Mycoplasma pneumonia prominent symptoms
Mycoplasma pneumoniae is most commonly responsible for lung infections, which we also refer to as mycoplasma pneumonia. The incubation period for mycoplasma pneumonia generally ranges from one to three weeks. The onset of the disease is quite varied, typically beginning gradually. Most patients primarily exhibit symptoms of low fever and fatigue, but a small proportion may experience a sudden onset of high fever, which can persist for an extended period. Additionally, the most pronounced symptom is a dry cough, characterized by intense coughing with little to no phlegm and long duration, sometimes lasting over a month. Moreover, some patients may also experience a sore throat and blood-streaked sputum. A very few patients, in addition to respiratory symptoms, may exhibit extrapulmonary symptoms primarily presenting as measles-like rashes. Very rarely, complications such as pericarditis, myocarditis, and meningitis may occur, manifesting corresponding symptoms, although these cases are generally very rare.
Can asthma be cured completely?
We often refer to asthma as bronchial asthma, which, whether it is cough variant asthma, allergic asthma, or caused by other factors, has not yet a cure found to date. It is now generally believed that bronchial asthma can be controlled, which means that as long as patients with bronchial asthma receive standardized treatment in reputable hospitals, most can be controlled and will not suffer from recurrent attacks. So far, there is no cure found, and all advertisements using Traditional Chinese Medicine or ancient secret remedies or any other means claiming that asthma can be cured are false. These are not to be trusted, and many asthma patients often suffer because they take some medications containing oral corticosteroids under these false beliefs. While these might control asthma in the short term, they are detrimental to the long-term management of asthma, and prolonged use of such non-standard corticosteroid treatments can lead to many adverse reactions, such as drug-induced Cushing's syndrome and medication-induced diabetes, among others.
Is tuberculosis easily contagious?
Whether tuberculosis (TB) is easily transmitted primarily depends on the source of infection, which refers to the TB patients and the amount of Mycobacterium tuberculosis in their sputum. If TB bacilli can be detected in their sputum, and the quantity is substantial, then their infectiousness is indeed higher. However, if the TB patient has undergone treatment, or if there are only a few TB bacilli in their sputum, or none at all, then their infectiousness may not be as significant. The second factor is the mode of transmission, which mainly occurs through the respiratory tract. If TB patients can be isolated timely, or if they wear masks, and their sputum is properly managed, for example by wrapping the sputum in paper and burning it, then they are less likely to transmit the disease to others. TB generally involves susceptibility issues; even if someone has been vaccinated with BCG or the TB vaccine, they can still be reinfected. Therefore, controlling these three transmission pathways is essential to minimize the risk of contracting TB.
How to treat chronic bronchitis?
How to treat chronic bronchitis, first of all we need to know that chronic bronchitis can be divided into two phases, one is the remission phase, the other is the acute exacerbation phase. Since most patients are in the remission phase most of the time, that is, their symptoms of cough and expectoration are relatively stable, more or less the same every day, with no significant change in the amount and nature of the sputum, no purulent sputum, no significant increase in sputum, and no fever or other symptoms of infection. In such cases, the first step in treating chronic bronchitis patients is to target some possible causes of their condition, such as smokers must quit smoking. Most chronic bronchitis patients experience some relief in cough and expectoration after quitting smoking. Furthermore, some patients' chronic bronchitis may be due to exposure to dust or irritant gases. It is crucial to avoid contact with these harmful gases as much as possible. In addition, patients in a stable condition should engage in physical exercise, enhance their physical fitness, and prevent colds. Some chronic bronchitis patients who frequently suffer from respiratory infections can consider using immunomodulators or some traditional Chinese medicine to regulate immunity and enhance resistance. Additionally, since chronic bronchitis can acutely exacerbate, which means the patient’s condition has changed, their cough and expectoration frequency may increase, the amount of sputum may increase, or there may be some purulent sputum, or fever and other symptoms. In such cases, the primary treatment may still be infection control, commonly using antimicrobial drugs, often referred to as anti-inflammatory drugs. The types of anti-inflammatory drugs are numerous, the most common ones include penicillin, erythromycin, levofloxacin, amoxicillin, and some cephalosporins. In such cases, it is necessary to choose medication under the guidance of a doctor. Additionally, in these situations where the patient’s cough and expectoration are worsened, and sputum increases, medications for cough suppression and expectoration, commonly known as expectorants and cough relievers, are also needed. There are some proprietary Chinese medicines, such as licorice preparations, and Western medicines such as bromhexine and ambroxol as well. Moreover, a very small portion of patients may experience wheezing, meaning some patients might also have symptoms like chest tightness and shortness of breath. In such cases, it would be necessary to use bronchodilators under the guidance of a doctor, such as theophylline or doxophylline, and these medications must be used under medical supervision.
Can pneumonia heal by itself?
Pneumonia is generally not self-healing; only a few pneumonia cases caused by specific pathogens, which lead to milder infections, can heal by themselves, such as pneumonia caused by Mycoplasma pneumoniae, which is self-limiting and can heal. However, most cases of pneumonia require standard treatment, such as pneumonia caused by Streptococcus pneumoniae and infections caused by Staphylococcus aureus. Therefore, if diagnosed with pneumonia, it is essential to seek immediate medical attention at a hospital. Relying on self-healing is unrealistic since self-healing cases are rare, and most pneumonia cases require standard treatment to recover.
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.
