All of us should be familiar with the disease of respiratory infections. It should be said that basically everyone may have had this disease, especially when the probability of developing respiratory infections is particularly high. So why is there a respiratory infection? Follow the editor and read down.
Why do you have respiratory infections? Because respiratory infections can cause serious physical harm to your baby, it is particularly important to understand the causes of respiratory infections. The baby's organs and bronchus are narrower than adults, so it is more vulnerable to viruses and bacteria. Infringement, then the following small series will explain in detail why the baby has respiratory infections? What are the reasons? First of all, let's first look at the causes of upper respiratory infections in babies. Upper respiratory infections often occur in winter and spring. The most important factor causing upper respiratory infections is that the pathogenic virus suspended in the air passes through the upper respiratory tract of the human body., then it will cause the patient to cough and sneeze. Even droplets that appear when the patient speaks can stay in the air for several minutes before falling to the ground. If the wind blows up the dust, it will be infectious.
Upper respiratory infections are usually transmitted in the first few days of the disease.
Additionally, the specific causes of lower respiratory tract infections are caused by viral or bacterial infections, as well as Mycoplasma and Chlamydia pneumoniae, which are associated with symptoms. These two types of respiratory infections are most commonly seen in cases of upper respiratory tract infections.
What are the symptoms of respiratory infections? We all know that respiratory infections are a common type of respiratory disease among children, which is a general term referring to inflammation from the nose to the throat. So, what are the symptoms of respiratory infections? Today, let's explore this topic together with everyone to help mothers better identify and actively treat their babies.
Firstly, let's take a look at some of the diseases that manifest in pediatric upper respiratory infections: common colds, flu, and sometimes herpangina. In severe cases, there can be purulent tonsillitis.
Additionally, let's examine some symptoms of lower respiratory tract infections in infants. Firstly, in terms of temperature, babies may exhibit symptoms of high fever, typically reaching around 39 to 40 degrees Celsius. They may also experience headaches and muscle aches, which can lead to poor appetite. When coughing, they may display dry coughing, which gradually transforms into mucopurulent bloody sputum over 1 to 2 days.
At the same time, serious babies may also have some respiratory distress, and some babies may have nausea, vomiting, abdominal distension.
Types of Respiratory Infections Respiratory infections account for approximately 90% of all infections, with viruses being the primary cause. This makes them viral respiratory infections. Due to children's particularly weak immune systems, colds, fatigue, and exposure to rain are more likely to trigger respiratory infections. So, what are the different types of respiratory infections? Keep reading.
Firstly, the infection of respiratory tract is divided into upper respiratory infection and lower respiratory infection, in which upper respiratory infection is further divided into acute respiratory infection and chronic respiratory infection.
Since each type of respiratory virus causes different infections, the symptoms experienced by the body will also vary.
Secondly, the growth of viruses in upper respiratory tract infections is very rapid. Perhaps due to the presence of certain bacteria or viruses in the baby's body, they can easily become infected when exposed to cold stimuli or other reasons, commonly leading to conditions such as bronchitis and pneumonia.
Ultimately, lower respiratory tract infections are primarily caused by Gram-negative bacteria and account for approximately 70% of infections. Lower respiratory tract infections are essentially characterized by bronchial infections such as bronchitis, chronic bronchitis, and bronchiectasis.
Is Respiratory Infection Serious for Babies? When babies fall ill, mothers' biggest concern is often the severity of the disease. Is it likely to affect their growth and development? Will the illness cause any physical defects in the future? And will it lead to serious complications? So, how severe is respiratory infection for babies? Let's take a look at this together.
Firstly, if a baby has upper respiratory tract infection, mothers need not to be particularly alarmed. This is because it's highly likely that every child will fall victim to an upper respiratory tract infection. The incidence rate of such infections is very high, with children aged four or five years old being at risk of falling ill with the condition up to four times in a year. Generally speaking, after treatment, 90% of these cases recover within a week.
Additionally, if the baby's constitution is weak, and they contract a respiratory infection with particularly strong virus pathogens, it may lead to some complications. For instance, lower respiratory tract infections can easily cause pneumonia in small babies who are unable to cough up sputum, which can clog within the airways, leading to symptoms such as rapid breathing that pose a particular danger. It is essential for mothers to take this issue seriously and promptly take their baby to the hospital for treatment.
In the end, if a baby's respiratory infection is particularly severe, it can lead to bacteria entering the bloodstream. In serious cases, the baby may develop arthritis, osteomyelitis, or even septicemia.
How to Prevent Respiratory Infections? To ensure that your baby does not contract respiratory infections, aside from understanding the causes of these diseases and seeking treatment, it is also important to implement preventive measures in daily life. Today, we will explore with mothers how to prevent respiratory infections so that these diseases are kept at bay for their babies.
1. The most important thing is to ensure that the baby gets regular exercise, often taking them outside on sunny days to boost their immune system.
Because respiratory infections are viral, it is crucial for mothers to pay special attention to hygiene and adjust the baby's clothing accordingly according to weather changes.
2. When it is particularly cold, it is better not to take your baby out and especially avoid taking them to crowded places in public to prevent cross-infection.
3. If there is a person with respiratory infection in the family, then it is better to keep the baby away from them as much as possible. If it is not possible to prevent the baby from coming into contact with the person, then it should be worn a mask at home.
4. After discovering symptoms of upper respiratory tract infection in a baby, it is essential to seek treatment promptly. Special attention should be paid to severe lower respiratory infections, as early treatment is crucial.
