Does whooping cough infect adults?
Pertussis, a respiratory infectious disease, can also be transmitted to adults, although the chances are generally small. It mostly occurs in adults with low immunity and those who are frail and ill when they come into contact with the pathogen. The incubation period is about two to three weeks, during which paroxysmal cluster-like coughing occurs, causing facial redness and a runny nose. Some may also experience nausea and vomiting. It is necessary to check chest X-rays, routine blood tests, and sputum pathogen cultures for diagnosis. Early detection and treatment are crucial to prevent other complications.
How is whooping cough diagnosed?
If the body has chronic cough symptoms that do not heal over time and recur frequently, it is suspicious of pertussis infection. To confirm this disease, corresponding auxiliary examinations are needed, such as a complete blood count and sputum culture. If Bordetella pertussis or Corynebacterium diphtheriae are cultured from the sputum, a diagnosis can be made. It is also necessary to combine clinical symptoms and promptly use sensitive antibiotics and cough-relieving expectorant drugs for symptomatic treatment, adjusting the mindset to avoid mental tension.
Can tracheitis cause a fever?
Tracheitis, in its acute inflammatory phase, can cause symptoms such as fever, although not all cases of tracheitis will lead to a fever. Fever is merely a manifestation of inflammation within the body, and respiratory infections are prone to this symptom. It is necessary to conduct timely examinations, in conjunction with clinical symptoms and supplementary tests, to implement appropriate treatments and interventions. If the body temperature exceeds 38.5 degrees Celsius, it is possible to administer antipyretic medication for symptomatic treatment, such as ibuprofen or acetaminophen. For acute tracheitis, choosing antibiotics to control the infection is also advised. (The use of medications should be under the guidance of a doctor.)
What are the symptoms of whooping cough?
Pertussis, also known as whooping cough, typically manifests as paroxysmal coughing. During the acute phase, the cough is spasmodic, and some patients may produce sounds similar to a dog's bark or a rooster's crow. This type of cough can lead to complications such as a runny nose, tearing, facial flushing, red ears, and vomiting. Diagnosis should be confirmed through routine examination of secretions. During the acute phase, symptomatic treatment should be administered, along with the selection of macrolide antibiotics to eliminate the pathogenic bacteria, which are mostly due to infection by Corynebacterium diphtheriae or Bordetella pertussis. Patients should adjust their mindset, drink plenty of warm water, and maintain clean indoor air.
How to check for bronchiectasis?
How to check for bronchiectasis: generally, corresponding physical examinations and laboratory tests are used for diagnosis. Early physical examinations may not show positive signs. When the condition is severe or secondary bacterial infection occurs, fixed and persistent moist rales can be heard in the affected areas. Some patients may show signs of oxygen deficiency, such as clubbing and cyanosis. During acute infections, routine blood tests will show increased white blood cell counts and neutrophil counts. Sputum examination may reveal elastic fibers and pus cells. A chest X-ray can show thickened and disordered lung periphery, and typical lesions may appear as honeycomb-like curly shadows.
Is bronchiectasis easy to treat?
Bronchiectasis is a complication mainly caused by chronic inflammation of the respiratory tract and is clinically difficult to treat. Symptoms can be alleviated through certain medications or physical manipulations. First, it's important to maintain clear airways and choose medications that can dilute mucus. During the acute phase of inflammation, antibacterial drugs should be chosen for treatment, such as penicillin, which can be administered via muscle injection or intravenously. Surgery is the only curative treatment for bronchiectasis. (Medication use should be based on specific circumstances and under the guidance of a doctor.)
How is bronchitis diagnosed?
In clinical practice, if bronchitis is suspected, it is not very difficult to confirm the diagnosis. It generally involves combining clinical symptoms with results from routine blood tests, chest X-rays, or CT scans for a definitive diagnosis. Most cases will show thickened bronchial or lung markings, and an increase in the total number of white blood cells in the blood. The main symptoms include coughing, expectoration, and difficulty breathing. Diagnosis can be confirmed by combining personal medical history, physical signs, and laboratory test results, allowing for timely anti-inflammatory treatment.
Is tracheitis contagious?
Tracheitis is a respiratory infectious disease that is contagious, especially among children with weak constitutions and elderly patients with multiple ailments. Close contact with individuals suffering from tracheitis might lead to the transmission of the disease through airborne droplets to those with low immunity. Hence, it is recommended that individuals suffering from this disease wear masks to reduce viral transmission and, if possible, undergo isolation treatment. Drinking plenty of water, resting, avoiding smoking and alcohol, consuming a light diet, and seeking timely treatment typically lead to full recovery within about a week.
Causes of bronchitis
Bronchitis is mostly caused by the invasion of pathogenic bacteria into the body, affecting the bronchi. Common pathogens include Streptococcus pneumoniae, rhinovirus, adenovirus, mycoplasma, chlamydophila, and it might also be due to infection by pathogenic bacteria such as Bordetella. It often occurs when the body's immune system is compromised, due to staying up late, being exposed to cold, lack of sleep, or getting wet in rain. During the acute phase, symptoms such as high fever, chills, coughing, spitting phlegm, and breathing difficulty may occur. It's important to detect and treat it early to prevent it from turning into chronic bronchitis.
Mycoplasma pneumoniae elevated causes
Hospital tests show elevated levels of Mycoplasma pneumoniae, indicating an infection with this pathogen in the body. This can cause symptoms such as sore throat, cough, fever, chest pain, and difficulty breathing, although symptoms may not be typical in some patients. Regardless of the presence of these symptoms, once a Mycoplasma pneumoniae infection is confirmed, it is necessary to choose sensitive antimicrobial drugs to control the infection. Typically, macrolide antibiotics such as Roxithromycin, Azithromycin, or Clarithromycin can be selected. Generally, one of these is chosen and used over a course of treatment. A re-examination should be conducted seven to ten days later. During the treatment period, avoid consuming spicy foods, seafood, and fried or pickled foods. (Specific medications should be taken under the guidance of a physician.)
