two weeks, tuberculosis should be suspected, and a chest x-ray or other examinations should be performed for further clarification. If the x-ray suggests tuberculosis, further tests such as a tuberculin skin test should be conducted to confirm the diagnosis.

Can tuberculosis be cured?

Early diagnosis and standard treatment can often cure tuberculosis. Tuberculosis requires anti-tuberculosis treatment. Effective anti-tuberculosis treatment must follow five principles: early intervention, proper dosage, combination therapy, regular administration, and full-course treatment to ensure thorough treatment. Consistency is crucial; one must not stop taking medication, substitute drugs, or alter dosages on their own, as doing so not only makes it difficult to cure the disease but also increases the risk of developing drug resistance and complicates treatment further. Additionally, it is important to supplement nutrition appropriately and maintain a healthy diet in daily life. Since tuberculosis is a chronic, debilitating disease, it is advisable to consume foods rich in calories, proteins, and vitamins. Ensuring adequate rest and sleep is vital. Engaging in moderate physical activities, such as outdoor exercises, while avoiding strenuous activities and factors that could exacerbate conditions, such as overexertion, exposure to cold, and catching a cold, is also important.
