Pulmonary tuberculosis
Does tuberculosis cause headaches in its initial stage?
Tuberculosis is a highly contagious respiratory disease caused by the infection of Mycobacterium tuberculosis in the lungs, generally transmitted through respiratory droplets or direct contact. When infected with tuberculosis, symptoms that often appear include low-grade fever in the afternoons, coughing, expectoration, hemoptysis, chest pain, chest tightness, and shortness of breath. Some may experience weight loss, fatigue, and night sweats. Therefore, when patients with pulmonary tuberculosis exhibit an afternoon low-grade fever, it often leads to the occurrence of headaches. Therefore, it is very common for patients in the early stages of pulmonary tuberculosis to exhibit various symptoms, primarily due to the rise in body temperature.
Does tuberculosis cause fever?
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.
Is tuberculosis contagious?
Not all cases of tuberculosis are infectious. Some tuberculosis cases are infectious in the early stages but become non-infectious after proper treatment. Patients with open tuberculosis are highly contagious because their sputum contains tuberculosis bacilli. These bacilli can be released into the air through coughing, sneezing, laughing, or loud speaking, and can cause infection when inhaled by others. Some tuberculosis patients do not have detectable bacilli in their sputum, and their infectiousness is relatively much lower.
How is tuberculosis transmitted?
How is pulmonary tuberculosis transmitted? First, we need to know the pathogen of pulmonary tuberculosis, which is the tuberculosis bacillus. Tuberculosis bacillus is a type of bacterium that can live in our surrounding environment. Pulmonary tuberculosis also needs a source of infection, that is, a patient carrying the tuberculosis bacillus. The most common source of tuberculosis infection is usually patients with secondary pulmonary tuberculosis. Then, its mode of transmission mainly includes coughing, sneezing, laughing, and talking loudly, which can release the tuberculosis bacilli from the patient into the air, spreading them through droplets. Droplet transmission is the most important route for the spread of pulmonary tuberculosis. Additionally, pulmonary tuberculosis can also be transmitted through other routes such as the gastrointestinal tract or the skin, although these methods of transmission are less common.
Symptoms of pulmonary tuberculosis
Now let me talk about the symptoms of tuberculosis. Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many organs, with pulmonary tuberculosis being the most common. The main symptoms are respiratory symptoms and systemic symptoms. The respiratory symptoms are mainly manifested as coughing, expectoration for more than two weeks, or blood in the sputum, which are common suspicious symptoms of pulmonary tuberculosis. Generally, the cough is mild, either dry or with a small amount of mucus. When cavities form, the amount of sputum may increase, and if there is a secondary bacterial infection, the sputum may become purulent. If there is concomitant bronchial tuberculosis, it will manifest as an irritating cough. About one-third of patients will experience hemoptysis, and some may experience massive hemoptysis. If the tuberculosis lesions involve the pleura, it can manifest as chest pain. Dyspnea is more common in patients with caseous pneumonia or those with a large amount of pleural effusion. These are local symptoms. Systemic symptoms mainly manifest as fever, which is the most common manifestation, often as long-term afternoon fever, meaning it begins to rise in the afternoon or evening, drops in the morning, and then returns to normal. Some patients may also experience fatigue, night sweats, loss of appetite, weight loss, etc. Women of childbearing age may experience menstrual disorders, etc.
What is tuberculosis?
Tuberculosis is a disease where the bacterium Mycobacterium tuberculosis infects the lungs. It is a persistent bacterium that grows slowly. Tuberculosis is an infectious disease and quite common historically, often referred to as consumption in the past, as mentioned in the novels of Lu Xun. In modern times, tuberculosis is relatively manageable if the infection has not developed resistance to drugs. Proper anti-tuberculosis treatment can result in a cure rate exceeding 90% on the first attempt. However, if the treatment is not adhered to correctly—if the patient stops taking the medication prematurely or does not follow the prescribed regimen—the bacteria may develop resistance, reducing the effectiveness of the treatment. This is particularly problematic in elderly patients, who might also experience adverse reactions to tuberculosis medications, making treatment difficult. Thus, while tuberculosis is generally treatable, infections with drug-resistant strains can be fatal if not managed properly.
Is tuberculosis contagious?
Firstly, pulmonary tuberculosis is contagious, but it also depends on the type. Generally, pulmonary tuberculosis is most contagious during its active phase, but some patients with fibrosis and in a stable phase are not contagious. The transmission of pulmonary tuberculosis is mainly through droplets, spread by talking, sneezing, or spitting from a tuberculosis patient to a healthy person. However, this droplet transmission has a distance requirement. We believe that a distance of more than 1 meter is relatively safe, and 2 meters is absolutely safe. To prevent the transmission of tuberculosis, it is essential to maintain a distance from tuberculosis patients, wear masks, and ensure frequent ventilation by opening windows.
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.
How long can someone with tuberculosis live?
Early detection and appropriate anti-tuberculosis treatment of tuberculosis can lead to a normal lifespan once cured. However, it is important to exercise regularly and enhance immunity, since tuberculosis may recur if the body's resistance decreases. With the increase of drug-resistant tuberculosis, treatment difficulties have intensified. If it is detected late or not treated properly and the lung damage progresses to an advanced stage, it can be life-threatening, with survival ranging from days to years. When tuberculosis involves massive hemoptysis, death can occur at any time due to suffocation or hemorrhagic shock, depending on the specific condition.
Can tuberculosis relapse?
Tuberculosis can relapse, and the answer is definitely yes. In clinical practice, we see many patients who have had tuberculosis and, years later, experience a recurrence of the disease, even multiple recurrences. However, the probability of this is generally not high. As long as everyone follows the doctor's instructions for standard anti-tuberculosis treatment and completes the full course of treatment, most patients can be cured. However, there are a few people whose treatment process is not standard, or who stop taking their medication on their own, and these actions can increase the risk of tuberculosis recurrence.
