Symptoms and Treatment of Chickenpox
The main symptoms of chickenpox include a mild fever and rash, with some patients experiencing headaches, coughs, and other symptoms. Treatment primarily consists of general treatment, antiviral therapy, and treatment of complications.
Does tuberculosis infect people?
Tuberculosis is a contagious disease, and hearing the term "tuberculosis" inevitably makes people nervous. However, not all tuberculosis patients are contagious. Research shows that among tuberculosis patients, only those who have tuberculosis bacteria found in sputum smear tests are contagious. With a source of infection, the tuberculosis bacteria must be transmitted to others through certain routes. Airborne transmission is the main route of transmission for tuberculosis bacteria. When a tuberculosis patient coughs, sneezes, or speaks loudly, they release a large number of droplet nuclei containing tuberculosis bacteria into the air, which can be inhaled by healthy individuals and cause infection. The degree of tuberculosis bacteria infection mainly depends on factors such as the amount of bacteria the patient expels, the severity of coughing symptoms, and the extent of contact. Therefore, when there is a tuberculosis patient nearby, we first need to understand whether they are in the active phase of the disease, that is, expelling bacteria, and whether they are undergoing anti-tuberculosis chemotherapy. If the patient has a negative sputum test or has undergone chemotherapy for a positive sputum test, such patients have very low contagiousness, so there is no need to worry too much about being infected.
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.
When to get the chickenpox vaccine?
Chickenpox primarily affects infants and children, and the target group for chickenpox vaccination is mainly 1-12 years old. During this age period, most children enter preschool or elementary school institutions, and the chickenpox virus is highly contagious, transmittable through droplets and contact. Once one child contracts chickenpox, the surrounding children are almost certain to be infected too. Additionally, since there are currently no effective medications to cure chickenpox, it is best to vaccinate within this age range, namely 1-12 years old. Adults can receive the chickenpox vaccine without age restrictions. The timing can be decided based on individual circumstances, but it is generally recommended to get vaccinated before the onset of the peak season for chickenpox, which is best before the spring and winter seasons.
Rabies symptoms
Rabies is mainly characterized by hydrophobia, fear of wind, pharyngeal muscle spasms, progressive paralysis, etc. It is divided into: the prodromal phase, the excitative phase, and the paralytic phase, with varying symptoms in each phase.
