Is bronchial asthma contagious?
Is bronchial asthma contagious? Bronchial asthma is not contagious; it is not an infectious disease. The exact causes of bronchial asthma are not very clear, primarily thought to be related to genetic and environmental factors. Bronchial asthma has a close relationship with genetics, meaning that if parents have asthma, their children and grandchildren might also develop bronchial asthma. The closer the familial relationship, the higher the chances of developing bronchial asthma compared to the general population. This genetic pattern can create the illusion to the general public that bronchial asthma is contagious, but it may be more closely related to genetics.
Is type B influenza contagious?
First, we need to understand what influenza B is. Influenza B, also known as influenza type B, is a type of influenza caused by the influenza B virus. Currently, it is classified as a class C infectious disease, which means it is indeed contagious. The main sources of transmission for influenza B are patients and asymptomatic carriers. Generally, the virus is contagious from one to seven days after onset of the illness, with the highest contagiousness occurring within the first two to three days. Influenza B is a respiratory tract infectious disease, mainly spread through the air and droplets. Most people are susceptible to influenza B.
Can asthma be cured?
So far, there is no known cure for bronchial asthma, and it is estimated that curing asthma within the next ten or twenty years will be very challenging. Therefore, any methods or medications claimed to treat or cure bronchial asthma found on any search engine cannot be trusted. We often encounter many people who, influenced by various advertisements, such as flyers, television, and even some newspapers, take medications containing powders that may control asthma temporarily. However, this can increase the risk of future control issues and cause many adverse reactions. Through these reactions, we can infer that these may contain oral steroids. Although oral steroids can indeed be used to control asthma, their use is subject to strict indications, and they are generally not the first choice for asthma control. Therefore, if you have asthma, you must seek standard treatment in a qualified hospital instead of self-medicating through any means, as this is inadvisable.
How to cure chronic bronchitis completely?
At present, there is no cure for chronic bronchitis, and most treatments are mainly aimed at alleviating its symptoms. The treatment is mainly divided into two parts, one is the treatment during the acute exacerbation phase, which means that if a patient with chronic bronchitis experiences acute worsening of symptoms such as coughing and expectoration, or if accompanied by wheezing, fever, etc., then the main treatment methods might include anti-infection measures, expectorants to relieve cough, or treatments to alleviate wheezing. Most patients with chronic bronchitis are likely in the remission phase most of the time, and the primary treatment during this phase is initially to address factors that might trigger chronic bronchitis, such as insisting that patients who smoke quit smoking, and for those who have been exposed to dust or smoke, it is crucial to resolve triggering factors and avoid contact with harmful gases or inhalation of harmful particles. The next step is to enhance physical fitness and prevent colds. Chronic bronchitis patients can engage in appropriate physical exercise based on their condition, and those who suffer from long-term recurrent infections might consider pursuing immunotherapy.
Chronic bronchitis symptoms
Chronic bronchitis is also known as "old chronic bronchitis." From the name, it can be inferred that its cough and expectoration last for a long time and its onset is slow, which can manifest as acute exacerbation. The main symptoms of chronic bronchitis are cough and expectoration, either with or without wheezing. The cough in chronic bronchitis usually occurs in the morning, meaning that the cough is more pronounced upon waking up. The sputum is generally white, sticky, mucoid, or frothy, and may occasionally contain streaks of blood but generally is not associated with coughing up blood. In addition to coughing and expectoration, a small number of patients may experience wheezing or shortness of breath. In cases where the wheezing is more pronounced, it is also referred to as asthmatic bronchitis.
Can bronchial asthma be inherited?
The etiology of asthma is still very unclear, but genetics may indeed be related to bronchial asthma to some extent. Currently, a lot of research data indicates that the incidence rate of bronchial asthma is higher among the relatives of patients than in the general population, and the closer the familial relationship, the higher the incidence rate and potentially more severe the condition could be. In layman's terms, this means that if our parents have bronchial asthma, then the likelihood of their children having bronchial asthma is higher than in the general population. However, this is not absolute; it does not mean that if a parent has bronchial asthma, their children will definitely have it. The relationship is not very certain, and the genes related to bronchial asthma are also not very clear at present. Bronchial asthma is also related to many other factors.
The difference between sarcoidosis and tuberculosis
Sarcoidosis and tuberculosis, although only differing by one character in Chinese, are completely different diseases. Sarcoidosis and tuberculosis share some similarities, such as their pathological changes often involving granulomas. However, in tuberculosis, the granulomas are typically caseating, while in sarcoidosis, they are non-caseating. Tuberculosis shows characteristic features under pathological examination, whereas the diagnosis of sarcoidosis is one of exclusion, requiring the ruling out of other various granulomatous diseases. Secondly, their causes are also different; tuberculosis has a very clear cause, being an infectious disease caused by the tuberculosis bacterium. Meanwhile, the cause of sarcoidosis has not been identified clearly and may be related to a variety of factors including genetics, environment, and chemicals, among others. Additionally, the clinical manifestations of both sarcoidosis and tuberculosis are not specific, and both diseases can present symptoms like coughing, expectoration, chest pain, hemoptysis, low or high fever, weight loss, and night sweats. Thus, it is quite difficult to differentiate between sarcoidosis and tuberculosis based on symptoms alone. Moreover, their treatments differ; sarcoidosis is mainly treated with corticosteroids, while the primary treatment for tuberculosis involves anti-tuberculosis therapy.
Can you get tuberculosis on your own?
This question can be interpreted in two ways. First, whether every individual could potentially contract tuberculosis (TB) – to that, the answer is yes. Tuberculosis is a contagious disease, and we are all susceptible to the TB bacterium. Therefore, there is a chance, in our lifetimes, to be infected by the TB bacterium and consequently develop TB. The second interpretation revolves around whether a person could suddenly develop TB without specific reasons. Generally, this does not happen. In other words, a typical person would not contract TB unless they have been exposed to the TB bacterium. This means one does not contract TB arbitrarily; it occurs only after coming into contact with TB patients or the TB bacterium, leading to an infection in the lungs and resulting in TB.
Can tuberculosis be fatal?
Can tuberculosis be fatal? Of course, the answer is yes. Many diseases can lead to death, even a common cold can potentially result in death, let alone tuberculosis, which is an extraordinary illness. Currently, the mortality rate for tuberculosis patients is relatively low because the treatment for tuberculosis has improved significantly compared to the past. However, there are still a small number of patients who, due to untimely treatment of tuberculosis, discontinuation of medications on their own accord or non-compliance with medical advice, or who have other serious underlying diseases, may not tolerate the tuberculosis treatment. As a result, they could potentially die from adverse reactions to the tuberculosis medications.
How to completely cure bronchial asthma?
How can bronchial asthma be cured? First, we need to recognize that once bronchial asthma is diagnosed, it is a lifelong disease and is recurrent throughout one's life. So far, it cannot be cured. Many people on television or in magazines claim that traditional Chinese medicine, ancient secret recipes, or other means can cure bronchial asthma, suggesting various treatments. However, these are false advertisements and should not be trusted. Bronchial asthma can be controlled, meaning that it is currently incurable and can only be managed with medication. There are now many treatment options for bronchial asthma. As long as patients seek standardized treatment at legitimate hospitals, the majority of those with bronchial asthma can receive proper treatment and management.
